How to turn on and ignite gas boilers of the Danko and Conord models

Basic faults

The design of Conord boilers is very simple and does not have many details.
This can significantly reduce the number of weak points in the design and reduce the number of malfunctions. The heat exchanger and ignition equipment are usually considered to be the most loaded and most likely to fail. The heat exchanger is susceptible to lime deposits. The additional layer isolates the coolant from the walls, reducing heating efficiency.

It is necessary to increase the combustion mode, which increases the load on the external part of the heat exchanger, which fails faster. The ignition equipment fails due to thermocouple failure or other reasons.

There is also a constant danger of burner nozzles becoming clogged with soot, which can be eliminated by periodically cleaning the boiler.

Kinds

Danko gas boilers are produced in various structural types, which can be divided into groups according to general characteristics.

By type of installation:

• Floor-standing. Installed on a special non-flammable stand or directly on the floor.
• Wall-mounted. Wall-mounted installation, on load-bearing walls or special metal support structures (Ramps).
• Parapet. These are non-volatile units with a hinged installation type. They differ from wall-mounted ones in some features of connection to the chimney and the need to ensure a slope of the heating system pipelines, ensuring natural circulation of the coolant.

By set of functions:

• Single-circuit. Designed exclusively for heating the coolant and supplying it to the heating circuit.
• Dual-circuit. Capable of simultaneously heating the coolant and preparing hot water for domestic needs.

By type of combustion chamber:

• Open (atmospheric). Air intake for normal combustion is carried out directly from the room in which the boiler is installed. Smoke is removed naturally using a stove-type draft.
• Closed (turbocharged). Air intake and smoke removal are performed using a turbocharger fan.

IMPORTANT!

Turbocharged boilers are much more stable in operation and are not subject to frequent flame extinguishing due to drafts or gusts of wind.

In addition, there are models with a steel or cast iron heat exchanger.

Also, in some series of units, different types of automatic control of the operation of the gas unit can be used:

• Kare (Poland). Manufactured specifically for installation in Danko boilers. The kit includes a reducer, valves, a thermostat and pressure, draft and boiling sensors.
• Honeywell (USA). High-quality electromechanical gas supply control units, which are installed in the most advanced models of gas boilers.
• Sit (Italy). Automatic control units for gas equipment, used in most European models of gas boilers.

The range of Danko boilers is wide; the user has the opportunity to choose the best option for any area and operating conditions.

Important Operating Instructions

In terms of operation, gas boilers with a closed combustion chamber are considered safer. Their firebox does not communicate with the room air. However, the power of such boilers is significantly inferior to the power of boilers with an open combustion chamber. Therefore, in private households a second type of boiler is often installed.

The choice of future coolant depends on the goals and operating conditions of the system. If the boiler is expected to be turned off frequently, then it makes sense to think about using antifreeze

The operation of such boilers requires compliance with safety precautions. So, to install a powerful floor-standing boiler, it is customary to use a separate room with a certain size. The boiler is mounted at some distance from the walls. Nearby walls should be protected with fire-resistant material to prevent fire.

A ventilation system must be installed in the boiler room. There should also be a source of natural light. The width of the entrance door must be at least 80 centimeters. The chimney is laid in accordance with the instructions for the boiler and from heat-resistant material. The chimney must rise above the roof ridge by at least half a meter.

One safety measure is to install carbon monoxide detectors. The gas detector will promptly detect the leak of a volatile toxin and warn users about it. It can also be configured so that the ventilation is automatically turned on and the gas supply is turned off. Modern automation allows the implementation of a variety of smart systems.

If the temperature, pressure or gas sensor fails, you must immediately turn off the boiler and call a service technician. Using a boiler without these devices is fraught with serious negative consequences.

SNiP requirements state that a gas boiler must be connected to the main line using a copper pipe or a bellows hose. In this case, a faucet must be installed

If signs of a gas leak are detected, you must immediately turn off the gas tap and open the windows to ventilate the room. Do not turn on the light and try to illuminate the room by lighting matches or a lighter.

The gas boiler must be serviced at intervals specified by the manufacturer. Information about the necessary procedures is indicated in the instructions for the device. For example, you need to clean the chimney, remove scale from the heat exchanger, or clear the fumes from the burner. Then the boiler will last a long time, and the risk of serious malfunctions will be significantly reduced.

When using a gas device, do not turn it on at maximum power for a long time. This may result in the release of steam, which is unacceptable.

Sometimes the boiler begins to make unusual noises and vibrations. This may be due to the operation of the fan. We warn you that all actions that require disassembling the boiler casing automatically deprive the owner of the right to warranty repair or replacement.

However, the owner of the unit needs to monitor the operation of mechanisms and systems that protect the boiler from fire. It is necessary to maintain the temperature in the circuits at around 50 degrees, which significantly reduces the likelihood of mineral deposits forming on the internal surfaces of pipes and devices.

