Installing a geyser: rules for installation and connection, replacement and setup with your own hands (in an apartment or private house)

Instantaneous gas water heaters are a traditional attribute of old housing stock. This type of equipment is little known to owners of apartments in high-rise buildings with centralized hot water supply. However, the owners of Khrushchev buildings still actively exploit it. Not all of them know how to install a gas water heater in an apartment.

Agree, this issue needs a thorough analysis. Illiterate installation of a gas processing unit will result in a serious threat. The information contained in our very useful article will help you eliminate the slightest risks. We will introduce you to all the intricacies and details of the installation process.

The carefully verified and systematized information we present is supported by photo collections and videos. With us you will receive complete answers to all possible questions that arise when connecting gas units.

Installation work

The instructions for installing and connecting a gas water heater look like this:

If the described installation work seems complicated to you, or you are simply not confident in your abilities, then you can always turn to specialists who will do everything quickly and efficiently. The average cost of their services looks like this:

• Installation of a domestically produced geyser – 2,400 rubles;
• Installation of a foreign-made geyser – 3,700 rubles;
• Installation of a chimney - 1000-1300 rubles.

When heaters are not allowed to be connected

In some cases, the use of geysers is prohibited. This applies to:

• One-room apartments in which the living room is combined with a kitchen.
• Living rooms, bathrooms or loggias. Heaters must not be used in these areas.
• The length of water and gas hoses is more than 2.5 m.
• Walls adjacent to the living room. You cannot hang a speaker on them.
• Rooms with missing ventilation slots.

It is important to remember that spontaneous installation of gas equipment entails administrative and criminal liability, the amount of which is determined depending on the consequences. Thanks to the columns, you can enjoy water at a comfortable temperature regardless of the time of year.

Although strict requirements are applied to the installation, this is necessary in order to avoid disaster. Therefore, it is better to immediately carry out the procedure in accordance with all the rules and avoid additional expenses for moving the column and reconnecting the gas

Requirements for installing a geyser

In an apartment, a gas water heater is usually installed in the kitchen

When installing a gas water heater, you need to think about where the water heater will be located. Poor placement may result in fire or fuel leakage.

Room

Safety standards prohibit placing the unit in a living room, children's room or living room. The room where the heater will be located must be adjacent to an external wall that has a window opening of sufficient area (0.03 m2 per cubic meter). If an ignition incident occurs, the explosive flow will break the glass and escape outside. The window also helps to ventilate the boiler room.

Installation of speakers is allowed in the following types of premises:

• basement and other technical rooms with an external wall and a window opening;
• kitchen, provided that the door has a built-in ventilation grille;
• combustion room, including an extension;
• corridor if other options are unavailable.

The ceiling height in the room where the heater is installed must be at least 2 m. If a boiler or other unit is also located there, the minimum figure increases to 2.5 m. The volume of the room must be more than 7.5 cubic meters.

Ventilation and chimney

There should be a ventilation hole next to the column

The room must be provided with good ventilation. Every hour, an amount of air equal to three times the volume of the room should be removed from it. The used air is removed through the shaft. If there is no channel in the building, the pipe is brought outside separately. Fresh air masses come from neighboring rooms through the lower door shutter or a grille built into it. In case of severe gas pollution, you need to open the window. If the column is placed in a room with a gas-fired boiler, there must be an additional inflow for combustion.

The column must be connected to the chimney channel using a steel pipe with walls no thinner than 0.5 mm. The material can be galvanized or enameled. Stainless steel can be used. Aluminum corrugation should not be used under any circumstances.

The channel must have a diameter not inferior to that of the outlet column pipe. The vertical fragment connected to the water heater must be long enough (at least 0.25 m). If the wall is made of flammable material, the areas located next to the pipe must be sheathed with metal sheets. In this case, the distance to the flue should be at least 10 cm. For non-combustible wall structures, it can be reduced to 5-7 cm.

The total length of the connecting fragments should not exceed 3 m. Up to three right angle turns can be included in the design. If the diameter of the shaft allows connecting the boiler and heater, there should be 0.75 m of space between the connections. It is possible to connect devices one by one to the same chimney, provided that the pipe cross-section and the size of the gap between taps are taken into account.

Fire and technological indentations

Requirements for the location of the column relative to furniture and other appliances

If the wall is made of wood or other flammable material, a 1 mm thick steel covering must be reinforced between it and the column. You can also use basalt cardboard. The edges of this protective layer should extend beyond the boundaries of the unit by 0.7 m at the top and 0.1 m on the other sides. If the column is located in a separate non-residential room (not in the kitchen), a 3 mm thick asbestos sheet is also suitable for installation.

The distance from the front of the heater to the housings of other devices, pieces of furniture, and wall surfaces must be at least 1 meter. For other sides, the normalizations are as follows:

• bottom – 0.3 m;
• top – 0.45 m;
• from the side parts - 0.15 m.

Fire safety indentations.

The speaker can only be attached to a wall that is finished with non-combustible materials. This is required by the standards rules. If it is impossible to comply with this measure in a wooden building, a special partition is laid between the wall and the column.

Suitable materials:

1. made of roofing steel: maximum millimeter thickness.

2. made of mineralite slab, maximum one centimeter thick.

3.made of basalt cardboard.

4.made of sheet asbestos, three millimeters thick.

Attention! Asbestos structures generate dust that is harmful to health, so they cannot be used in homes, but this option is acceptable in boiler rooms.

The material under the column, providing protection from fire, should be ten centimeters larger than the device on the sides, seventy centimeters on top.

Requirements for clearances from walls, furniture, etc.:

1.from the sides by 15 centimeters.

2.from the bottom side by 30 centimeters.

3.from the top by 45 centimeters.

4.The front space should be over a meter.

5.The gas stove and the horizontal removal of the appliance have a distance of ten centimeters.

6. The vertical distance to the chimney opening is three meters.

Attention! The column should not be installed close to the stove, as the released fats will eventually cover the body of the device.

If a gas water heater is not provided

In a house where the installation of gas equipment, such as a stove, is permitted, the installation of a water heater may be prohibited. This restriction applies to houses with more than 11 floors. No regulatory authority will issue permission to install a water heater in such an apartment, as this is dangerous for the residents.

In addition to the number of floors, redevelopment may be a reason for refusal. Studio apartments are not suitable for installing gas equipment, since the devices must be installed in non-residential premises.

If the kitchen is combined with a living room, this makes the use of gas appliances illegal. These limitations must be taken into account before redevelopment. The same can be applied to apartments where there is no kitchen or is shared.

If the house does not fall under these restrictions, then it is necessary to collect a package of documents to register the device.

The procedure is as follows:

1. Write an application to the gas distribution company.
2. Get a plan from the BTI or Rosreestr.
3. Provide an extract from Rosreestr confirming ownership.
4. Contact a specialized organization to draw up a project.
5. Find certified specialists from an organization that has access to gas work.

After this, specialists will make an insert into the gas pipe, connect the device and put the water heater into operation.

It is highly not recommended to install a geyser yourself, bypassing the legal order. These actions not only lead to fines, but also put people's lives at risk.

