Conord gas boiler: technical specifications, how to turn on a floor heating boiler, instructions for use for a private home

Overview of markings and its interpretation

You can find out about some of the technical characteristics of the boiler if you pay attention to the markings. It may have the following form: KSts-G-10S or KSts-GV-12

The letter "K" stands for "cauldron". The letter “C” indicates that it is made of steel. If the design has a cylindrical firebox, you can recognize this by the letter “C”.

Gas boiler equipment is designated by the supplier with the letter “G”. If you have a boiler in front of you that provides the function of hot water supply, then you can find out about this by two letters - “GW”. After the letter designation you will see numbers. They indicate the maximum power level.

In order to determine the required power when purchasing a boiler, the area of ​​the room is taken into account. For every 10 m2 you will need 1 kW of power. This is true if the ceiling height is 2.5 m

It is important to consider that this choice is relevant for the average level of heat loss

Floor steel models Conord

Let us immediately note that all boilers of this brand are produced in a floor-standing version. “Steel” boilers are those whose heat exchanger is made of steel. It is easy to find such a device in a catalog or price list by the marking, which begins with the letters “KS” (steel boiler).

For example, it is the steel heat exchanger that is installed in the boiler of the KSC-G-16 brand.

Here the letter “C” denotes the cylindrical shape of the heat exchanger, “G” is the type of fuel (gas), and the number “16” is the power in kilowatts.

The presence of the letter “B” in the marking (for example, KSC-GV-20) means that the boiler is 2-circuit.

Boilers with a steel heat exchanger are lighter and heat up quickly. However, they are less reliable and not as durable as cast iron. A significant disadvantage of steel is its susceptibility to corrosion.

How they work

The firebox is made of 3 mm steel sheets. There is a water jacket, a gas burner unit and smoke pipes with turbulators, which increase the efficiency of the device. The gas burner unit operates automatically - the power is modulated. Basalt cardboard is used for thermal insulation. There is a thermometer to visually monitor the water temperature.

If the model is 2-circuit, then the chimneys are equipped with a coil for hot water supply. The input-output of the latter is located on the rear panel of the case. The diameter of the pipes is 2 inches / 5 cm. For hot water supply - 0.5 inches or 1.5 cm. Devices with a power of 8-12 kW have a chimney with a diameter of 11.5 cm. 16 kW - 15 cm. There are modifications with and without circulation pumps .

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.

Causes of gas equipment failure

Despite the high quality of products from the domestic manufacturer Conord, such gas boilers can fail over time.

The problem is not always the natural wear of parts, and, as a rule, this occurs only after at least 5 years after the start of operation.

One of the most common causes of breakdown of gas boilers is a sudden shutdown or a strong surge in electricity, as a result of which the device settings are simply lost

If the equipment breaks down almost immediately after installation, this may occur as a result of a simple failure in the settings or a voltage drop.

Gas boiler malfunctions often occur for the following reasons:

1. Voltage fluctuations in the network. Sudden surges in voltage can lead to a short circuit and, accordingly, a blown fuse that will need to be replaced with a working part. In this case, it is recommended to purchase a high-quality stabilizer, which will allow you to no longer worry about voltage failures in the network.
2. Poor quality water. The operation of double-circuit boilers, which are also responsible for heating water, may experience malfunctions. Heating low-quality water renders the flow-through heat exchanger unusable, so the only way out in this situation is to install a full-fledged water purification system.
3. Incorrect installation. The installation of gas heating equipment should be carried out by a qualified specialist, since even the slightest mistake can lead to serious consequences. For example, incorrectly performed piping of a cast-iron gas boiler can lead to its body simply cracking at low temperatures.

In addition, the proper operation of gas equipment can be disrupted by weather conditions, which can cause the boiler to become unusable.

Since in frosty weather many users turn on the heating at full power, the pressure in the gas pipeline system decreases, which means that the boiler simply will not be able to produce the promised heat.