Care tips and advice

Proper maintenance of the boiler, performed regularly, will help keep it in working condition for a long time and avoid various accidents and accidents. Otherwise, the unit may break even in the first year of operation. Performing several operations will prevent this from happening:

• even during normal operation of the boiler, you need to contact one of the organizations carrying out work in this area, so that a technician inspects the device for gas and water leaks, the condition of the sensors and chimney, and, if necessary, carries out repair work;
• You should always monitor the water pressure inside or at the outlet of the system. If it drops below 0.8 bar, then water needs to be added;
• The addition of water to the system is usually carried out directly through the boiler, where there is a special tap. In this case, the pressure of the added water must be greater than the pressure of water from the boiler. The supplemented water should only be cold (up to 35°C).

For your information! To spend winter evenings warm and comfortable, you need to properly care for your boiler and also know how to light it.

Depending on the model and manufacturer, this process will be slightly different due to differences in design. This can be clarified in the instructions supplied with the device.

Filling the heating system with water

Starting a gas boiler begins with filling the heating system with water. Everything is simple here - modern double-circuit boilers do not require the installation of a special system feeding unit. It is already built into the boiler and equipped with a special tap, which, as a rule, is located at the bottom of the boiler in close proximity to the cold water connection pipe. Open the feed tap and slowly fill the system with water.

Starting the boiler - how to fill the system with water

A very important point in the operation of any boiler equipment is fluid pressure. To control this parameter of the heating system, almost all boilers are equipped with a pressure gauge. During the process of filling systems with water, it is necessary to monitor the pressure and after it reaches 1.5-2 atm, filling the system will need to be stopped. In principle, the operating pressure of a boiler may vary depending on the manufacturer and model - therefore, see the instructions for the boiler for the exact operating pressure.

Do-it-yourself first start-up of a gas boiler

About the manufacturer

The owner of the Danko brand is the Ukrainian company PJSC Agroresurs, which simultaneously produces heating equipment with several items. Danko boilers are manufactured using imported equipment from Japan, Finland and Denmark. This has significantly improved the performance quality of manufactured products, making them more reliable and durable.

In the production process of boiler equipment, modern assembly and metalworking machines and a powder coating line are used.

The vast majority of technological operations are automated. All boiler units have high efficiency - over 88%. The assortment set includes modifications with a cast iron heat exchanger, the service life of which is more than 25 years.

The advantages of such units include the availability of spare parts on the market, low cost of the kit and reliability.

However, the unit also has disadvantages. Buyers complain about the low level of assembly. Cheap kits are not equipped with modern automatic systems.

The assemblers note the relatively complex processes of assembly and piping with the in-house heating system, as well as increased background noise when the boiler is on, compared to Western analogues. According to responses on the Internet, Danko’s double-circuit options, with a high level of hot water supply, do not always provide the required heating rate.

The organization TD Finist LLC in Taganrog is the official representative of the company; boiler models can be found on Danko.rf. The following heating boilers are sold in Russia: “Danko”, “Danko-Breeze”, “OK”, which are certified according to Russian standards.

You can download factory instructions and boiler wiring diagrams, and get consultations with leading company managers.

Heating boilers Conord

Rostovsky has a rich history and equally rich experience. Initially, the company was engaged in the repair of road equipment, but in the early 70s it was reoriented to the production of heating equipment.

At the same time, the name “Conord” appeared, which is an abbreviation for the words “Heating Boilers, Non-Standard Equipment, Rostov-on-Don.” The newly born plant began its activities with the production of the DON-16 boiler, famous throughout the USSR.

Heating equipment “Conord”

Today it is a modern enterprise, the technical equipment of which does not in any way remind of its advanced age. The production lines are equipped with the latest high-precision laser machines, imported presses and robots, which allow us to quickly and efficiently produce reliable and affordable devices. The main part of the range consists of gas water heaters, as well as heating boilers - gas, solid fuel and combined.

The range of boilers is quite diverse. First of all, the products differ in the gas burner device used (for short, they call it automatic). Three varieties are available.

Automation AGU-T-M (Russia)

A budget option with a minimal set of functions. Despite its simplicity, it has a number of advantages:

• is cheap;
• does not require power supply (a bimetallic plate is used as a temperature sensor);
• does not impose special requirements on operating conditions and is inexpensive to repair (replacing the bimetallic plate - the only “weak link” - costs only 50 rubles).

This type of automation is quite common in our country and its use is not limited to the Conord brand. You can also see it in such Russian boilers as Mimax and some others.

There is no ignition system in the AGU-T-M, so the boiler has to be started using a lighter or a match.

Automation Euro SIT (Italy)

A boiler with such automation will be more expensive, but it simplifies setting the operating mode and ensures a higher level of safety. It contains:

• igniter with safety device (thermocouple);
• sectional burner with Polidoro tubes;
• gas valve SIT;
• temperature sensor;
• traction sensor

Unlike AGU-T-M, this automation reacts not only to gas shutdown, but also to deterioration of draft in the chimney.

The coolant temperature is set using a thermostat and is maintained automatically by a gas valve.

A piezoelectric spark gap is used to ignite the boiler.

Honeywell (USA)

The automation is of the same type as Euro SIT, only other materials are used for the manufacture of some elements.

An economy mode function has been added, to enter which the ignition knob must be turned all the way.

Conord boilers are also divided into single-circuit and double-circuit.