If the column has already been installed before

When changing a water heater in case of malfunction, the device passport must also be replaced. If you install a gas water heater yourself, then the passport of the new device will not contain notes on commissioning and inspections.

According to fire safety requirements, gas equipment in homes must be inspected annually. Unauthorized replacement of a water heater will not go unnoticed and most likely the device will be turned off and sealed

After receiving the comment, it will be necessary to reconnect the column, inviting certified specialists.

Their responsibilities include inspecting the ventilation system. In older homes, they may become clogged with debris. It is dangerous to operate clogged ventilation ducts. This can cause carbon monoxide poisoning, which can be fatal. If the decision to install the water heater yourself is made, then first of all you need to check the ventilation.

Preparing consumables

Installing a speaker will cost a little less if you buy some things in advance. Here's what you'll need to get before the experts arrive:

1. A piece of steel pipe with a wall thickness of at least 1 mm, through which the column will be connected to the chimney. The diameter must be specified in the instruction manual supplied with the device. Some models have this part included.
2. A rosette ring that will allow you to decorate the inlet of the chimney.
3. Water filter. If its quality is satisfactory, an ordinary household coarse filter, commonly called a mud filter or oblique filter, will do. If the water contains a large amount of hardness salts, you will need a filter with a softening effect. Without it, the column will have to be descaled very often.
4. An installation kit consisting of the necessary fittings, pipeline parts (angles, tees, adapters, couplings), sealing material and fittings.
5. Gas hose.
6. Drills for concrete work and dowels.

Also, before the installers arrive, it would be a good idea to check that the water heater is complete if you forgot to do this in the store.

Before inviting professionals, make sure that the root valves on the water supply lines are tight. Sometimes they present an unpleasant surprise, due to which the installation process is not only delayed, but also somewhat more expensive.

What tools and materials will be needed?

Here's what's required during installation:

• Open-end wrench 27/30.
• Adjustable wrench – 2 pcs.
• Open-end wrench 32/36.
• Unipack type sealant.
• Tow or FUM.

The items listed above, in principle, are always at hand. But, specifically for installing the speaker you will have to purchase:

• Galvanized pipe with a thickness of 1 mm. It can come complete with a column. If not, then the manufacturer’s instruction manual will indicate its diameter.
• Rosette ring - required when arranging the entrance to the chimney.
• Gas hose is standard. The dimensions will be indicated in the design documentation.
• Dowels with which the speaker will be mounted on the wall.
• Coarse water filter - the service life of a new geyser directly depends on its quality.

Selecting a location

You can install the speaker on a glazed balcony

The main restrictions are related to fire hazards: hence the ban on placing units in living rooms, too cramped spaces and where sufficient ventilation is not provided. The following rules follow from this:

• the column cannot be placed above the hob (including electric stoves);
• It is not allowed to hang the unit on a wall bordering a living space;
• you cannot install a dispenser when a long bendable line (250 cm or more) is required to turn it on; however, it is permissible to lay a combined pipe consisting of a flexible hose and a fragment welded to the gas supply steel lines;
• placement in a balcony room with a chimney leading outside does not contradict sanitary standards, but makes it difficult to install pipelines.

Gas supply routes should not be laid in places where chemically aggressive compounds are likely to enter. Transit pulling at a height of more than 2 m is permitted if there are no reinforcing and detachable elements on the path. Steel pipes that pass through wall structures and floor slabs must be equipped with sleeve components at the entry and exit points.

The gas supply pipe can be laid blindly in grooves or openly along the wall surface. In the latter case, the possibility of access to the supply route must be considered. It can be laid in a box with removable inspection hatches along the entire length.

Types and designs

According to their design, speakers are divided into two types:

1. With an open chamber that takes air from the room. Its movement occurs due to natural traction.
2. With a closed camera. Air is supplied into it by a turbine, and combustion products are initially isolated in the housing.

The difference in design determines the choice of certain types of chimneys.

They are made from the following materials:

• ceramic pipes laid in brick shafts;
• stainless steel with or without insulation (sandwich);
• enameled iron for internal lining;
• corrugated aluminum pipe.

Each option has its own service life, price, level of reliability and safety.

Which one is better to choose?

There are several criteria that need to be followed when choosing a smoke removal system:

1. The coaxial type is used to equip closed-type furnaces. It consists of a double pipe, one draws in air, and the second removes smoke.
2. Monolithic pipes are used when installing open-type columns. They are installed along walls and ventilation shafts.
3. A flexible corrugated channel serves to discharge gas into a common chimney directly from the column. It can be used on turning areas when the temperature of the removed products decreases.

How to install equipment

It is necessary to comply with the requirements and take into account the placement standards:

• The kitchen area should be from 7.5 square meters. m.
• Ceilings with a height of at least 2 m.
• The diameter of the chimney opening is from 120 mm.
• Mounting is carried out on a wall made of brick or concrete (non-combustible materials). For additional protection, galvanized sheets (1 mm thick) and thermal insulation are installed.
• First of all, a gas shut-off valve is installed. It is painted yellow and left freely available.
• The minimum pressure in the system is from 0.1 atm.
• The distance from the stove is at least 10 cm.
• It is allowed to connect the outlet pipe only to a chimney or a special channel in the wall. Ventilation connections are prohibited.
• Distance from the floor - from 1 meter.
• The room should have natural ventilation (window, vent).

What you need for work:

• If it is not included in the kit, then buy a galvanized pipe (from 1 meter) to remove combustion products.
• Purification filter to “soften” water and reduce the amount of impurities.
• Gas hose.
• Fitting.
• Dowels.
• Drill.
• Open-end wrenches.
• Sealant.
• Fum tape.

How to organize the process yourself:

• Measure the distance between the column fasteners. Mark the hole for drilling on the wall.
• Use a drill or hammer drill to make holes and install dowels or hooks; they are usually supplied in the kit.
• Install the housing onto the mountings.
• Connect water hoses to the pipes, connect the other ends to the column fittings. You can use flexible or PVC hoses no larger than 2.5 meters.

• Now check the strength of the connections. To do this, turn on the water and see if there is a leak.
• Install the chimney pipe. Place one end on the housing pipe, and lead the other to the chimney opening. Make sure there are no gaps. They are insulated with sealant.

Before organizing a chimney, it is recommended to check the presence of draft. This can be done with the help of a burning match, the flame of which, when brought to the chimney, should deviate to the side.

• When using a coaxial pipe, it is led into a hole in the wall.
• The last thing to do is connect to the gas main. This work is best left to specialists.

Upon completion of work, the equipment is checked:

• Open the fuel supply valve.
• Lubricate the connections with soapy water to prevent leaks.
• Tighten the clamps, install clamps if necessary.

Chimney organization

Ventilation must be working; it’s good if there is an exhaust hood. So, if there is a leak at night, proper ventilation can save the lives of apartment residents.

When arranging a chimney, keep in mind that the length of the pipe should not exceed 3 meters. No more than 3 bends are allowed. When using corrugation, it is necessary to prevent its sagging, which may interfere with the removal of smoke. All connections are checked for leaks.

Installation and wiring instructions

Before fixing and connecting the column with your own hands, buy 3 ball valves - one gas, 2 water plus connectors with a cap washer - American. The diameter of the fittings is ½” (DN15). Fastening elements are supplied with the water heater.

