• choose the place of the front door based on the needs - right, left;
• supply the coolant from the side convenient for it - from behind or from the side, thanks to two return lines.

Key elements:

• body;
• automation;
• heat exchanger;
• if the boiler is double-circuit, then the second circuit is also present;
• safety system.

The design consists of three parts:

1. In the lower part there is a firebox, which is closed from the lateral and rear sides with a water jacket. A heat exchanger is located above it. Thanks to the flame tubes of the heat exchanger, the efficiency of heat transfer and heat exchange between the gases that are removed and the water is achieved.
2. A smoke extractor and built-in draft stabilizer are located at the top of the structure.
3. In the middle part there is a partition, thanks to which the operation of the equipment is stable, without failures, regardless of the ambient temperature.

Thanks to the joint work of the smoke extractor and the heat exchanger, the boiler is self-sufficient, it can work without a user and does not require constant manual adjustments. Thanks to the stabilizer, even with an unstable draft, the boiler operation will be stable.

A ServiceGas burner is located in the firebox. Components - front panel, burner pipes, safety sensors - flame and draft, control unit SABK AT. Under the pipes there is a grate damper, which is responsible for supplying secondary air to the burner.

The letter designations that the Hearth boiler have are intuitive and do not make it difficult to decipher: "K" - boiler "C" - steel "G" - gas "V" - the possibility of supplying hot water (water heater coil is installed) "12.5" - boiler power in kilowatts "A" - a - possibility of operation as a solid fuel "E" - EUROSIT "C" automation - SABK-AT automation

The unit uses a gas pressure regulator to regulate the mains pressure and ensure a uniform and stable flame on the main burners without changing the thermal performance. A new heat-resistant stainless steel burner, atmospheric type is used. It is installed at the bottom of the heat exchanger, maintaining a uniform heat zone in the combustion unit. The design has a uniform placement and does not allow zonal overheating of the heat exchanger and its failure.

The built-in draft stabilizer balances the pressure at the inlet to the ejector of the main burners and at the outlet from the slotted slots. Thus, constant discharge and stable combustion of the gas-air mixture in the furnace are ensured without additional regulation.

Why does the gas boiler go out?

The fading of the flame of a gas boiler can be caused by external or internal reasons.

External reasons include:

• Reverse thrust... The most difficult case, almost impossible to eliminate by conventional means. Sometimes it helps to eliminate drafts, to open or close some doors or windows.
• Strong gust of wind outside... Cases of flame blowout by the wind are frequent, they are the result of an unsuccessfully located chimney or a low height above the roof surface.
• Drafts indoors... This situation is quite solvable, the main thing is to determine the source of the draft and close it.

Internal problems can be:

• Cut off the gas supply to the mains.
• Gas valve failure, problems with gas equipment.
• Burner nozzles clogged with soot and combustion products.

In the event of such problems, you should call the gas service and clarify the reasons for the lack of gas. The fuel supply valve must be closed before this.

Call a specialist from the service center and entrust him with the repair of gas equipment.

It is forbidden to try to repair the gas block on your own; this can cause very dangerous and even fatal consequences.