The former are intended for connection only to the heating system, the latter can additionally perform the function of an instantaneous gas water heater.

Unlike many other boilers with two circuits, Conord does not turn off the heating while using hot water. The 2nd circuit heat exchanger is heated by the smoke pipes. But still, the amount of heat supplied to the heating circuit decreases at this time.

Navien boilers from the largest Korean manufacturer, as a rule, work properly. But it is still a technique, and sometimes it can fail. Let's look at the types of malfunctions of the Navien boiler, as well as ways to troubleshoot problems.

We’ll talk about the functions of an inverter for a heating boiler in this topic.

Do you know why double-circuit gas boilers are purchased more often than single-circuit ones? Using this link https://microklimat.pro/otopitelnoe-oborudovanie/kotly/dvuxkonturnye-gazovye-kotly-dlya-otopleniya-chastnogo-doma.html we will consider the advantages of this type of equipment, as well as installation and selection features.

Danko gas boilers - technical characteristics of models, reviews from owners

Today we will talk about Danko gas boilers: you will find out what categories they are divided into, what their advantages are, how to install them and much more. You will also read reviews from those who have already installed them at home.

About company

is engaged in the production of heating equipment of various types - it produces gas, electric and solid fuel boilers, heaters and converters. The first products entered the market in 2002. The batch consisted of only 49 units of equipment. Today the company has about 850 thousand units of products sold. The production uses advanced equipment from foreign companies from Italy, Denmark, and Finland.

About the manufacturer

The Danko trademark is managed by PJSC Agroresurs; the first batch of boiler units was produced in 2002. The company is represented in the markets of Ukraine, Russia, Belarus and Moldova, where it has established itself as a manufacturer of relatively reliable and efficient gas boiler units for their price. It’s not uncommon to find the first batches of 2002 in homes.

The design and principle of operation of Danko gas boilers in a section using the example of a double-circuit steel model 12VSR.

Heating boilers are produced using modern foreign equipment, automation is imported from Italy in finished form. Almost all boiler units have high efficiency - over 90%. However, there are also disadvantages - the assembly is of insufficient quality, problems with the automation are possible during operation, due to the simplicity of the device and low cost, the boilers do not have a wide range of functionality or a set of protective systems. Installers note the relative complexity of installation and connection.

In practice, during strong gusts of wind in versions with a horizontal gas duct, the burner often blows out and the flame goes out, but the automation does an excellent job and turns off the gas supply. After this, the boiler must be ignited manually. The above-described disadvantages are typical for any inexpensive boilers of Russian, Ukrainian or Belarusian production.

Advantages

How to choose?

Boilers are divided into the following types:

The lineup

The line is represented by five series:

• Wall-mounted. Two modifications - 23 ZKE and 23 VKE. Double-circuit modifications. Each circuit has its own heat exchanger. For heating - copper, for hot water supply - steel.
• Parapet. 8 modifications - 7, 10, 12.5 and 15.5 kW. They are compact. Single-circuit. No smoke. Can be installed in apartments with an area of ​​140 square meters. Heat exchanger – steel.
• Steel. 22 models differ in power, number of circuits and location of chimneys.
• Cast iron. All have an open chamber. Cast iron radiators last approximately 25 years.
• With pump. 4 modifications. They work to heat the room and heat hot water. Steel heat exchangers. Related security systems.

Boiler design using the example of Danko 10/12

The model has a built-in water heater - it can be used to heat a private home and heat hot water. Appearance: rectangular cabinet. The facade is equipped with a door that closes and provides access to the elements responsible for ignition. Comprises:

• burners;
• heat exchanger;
• gas automation;
• decorative casing.

The automatic unit is responsible for supplying fuel to the burners - main and ignition, and for regulating the water temperature. Gas flow stops immediately if:

• the flame went out;
• the gas pressure has dropped below the permissible value;
• there is no draft in the chimney;
• The coolant temperature reached 90 °C.

Double-circuit modifications consist of structural elements:

• chimney duct;
• blower fan;
• gas burner;
• heat exchangers – primary and secondary;
• hydraulic unit;
• connecting fittings;
• pump for forced water circulation;
• expansion tank;
• an automation unit that controls the units of the device.

A distinctive feature is that all components are produced by European companies. This is a plus in favor of the reliability and cost-effectiveness of Danko brand products.

Additional systems

In the design of gas heaters, the manufacturer has additionally provided:

• water temperature sensors - triggered when boiling, turning off the system;
• a protective block that shuts off the gas supply when the wick goes out;
• a block that stops equipment operation in the absence of traction;
• draft control unit - to adjust the flame;
• multifaceted protection unit – turns off the device in case of any type of threat;
• intelligent block - for distributing liquid flows.

Installation

It is necessary to take into account the rules for installing gas equipment:

• The power is selected according to the heating.
• There must be at least 25 cm between the housing installed on a fire-resistant horizontal platform and a non-combustible wall.
• The device can be installed near fire-resistant walls if they are sheathed with steel sheets.
• The width of the passage in front of the facade is from 1 m.
• To improve water circulation, the installation should be lower than the level of heating devices.
• The expansion tank is located at the very top of the system.
• The minimum length of the chimney is 5 m.
• If the chimney is located outside, it must be insulated.
• The diameter of the smoke outlet must exceed the diameter of the smoke outlet pipe.
• At the junction of the boiler and the chimney, it is necessary to seal it with a solution of cement or clay.