Connecting a water heater to the communications of a private house

Recommendation. If there is no filter at the cold water supply inlet, purchase a mud filter and place it in front of the inlet pipe of the device.

How to install the speaker yourself:

• Place the heater against the wall in the selected location and mark the outline of the housing. After measuring the distance to the mounting points, drill holes. Mount the bracket or install hooks (the method of hanging depends on the model of the unit).

• Attach the water heater, install the chimney according to the rules. Enter the round channel into the brick shaft using an adapter, and seal the joint with asbestos cord.
• Screw the American connectors to the fittings of the device, then the taps. Be careful not to confuse the gas pipe with the water pipe.

  
  Some manufacturers indicate the purpose of the fittings on the body; in general, follow the factory instructions

• Connect the cold and hot water supply, open the common valve and thus check the tightness of the joints. If there are no leaks, connect the gas pipe after lubricating the sealing gasket with grease.
• Test the gas pipeline for permeability - open the shut-off valve and wash the connections with a sponge. Bubbles will appear at the leak site.

Starting and checking water heating for DHW is done according to the manufacturer’s instructions, but only after the device has been put into operation by a representative of the supplier organization. When it is necessary to replace the device, the procedure begins with dismantling, then work is carried out in a similar order.

Comment. It is allowed to supply water and gas to the device with flexible hoses no longer than 2.5 m. But with this connection scheme, the number of joints increases; it is better to connect the pipes to the heater directly, through taps and American connectors.

Installation of the flueless (turbocharged) version of the dispenser with automatic ignition differs in the way the flue is laid - horizontally through the wall to the outside. A double-walled coaxial pipe is placed with a slight slope towards the street so that the resulting condensate drains. The device must be connected to the mains and grounded - mount a socket nearby, powered through an 8 A circuit breaker, as shown in the diagram.

Start-up and commissioning

Before starting the column, check the tightness of all connections, make sure that water is not leaking anywhere and gas is not poisoning. You can check the connections on the gas pipe using soapy water. When all the connections have been made, the joints and fittings are moistened with a soap solution, and then the valve for the gas supply is opened. If there are no bubbles, then the line is sealed.

The necessary work to start the column is carried out according to the manufacturer's instructions and strictly in the specified sequence for the first start. It is better to entrust the burner settings to a specialist.

The main task is to determine the optimal gas pressure by tightening the adjusting bolt, and by adjusting the damper to determine the air supply. It is almost impossible to make adjustments without a pressure gauge

It is important to know exactly the pressure in the gas line when idle and when the column is turned on at maximum. In dynamics, the pressure should not exceed the permissible threshold established by the manufacturer for this water heater

Ideally, the optimal operating pressure should be established, and the burner flame should always remain with a uniform blue glow without yellow tints.

Setting up the hydrothermal control unit comes down to setting the optimal values ​​for the maximum and minimum water temperatures at real pressure values, which vary greatly for different houses and apartments.

Rules

Before installing a geyser yourself, you should study the special standards and requirements.

There are two categories of work:

1. From scratch.
2. Replacement.

The first option requires a project. The pipe is brought to the area where the column is located. This is done by the gas company. If you have your own project, it must be approved. And work starts only when you receive the coveted permits.

The rules for installing geysers are as follows:

1. Minimum room volume for installation: 7.5 cubic meters.
2. This room must have ventilation and ceiling heights of at least 2 m.
3. Availability of a chimney with a diameter of 12 cm.
4. The pressure of the pipe carrying water is from 0.1 atm.
5. Installation in bathrooms is prohibited.
6. The equipment is mounted on a wall made of non-flammable materials, at a distance of at least 10 cm from the stove.

Installing a geyser: all the necessary steps

There is no need to rush and buy the speaker model you like. It may simply not fit certain parameters. First you need to complete a number of activities and only then buy.

1. Checking the room where installation is planned for compliance with the placement of the column. The bathroom, and sometimes the kitchen, do not always meet the requirements. The home owner may not know this.
2. Registration of permitting documentation, project preparation. This is done by specialists from the gas office to which the household is assigned.
3. After drawing up a project and obtaining permission, you can purchase a column according to the parameters proposed in the project.
4. Choosing a location. It is already indicated in the project. It is necessary to maintain the parameters. The distance from the floor surface must be at least 1 meter and 50 cm from the opening for the hood and chimney.
5. It is imperative to have a ventilation system next to the column. This is not a chimney, but a special ventilation system.
6. Purchasing the speaker itself. This must be done in specialized stores. A certificate is required. You should not purchase it secondhand or in spontaneous markets. This is dangerous and no one gives any guarantee.
7. Before installing a gas water heater in a private house, you must contact representatives of the gas office and ask them to carry out the installation.
8. Only professionals can install and connect to the chimney efficiently with a guarantee of complete safety.
9. Installation and connection is not difficult. But minor violations can lead to tragedy. Remember that carbon monoxide is odorless and its effects on the human body are fatal. The person simply falls asleep and never wakes up again.
10. Connection to the gas source and start-up is carried out only by professionals, for which a special act will be drawn up, which gives the right to use or prohibits until the violations are eliminated.

Analysis of the most common installation errors

The most common mistake is installing a geyser in the bathroom. As a rule, this room does not have a window. It is especially dangerous to install speakers without a chimney. There are models of water heaters in which carbon monoxide exits through openings, and is removed from the room through a ventilation hole in the wall.

The second most common mistake is the desire to hide the device so that it does not visually stand out from the interior. Often a geyser is installed in a cabinet. This leads to disruption of the proper functioning of the gas water heater.

Even if a distance of 10 cm is maintained from the cabinet walls and there is no bottom bottom, the air flow will still be insufficient to cool the device. It will take longer to cool down, which will significantly shorten its service life.

The third mistake that often occurs is a mixed-up connection of the gas pipe in the column. This leads to water entering the gas pipeline. The liquid gets there through the gas column and then moves down through the pipes. This is how water enters the gas equipment of the neighbors below, completely disabling it.

Liquid removal is carried out by gas services. Once a source is discovered in the owner’s apartment, the gas will be turned off and a fine will be issued. This is what a gas shutoff order looks like

It is impossible to prevent GorGaz workers from performing a shutdown. In case of refusal, the police will be called, as people's lives are at risk.

Geyser in the kitchen

The geyser is still a frequent guest in our apartments

A column or instantaneous water heater is a device that, due to the combustion of gas, warms up flowing water. Gas can either be supplied through pipes or be liquefied from a cylinder. But in practice, only natural gas is used in city apartments. For many old houses, a water heater is the only way to heat water, because the power of the wiring is not designed for the use of boilers.

You can't always see it, but you need a gas water heater

Instantaneous water heaters are often used when planning a small kitchen in Khrushchev and Stalin buildings. Older models are lit with matches, and heating depends on the flow of water. Now they have been replaced by options with electronic control, auto-ignition and electronic temperature control.

In private houses and large country apartments, gas boilers are used instead of water heaters. Their difference is that the boiler has 2 separate circuits - heating and water heating. The column heats only running water.