Can anyone please help solve a specific issue. The floor-standing boiler KSG 10 Hearth with SABK automatics is in operation. When you light it up, the main burner starts to burn brightly, but after 10-20 seconds it turns off. Repeated action brings no change. What could be? The first step is to check the performance of the draft sensor and thermocouple. Make a diagnosis of the circuit contacts. Carefully dismantle the pilot burner and clean. Adjust the pilot burner towards decreasing gas pressure. Most likely, the draft has decreased, and now there is not enough air for the pilot burner at the time of ignition of the main burner. The torch smokes a lot and the gas burner device burns continuously, without extinguishing. The temperature above the regulated one cannot rise, although the torch continues to burn. A lot of burning. Gas service says bad traction. What can be done? It looks like there is little air. It is imperative to perform full-fledged prevention. Disassemble the gas unit, clean and wash the burner and jets. It is recommended to clean the outside of the heat exchanger. Can you tell us what the problem is if the appliance smokes? What should be done to solve this problem? Most likely, there is a low level of draft in the combustion chamber. You should clean your chimney. How to act, tell me, when the gas boiler KSG 16 Hearth does not go on firing? I try to hold the control handle, squeeze the ignition button, then hold it for about eight minutes, release it, and the apparatus goes out. The ignition tube is likely clogged. In this situation, maintenance is required. Another problem may be oxidation of the terminals on the draft sensor. It is recommended to remove the clamps and clean them from oxidation. Problems with the boiler KSGV 23-2 e Hearth Standard with an automatic unit Minisit 710. While pressing the ignition button, there is no gas flow to the burner device. What could have happened? When you press the button, gas fuel flows only into the pilot burner, it does not flow to the main burner. You have completed the installation of this unit. I do not like the process of switching from the pilot burner to the main gas burner. It turns out two claps. It should be? We assume that it is imperative to adjust the gas pressure automation. A unit of the same model was put into operation with the Eurosit 630 automation unit, which stops when the temperature rises somewhere around seventy degrees. Please help me fix the problem? The thrust sensor may be triggered. It is imperative to inspect the chimney. The device is of the same model in operation. It had a heating failure at 40 degrees that week with the torch burning continuously. What is the reason? Most likely, the gas supply pipe from the automation unit on the gas burner device is clogged, and besides this, the burner nozzle. There is a gas boiler KSG Hearth 12.5 with automatic SABK. About three days ago, he got out a malfunction. The unit starts to go out when the wind blows on the pilot burner. Not so long ago I replaced a thermocouple, but there is no result. How to fix? When you turn on the main burner, this leads to a decrease in the flow of fuel to the pilot burner, that is, the automatic protection is activated. You need to increase the flow of fuel to the ignition mechanism.This can usually happen due to a decrease in pressure in the system. In another case, the chimney draft has weakened if it is not installed correctly. Please tell me why this device periodically turns off, mainly if there is a strong wind and bad weather outside. How should the issue be resolved? When the igniter is started, the solenoid valve is triggered in about 20 seconds. When the ignition device goes out, the EMC valve will stop working in an interval of ten seconds, 0 you will hear a clicking sound. Several years ago, I installed a KSG-10 E boiler in a private house. The house is small, about forty meters in area. It seems that the consumption is small, and the coolant cannot heat more than 55 degrees. The room has two 12-section batteries connected. I don't understand how to increase the temperature of the coolant? Installation of a circulation pump will help you. A decrease in pressure in the gas line can often occur. For what reason does the boiler overheat systematically during operation? The main source - the circulation in the heating circuit has disappeared. It is also possible that the filters are dirty or there is an excess of air in the heating system. We have a problem. If we close the cold tap and start opening the hot water supply, then water comes out of the heating circuit. What's happening? Most likely, the make-up valve of the heating system is malfunctioning. It allows water to move in both directions. If there is water pressure in the system, then there should be no reverse flow. Because of what the unit starts to make noise, gurgle, and occasionally howls for a long time and claps strongly? The water in the system is highly oxygenated. When heated, the air evaporates, causing you to hear noise. If the unit is configured incorrectly, then the gas valve or bypass valve howls. Loud bangs during start-up indicate a problem with ignition. At the end of 2014, the repairmen installed the floor-standing boiler. Hearth KSGV 16. About 3 months later, a problem arose. I adjust the temperature regime, but it does not hold it. Tell me what could be? Probably, there was a malfunction of the automation, and when the temperature rises by 65 degrees, the nozzles are turned off. It is necessary to configure the automation for the correct execution of functions. Another factor may be that the selected unmatched capacity of the unit in relation to the heated area. Completed the start-up of this unit at the beginning of August. They transferred it to liquefied gas. For 4 months, almost nine cubic meters were spent. At this time, there is an excess of soot inside the apparatus, and the burner also began to smoke. Why is this happening? Too much soot in the firebox indicates that the burner is poorly adjusted and the gas is not completely burnt. There may also be an unsatisfactory gas composition. In order to avoid soot from the burner, it is necessary to systematically wet cleaning. The same device is in operation. During start-up, the gas burner ignites and immediately goes out. I believe there is no ignition spark. How can this problem be repaired? You need to check if the sound of an ignition spark is heard when the ignition wire is disconnected. If not, you must replace the ignition transformer. If a sound appears, replace the ignition electrode or gas burner. A few days ago, a malfunction with the boiler was discovered. Hearth KSG 7. Water flows from it. He was at work no more than 3 weeks. Maybe someone will tell you why the leak occurs? Dripping can occur due to increased system pressure. Probably, the walls of the heat exchanger collapsed. Water hammer also causes leakage in boilers. In the apartment, we would like to install this device. Inform us, what is the nominal pressure for natural / liquefied gas supply for these devices? In this type of equipment, the declared gas supply pressure for methane / propane is 150/300 Pa. This device was installed for me.The other day there was a problem with him. It starts, but the house does not heat up. How can this be explained? Most likely, the accumulation of air inside the batteries or there is scale in the heat exchanger. It is necessary to rinse it. We operate this unit indoors. Until now, he worked without question. Now there is a malfunction in it. The unit goes into overheating every day. Can you help fix this accident? Most likely, there was a clogging with scale, as a result of which the duct was clogged. You must clean the device. Recently there was a problem with the heating boiler. I have been in work for a total of 3 months. Then he suddenly stopped raising the adjustable temperature. Perhaps someone will tell you what are the reasons? The system may have a gas pressure less than recommended. We need to check the gas tap. Most likely, there is a lot of grease inside. Just remove the excess. Tell me how to properly pump the expansion tank? The expansion tank is pumped up with any car pump to the pressure required according to the instructions. Typically an approximate range of 1 to 1.5 bar. To pump up the expander, it is required to drain the coolant from the boiler. This is done by means of a drain connection or using a water tap, drowning the flow to the hot water supply. Floor-standing gas boiler KSG 12 The hearth does not start. If you keep the start button pressed, the burner ignites. But if you do not fix the key, the device goes out. What is the cause of the breakdown? Probably damaged thermoelectric converter or gas valve. There may also be a decrease in gas pressure on the inlet pipes. Sometimes there is a lack of voltage on the control board. Tell me, what service work should be done in case of conversion of liquefied gas to natural gas? To do this, you need to replace the main burner nozzles. Next, change the supply voltage of the modulator. And finally, adjust the range of the highest and lowest pressure. What is the operating principle of the safety valve in the heating system? This component, which is adjusted to the required pressure, protects the heating system. Do not use the safety valve to drain water from the system. The pressure in the heating system is constantly increasing. I reduce the pressure of the expansion tank to the level of 2.1-2.3 atm. Is it possible that the heating circuit water comes from the DHW pipes? The rise in pressure in the heating system is formed by the following main factors. The pressure for the expansion vessel has not been set. The make-up tap allows water to pass through. A problem has recently occurred. The inclusion is very difficult. The pilot ignites, but the main burner has no flame. Help me figure out what is the reason? The ignition device may be defective. You need to service the device and clean the ignition mechanism. Can anyone help sort out the chimney? Soon it was three days, when the reverse draft appeared, in which the smoke penetrates directly into the kitchen. I made the chimney myself. It consists of a metal tube. Perhaps there is some inaccuracy. The main factor may be an incorrectly executed chimney design. Sometimes there is a deposit of soot on the pipe walls, which greatly weakens its efficiency. In addition, it is advisable to control the exhaust vents in the house.