Boiler installation

Installation of Danko gas boilers and connection to the gas main is quite easy. For comfortable operation, the housing includes left and right connections. When installing, it is very important to follow the following expert advice:

1. The gas supply is regulated manually using automation. To increase the power of the unit, set the required mode using a rotating wheel.
2. The Danko wall-mounted gas boiler is mounted using anchor bolts. During operation, the maximum weight of the device is 80-100 kg. It turns out that the fasteners must be very reliable to withstand such a load. With proper installation of the boiler, possible excessive fuel consumption and other problems can be eliminated.
3. To minimize gas consumption, an external temperature sensor can be used. The operation of the device is to determine the ambient temperature, as well as auto-adjust the specified mode of the boiler equipment. The temperature sensor works in this way: it records the ambient temperature and transmits information to the controller. Automation detects changes and introduces them into the specified temperature regime. As a result, gas consumption becomes lower.
4. Chimney – can be connected to a classic and coaxial smoke exhaust system.

Fire safety requirements for the installation of parapet devices are not as high as for atmospheric models. Therefore, in apartments it is recommended to install models with a closed combustion chamber.

The article described all the distinctive features of the brand’s heating devices, the installation of boilers, and examined their possible operating problems: why a Danko gas boiler goes out, goes out and takes up a lot of fuel. Take note of the recommendations of experts, reviews of owners, and the heating unit will serve you for a long time.

Operation and Maintenance

Commissioning is possible after acceptance by representatives of the gas service. An installation diagram is attached to the instructions. Installation is quite simple, but it is better to trust it to specialists. Gas workers who take the device into operation provide appropriate instructions. The modification is selected according to the project completed by the gas service, which necessarily notes the power of the device and its type. Safety regulations:

• Maintenance of the device can be performed by those who have attended the instructions.
• In the event of a breakdown, immediately turn off the taps.
• If you smell gas, turn off the valve, open the windows and call the gas workers.
• Keep the device clean and in good working order.
• Clean the chimney as often as indicated in the instructions.
• Check the fullness of the system weekly to see if there is water in the expansion tank.
• At the end of the service life of the device provided by the manufacturer, invite a specialist for advice on whether it can continue to be used.

How to light a Danko gas boiler

Identification of boiler control elements.

1. Turn the mechanical temperature regulator counterclockwise until it stops.
2. Make sure that the tap on the gas pipeline inlet is open.
3. Press and hold the start button, then press and release the piezo button (several clicks may be required, repeat until the pilot burner lights up). Hold the start button for at least 30 seconds until the burner goes out when it is released. If the boiler has not been adjusted previously, it may be necessary to adjust the air supply by turning the nut on the ignition burner until the burner flame turns blue.
4. Turn the thermostat knob clockwise until the main burner turns on, then set the desired power.

The startup process differs slightly for configurations with different automation; the algorithm is described in detail in the operating instructions, an electronic copy of which is attached in the description of each model on the official website.

What problems happen?

The simplicity of Danko's design allows its owners to carry out minor repair work on their own. One of the most common problems is the burner blowing out. This is especially common in strong winds. Usually no fault is found, the wind is the culprit of the problem, but it is better to check the following points:

• Is there a check valve installed in the chimney? If not, then there will be no reverse thrust, which is why attenuation occurs.
• If the chimney is installed incorrectly, it becomes clogged with soot and other combustion products - it needs to be cleaned.

It happens that before the attenuation, extraneous noise is heard or increased fuel consumption is observed - this may indicate a failure of the controller. The task is to repair or replace a spare part.

Important! If you don’t want to deal with flame extinction, choose not a single-circuit, but a double-circuit boiler - wall-mounted or floor-standing. 2-circuit models do not have such disadvantages.

Another common problem is the pilot light going out. It goes out due to the activation of the thermostat, which shuts off the gas supply if the burner does not heat up to the desired temperature.

Before starting heating equipment

Important! Before installing boiler equipment, you must carefully study the instructions supplied with it. By operating the boiler correctly, you will be able to increase its service life and obtain heat safely

Starting the boiler is a responsible event for which several operations must be performed:

By operating the boiler correctly, you will be able to increase its service life and obtain heat safely. Starting the boiler is a responsible event for which several operations must be performed:

• You should fill the heating system with coolant and check the gas connections for leaks using a special device or soap emulsion
• Check the chimney for the presence of draft, and also make sure that there is no gas contamination in the room where the equipment is installed
• Be sure to ventilate the room by first turning off the gas valve.

Before installing the boiler in a previously used system, it will be necessary to flush the pipes and radiators. Filling the system and replenishing it with contaminated water or water with rust or sand is extremely undesirable! Otherwise, you risk getting a noisy boiler and a high probability of damage to the heat exchanger. The correct solution is to monitor the equipment being used accordingly, as indicated in the instructions.