Advantages

• fast heating of large quantities of water;
• compact dimensions;
• power does not exceed the capabilities of gas lines;
• direct-flow scheme. less heat loss, heats the apartment only when it is running (important in summer), hot water is available immediately as soon as the heater is turned on;
• relative cheapness of use, depending on the price of gas.

Flaws

• explosion and fire hazard;
• requires good traction. otherwise there is a risk of carbon monoxide poisoning;
• you need a chimney and good ventilation, which should be taken into account in the design of a small Khrushchev;

Strict requirements for installation and further operation due to the potential danger of the device.

List of documents according to standards

The list below is approximate and as complete as possible, but it depends on the region. In addition, if the connection is not happening for the first time, some documents may already be in the relevant services or in the hands of the owner of the apartment building/in the housing office. How to make an air duct for a kitchen hood can be read in this article.

So, you will need:

1. A copy of the home or apartment's title deed or similar document proving that you are the owner.
2. Copies of civil passport (pages 2,3 and 5).
3. Copies of the tax payer's certificate (TIN).
4. Permission to process personal data.
5. Gas Buyer's Passport.
6. Your letter about concluding a work contract.
7. Maintenance contract for fire hazardous equipment.
8. Specifications for gas connection issued by the distributor or supplier.
9. Documents on the implementation of specifications (Acceptance certificate for the gas distribution system facility (copy) and others).
10. List of equipment using gas, its characteristics, copies of technical passports.
11. A copy of the deed on the division of property between the owner of the house and the distributor.
12. Copies of passports for the gas meter, additional sensors if available, and certificates of verification.
13. A copy of the gasification project page with the stamp of the Gazprom metrology department.

How to install a gas water heater in an apartment:

Installation of a geyser - technology, standards and connection requirements for houses and apartments

The best option for regular breakthroughs, or for preventive measures related to hot pipelines, is a gas water heater.

If you calculate the financial side of the issue, then this option will turn out to be profitable. After all, gas tariffs are lower than for hot water.

Choice

It is important to take into account a number of technical characteristics of the product. This is a reliable manufacturer that has proven itself in the market from the best side. The equipment must be of high quality, the same as the assembly.

Important! You should only choose appropriate equipment from trusted manufacturers. A prerequisite is compliance with certificate standards.

It is necessary to have a warranty term. In the absence of this, the consequences can be disastrous. Security is of great importance; in the absence of supporting documents, the risk for all family members is quite high.

Characteristics

Before installing a geyser in a house or apartment, you should rely on some technical characteristics. This is about power. The principle of regulating the power indicator is of significant importance. In this case, it is better to give preference to an automatic device.

Gradually, the manual method is losing its former popularity. Now they use an electronic mechanism, in which the robot is carried out using a galvanic component. This element increases the cost of the device, but also improves its use.

It is best to give preference to a closed turbocharged type of exhaust of combustion products. The choice of an atmospheric apparatus is justified only if a private house, for example, is equipped with its own chimney.

Additional functionality includes a draft sensor, a thermocouple, and the presence of a hydraulic valve that minimizes overheating of the device. All these features are a kind of security level.

Recommendations

There is no need to apply special knowledge or effort during the installation of a geyser, as can be seen in the photo. Time costs and difficulties lie elsewhere. This is the collection of documentation that complies with the standards.

To avoid negative consequences, you should know what is needed to install geysers. It is worth pre-designing the location of the device. The plan should be certified and work carried out in accordance with technical supervision standards, the fire service, GorGaz, and the City Administration.

Installation Requirements

During the work process, you should familiarize yourself with the basic requirements for correct installation of the device.

It is necessary to take a plan for the gas pipeline, chimney, and water supply. To do this, you need to contact the Housing Office.

You should plan the installation of the device, taking into account the basic standards. In this case, it is best to seek help from a specialist from GorGaz. This will help minimize the risk of conflict situations arising on this basis. This makes it easier to obtain the relevant documents.

The technical capabilities of the device in the project should be indicated. After this, the housing office checks the data you provided. After this, you need to submit an application to this service for installation permission, and add the necessary plan to this.

Then you need to apply for permission to repair, then replace the pipelines. Then, in order to comply with all standards and permits for the installation of geysers, you must submit an application to check the technical condition of your chimney.

An application is submitted to an organization that monitors ventilation ducts, as well as the chimney itself. You should contact the City Administration to obtain permission to redevelop communications.

If you change the location of the column, the collection of documentation that complies with the necessary standards is aggravated. This procedure will take much longer than replacing old equipment.

Documentation

If you fail to comply with all standards, you will receive fines for illegal installation of a gas water heater. To avoid this, you need to collect a number of documents and prepare properly:

• You must have the technical passport of the device with you;
• An application for reorganization is required. This application must be certified by the City Administration;
• You should have with you an approved project for installing the device;
• You must have a certified document that confirms the appropriate condition of your chimney.

Installation algorithm

Installation of a geyser must be carried out by specialists

Documentation is regulated by the law on gas supply to the population. The list differs depending on whether you are changing only the model, device and location, or if you are installing the equipment for the first time.

The model is changing

The column becomes outdated over time and can be modernized by replacing it with a more modern one

• Buy a certified gas heater. which is allowed to be installed.
• Take from the housing office certified copies of the gas and water supply system diagrams with the equipment installation location clearly marked.
• Then submit an application for replacement, subject to maintaining the installation location, to the gas service. there are also applications for the repair of water and gas mains on the site.
• The gas service will do the work, and it will issue a certificate of commissioning of equipment and compliance with the requirements.

Changing the device and installation location

How to install a gas water heater video master class:

• You will need to change the gas supply, water supply, and air venting.
• Come to the fire department to pick up a chimney condition report.
• Order a transfer project from GORGAZ or a private certified organization and receive it.
• An apartment building will require permission for redevelopment from the city administration.
• You must have in your hands an act, a project, a permit, a technical passport of the boiler or water heater, a document on the ownership of the apartment. With these documents and the application, contact the gas service again.
• Specialists will install and connect the equipment and conduct the first start-up. Then they will seal the meter and issue a Certificate of Commissioning.
• At the end, you should have in your hands certificates that confirm safety from the fire inspection, technical supervision, and commissioning. Information about the transfer is additionally submitted to the BTI.

First installation

To install a geyser you need to collect quite a lot of documents

If gas is not supplied to the house, you will need to build a gas supply line. This is an expensive process, and many owners of private houses prefer to make do with solid fuel boilers. For multi-apartment buildings, gas supply is carried out by the developer, the housing office, or contributed by the owners together.

In a small kitchen, placing a speaker is a little problematic, since every centimeter counts

• Obtaining documentation includes consent to supply gas from distributors and transporters, calculation of consumption, obtaining technical conditions, permission for land allocation for the gas pipeline.
• Design consists of concluding a project agreement, collecting and examining documentation, and approval by the authorities listed in the previous paragraph.
• Construction consists of construction and installation work and commissioning.
• At the end, a gas supply agreement is concluded with GORGAZ or OBLGAZ.

Water connection

Now a pipe with cold water is connected to the column, and hot water is distributed throughout the house. It is better to connect to the water heater using an American connection with a movable union nut.

For cold and hot water lines, be sure to install shut-off valves - ball valves.

