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
Conord product line
In the company’s line you will not find wall-mounted boilers, so to supply the home with heat, users prefer Conord floor-standing gas boilers, which may have various auxiliary options.
Floor-mounted units are available in four series. All units are made of durable high quality steel. To make the device more stable, its surface is coated with heat-resistant powder, which acts as protection against high temperatures and loads. Let's consider Conord heating devices from the following series:
- KSC-G-S;
- KSC-G-N;
- KSts-GV-S;
- KSts-GV-N.
Series KSts-G-S
In this series you will find a high-quality single-circuit floor-standing gas boiler Conord, which is equipped with a functional gas supply regulator. Italian automation is responsible for controlling the operation of the equipment, which makes the operation process safe, reliable and efficient.
KSC-G-S units are suitable for heating rooms with an area of 80-300 m². However, for this it is necessary to select a boiler of the correct power. To ensure that the boilers meet the requirements of the heating scheme, it is necessary to pay attention to other indicators. For example, the operating pressure of devices included in the KSts-G-S series is in the range from 0.2 to 1.9 Bar, the minimum temperature regime of the coolant is 60°C, and the maximum is 90°C.
Series KSts-G-N
The most functional boilers are produced under this marking. They are equipped with a cylindrical heat exchanger, which is made of durable cold rolled steel. Thanks to this, the device works very efficiently, heating the coolant occurs in the shortest possible time and very evenly. This series includes single-circuit boilers that are suitable for supplying heat to rooms with an area of 100 to 300 m².
Gas boiler with steel heat exchanger Conord KSts-G-N
Heating devices Conord KSts-G-N can operate in difficult operating conditions - they are designed for systems where the operating pressure reaches 5 Bar. In order for the heating process to be optimized, the boilers are equipped with high-quality thermo-hydraulic automation. The described series is considered more functional and versatile, which certainly affects the price. The cost of devices starts from 16,000 rubles.
Series KSts-GV-S
Here is a budget double-circuit gas boiler Conord. In addition to the heating circuit, the package includes another one, which is used to provide the house with hot water.
The boilers have Italian Sit automatics; they are capable of effectively heating a room with an area of 120 to 300 m². By purchasing equipment from this series, you will solve two problems at once: you will provide your home with heat and you will have a supply of hot water for household needs. Boilers are considered universal; they can be installed in any circuit.
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 .
Advantages of the furnace and heat exchanger
The cylindrical firebox withstands high pressure well, so the equipment can be used with circulation pumps. There is also no middle weld in the Conord firebox, since the product is created from a seamless pipe with walls 3 mm thick. If we remember that seams are a weak point, then their minimum actually increases the service life.
The heat exchanger is made of cold-rolled metal - it withstands thermal deformations that will certainly occur during operation. In systems with gas Conords, tap water is used as the coolant, and antifreeze is prohibited for this role.
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:
- 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.
- 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.
- 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.
Gas boilers from Conord
The Conord plant is located in Rostov-on-Don. It was founded in 1947, and since then has produced various types of heating equipment.
During its work, considerable technological experience was accumulated, the features and disadvantages of imported models of gas boilers were analyzed, and the necessary conclusions were drawn . Today Conord produces several series of gas boilers, which are the optimal solution for the Russian user.
Climatic features, the state of communications, and the possibility of interruptions in the supply of certain resources are taken into account.
The company relied on the production of units that were as independent as possible from external conditions, capable of performing assigned tasks despite the situation.
Non-volatile equipment in Russian conditions is a big plus; it guarantees the preservation of heating during a sudden power outage . This approach is reasonable and highly appreciated by specialists and ordinary users.
All Conord gas boilers have a floor-standing design. This feature allowed the manufacturer not to skimp too much on the dimensions and strength of components and parts.
There are different model lines:
- Single-circuit. Intended only for powering the heating system of the house.
- Dual-circuit. Capable of heating both coolant for heating and hot water for domestic needs (DHW systems).
Various types of automation are used in the design of boilers:
- Thermohydraulic (mechanical type).
- Automation SIT. Automatic operating mode control unit made in Italy. It has a thermostat, a piezo ignition system, an ignition burner with an electrode and a thermocouple.
There are also models with different types of heat exchanger:
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:
- 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.
- 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).
- diffuse-kenetic. Air enters two simultaneously: one is mixed with gas fuel, the second is added directly to the chamber during combustion.
Gas water heating device
The use of Italian SIT automation ensures stability of the set temperature and operation at low gas pressure.