Accompanying work when starting a gas boiler

Power is supplied, the heating regulator is set to the desired position. The appearance of a hum indicates that the pump is starting to operate. Using a screwdriver, slightly unscrew the cap before water begins to leak out, then return the cap to its original position. This is done several times until the gurgling sounds disappear.

The electric ignition of the boiler is triggered and it turns on. The pressure in the system is regulated by adding coolant. The system with circuits gradually heats up and enters operating mode. The effectiveness of the work depends on the accuracy of the preparatory stages.

Crimping

Pressure testing of heating pipes is carried out to identify possible leaks

The procedure is carried out to detect leaks. Liquid or air is pumped into the system and a ten-minute break is taken, then the pressure gauge readings are checked. Constant values ​​indicate the tightness of the circuits and connections.

Sometimes pressure testing is neglected, for example, due to the lack of a pump, but carelessness threatens to cut off the heat supply in the dead of winter. The procedure is repeated after the end of the heating season in preparation for the next one.

Washing

The process is intended to clean the system of debris. The taps on all radiators are opened, and containers are placed under them to collect water. A pressure of 4 bar is established in the system, the flow of liquid flushes the pipes and batteries from contaminants. In advanced cases, the procedure is performed several times.

There are 3 cleaning methods:

• Mechanical. Scale from the radiator is removed with a vacuum cleaner, scraper, or brush after soaking the elements in cleaning solutions.
• Chemical. Acidic solutions are pumped into the booster and driven for several hours. The method removes carbonate and ferrous deposits well.
• Hydrodynamic. Injecting liquid under pressure.

Operating principle of the boiler

Gas heaters may differ in design and technical parameters, but the principle of creating heat in the house is the same - heating the coolant (water/antifreeze) with combustion gas (natural/liquefied). Supplying gaseous fuel to a residential area is not the easiest or safest thing, but consumers are attracted to gas, its comparative cheapness and versatility.

Blue fuel can be used not only for heating, but also for heating domestic water, using columns or dual-circuit heater models. Modern equipment is equipped with effective safety systems that prevent all possible emergency situations. Nevertheless, there are operating rules that must be followed and are a guarantee of safe operation.

How to choose?

Before you start choosing a model, you need to determine the functional purpose of the boiler and its power. Double-circuit units should be selected if you plan to equip not only heating, but also hot water supply

Particular attention should be paid to the heat transfer coefficient of the device, which is especially important when calculating the power of the heating system in regions with cold climates. Convection models have the highest efficiency. This type of design is presented in many Danko floor-standing appliances and is recommended for use in northern regions

This type of design is presented in many Danko floor-standing appliances and is recommended for use in northern regions.

Judging by the reviews of the owners, it was convection boilers that showed their best performance when heating a private home in harsh conditions. In addition, floor-standing devices are non-volatile. In the event of a power outage, they will not leave the house without heat. The most popular model among floor-standing appliances is the Danko 18BC model. The boiler has dimensions of 41x85x49.7 cm, weighs 81 kg and is designed to heat a room up to 170 m².

For heating country houses or when installing a heating system in southern and temperate latitudes, wall-mounted and parapet units are quite suitable. These devices can effectively warm a medium-sized room and provide residents with uninterrupted hot water supply. The disadvantage of such devices is the presence of electronic ignition, which does not allow the boiler to light in the absence of electricity.

Many models are equipped with frost protection, which is important when operating the device in conditions of temperature changes in the absence of owners, when it is not possible to force the device to turn on or off

When choosing equipment, you should also pay attention to fuel consumption. Single-circuit appliances consume significantly less gas than dual-circuit models

For example, a floor-mounted single-circuit unit of the Danko 8 brand, having a heat transfer coefficient of 92% and capable of effectively heating a room of 70 square meters, consumes only 0.9 cubic meters of gas per hour, while some double-circuit boilers consume 2.5 and more than cubic meters of fuel.

How to serve

Maintenance of Conord boilers consists of maintaining the cleanliness of the body, timely removal of soot or ash from the burner and performing other necessary procedures.

Most of the work is performed by the owner of the unit, but for some activities it is necessary to invite a specialist from a warranty or service organization. This must be done annually, or as urgently necessary - in case of problems or breakdown of the boiler.

Attempts at self-repair can cause permanent failure, so complex operations should be entrusted to professionals.

Any attempt to independently interfere with the boiler design will be regarded as termination of the warranty agreement at the initiative of the owner.

How to set up the heating system after starting the boiler

Heating system adjustment

To set up the heating system, we will need to carry out minor manipulations with the control valves. The fact is that almost all installation schemes for individual heating systems have one small drawback - the last batteries from the boiler, as a rule, do not have enough thermal energy. It simply does not reach there in the required volume and we will need to eliminate this deficiency by evenly distributing the supply of hot water between all heating devices.

This is not difficult - the control taps of the first two or three batteries need to be tightened a little. If you go from the boiler, then the tap of the first battery is turned halfway, the second a little less, and the third even less. Here you will have to experiment - it may take several days to achieve uniform heating of all batteries. But this no longer matters, because in general the heating system works normally, and the house is warm.