If there is no cleaning filter at the main inlet to the apartment or house, then a coarse filter of 80-100 microns is installed in front of the column. It is also advisable to install a fine filter of 10-20 microns.

The cleaner the water, the longer the heat exchanger will work without blockages and scale.

Pipes are supplied in one of the following options:

• Supplying pipes to a distance of less than 30 cm to the column and connecting using a flexible hose or copper/brass tube;
• Direct connection of metal-plastic, polypropylene or steel pipes, depending on the material used for the main wiring.

To tap into a cold water pipe, you will need a tee. The simplest option is to insert into plastic using clamp fittings. All you need is an adjustable wrench, a pipe cutter and a flaring tool. The fittings you will need are a tee, an American fitting and a shut-off valve.

Water connection diagram

Having previously cut the pipe in the right place so that the supply to the column is as smooth as possible and without additional elbows, American fittings are inserted into the cut and a tee is screwed to them. Next, a section of pipe is connected to the column.

For steel pipes, you will need a welding machine and welding skills. Instead, a special tee clamp is used. It is fixed to the pipe and then a hole is drilled through the outlet in the cold water pipe. Next, a section of pipe is connected to the column.

For polypropylene pipes you cannot do without a soldering iron. It is easy to rent, but the amount of work will be less than with steel pipes.

Next, the DHW pipes are laid out, if they do not already exist. A pipe with a shut-off valve is led from the column, and then to each mixer in the house.

If you are only replacing the column, then it is still advisable to re-lay the pipes to avoid the accumulation of adapters and elbows in front of the gas column. This will protect the equipment from unnecessary turbulent flows in the pipes, which can affect the operation of the hydrothermal control unit.

Specifics of gas supply installation

The pipes in the apartment are the property of its owner, but unauthorized changes to the gas supply system cannot be made. For any changes, you must obtain permission from the gas service, otherwise a fine will be issued.

If the gas water heater has already been installed in this place, then this will not cause significant changes to the project. It is enough to turn off the gas valve on the pipe and replace it. If you are installing a water heater for the first time, you will need to do some wiring.

The diagram shows how to properly route gas and water pipes. Depending on the material of the pipes, you will need tools for welding metal or soldering plastic (+)

When installing pipes yourself, you must follow the following rules:

1. Turn off the gas before starting work.
2. Carry out work with an open window.
3. Remove debris from pipes that may have arisen during installation.
4. Do not route pipes through door and window openings.
5. Do not use the ventilation shaft for laying pipes.
6. Do not install the gas pipeline into the wall.
7. Do not use flexible hoses longer than 3 meters.
8. Paint metal pipes.

Particular attention should be paid to sealing the connecting elements of the gas pipeline. To do this you need to use a sealant and sealant. After completing the wiring, you can begin installing the device.

Installation of equipment

The sequence of actions when installing a column usually looks like this:

Markings are applied to the wall: holes will be made along it. The column should be located at a sufficient distance from the stove and at such a height that the viewing window is exactly at the user’s eye level. The length of the vertical section of the chimney extending from the column must be 500 mm or more if the ceiling height is 2 meters or more, and not less than 250 mm if the distance from the ceiling to the floor is equal to or greater than 2.7 meters. You should also take into account the requirements of the standards discussed above. Having drilled the holes, insert the dowel sleeves into them, and then screw in the mounting hooks onto which the column is hung. A tee with a ball valve and a filter is cut into the cold water pipeline, which is connected by a pipe or hose to the inlet fitting of the water circuit of the column. With a collector circuit, the pipe is laid from the collector pipe, and a ball valve and filter are installed on it

Please note that the inlet and outlet fittings are not equivalent - it is important to identify the inlet one. If a steel pipe is used for connection, the threaded connections must be sealed with tow, flax, FUM tape or Tangit Unilok thread.

When using a hose (flexible line), there is no need to use a sealant - the tip of this element is already equipped with a gasket. In a similar way, a pipe for distributing hot water is connected to the outlet fitting. Next, you should smoothly open the root valve on the cold water pipeline. In this case, you need to monitor whether leaks appear at the joints. If it appears, you need to tighten the nuts (for the flexible line) or add a sealant. The gas fitting of the column and the tap on the gas supply line are connected by a hose, which must be clamped with clamps. The tightness of the connections is checked using soap foam - if there are leaks, it begins to bubble.

All that remains is to secure the pipe to the smoke exhaust pipe and install the draft sensor according to the instructions. The second end of the pipe is inserted into the chimney channel using a special adapter. Now you can carry out a test run.

The process of dismantling old equipment

Before dismantling old speakers, you should prepare suitable tools and materials for this. These include an electric drill, wrenches (open-end and adjustable), fasteners, fittings and taps, hose, tape and sealant.

In the same list there is a pipe for water supply. Its diameter is usually indicated by the instructions for the device. You should also prepare filters, tools for soldering and cutting plastic communications, Mayevsky taps and a corrugated pipe, which should match the size of the boiler inlet.

To remove the equipment, perform the following steps:

1. Close the valve on the hose that leads from the gas pipeline to the old column;
2. Remove the hose securing nut. You can avoid damage to the pipe by securing it with a wrench;
3. Separate the hose from the equipment;
4. Close the valve on the supply water supply.

The next stage of dismantling involves disconnecting the heater from the chimney. Now it is enough to remove the device from the fastener mounted on the wall. After this they move on to installation.

Rules and regulations for installing a geyser

Installation of gas water heaters (dispensers) is regulated by the norms and rules set out in SNiP 42-01-2002. According to the recommendations set out in this document, boilers are connected to low pressure gas pipelines (0.3 MPa).

Standards for installing a geyser

Therefore, connecting the dispenser begins with drawing up a project for the “internal” gas pipeline. Without such a project, no management company will undertake the installation of a new water dispenser. After all, the column needs not only a gas pipe, it also needs an exhaust hood - a channel for removing combustion products or unburned “fuel”. And all the installation details, including recommendations regarding the dimensions of the exhaust duct, will be displayed only in the design documentation.

Well, if a water heater is not provided for in the gasification project, then the necessary changes are simply made to the documentation - a diagram of the installation of a gas water heater is drawn on the drawings. And if such a scheme is already present in the design documentation, then the apartment owner can look for a master who is ready to take on this work.

Moreover, all manipulations with the project concern only the owners of new speakers installed in the apartment for the first time. Replacing an existing gas heater does not require any approval from regulatory authorities: after all, this source of consumption is already included in the home gasification project.

However, most modern kitchens fit the regulated standards for installing a geyser (according to today’s SNiP, water heaters are installed only in this functional area).

After all, premises suitable for installing speakers must meet fairly modest requirements, namely:

• The kitchen area must exceed 7.5 square meters.
• The ceiling height cannot be less than 2 meters.
• The dimensions of the receiving channel for the “chimney” must correspond to a circle with a diameter of 120 millimeters. A standard exhaust vent is suitable for these conditions.
• The supporting surface of the column (kitchen wall) must be constructed of non-combustible materials.

Responsibility for unauthorized installation

If the insertion into the pipe for connecting the column is made bypassing the metering device, then such an act falls under Art. 7.19 AC RF. For this, administrative liability is provided in the form of penalties.