Possibility of installing a circulation pump and operating the AOGV in a closed heating system. The cylindrical heat exchanger is made of high quality steel and can withstand high pressure.

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.
Installation rules, how to turn on a floor-standing boiler correctly
It is recommended to trust the installation, configuration and commissioning of the Conord floor-standing gas boiler to specialists from certified service centers. Only in this case can you count on the validity of the warranty period. After installation of the equipment, a corresponding entry must be made in the technical data sheet of the product.
Every year, specialists from the service center carry out a technical inspection of the boiler, which is also noted in the passport. The warranty does not apply to products whose passport does not contain these marks.
When installing a gas boiler, the following must be taken into account:
- The equipment cannot be installed on a combustible floor; it is necessary to make a backing made of fire-resistant material. The size of the substrate must exceed the dimensions of the boiler by 0.5 meters on each side.
- For normal circulation of the working medium in the system, the lower pipe of the boiler should be mounted below the heating radiators.
- The Conord gas boiler for heating a private home can be connected to pipes made of any material. However, when connecting by welding, it is recommended to make several threaded joints for possible troubleshooting.
- The riser must be strictly vertical, the deviation should not exceed 3 mm per 3 linear meters of pipe.
- According to the technical characteristics of Conord gas boilers, for free air removal, the slope of the horizontal sections should be 1 cm per linear meter.
- Branches to radiators of the heating system must be installed with a slope of at least 1 cm per linear meter.
- A shut-off valve must be installed at the coil outlet.
- The chimney for the boiler is installed in the load-bearing walls of the house.
- Sections of the chimney located in unheated rooms must be insulated.
- The diameter of the chimney should be slightly larger than the diameter of the outlet pipe. This ensures stable operation of the equipment and sufficient traction.
- It is not recommended to make chimneys with protrusions; it is best to place straight sections vertically.
- In any case, the equipment and supplied elements must comply with fire safety requirements and regulatory standards.
- Installation of a gas boiler is carried out only after agreement with special authorities.
Characteristics of Danko boilers
In the assortment you can find heating boilers "Danko" operating on gas or solid fuels. Moreover, both types are further divided into non-volatile boilers and boilers that require electricity. Each type of heating boiler differs in manufacturing materials, as well as in the design of the equipment. All of them are equipped with a micro-tile burner, capable of heating any building, and a heat exchanger made of high-quality steel. The controller regulates the correct operation of the pump, and the built-in fan maintains constant, even combustion.
Danko products include boilers with different installation methods:
- Floor-standing. They are equipped with a straight vertical chimney pipe and can be installed in any necessary room.
- Wall-mounted. These dual-circuit models are used in small houses or apartments.
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 you should entrust complex operations 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.
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%.
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)
- 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.
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.
Specifications
Let's look at the technical characteristics of Conord gas boilers:
Parameter | Meaning |
Boiler type | Gas heating |
Installation method | Floor |
Feature Set | Heating and hot water supply |
Efficiency | 90 % |
Unit power range | 8-50 kW |
Combustion chamber design | Open (atmospheric type) |
Fuel type | Natural gas |
Heat exchanger material | Stainless steel 3 mm, cast iron |
Energy consumption | Absent |
Service life declared by the manufacturer | At least 15 years |
Guarantee period | 3 years |
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:
- temperature sensor;
- igniter with thermo-bimetallic plate;
- adjusting screw with lever;
- gas valve;
- block crane;
- connecting parts.
Ignition order:
- We check the draft, move the damper, light the igniter.
- Press the gas valve and light the wick. We fix and do not release the button until the bimetallic plate heats up.
- 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.
- 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.

Review: Floor-standing single-circuit gas boiler Conord KSts-G-12N - Reliable and economical!
Advantages:
Inexpensive, works properly, economical, 3 year warranty
Flaws:
there are small ones
Gas heating has its pros and cons. On the one hand, living in an apartment, you don’t have to bother with boilers, installing them somewhere, periodically cleaning them, lighting them, etc. You wait until the heat is turned on, and that’s it. But on the other hand, they don’t always turn it on when you want. And you have to freeze without heating in the fall and spring, and sometimes, on the contrary, die from the heat. This is a huge advantage of gas heating - when you need it, you turn it on, when you don’t need it, you turn it off. We live in a private house, and we, in fact, don’t have to choose: if you want heat, install a boiler. So we installed the Conord KSts-G-12N when the previous one gave up its life.