As an additional source of heating, you can install a solid fuel boiler on coal, which will allow you not to overload the gas boiler, and at the same time ensure sufficient temperature inside the room

If you have a conventional Conord gas boiler (without heating hot water), it is recommended to install a good stabilizer, but it is better not to save on the purchase. So, you don’t have to change the fuse after every power failure, and even more so, spend a lot of money on purchasing a replacement for a burnt-out pump.

About the manufacturer

The plant began its existence in 1947 with a small production workshop and a scientific department. In 1979, the first proprietary model was put into production - the DON-16 heating boiler, which for a long time was installed in almost all houses with gas heating. With the development of technology and the growth of production capacity, the Conord plant is developing new models that are more economical and reliable.

The modern history of the plant begins in 2012, when the production line was completely re-equipped and new equipment from the Japanese company Amada was installed. This made it possible to begin producing new models that are close to European standards.

Today the Conord plant produces more than fifty types of its own products:

• gas boilers;
• geysers DON and Conord;
• heating devices AOGV;
• electric water heaters;
• solid fuel boilers;
• pellet units and burners for them;
• industrial heating boilers JUMBOJET.

Advantages of Conord boilers

All gas boilers from Conord have certain advantages:

Excellent technical characteristics allowing to achieve high efficiency of 90%. Modern, reliable automation that eliminates emergency situations. Possibility of installation into an existing heating circuit with minimal modifications.

With natural circulation of coolant in the heating system, the Conord floor-standing boiler is completely energy independent, which is very important for remote villages.

In addition to heating rooms, dual-circuit models are capable of providing hot water for domestic needs.

Such advantages and characteristics are highly appreciated by users who have installed Konorod gas units, which is confirmed by numerous positive reviews.

Installation nuances

Reviews from owners confirm that Conord may go out. Provoking factors:

• The burner is dirty. Before turning on the device, you should clean the nozzles with a brush or vacuum cleaner.
• There is not enough oxygen to start the burner. The air nozzles should be cleaned and the room ventilated.
• Thermostat contacts have oxidized. Cleaning needs to be done.
• Automation sensors are broken.

If the coolant cools down too much, you need to switch the thermostat to maximum or increase the flow of gas to the burner, if the instructions allow such an action.

Features of summer use

In summer it is necessary to turn off the heating circuit. To do this, turn off the tap at the coolant inlet. When one pilot burner is running, the water will heat up to 60 °C in 60 minutes. If water is not consumed, it will retain heat for about two hours - it can be used for domestic needs. When the device heats up and there is no active consumption of water, it is turned off so that the water does not boil.

Recommendations for the use of equipment

Reviews of Conord boilers indicate that they are chosen mainly due to their reliability and affordable price. However, many consumers complain about one drawback: boilers often go out for no reason. This may be due to the following factors:

• the burner is dirty and you need to clean the gas and air supply nozzles with a vacuum cleaner and brush;
• there is not enough air for the pilot burner to operate fully. To fix this, you need to clean the air supply nozzles and improve the ventilation of the room;
• Thermostat contacts have oxidized. They need to be cleaned or “stirred up”;
• The draft sensor or flame sensor is broken.
• Some reasons, as you have seen, can be eliminated yourself, but to eliminate others it is better to call the service department.

Also, the temperature of the coolant in the system can drop significantly. To eliminate this, move the thermostat switch to the maximum position or increase the gas supply to the burner, if such a recommendation is included in the instructions for the boiler.

Also, Conord boilers have their own operating characteristics in the summer. So, to turn off the heating circuit, you need to turn off the water supply tap. If only the pilot burner is working, the water heats up to 60 degrees in an hour. If there is no further water consumption, then it will be enough for a couple of hours for small household needs. After heating the boiler, if active consumption of hot water is not planned, it should be turned off, otherwise the water will boil and the boiler may break.

Types of burners

According to their design and functional differences, burner devices are divided into:

By purpose:

• for high power industrial equipment
• for household equipment.

By type of fuel used:

• devices for natural gas;
• devices for liquefied gas;
• universal devices.