For individuals, fines range from one and a half to two thousand rubles. This is the least possible measure for those illegally connected to the gas system. How an official connection to a centralized gas main is made is described in detail in the following article, which we recommend that you read.

In addition to the administrative code, unauthorized tapping and installation of gas equipment is subject to Federal Law No. 69 “On Fire Safety.” According to the text of the document, the owner of the property bears administrative or criminal liability depending on the severity of the consequences.

If the actions cause property damage to third parties, the owner will be obliged to compensate it in full. In addition, a fine of RUR 80,000 may be imposed for a violation. If significant harm was caused to the health of neighbors, the owner may be taken into custody and imprisoned for up to two years.

Requirements for ventilation and chimney

To create air circulation in the room, a ventilation hole is necessary. It should not be clogged, air should pass through it calmly. If you neglect this rule, then in the event of a gas leak, the residents of the apartment will receive poisoning with serious consequences.

The risk of household gas detonation will increase significantly if it is not removed naturally, since a leak can occur at night, when a person is not able to detect it.

For the normal functioning of the gas water heater, an additional chimney must be installed. It can be brought into the common house system or directly onto the street. When constructing a chimney, it must be taken into account that it cannot have more than two bends at an angle of 90 degrees.

The total length of the chimney should not exceed three meters. Three options for the location of the chimney pipe are allowed.

The pipe must have a vertical section at the point of connection to the water heater. The length of the vertical section must be greater than or equal to 50 cm. The length of the horizontal section of the pipe should not exceed two meters.

It is possible to make a chimney from a flexible corrugated pipe, but it is necessary to prevent its sagging, which can block the removal of combustion products.

If the installation of the column does not involve a chimney, then you cannot limit yourself to a ventilation hole in the wall. It is necessary to install a full-fledged hood, but even in this case, the gas service will have questions about such a carbon monoxide removal system.

Checking the tightness of gas channels

After installing the water heater, you need to check the gas pipes for leaks. If you have a gas analyzer, this greatly simplifies the procedure and improves the quality of the test. If this device is missing, then you can use the old method.

To do this you will need regular soap, a jar and a brush. The soap is dissolved in the jar to form a liquid emulsion. Next, using a brush, the emulsion is applied sequentially to the pipe joints. As you apply, you need to monitor the appearance of bubbles in the treated areas. If they appear, the leak must be eliminated.

Before testing for leaks, you must take the necessary safety precautions. Be sure to turn off all electrical appliances

Under no circumstances should you check for gas leaks using fire. This is dangerous and may cause an explosion. There is no point in risking your life and the lives of your neighbors.

Gas equipment requires regular inspection and periodic cleaning. You can clean the dispenser yourself, but if you have no experience at all in servicing such systems, it is better to contact a company that has entered into an agreement with you for the supply of gaseous fuel and maintenance of the devices involved.

Column layout rules

The water heater cannot be located on a load-bearing wall of the building. This is directly prohibited by the requirements for the installation of geysers. In the event of an explosion, this may result in damage to the building or its partial destruction.

To clarify the possibility of installing the device, you need to take information from the cadastral passport of the apartment and the general plan of the house. This information can be clarified by calling specialists.

There are requirements for the space from the column itself to the opposite wall. The distance should not be less than one meter. This is necessary for free access to the device for its maintenance and inspection. It is also forbidden to install gas supply pipes into the walls.

This makes it difficult to inspect communications and find gas leaks in the apartment. If this violation is detected, an order to eliminate it will be issued and information will be provided on how to correctly install the gas water heater and where to contact.

The column must be located at a distance of more than 10 cm from the wall. It is not allowed to install a gas water heater on a wooden wall without prior preparation. A steel plate must be installed at the installation site, equal to or larger in area than the back wall of the device.

It is not allowed to install a column above a gas stove. These devices must be at least 1 meter apart from each other. Also, you cannot use the hood for a gas stove as a exhaust outlet for combustion products. You cannot use one chimney for the hood and gas water heater. This is expressly prohibited by safety regulations.

Installation of a chimney in an apartment with wooden walls

In wooden houses, the use of a blue fuel water heater is allowed, but fire safety standards for installing a gas water heater must be observed. The chimney cannot come into contact with wood; non-combustible material must be placed between them.

Basalt or mineral wool can be used as thermal insulation. It is allowed to use heat-resistant polyurethane foam.

This is necessary to prevent fire in the event of strong heating of the chimney. As a rule, old wooden houses do not have chimneys, or they are intended for stove heating. It is prohibited to install gas equipment in unsafe houses.

Electric water heating storage device

In a storage water heater (boiler), water is heated to 35-38ºС and then its temperature is maintained at this level automatically. When you open the tap, warm water flows out of the container, and instead the next portion of cold water enters the tank. The duration of water heating in these water heaters depends on two parameters. This is the volume of the tank and the power of the heating element. To keep energy losses to a minimum, water tanks are made heat-insulating (in the form of a thermos), which does not allow the heat of the water to be transferred to heat the room where the water heater is installed.

Typical storage electric water heater device

Such a device can be connected to a regular outlet, since it does not require high power to gradually heat the water. For example, 150-liter water heaters of this type consume no more than 2 kilowatts. It is this circumstance that makes these devices popular, since they can be installed in almost any room. In addition, the high demand for them is due to another advantage of storage water heaters: water can be consumed from two water intake points simultaneously - both in the kitchen and in the bathroom.

On the other hand, boilers also have some disadvantages. These are large in size and require periodic maintenance: cleaning the heating elements from scale, replacing the magnesium anode. It is no secret that any heating element becomes covered with scale during operation, which reduces its heat transfer, and, consequently, the energy consumption for heating water increases. To protect the heating element from scale, a magnesium anode in the form of a rod is built near it. Dissolving during operation, it reduces the formation of scale. As it wears out, and this depends on the intensity of use and the level of water hardness, the anode is changed. The volume of heated water depends on the capacity of the tank, so when choosing a storage water heater, you need to focus on the capacity you need.

A tank that is too large will consume more electricity, and it will take up extra space. Therefore, you should think carefully to choose a device with the optimal capacity for you, without spending extra money and not taking up extra space. If the water heater is needed only to supply warm water in case of periodic outages, a volume of 10-15 liters will be sufficient. Only for taking a shower will a device with a tank capacity of 50 liters be sufficient. For a hot bath you will need a tank with a capacity of up to 150 liters. In a country house where there is no centralized hot water supply, the required volume is 200 liters or more.

Most manufacturers produce horizontal and vertical models; recently, modern universal designs have been created (installed as needed - either horizontally or vertically).

Types of heaters and boilers for apartments (including Khrushchev)

If we talk about gas heaters, they can be flow-through or storage. But in Russia, gas boilers are not widely used, because they are less convenient, cost more and take up a lot of space. They should only be installed if the gas supply is too weak. Mostly they install instantaneous gas heaters. You can find out how many sockets you need in the kitchen here.

Modern models may have a closed or open combustion chamber. Open ones are a little safer and require less paperwork during installation. They are needed if there is no chimney in the house. The latter are suitable if the old heater is being replaced with a new one, the chimney and gas supply have already been made and tested.