Some technical data: overall dimensions 412/342/786, weight about 40 kg. Designed for 120 square meters (we have 100, we took it with a small margin). The efficiency is stated to be at least 90%, but how to check this? Gas consumption at nominal heating output is indicated at 1.35 cubic meters per hour. The boiler is steel, white, covered with heat-resistant powder enamel. All the “stuffing” is behind the door:
As you can see in the photo, the top cover is loose - this is not a defect in the boiler, it was after a preventive inspection and cleaning that the gas workers (!) installed it incorrectly, we didn’t notice right away, but we didn’t want to disassemble, remove the pipe and redo it ourselves, so we decided to leave it until next time . This boiler model is single-circuit; we use a gas water heater to heat water. The boiler is non-volatile, but our heating is with a circulation pump, i.e. when the power goes out, the pump does not work, the boiler overheats and automatically turns off. Fortunately, this rarely happens. There is one inconvenience during the initial ignition - you need to hold the button pressed for a while, your finger gets tired)
The instructions are the same for several models, for me personally it is not very clear, but still boilers should be installed and maintained by specialists, or at least technically competent people, this is not about me:
The boiler does not, of course, have all sorts of useful and pleasant functions such as programmable switching on at a certain time and the like, like its more expensive counterparts. But the manufacturer gave a 3-year warranty, and the promised service life is at least 15 years. The boiler was installed in the summer of 2010 and survived 2 winters. It was not very warm at home only in the most severe frosts of 30 degrees. In general, everything is fine so far, only this spring, however, it unexpectedly began to smoke, I had to urgently clean it (I confess, it was cleaned for the first time, although it needs to be at least once a year). It is more economical compared to the previous boiler, heating a 2-storey house with an area of 100 sq. m., an average of 500 cubic meters per month is consumed (naturally, more in winter, much less in summer, but I’m used to paying one amount all year round, it’s more convenient for me). PS Unfortunately, we have to add a fly in the ointment to the previous positive impression. Today it suddenly started smoking again, 9 months have passed since the previous cleaning. So, during cleaning, specialists removed one of the turbulators and discovered that it had burned out in one place. After less than 3 years of work.
Use time: 2 years
Cost: 9600 rub.
Year of manufacture/purchase:2010
General impression

The reliability of these popular devices is guaranteed by the increased level of durability of heating devices, and their independence from electricity will allow them to function without any failures or delays, especially in conditions where there is no electricity.
The low level of noise impact during operation, compact size and stylish design will allow you to place the device in the kitchen or any other room without harming the design of this room.
A gas unit with 2 circuits from Conord can heat the room as quickly as possible, and also provide home owners with heated water for personal needs.
The safe operation of the products is guaranteed by the arrangement of various protection components of the automation box, which will help turn off the product when the traction is lost. 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.
Description of some models
The Conrod range of gas boilers is represented by several main models:
- KSts-G-S is a single-circuit type boiler equipped with SIT automation. The power of the unit varies from 8 to 30 kW. Water can heat up to 60-90 degrees, operating pressure can range from 0.2 to 1.9 bar.
- KSts-G-N is also a single-circuit type model, but with thermo-hydraulic automation. The boilers are produced with a power from 10 to 30 kW; cold rolled steel was used to manufacture the cylindrical heat exchanger.
- KSts-GV-S is a two-circuit type unit with SIT automation and a power of at least 12 kW. The boiler fully functions when connected to a system with natural and forced circulation.
- KSts-GV-N is a double-circuit model of gas boilers, equipped with thermo-hydraulic automatics. The boiler power ranges from 12 to 30 kW. There is a function to turn off the gas in the absence of traction. With a short-term reverse thrust, the device normalizes operation.
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.
Advantages of the Conord steel boiler
- Larger selection of models.
- Steel boilers are more convenient to maintain. The heat exchanger, for example, is easier to clean. Since steel does not crack from impacts, this greatly facilitates the activities associated with removing carbon deposits. Maintenance and cleaning must be carried out regularly, otherwise the Conord boiler loses its high efficiency indicators.
- Steel boilers are impact-resistant structures, so you don’t have to worry about damage during transportation.
- The maintainability of a steel Conord boiler is much better than a cast iron boiler. Possible “burnouts” are brewed on the spot, of course in the case of a minor nature.
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.
How to adjust draft in a gas boiler?
How to adjust the draft in a kazan boiler?
After setting up a gas boiler from Bosch or another manufacturer, the draft may weaken. It is sometimes necessary to check it both in the equipment itself and in the pipe. Look through the window, clear the paths of soot. Weather can also affect traction.
The deflector helps improve traction. It artificially lowers blood pressure. Or you can buy a fan, weather vane.