By adjusting the flame:

• single-stage – capable of operating on/off;
• two-stage (as a variation - models with smooth modulation) - operate at full power, when the desired temperature is reached, the flame is reduced by half;
• modulating - boilers with a modulating burner are characterized by smooth adjustment of the flame power.

According to the principle of operation:

1. injection/atmospheric. They operate by supplying air from the room. They are installed respectively in open combustion chambers. Also used for old-style boiler models.
2. fan/supercharged. They work in isolated combustion chambers. Combustion air is supplied by a fan. According to their design features, they are divided into: - vortex (round-shaped nozzle holes) - direct-flow (shape of a narrow slot with a round/rectangular cross-section).
3. diffuse-kenetic. Air enters two simultaneously: one is mixed with gas fuel, the second is added directly to the chamber during combustion.

Setting up a gas boiler: how to correctly set the temperature, power

Gas equipment is found everywhere in apartments and country houses. You independently regulate the equipment, setting a comfortable temperature in the room. This way you are not dependent on utility companies and can save fuel at your own discretion. But for operation to be truly economical, correct settings of the gas boiler are important.

How to set up a boiler yourself

Why do you need proper adjustment of equipment:

• To save resources.
• To make the room comfortable, use hot water.
• To extend the life of the equipment.

You need to start with the right choice of boiler and its power. Consider the features of the room: the number and area of ​​windows, doors, quality of insulation, wall materials. The minimum calculation is based on heat losses per unit time. You will learn more about this in the article “How to calculate the power of a gas boiler.”

Gas boilers are divided into single-circuit and double-circuit. The latter perform heating on the heating and hot water supply (DHW) circuit. Single-circuit units provide heating only. Therefore, to obtain hot water, indirect heating boilers are installed.

Depending on the type of placement, equipment can be floor-mounted or wall-mounted. Units placed on the floor have greater power. Therefore, they are used for large areas (from 300 m²). Installation is carried out only in separate rooms (boiler rooms). These are models Baxi (“Baksi”), Buderus (“Buderus”), “Navien”, “Kiturami”.

Attachment appliances (Neva Lux, Arderia, Daewoo, Ariston, Bosch) fit perfectly in small apartments in the kitchen. Therefore, it is important to take into account all the nuances of the location. The comfort of residents, as well as the durability of the boiler, depend on the correct selection of parameters.

Power setting

The heating power depends on the modulation of the gas burner. If you choose an electronically controlled device, then it includes a thermostat that connects to a room thermometer. The adjustment occurs automatically: the thermometer measures the temperature in the room. As soon as it drops below a comfortable level, he gives a command to start the burner or increase the flame power.

In normal mode, the thermometer monitors the temperature in only one room. But if you install valves in front of each radiator, control will be in all rooms.

You can adjust the burner manually by operating the gas valve. This is true for atmospheric boilers with an open combustion chamber. Thus, in the Protherm “Cheetah” and “Protherm Bear” models, the valve is controlled by an electric motor. To change the settings, you need to go to the service menu. Most often, this is done by a specialist, and the user follows the steps specified in the instructions.

But we will still tell you how to call up the hidden menu for adjustments.

Before going into the menu and making settings, do this:

• Unscrew the taps on the batteries.
• Set the room thermostat to maximum values.
• In the user settings, set the maximum temperature that you use in severe frosts. The burner always turns off when the readings reach 5°C above the set values. For example, at +75 degrees, a shutdown will occur when it reaches 80 degrees.
• Cool the coolant to 30°C.

For Protherm Gepard:

• Hold down the Mode key on the panel. Once the display shows “0”, set the value to 35 by pressing “+” and “−”.
• Press Mode to confirm.
• As soon as d lights up on the screen. 0, enter the line number in the menu. Do this using “+” and “−” d.(number). To set the maximum burner power, select d.53, the minimum - d.52.
• Use Mode to move to parameter selection. Change it "+" "−".
• The installation receives automatic confirmation.
• Return to the original menu - hold Mode.

While adjusting using the panel, monitor the flame change and temperature rise.