Suppliers offer 3 types of power. 17-20 kW is needed for a one-room apartment with 1 inhabitant. If a person takes a shower, there is no longer enough power to wash dishes. Devices with a power of 20-26 kW are indispensable for apartments. They provide 15 liters of water per minute at a temperature of 40 degrees. The power of an average heater is enough for a family of 4 people and an apartment with 1 shower and 2 sinks. A power of 26-28 kW is suitable for two-level apartments or houses. You can find out what kitchen hoods there are by following this link.

Tip #3: Follow the instructions carefully during the installation process.

Let me remind you once again that although installing geysers is quite feasible on your own, do not forget that you are dealing with gas, so any amateur activities should be excluded.

The instructions begin with preparing all the necessary equipment that will be needed to successfully complete the plan:

PVC pipes for water and gas differ in marking color

Fixing the unit on the wall

Before installing a gas heater in a private house, be sure to arrange a chimney opening above its location. The ventilation outlet can be made into the wall or the ceiling, whichever is more convenient for you.

Next we proceed as follows:

1. The mounting holes are clearly visible from the back of the device. We measure them and transfer the obtained data to the wall;

1. We insert a drill with a Pobedit tip into the nose of the hammer drill and drill holes in the marked places;

Drilling a concrete wall using a hammer drill

1. Now we tighten the screws, in some cases these may be hooks, and hang the gas water heater on them with our own hands.

As you can see, so far everything is as easy as if you needed to hang a shelf or a picture. But it’s too early to relax; now something will be a little more difficult.

Connection

And now the device is already hanging in front of you, what next?

1. We cut out a piece of corrugated pipe of the appropriate length and connect the outlet of the column to the chimney outlet. As a rule, the corrugation comes complete with the gas equipment itself, so there should be no complications on this side;

1. We turn off the gas supply, cut the gas pipe, if we are talking about a metal product, you will need a grinder, cut the thread and screw on the tee, having previously wrapped the thread with a special fum tape to enhance the seal;

Installed tee on a gas pipeline

1. To the tee we connect the second end of the pipeline and a plastic outlet leading to the corresponding hole on the device being installed, which is very convenient to do using a pipe soldering iron. Also, do not forget to use fum tape, and fasten the hose itself with clips to the wall so that it does not dangle in the canopy;
2. Now we turn off the water supply, after which we cut in a tee in the same way as with the gas pipeline. Only in this case, before branching, we also install salt and magnetic filters. This way you will significantly extend the service life of the water heater;
3. We connect a hose leading to the mixer to the outlet of the column.

Example of a completed connection

By the way, if you are just replacing old equipment with new equipment, then all the tees are already installed, and the task is simplified to simply connecting pipes or hoses.

Testing

The first start of the gas water heater is a kind of assessment of the work you have done, so it should also be done correctly:

1. We mix a soap solution with which we coat all the joints of the gas pipeline;
2. We turn on the gas supply and very carefully inspect the threaded connections for the possibility of bubbles;
3. If gas leakage is noticed somewhere, then it is necessary to immediately shut off the gas pipeline and redo the connection. If everything is fine, then open the water supply;
4. We wait a while for the liquid to pass through the filters and open the hot tap. Next, you should hear the click of the piezo, unless, of course, you forgot to install the batteries, after which the burner will light up and the desired liquid will flow from the mixer.

That's it, you can take a bath, wash dishes and hands, well, in general, exploit the fruits of your labor.

How much does it cost to install a geyser? Dismantling and replacing a geyser by the hands of specialists will cost an average of 3,000 to 4,500 rubles. This is in Moscow, in the regions it will be cheaper. The amount is not astronomical, but, nevertheless, it is still a pity to give it for work that you can easily do yourself. And everything would be fine, but in this matter there are a great many nuances, ignoring which can greatly hit the user’s pocket.

What are these nuances? What kind of rules and regulations generally govern these types of work? And you simply must know the basic provisions, because this is not a plumbing system with which you can experiment. Gas is gas, negligence and carelessness in dealing with it ends very badly. In this article we will look at the procedure for replacing and installing a gas water heater. Let's look at step by step how and what you can do yourself, and what is best left to a gas industry representative.

Standards and requirements governing the installation of a geyser

Note! Let’s immediately make a reservation that all types of work related to gas supply, i.e. supplying a gas pipe, installing tees, shut-off valves on the gas pipe, etc. carried out only by organizations that have the appropriate special license. Ignoring this provision will, at best, lead to a hefty fine and a severe headache.

All work on installing a geyser can be divided into two categories:

• installation from scratch, i.e. it wasn’t there, but you decided to put it in;
• replacing the old column with a new one.

In the first case, a design and supply of a gas pipe to the location of the future water heater is required. All this work is the responsibility of the gas industry in your area or a company that has a license for the corresponding type of activity. It is impossible to do without this. In this case, do not try to do anything yourself. This is not smart, because... You yourself risk your life and property, and when installing a gas water heater in an apartment, you endanger other people. And it’s not easy to play such games with the state, it’s not the right weight category. Therefore, entrust this work to people authorized by law for this type of activity.

If the project is ready, everything is agreed, then by completing part of the work properly you can save a significant amount. Any work that you decide to carry out yourself must be carried out strictly in accordance with the requirements of the approved project; if this is not done, the gas industry will not accept this gas water heater for operation.

Note. All work on the installation of gas units begins only when you receive a project with all the necessary permits and approvals.

All standards for installing a geyser are regulated by the following acts:

— SP 42-101-2003 “General provisions for the design and construction of gas distribution systems made of metal and polyethylene pipes”

— SNiP 42-01-2002 GAS DISTRIBUTION SYSTEMS

​

In order to bore the reader with many clever words, we present the basic standards for installing a gas water heater, which apply to the intended installation location:

1. The room in which the column is installed must have a volume of at least 7.5 m3.
2. The room must have ventilation (vent, window, etc.).
3. The ceiling height in such a room must be at least 2 m.
4. The room must have a chimney with a diameter of at least 120 mm (at the same time, “smotherers” in apartments do not qualify as such).
5. The pressure in the water supply must be at least 0.1 atmosphere.
6. It is prohibited to install geysers in bathrooms.
7. The column is installed on a wall made of non-combustible materials; installation above a gas stove and at a distance closer than 10 cm to it is prohibited.

At the same time, those speakers that are installed in bathrooms, in accordance with the technical standards in force at the time of installation, are allowed to be used in the future. That is, the law does not clearly prohibit its further exploitation. This means that replacement with a new one does not prohibit. And does not require transfer at the user's expense.

If all these requirements for installing a geyser are feasible, then you can order a project. The exact installation location and other details will be displayed in the project.

Removing the old column

Since the basic requirements and standards have been reviewed in general terms, if everything complies, you can begin replacing the gas water heater. And we should start with dismantling. You can do this yourself and save from 300 to 800 rubles.