The gate is installed when the thrust, on the contrary, is too strong. And then the chimney cools down, becoming covered with condensation from the inside. The pipe becomes clogged with soot or ice. But you just need to remember to turn the draft regulator once every few days so that the equipment does not deteriorate, otherwise you won’t be able to change the position later.
If you are setting up a Navien or other gas boiler and choosing a damper, then take into account the length and height of the pipe. The diameter of the regulator must be smaller than the diameter of the pipe.
There are mechanical regulators. They are suitable for solid fuel equipment. But the craftsmen also use gas ones.
Instructions for setting up the damper for a gas boiler:
- Empty the boiler.
- Remove the coolant (if the heating cannot be turned off using taps).
- Place a gate valve in place of the plug.
- Return the coolant.
- Light the burners.
- Set the degrees.
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.
Pressure testing and washing
Pressure testing of the system is not the most necessary preparatory stage, but it is desirable, since it will show defects and leaks in advance, if any. Pressure testing is not always done due to the lack of a special pump and the reluctance to call a team, but if the heating fails in the midst of cold weather, the costs can be much higher!
It is especially important to check a new system and one that, on the contrary, has been in use for several years. The cost of crimping in construction companies is from 3000 rubles
Additionally, they may charge a fee for visiting the site (about 2 thousand rubles). By the way, a manual pressure testing pump will cost 4.5 – 6 thousand rubles

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.
Peculiarities
The Conord brand represents gas boilers only of the floor-standing type, so each model has a fairly large size and a casing protected by special enamel.
The characteristics of the Conord gas boiler for heating can be given according to the following descriptions:
- The use of steel 3 millimeters thick for the manufacture of the boiler.
- The efficiency of the device is about 90%.
- The need to connect to the power supply network.
- Reasonable price.
- Positive consumer reviews.
The Conord gas boiler is available in several modifications. For example, with or without hot water preparation. The units can also have SIT automatics or thermo-hydraulic automatics. For the second type of boiler, a power supply is required; a thermostat is responsible for supplying and turning off fuel. When certain temperature values are reached, the gas supply to the main burner is stopped, which allows maintaining the required temperature. It doesn’t hurt to know how a gas heating boiler works in order to appreciate the advantages of this equipment.
The Conord gas heating boiler can operate in any conditions, including cold winter. Correct calculation of power allows you to maintain the set temperature regime. A high-quality burner installation increases boiler productivity by creating an optimal gas-air mixture and thermal insulation. This makes it possible to direct a large amount of thermal energy to heat the working environment.
The safety of the Conord gas boiler is ensured by several levels of protection:
- Smoke sensor. This device turns off the gas supply to the burner in the absence of draft. In addition, the sensor prevents the burner from switching off during short-term reverse draft from a strong gust of wind (about
Removing air pockets before lighting a gas boiler
Air vents must be installed in the upper fitting of each radiator. These can be Mayevsky taps, or automatic valves.
The automation will handle everything itself, you just need to give it a little time (the fact that the air has escaped will be indicated by a drop in pressure).
To bleed air using a Mayevsky crane, you need to prepare a bucket, a rag, and a special key from the installation kit (or a screwdriver and pliers).
A container is placed on each radiator one by one, the tap is unscrewed, and the air hisses out. Then the battery will begin to “spit” air mixed with water. You can close the air vent when a trickle of water flows from it.
Approximately 5-7 minutes for each radiator - and the first air pockets are removed. The pressure gauge readings are checked (they should drop) and the water tap is turned on again. It would be good to repeat the air release procedure again.
Ultimately, the pressure should be above average, but not maximum, because when the water heats up, the pressure will increase further.
Turning on the boiler
- The gas boiler is plugged into an outlet.
- The switch must be set to zero.
- The gas supply is turned on (the tap on the gas pipe is opened).
Further actions may differ for different models of gas boilers.
For example, the switch for Aton or Danko boilers needs to be set to the “star” icon, press the entire switch and hold it for 5-10 seconds.
Then, without releasing the switch, press the button located nearby.
The unit will respond with a characteristic click and hum. After which the regulator is released and the required power is set.
To turn on the Baxi boiler, you also need to turn on the gas, plug in the plug and press the “Start” button. The operating sound will appear. You need to give the device a little time, and it will automatically ignite the flame. After that, you need to press the power button again and connect the heating circuit (the corresponding icon will appear on the display). Finally, using the buttons, the desired temperature is set.
Heating appliances of the Buderus brand are characterized by high reliability. Buderus gas boiler - a brief overview of popular models and their cost.