For Proterm Panther the actions are different:

User manual

In order not to lose the warranty for the maintenance of your unit in any case, you do not need to carry out work on installing the boiler and repairing it yourself. Connecting the product, its proper configuration, and the first start-up must be carried out by service specialists. They will make a separate entry about the work performed in the passport of the unit you purchased. It is necessary to carry out preventative maintenance of the entire boiler once a year - this is also noted in the technical data sheet of the device. Failure to maintain such records may void your warranty.

The Conord burner may sometimes not ignite. This may happen because:

• There is a lot of dirt on the burner. Before turning on the structure, you need to clean the nozzles with a soft brush or just a vacuum cleaner.
• There may not be enough oxygen to start the burner quickly. Again, it is necessary to clean the nozzles that supply air, thoroughly ventilate the room, and try to light the burner again.
• Perhaps the contacts in the thermostat have simply oxidized. This is where the cleanup takes place.
• Automation sensors are broken.
• It is necessary to blow out the igniter or clean it of any existing dust or dirt.

If your coolant cools down very quickly, you just need to switch the thermostat to maximum settings or increase the supply of fuel to the burner, if only the device instructions allow this kind of action.

In the summer, you will need to turn off the heating circuit altogether. You just need to turn off the tap at the coolant inlet. If the burner works alone, the water will heat up to 60 degrees in 1 hour. If the heated liquid is not all removed at once, it will retain heat for about another 2 hours.

Domestic has already earned an excellent reputation in the domestic heating equipment market thanks to the production of high-quality equipment. Among users, Conord units, reviews of which have mostly positive features, are always in fairly high demand.

To learn how Conord gas boilers are produced, see the following video.

The quality of heating of the entire house depends on the serviceability of the gas boiler, which is especially important in the cold season. Even the slightest breakdown can cause the owner of the equipment to have a panic attack, since its repair can be too expensive

Agree, it is not always necessary to call a specialist, because you can independently figure out the reasons for the malfunction of the Conord gas boiler and repair the equipment yourself.

Despite the already established tendency to always blame the manufacturer, often gas boiler breakdowns have absolutely nothing to do with production features. They often arise due to a malfunction in the equipment settings, unstable pressure or voltage in the network.

Further in the article we will tell you what breakdowns of the Conord boiler occur most often, and how to independently restore its operation after another failure. In some cases, repairs may not be necessary because all you need to do to fix the problem is simply set the correct settings.

Product line

There are practically no wall-mounted boiler models in the brand’s line, so for a home heating system, consumers often purchase a Conord gas floor-standing boiler, which can be equipped with additional options. Floor-standing boiler models are produced in four series. The manufacturer makes all boilers from durable high-quality steel. To increase the stability of the boiler, its surface is treated with heat-resistant powder, which protects the device from high temperatures and loads.

Consumers who are interested in such a device as the Conord gas boiler, instructions for use are supplied by the manufacturer, should analyze devices from the following series:

1. KSC-G-S;

The power calculation does not include the power consumed by the hot water circuit. All parameters indicated in the table correspond to the operation of the device at rated heat output and established thermal equilibrium.

The prices presented on the website are not a public offer and may differ at points of sale.

Advantages

After reading reviews about the products of the Rostov enterprise, it is easy to understand that they are in high demand. The Russian consumer is attracted to Conrod products by:

• Cost - prices for Russian products are much lower than for European ones. Sometimes the difference is 50%. The cheapest 8 kW models, used for heating a private home, cost only 15,000 rubles.
• Long warranty. The manufacturer guarantees uninterrupted operation for fifteen years.
• Does not depend on electricity. A blackout, especially in winter, due to lack of electricity, is almost a disaster. Therefore, for volatile equipment it is necessary to install backup power - a generator or battery. There are no such problems with Conord.
• Easy to use. The abundance of functions, electronics and automation from other brands often causes unnecessary trouble.
• Quiet operation.
• High quality build.
• Good technical characteristics: Rostov boilers are practically not inferior to foreign analogues in productivity, efficiency, and heating speed.
• High efficiency - about 90%.