We start by shutting off gas access to the column by closing the tap at the end of the gas pipe. Using an adjustable wrench or an open-end wrench of the appropriate size, unscrew the fixing nut of the hose (rarely, but there is a method of supplying gas using a metal pipe). It is quite difficult to damage the gas pipe when unscrewing the hose, but with the “ancient” connection method, i.e. a piece of metal pipe, quite realistic. Especially if the joint has been painted over for years. In this case, do not use excessive force; to remove paint, use a modern solvent specifically for this work. When unscrewing, hold the gas pipe with a second adjustable wrench, this way there is less chance of damage.

After disconnecting from the gas pipe, it is necessary to remove the hose (pipe) from the point of entry into the column. If the hose has recently been changed and its condition is satisfactory, then it can be reused when connecting a new column. If you have any doubts about the reliability of the hose, purchase a new one. When purchasing, take a certified and tested hose; after all, this is gas and buying a cheap hose from an unknown manufacturer is not appropriate here.

The next dismantling step is to turn off the water supply system. If there are taps to turn off the column, turn them off. If this is not possible, shut off the supply to the apartment. In the case of the latter option, before installing a new column, purchase two taps for the inlet and outlet of water from the column and install them on the pipes in the place where the connection will be made. This will make it easier to maintain in the future.

After disconnecting the column from the water supply, remove the connecting pipe from the outlet of the column and remove it from the chimney. The speaker is disabled and can now be removed from the wall mount. The installation site is free, you can begin installing the new unit.

Installation and commissioning of a gas water heater

During the initial installation, it is better to entrust the connection and verification, with the registration certificate of the gas water heater, to gas specialists. If you change the old column, you can do all the work yourself. But there are two nuances, if you doubt your ability to correctly install a gas water heater - trust the specialists, your wallet will be somewhat thinner - but the nervous system will remain unaffected and, ultimately, the benefit will be yours.

If you decide to do everything yourself, you will succeed, the main thing is to do everything slowly and progressively. But even in this case, you cannot do without a representative of the gas industry; he must register the dispenser. The best option, perhaps, is the situation when you do all the connection work yourself, with the exception of gas-related work. In this case, you will save a significant amount and there should be no problems with the gas service, because connection to the gas main will be carried out by their representative. We will consider this option.

Tools and materials

Before starting work, you must purchase and have the following materials:

• Galvanized pipe or corrugation, no thinner than 1 mm. If it comes with a speaker, great. If not, measure the diameter of the outlet of the column boiler or look in the instructions and purchase the appropriate pipe.
• Purchase a ring-socket for arranging the entrance to the chimney, also according to the size of the corrugation.
• If you plan to install a gas water heater in your house and you need chimney equipment, you will need an asbestos or metal pipe with a diameter of at least 120 mm, or more. The length is at least 2 meters, more is possible - the traction will be better.

• The gas hose is standard, the size of the hose will depend on your conditions, i.e. distance from the end of the gas pipe to the inlet into the column. Pay attention to the type of thread at the inlet to the column, the hose tip must be suitable, there must be a match in the type of thread external/internal and a diameter of ½" or ¾". The diameter of the fixing nut on the hose is ½" and if the inlet to the column is ¾" you will need an adapter (coupling).

• It is better to prepare the water supply connection point in advance, so you only need two connecting hoses of the required length. You can make connections using metal-plastic pipes, whichever is more convenient for you. In the latter case, determine whether couplings are needed to match the dimensions of the pipe and the connection location and thread (external/internal).
• Dowels for mounting the speaker on the wall.
• If your home does not have a coarse filter installed, we recommend installing one. The service life of the new unit will directly depend on the quality of the water.

Tools you will need:

• Depending on the complexity of the work and the material - a hammer drill with a set of drills and chisels, a drill with a drill for ceramic tiles.
• Adjustable wrench (2 pcs.).
• Open-end wrenches 27/30 and 32/36.
• Tow and sealant type "Unipak".

Installation and testing of a new unit

This description assumes that the water supply and the presence of a chimney have already been implemented. At the location where the gas water heater is installed, mark the points for installing the fasteners. You must calculate the height of the water heater so that the connecting pipe (corrugation) has a vertical length from the outlet of the water heater to the outlet of at least 50 cm, if the height of the room exceeds 2.7 m - 25 cm. At the same time, the installation height of the gas water heater is not should give children free access to the device. Also measure the distance between the mounting holes on the speaker body. After you calculate the installation locations for the dowels using a hammer drill or drill, depending on your conditions, make holes and install hooks. The speaker can be hung on the wall.

Now, using connecting hoses or PVC pipes, we connect the water supply to the inlet and outlet of the column. Using a hose is convenient because it does not require tow or FUM tape at the joints. We connect the cold water tap in series with the gas water heater inlet, indicated in blue. In the same way, we connect the hot water outlet to the tap (indicated in red). We open the cold and hot water tap and see if everything is sealed. If a leak is detected, carefully tighten the hose fixing nuts. Without unnecessary efforts, as you can crush the rubber gasket - seal. The connection using pipes will need to be unscrewed in places of leakage and the tow with a sealant or FUM tape must be twisted.

After we achieve the tightness of the water supply, you can go in two ways: either call a gas technician, or install the gas water heater yourself in full. You decide.

If the second option, then take a gas hose and screw it to the gas tap. After this, connect the other end of the hose to the inlet in the column. We clamp without unnecessary effort, so as not to crush the paranitic gaskets. We take a soap solution, generously smear the joints around the entire perimeter, open the gas supply tap and carefully observe to see if there are any bubbles. If there is, press the nut a little and apply it again. So until we achieve complete tightness.

So, we have a sealed connection between water supply and gas. The next step is to install the corrugation. Here everything is much simpler, on the one hand we put the speakers on the outlet, on the other we insert them into the chimney socket.

We insert the batteries into the column, open the hot water tap and adjust the water temperature according to the operating instructions for the column. We use it.

And one last thing. Usually, large stores also have a connection service. When purchasing, ask how much it will cost to connect them to a specialist. It will be cheaper or even free, and there will be no issues with the warranty on the column at all. And registration in the gas industry will take place without unnecessary friction.

If this is not available, I still recommend that you entrust the connection of the gas hose to a gas installer (the cost of installing a gas water heater for such a connection is several times less than for complete dismantling and installation), and he will be pleased (he will earn money) and there will be no complaints against you. Plus a guarantee of safety and integrity. But it is, of course, up to you to decide.

Components of a chimney

• An umbrella (protective cone) is the upper element of the chimney.
• The chimney is the next part of the structure after the protective cone. There is a version with or without a thermal insulation layer.
• Pass-through pipe - necessary to isolate the previous element from the wall of the house.
• Brackets - necessary to secure the chimney.
• Clamps - connect pipe joints.
• Tee - necessary for the transition from the gas water heater to the chimney.
• Inspection window - allows you to monitor the condition of the chimney pipe.
• A collector of condensate that accumulates as a result of the operation of the chimney.

Operating rules

In order for the new column to serve for a long time and not require repairs, you need to:

• Carry out regular maintenance, cleaning the device from carbon deposits, dust and scale. The recommended frequency is once a year, but if it gets dirty, unscheduled cleaning can be done.
• Avoid excessive heating of the water in the column, as this accelerates the process of scale formation on the walls of the heat exchanger.
• If necessary, install a filter and pump in front of the column.

You can see an example of installing a gas water heater in the following video of the “Yury Trifonov” channel.