To organize a full-fledged heating system in a private house, it is necessary to install a boiler. The article https://microklimat.pro/otopitelnoe-oborudovanie/kotly/kak-vybrat-dlya-chastnogo-doma.html discusses the main criteria for choosing heating equipment.
Advantages of Conord boilers:
- The manufacturer promises more heat for less money;
- Gas consumption ranges from 0.44 to 2.74 for the steel version and from 1.99 to 4.8 m3/h for the cast iron version. A significant reduction was achieved by using innovative technologies in the creation of modulation burners;
- Straight lines – laconic design;
- Cost-effectiveness is determined, among other things, by good thermal insulation;
- Efficiency from 90% in steel to 92% in cast iron;
- Two types of automation;
- Security has a multi-level basis. The draft sensor in the design of the smoke collector instantly shuts off the flow of gas in the absence of natural smoke removal. The overturning of the draft, in the event of a discharge during a strong gust of wind, will not disrupt the stable operation of the Conord boiler if this phenomenon is of a short-term nature;
- Low noise performance.
- During the warm summer period, you can use only the second circuit without using the heating circuit. That is, the boiler works like a gas water heater in summer;
- Application of multi-layer protection on the cladding: zinc coating, followed by a layer of polymer included in the paint and a film of synthetic material completes the “pie”;
- Functionality: installed in both open and closed heating systems;
- Optimal ratio of cost and quality;
- The Conord boiler has successfully passed tests in accordance with Russian standards;
- Certified line of equipment.
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:
Solved: Conord boiler does not regulate water temperature
Gas burner device AGU-T-M, I ignite it, bring the temperature to, for example, 70 degrees, turn the regulator clockwise until the combustion starts to decrease, but the burner continues to burn at 80 and at 90, and so on until the water boils, if you turn it a little counterclockwise, the burner goes out and won't turn on until it reaches room temperature. Those. no automatic regulation. I disassembled the block tap (if I call it correctly), there was dried grease in it, washed it, lubricated it with graphite, but it didn’t help, it looks like the temperature sensor is faulty. Who is “in the know”, tell me, is there a possibility of checking it?, Repairing it? What's in it? Kerosene? If anyone has it, please share the drawing of this automation unit.

Diagnostics of gas boilers
As a rule, most modern gas boilers have an internal diagnostic system that independently detects any malfunction and displays its code on a digital display. Since each model has its own codes, they are not listed here, but in the corresponding forum topics
From the error codes, the technician identifies the most likely cause of the failure. However, some defects are not detected by the processor (controller) in error codes; they require detailed manual measurements or adjustment of equipment components. Based on the diagnostic results, you may need:
- Replacing individual components
- Replacing the board assembly
- Replacement of units
- Setting up nodes

Recommendations
Despite the fact that Danko boilers have a long service life and reliability, some breakdowns still occur.
Therefore, all owners of gas equipment should know the main types of malfunctions and the causes of their occurrence.
- The formation of soot and soot on the internal surfaces of the boiler indicates problems with the chimney. In this case, you should clean the pipe from accumulated combustion products and wash the parts of the device from dirt.
- Unstable operation of the device and temperature fluctuations in the system indicate a malfunction of the fan or circulation pump. If you have the necessary spare parts, you can repair the device yourself.
- If the boiler's pilot light goes out or the wick does not light, the reason is most likely the absence of a special valve in the chimney system that prevents backdraft. The igniter going out may also be due to the thermostat tripping. In this case, adjustment of the device is necessary, which should be done by experienced specialists. Only single-circuit boilers are subject to attenuation. In dual-circuit devices, such problems are not observed.
- If the combustion sensor or pipe fails, the device is urgently disconnected from the gas supply and left to cool. Repairs can only be performed when the breakdown is not related to a fuel leak. For example, cleaning the pipe can be done independently, but more serious faults should only be trusted to a specialist.
- Increased fuel consumption and the presence of extraneous noise before attenuation are most likely caused by a failure of the controller. If you have the necessary spare parts, you can repair the part yourself.
In the next video you will find a review of the Danko 12.5 TN solid fuel boiler.
Autonomous heating systems for private houses are gradually becoming no less common than centralized networks.
This is caused by the desire to save on paying for network resources, the unavailability of connecting to a central heating center in remote cottage villages, or other reasons.
There are a large number of samples of heating devices on the market, of which gas boilers are unanimously recognized as the most effective.
They are produced by all well-known companies in Europe and Southeast Asia.
Manufacturers from the countries of the former USSR are not lagging behind, their products are able to successfully compete with European models.