Advantages and disadvantages

The advantages of Conord gas boilers include:

• High quality assembly and manufacturing of components and parts.
• Boiler efficiency exceeds 90%.
• The non-volatile design allows the units to be used in any room or area.
• The service life of boilers is at least 15 years.
• Capable of operating at low gas pressure.
• The manufacturer's warranty on Conord boilers is 3 years.
• The price of the units is noticeably lower than that of other manufacturers.

The disadvantages of the units should be considered:

• The dimensions of the boilers are quite large and require a certain amount of space for installation and maintenance.
• The use of natural draft places increased demands on the design of the chimney and the creation of conditions for high-quality smoke removal.

Solid fuel boiler "Don"

The “Don” universal boiler operates on any solid fuel.
The non-volatile “Don” universal boiler can operate on any type of solid fuel. If necessary, a gas burner can be installed. It can work up to 8 hours on one load of coal.

The firebox is made of structural steel, which is highly resistant to corrosion. The firebox has decent volumes: firewood up to 60 cm long (depending on the model) can be placed in it; logs up to 60 cm in diameter can be used. The warranty service life of the Don boiler is 12 months.

The overall dimensions of the new Dons remain the same, so they are installed exactly in the place of the old ones and do not require reworking the system. The transition to gaseous fuel occurs by installing the burner in a special hole.

Technical parameters of universal heating boilers "Don" are given in the table.

Characteristics of the Don boiler (click to enlarge)

The installation of a universal boiler is subject to the same requirements as the installation of a gas boiler, with the exception of points relating to gas service. Read more about universal (combined) boilers here.

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 - no power supply is required. 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.

KSts-G-10N Heating capacity =10 kW KSts-G-12N Heating capacity =12 kW KSts-G-20N Heating capacity =20 kW KSts-G-25N Heating capacity =25 kW KSts-G-30N Heating capacity =30 kW

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.

In addition, the boiler will be turned off in the event of any breakdown or any other type of failure. You will be able to automatically adjust the heating temperature of the device, and if the fuel pressure level is too low, the device will provide rapid forced air injection to maintain the functionality of the device.

Disadvantages of Conord products:

• not the highest build quality of some models;
• the steel thickness will be no more than 3 mm;
• ban on the use of antifreeze.

Types

Conord floor-standing gas boilers do not need to be connected to the power supply. This means that the use of fans or pumps is eliminated.

The combustion chamber of all units is of an open type (atmospheric), circulation of liquids occurs either naturally or using an external circulation pump.

The fundamental difference in design is only the functional features:

• Single-circuit boilers designed for heating.
• Double-circuit, capable of preparing hot water for household needs simultaneously with heating the coolant for the heating system.

IMPORTANT! Most single-circuit models can be connected to an external indirect heating boiler, which makes them capable of providing hot water to the home in larger volumes than double-circuit models.

In addition, there are differences in the design of the heat exchanger:

• Steel heat exchangers 3mm thick.
• Cast iron components with increased efficiency.

In addition, there are different types of control automation. These are mechanical gas supply and adjustment units.

Exist:

• Italian SIT nodes. In the boiler marking they are designated by the letter S.
• Thermohydraulic elements. They are designated by the letter N.

Recently, American-made components have been installed in some boiler models, which expands the range of boilers. In the marking they are designated by the letter M.

Circulation pump

Air often accumulates in it, and its blades sometimes seem to get stuck (the boiler will display a corresponding error).

It is recommended to rotate the shaft manually before starting.

To do this, you need to remove the front panel of the housing, unscrew the central bolt on the pump and use a straight-bladed screwdriver to turn the shaft in the direction indicated by the arrow.

An air vent is installed above the pump. You need to pull the bright lid up and let the air escape.

Floor-standing boilers are usually more powerful than wall-mounted ones. If you need to heat a large room, it is better to choose this option. Floor-mounted gas boilers for home heating – overview of design options and models.

Read about the installation features of combined heating boilers in the following material.