How to start a heating boiler

This is how, without any effort, the boiler is started for the first time and the heating system is set up. As you can see, there is nothing complicated about it, and it is not worth the money that service center representatives charge for it. Better spend it on purchasing an electronic room temperature control system - this programmer will reduce the energy consumption of a wall-mounted heating boiler!

Precautionary measures

Despite the desire of manufacturers to ensure the safety of gas appliances, they can still become a source of danger.

The Ministry of Emergency Situations regularly reminds owners of any gas-powered equipment about the following precautions:

Gas boilers Conord: review, design, automation

It's no secret that imported floor-standing gas boilers are of higher quality compared to domestic boilers. This applies to the material used to make the elements, the reliability of the automation, and the assembly of the device. However, the price of imported analogues differs noticeably upward. Our task is to find a Russian-assembled gas boiler with an optimal price-quality ratio.

I propose to disassemble Conord floor-standing gas boilers, reviews of which can increasingly be found on various thematic forums. Let's consider the model range, technical characteristics, device, types of automation (gas burner devices), using the instructions for use.

Model range and description of Conord boilers

Conord floor-standing gas boilers are available with capacities from 8 to 30 kW. They come as single-circuit: KSts-G-8, KSts-G-10, KSts-G-12, KSts-G-16, KSts-G-20, KSts-G-25, KSts-G-30;

and double-circuit: KSts-GV-10, KSts-GV-12, KSts-GV-16, KSts-GV-20, KSts-GV-25, KSts-GV-30.

Single-circuit ones can only be used for heating from 30 to 300 m2. Conord double-circuit gas boilers can be used for both water heating and hot water supply (DHW).

Floor-standing gas boilers Conord

It is important to note that if you need a double-circuit boiler to fully use the DHW circuit, you need to buy a Conord boiler with a power rating of 20-25 kW. In this case, it will produce about 10-12 liters of hot domestic water per minute

There is no point in buying, for example, a double-circuit boiler KSts-GV-12 with a power of 12 kW. It will not give us a good volume of hot water.

Boilers can be used in both open and closed heating systems.

Installation of floor-standing gas boilers Conord

The boiler consists of a steel firebox 3 mm thick, a casing, a water jacket, smoke pipes with turbulators built into them to increase the efficiency of the boiler, a gas burner device (automation), a layer of thermal insulation made of basalt cardboard, and a thermometer to monitor the temperature of the coolant. In double-circuit models, a special coil for the water circuit is installed around the smoke pipes.

The coolant inlet and outlet, as well as the DHW coil, are located on the rear side of the boiler body. The thread diameter of the heating connection pipes for all models of this brand is 2 inches or 50 mm. For DHW circuit 1/2 or 15 mm. The chimney diameter for models with power from 8 to 12 kW is 115 mm, for 16 kW and above - 150 mm.

Conord boiler design

Due to the built-in turbulators and good thermal insulation, the efficiency of the Conord boiler reaches 90%. These heating devices are capable of operating at reduced gas pressure and are completely energy independent of electricity. The manufacturer claims a boiler service life of 15 years and a factory warranty of 3 years, which is also indicated in the operating instructions.

Automation for gas boilers Conord

Three types of automation can be installed on floor-standing boilers of this brand:

— domestic type AGU-T-M

- Italian Euro SIT

In general, the automation, although not particularly sophisticated, is unpretentious. In the event of a breakdown, it is not difficult to find spare parts for it. For example, a bimetallic strip that often fails costs about 50 rubles.

Automation type AGU-T-M

Euro SIT automation consists of a sectional burner and Polidoro tubes, as well as a safety system: igniter with thermocouple, temperature sensor, SIT gas valve, draft sensor and wires. If the pilot burner goes out, the gas is turned off, or there is no draft in the chimney, the automatic system instantly shuts off the gas supply to the burner.

Ignition occurs by pressing the piezoelectric element button or using a match. The coolant temperature is provided by the gas valve and set by the thermostat knob.

Automation Euro SIT

Honeywell automation from an American manufacturer has similar technical characteristics to a Euro SIT gas burner device. The principle of operation is the same, it differs mainly in the manufacturer and material of some elements.

Ignition is carried out by pressing the handle to the right of the thermostat and then turning it to the stop position to operate the boiler in economical mode.

How to turn on a gas boiler

The main differences in switching methods depend not on the design of the boilers themselves, but on the type of automation that is installed in them.

For your information! That is, even different models from different manufacturers can turn on in the same way if they have the same automation system.

Danko boiler: how to turn it on and off correctly

Basically, the instructions on how to turn on the Danko gas boiler boil down to the following algorithm:

1. Check that the boiler is turned off (the thermostat knob should indicate ignition).
2. Next you need to open the tap in front of the boiler.
3. The ignition button must be pressed and held in this position for a while.
4. With your other hand you need to press the ignition button several times (until the gas in the burner ignites).
5. After ignition, the ignition button must be held for about 10 seconds.
6. After this, you need to make sure that the burner is still burning.
7. Make adjustments by turning the thermostat knob.

Important! If the burner suddenly goes out, then you need to repeat attempts to ignite the boiler after 3 minutes. or more

Switching off is done by turning the thermostat knob and closing the tap in front of the boiler.