Conclusion

At first, the system may make gurgling sounds, all because during startup it is impossible to bleed air down to the last atom. It will gradually be removed through the expansion tank valve. Periodically check the pressure on the pressure gauge - it should be within the operating range. Temperature adjustment and other boiler settings are described in the instructions for each model.

Device (automation)

The main element is the gas burner. It heats the heat exchanger in which the coolant is located.

It is supplied by gravity or under the action of a circulation pump (purchased separately and connected as an external component of the system) into the heating circuit.

For double-circuit models, a coil is installed around the smoke pipe to heat the hot water of the DHW circuit.

Smoke is exhausted naturally, using the chimney draft, to which the boiler should be connected during installation.

The heating system must be installed taking into account the placement levels of radiators that ensure natural circulation of the coolant.

If this is not possible, you have to use a circulation pump, which stabilizes the liquid movement mode, but makes the boiler energy-dependent.

Features of installation of Conord boilers

In order for the warranty to remain valid during its validity period, the equipment must be installed, configured and put into operation by specialists from a certified service center. They must also make an appropriate entry in the technical passport of the boiler. You should also carry out an annual preventive inspection of the equipment by specialists, which should also be indicated in the technical passport. The absence of such marks will also void the product warranty.

When installing, consider the following points:

• if the boiler will be placed on a combustible floor, be sure to install a fireproof substrate, which should exceed the overall dimensions of the equipment by 50 cm on all sides;
• in order for the water circulation in the system to be normal, the lower pipe must be located below the heating radiators;
• system pipes may be different. If welding is used for connection, it is advisable to leave several threaded connections for later repair;
• risers must be vertical , deviation within 3 mm per 3 meters of structure is allowed;
• horizontal sections must be laid with a slope for air removal of at least 10 mm per meter of structure;
• branches to heating devices must have a slope of at least 10 mm per meter of pipe;
• Shut-off valves must be installed at the outlet of the coil;
• the finished chimney to which the equipment will be connected must be located in the load-bearing wall of the building;
• if the chimney passes through an unheated area, it must be protected by thermal insulation;
• the diameter of the chimney must exceed the diameter of the outlet pipe so that the operation of the equipment is stable and the draft is sufficient;
• the chimney should not have ledges and be strictly vertical;
• all parameters, height and device must comply with regulatory documents and fire safety requirements;
• the gas boiler installation project must be previously agreed upon with special authorities.

Design Features

• Convenient adjustment. Heating is adjusted by a mechanical rotary regulator, which allows you to change the strength of the fire.
• Simple ignition - no complex automation, which in imported analogues often makes you nervous.
• Thanks to its special design, the cold-rolled steel heat exchanger is resistant to overheating, which significantly increases its service life.
• The burner is capable of operating even at the lowest gas pressure.
• Low heat loss - the body is thermally insulated.
• Dimensions are modest. Floor-standing units are always larger than wall-mounted units, but Conord’s dimensions are quite acceptable for small rooms. Stylish design - easily combined with modern interiors.
• The body is lined with steel sheets (3 mm thick): thanks to the powder coating, they are characterized by increased heat resistance.
• The burner flame is modulated automatically - the device is economical and efficient.
• A transition to another fuel is provided.
• The security system protects the device from emergency situations.

Elements of safety and comfortable operation

The group of automatic devices for boilers includes many elements that can be divided into two large groups: mechanisms that ensure safe operation, and devices that facilitate comfortable operation of the boiler.

The following parts are responsible for safe operation:

• thermostat;
• draft and flame control sensors;
• safety valve.

The flame control sensor consists of a thermocouple and an electromagnetic gas valve that shuts off or turns on the gas supply.

The flame temperature regulator (thermostat) maintains the required coolant temperature and also provides protection against overheating. This module turns the boiler on or off as soon as the coolant reaches a critical point (maximum or minimum).

The draft control module stops gas supply to the burner as soon as the location of the bimetallic plate changes due to increased temperature (it bends when heated, blocking the pipe through which the fuel is supplied).

We examined temperature, draft, pressure and flame sensors in more detail in this article.