Turning on the Conord boiler

You can ignite the gas in the burner of this boiler using a semi-automatic method. How to do it:

1. The regulator should be in the extreme position.
2. Then you need to push the wheel down for a period of 5 to 6 seconds. At this time, gas flow into the chamber begins.
3. By pressing the ignition button, a piezoelectric element is activated, which ignites the mixture.
4. After the fire appears, you need to hold the wheel in the down position for a little longer (about 10 seconds).
5. Next you need to start setting the desired temperature.

Dangerous situations

The greatest danger is a malfunction associated with the operation of the burners. If the flame goes out, gas may accumulate in the room, which will subsequently cause an explosion. Reasons for the fire going out:

• gas pressure has dropped below the permissible norm;
• no draft in the chimney;
• the supply voltage has disappeared;
• The pilot light went out.

In an emergency, it is necessary to immediately shut off the fuel supply to the burners - automatically or manually. Modern versions are equipped with automation devices necessary for prompt shutdown of equipment. The operation of such devices is not only convenient, but also safe.

How to prevent gas accumulation indoors

Modern safety standards provide for the installation of gas analyzers in boiler rooms; they are necessary for signaling when gas appears in the room. A special electronic valve reacts to their signals, automatically stopping the flow of fuel to the burners.

Advantages and disadvantages

The advantages of Danko floor-standing boilers include:

• The design of the units is optimized for maximum efficient and economical operation in all conditions.
• Boiler components and parts are made of high-quality materials using modern equipment.
• Fuel consumption is reduced by one and a half times compared to products from other companies.
• The units are designed for a long service life.
• Attractive appearance, compact size.
• Relatively low price.

The disadvantages of Danko boilers can be considered:

• Demanding requirements for water quality, the need to use softening filters.
• Requires annual inspection and maintenance.
• There are often cases of random flame extinction due to the backdraft effect.

NOTE!

The disadvantages of Danko boilers can partially be overcome through proper installation, and are partially a specific design feature.

Care tips and advice

Proper maintenance of the boiler, performed regularly, will help keep it in working condition for a long time and avoid various accidents and accidents. Otherwise, the unit may break even in the first year of operation. Performing several operations will prevent this from happening:

• even during normal operation of the boiler, you need to contact one of the organizations carrying out work in this area, so that a technician inspects the device for gas and water leaks, the condition of the sensors and chimney, and, if necessary, carries out repair work;
• You should always monitor the water pressure inside or at the outlet of the system. If it drops below 0.8 bar, then water needs to be added;
• The addition of water to the system is usually carried out directly through the boiler, where there is a special tap. In this case, the pressure of the added water must be greater than the pressure of water from the boiler. The supplemented water should only be cold (up to 35°C).

For your information! To spend winter evenings warm and comfortable, you need to properly care for your boiler and also know how to light it.

Depending on the model and manufacturer, this process will be slightly different due to differences in design. This can be clarified in the instructions supplied with the device.

Boilers operating on natural gas are quite often used to heat private houses and cottages. There are no particular difficulties in operating such devices.

It is only important to carry out the first start-up of the heating system correctly and light the gas boiler. It is best to entrust this procedure to a qualified specialist.

Flue (atmospheric) boiler

This heating unit operates on natural draft, so the wind can have a significant impact on the combustion process. If there is no draft or the air begins to move in the opposite direction, the automatic system is activated, stopping the gas supply.

If the owners notice that their gas boiler regularly blows out, then they need to determine the cause of this problem. To do this, you need to contact a monitoring organization, whose specialists will check the operation of the chimney.

Depending on what conclusion the experts come to, it will be possible to begin to take measures. Let's look at what needs to be done to stop the boiler from blowing with the wind.

At the first stage, you need to make sure that the chimney is functioning normally and that there are no blockages or ice plugs in it. If this problem does not exist, then other causes of poor traction need to be ruled out.

Installation of the "fungus"

Sometimes, in order to solve the problem, such a simple measure as installing a “fungus” on the end of the pipe is enough. This simple device reduces the likelihood of backdraft. There are several types of fungi:

• cone-shaped;
• in the shape of a ring, larger in diameter than the chimney;
• combined, consisting of a ring and a cone.

Fungus functions:

• dispersion of directed air flow;
• creation of vortices, due to which reverse thrust does not develop.

Another solution to the problem could be to increase the height of the chimney to increase the draft force. Sometimes this has to be done after several years of normal operation of the boiler due to an obstacle that has appeared. For example, if a taller building or other high-rise object is built next to the house.

"Break traction"

If it is impossible to increase the height of the chimney, it is worth trying to organize a so-called “draft break”. To do this, a special device is inserted into the pipe, which prevents the formation of backdraft.

The simplest version of the device has the shape of a truncated cone; it is installed with the wide end towards the boiler. The point of installing such a device is that the air flow entering the pipe loses its strength and forms turbulence, since it cannot freely pass through the narrow part of the cone.

Large chimney diameter

Many people believe that the larger the diameter of the chimney, the better the natural draft. But this is a wrong opinion; moreover, too large a chimney diameter can lead to the burner being blown out by the wind. Why is this happening? The fact is that to create enough thrust, three conditions must be met:

• supply of sufficient air to the firebox to ensure combustion processes;
• achieving a high temperature in the current for the most complete combustion of flue gas;
• heating the inner walls of the chimney pipe.