In a heating system, a safety valve is an integral component of pipeline fittings, which is important in controlling the volume of coolant involved in the circuit. The hole in the valve through which gaseous fuel moves is called the seat

To turn off the device, you need to block it with a disk or piston

The hole in the valve through which gaseous fuel moves is called the seat. To turn off the device, you need to close it with a disk or piston.

Depending on the number of operating positions, gas valves can be one-, two- and three-stage, as well as modeling:

• Single-stage devices have only two operating positions: on/off.
• The two-stage device is equipped with one input and two outputs, and the valve opens when it is turned to an intermediate position, due to which the switching occurs more smoothly.
• A three-stage device is equipped with boilers that have two power levels.
• Modulating valves are used to smoothly change the power rating of devices.

Automation, used for convenience, includes options that are usually performed by users of heating systems. These include auto-ignition of the burner, self-diagnosis, selection of the optimal operating mode, and others.

Advantages

Conord gas heating appliances have the following advantages:

• boilers are very reliable and durable. They are absolutely independent of electricity, so their operation proceeds without failures or malfunctions;
• manufactured units are safe. The package includes modern automation, which is responsible for stopping the operation of the boiler in the absence of draft and other negative aspects. In addition, automatic regulation of the set temperature level is carried out and the boiler’s operability is ensured at low gas pressure;
• The performance is very high, the efficiency reaches 90%, the unit is economical. And due to the use of heat-insulating materials in the device body, heat loss is reduced;
• during operation, the unit makes virtually no noise, it is small in size and has an attractive design;
• If we compare Conord equipment with devices of other brands, we can say that the price of the equipment is quite reasonable;
• gas consumption is much less. This is due to the fact that innovative technologies were used in the process of creating burners;
• Double-circuit boilers are used not only for heating, but also to provide the premises with hot water.

Of course, Conord heating boilers have many advantages. The key ones are low price and independence from electrical energy. That is why such heating boilers can be called economy-class products. At the same time, their quality is at a high level.

Description

Boilers under the Conord brand are produced only in a floor-standing version, and they are quite large; the outside of the body is covered with a special protective enamel.

Character traits:

• the boiler is made of steel, the thickness of which is 3 mm;
• high productivity, efficiency reaches 90%;
• devices are energy-dependent;
• “nice” price will surprise buyers;
• many positive reviews.

The units related to Conord include several modifications, both with one circuit and with two. Some models are equipped with thermo-hydraulic type automatics or Sit automatics. In the first case, the operation of the boiler depends on electrical energy. The thermostat is responsible for turning the fuel supply on and off. When the temperature reaches the set point, the gas supply to the main burner is stopped and this is how the required temperature is maintained.

Such devices are well adapted to conditions of both moderate and frosty winters, since they can maintain any given temperature, provided that the power is calculated correctly. Due to high-quality installation of the burner, good productivity of the unit is achieved and an optimal gas-air mixture and thermal insulation are formed. Therefore, a large amount of heat is used to heat the coolant.

The Conord gas boiler is highly safe and has three levels of protection:

• smoke exhaust sensor, which is activated in the absence of draft. It immediately turns off the gas fuel supply to the burner. It also prevents it from being turned off in the event of short-term reverse draft during strong gusts of wind;
• the presence of a flame on the main burner is monitored. If it is not there, then gas is not supplied;
• the ability to control the temperature in the heating circuit. When the mark reaches the maximum temperature, heating of the coolant stops.

Why you need a traction sensor and how it works can be found here

Conord boilers work well in conditions of low fuel pressure. Various models may be marked KSts-G-10S or KSts-GV-12. Its meanings are as follows:

• K - boiler;
• C - made of steel;
• C - cylinder-shaped firebox;
• G - gas;
• Hot water - gas with hot water supply function.

The last numbers in the marking indicate the maximum power level of the unit.

In order to calculate the power of a boiler suitable for a particular room, you should take 1 kW per 10 m², provided that the ceiling height is within 2.5 meters and the level of heat loss is small.