In order to fulfill the last condition, the inside of the chimney must be assembled from materials with low thermal conductivity. It is clear that the larger the internal diameter of the chimney, the longer it will take to heat them up.

That is, the cause of poor boiler performance can be not only the entry of air flows into the pipe and the creation of reverse draft, but also the insufficient force of forward draft due to the fact that the internal walls of the chimney pipe do not have time to warm up.

To solve this problem, you do not need to disassemble the old chimney; just insert a pipe of a smaller diameter into it. In this case, heating of the inner walls will occur much faster, this will increase the force of direct thrust.

Posting rules

1. The area of ​​the room in which the heater is installed is at least 7.5 m².
2. Ceilings – from 2.2 m.
3. There must be a window providing access to air from the street.

Installation

The thermal power of the unit must be selected according to the design for heating the house in order to ensure a sanitary thermal regime in the premises.

The lowest ambient temperature during operation is not lower than 5 C. When installing the boiler, the circulation speed of the centrifugal pump and the total volume of coolant in the network must be taken into account.

Basic provisions when installing a Danko boiler:

1. Before installing the unit, a heat-resistant horizontal foundation is made. The walls are shielded with heat-resistant materials, the gap between the wall and the boiler is left at least 250 mm. The insulating layer should extend beyond the dimensions of the housing by 150 mm.
2. In front of the front working wall of the device, free passage is at least 100 cm.
3. It is forbidden to wall up the base of the unit into the floor, since the process of air intake into the combustion chamber will be disrupted.

Why does the Zhytomyr gas boiler not light up?

boiler shutdown

is the lack of traction, but if we talk about the technical part, the following is most likely: 1. the thermocouple-valve cable connection has oxidized; 2. The thermocouple is incorrectly set relative to the pilot burner; 3. the pilot burner or tube is clogged (dirt, spider?); N 4.

Interesting materials:

Why is a safety valve needed in a boiler? What is a preamplifier for? Why do you need a grill press? What is a projector for? What is the starting current for?

Second group with a steel heat exchanger:

The Conord boiler with the design of a steel cylindrical heat exchanger made of cold-rolled metal is offered by the plant in single- and double-circuit versions. The service life is reduced compared to cast iron to 15 years. The designs use two automation options.

The first option: SIT automation from an Italian company known for its quality throughout the world. It is installed in the vast majority of all manufactured boilers in the European Union, such famous devices as: IMMERGAS, Fondital, Vaillant, Bosch and many others. The SIT valve allows you to guarantee a stable set temperature.

In addition, automation controls stable operation with a reduced gas pressure in the city pipeline. So the nominal value provides for operation with a pressure of 1.3 kPa, but a drop to 0.6 kPa is not a big problem and the Conord gas boiler continues to operate steadily, despite the fact that this is 46% less than required.

Single-circuit, with automatic SIT – heating only:

KSts-G-8S Heating capacity =8 kW KSts-G-10S Heating capacity =10 kW KSts-G-12S Heating capacity =12 kW KSts-G-16S Heating capacity =16 kW KSts-G-20S Heating capacity =20 kW KSts-G-25S Heating capacity =26 kW KSts-G-30S Heating capacity =30 kW KSts-G-40S Heating capacity =40 kW KSts-G-50S Heating capacity =50 kW

Single-circuit, with thermohydraulic automation

The second option is more budget-friendly, equipped with domestically developed AGU-T-M automatic equipment. AGU is an automatic gas burner device, consisting of nozzles and safety automation. The main manufacturers are Mimax and Tagonrog. ASU automation consists of:

1. temperature sensor;
2. igniter with thermo-bimetallic plate;
3. adjusting screw with lever;
4. gas valve;
5. block crane;
6. connecting parts.

Ignition order:

1. We check the draft, move the damper, light the igniter.
2. Press the gas valve and light the wick. We fix and do not release the button until the bimetallic plate heats up.
3. While continuing to hold the button, follow the lever. It will creep onto the inscription “on the button”, we need to wait for the moment when it is fixed.
4. Release the gas valve and set the required temperature using the control knob.

Domestic automation makes it possible to buy a Conord boiler a little cheaper. In contrast to European analogues, it has the simplest design. It is non-volatile - it does not require power from the electrical network. The starting process is carried out manually by igniting with matches or a lighter. By the way, thermo-hydraulic automation type AGU-T-M is widely used in Russian gas boilers

According to customer reviews, such automation is completely unpretentious, and the Conord floor-standing boiler equipped with it is not “capricious”. In addition, it is not difficult to find spare parts on the market even far from city centers. The prices are also not satisfactory, for example, one of the frequently requested parts - a bimetallic plate - is found everywhere for no more than 100 rubles.

Double-circuit with DHW and SIT automatic control system

The Conord floor-standing gas boiler, when equipped with two circuits, copes with the task of heating buildings and at the same time is capable of preparing hot water used for household needs. The design uses the proven modulation function. Burner operation using modulation significantly increases the efficiency of hot water supply.
