The quality of heating of the whole house depends on the health of the gas boiler, which is especially important in the cold season. Even the slightest breakdown can cause a panic attack in the owner of the equipment, since its repair can be too expensive. Agree, it is far from always necessary to call the master, because you can independently figure out the reasons for the malfunction of the Conord gas boiler, and repair the equipment with your own hands.
Despite the already established tendency to always blame the manufacturer, often breakdowns of a gas boiler have absolutely nothing to do with the specifics of production. Often they arise due to a failure in the settings of equipment, unstable pressure or voltage in the network.
Further in the article, we will tell you what breakdowns of the Conord boiler are most common, and how to independently restore its operation after another failure. In some cases, repairs may not be necessary, because to fix the problem, you just need to set the correct settings.

Causes of breakdown of gas equipment
Despite the high quality of the products of the domestic manufacturer Conord, such gas boilers may 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 breakdowns in gas boilers is a sudden shutdown or a strong surge in electricity, as a result of which the settings of the device simply go astray.
If the equipment breaks down almost immediately after installation, then this may result from an elementary failure in the settings or a voltage drop.
Often, malfunctions of gas boilers occur for the following reasons:
- Voltage drops in the network. Sudden voltage surges can lead to a short circuit, and, accordingly, a blown fuse, which will need to be replaced with a serviceable part. In this case, it is recommended to purchase quality stabilizerso you don't have to worry about power outages anymore.
- Poor quality water. In work double-circuit boilers, which are also responsible for heating water, malfunctions may occur. Heating low-quality water makes the flow-through heat exchanger unusable, so the only way out in such a situation is to install a full-fledged system for water purification.
- 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, an incorrectly executed piping of a cast-iron gas boiler can lead to the fact that at a low temperature, its body will simply crack.
In addition, weather conditions can disrupt the proper operation of gas equipment, which can cause the boiler to become unusable.
Since in frosty weather many users turn on the heating at full capacity, the pressure in the gas pipeline system decreases, which means that the boiler will simply not be able to deliver 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 a sufficient temperature inside the room
In the presence of a conventional Conord gas boiler (without heating hot water), it is recommended to install a good stabilizer, while it is better not to save on the purchase. So, you do not have to change the fuse after every power failure, and even more so, spend a lot of money to purchase a replacement for a burnt out pump.
Typical malfunctions of gas boilers Conord
A gas heating boiler is a complex and potentially dangerous system, unskilled intervention in which can provoke a large-scale explosion. All boiler systems related to the supply and combustion of gas must only be serviced by qualified gas service personnel.
Despite this, there are several individual cases in which the user can independently repair the gas boiler. This applies to visible damage and all kinds of contamination that disable the branch pipe, chimney and other parts of the boiler.
The burner does not ignite or goes out
The first thing that needs to be done after an unsuccessful attempt to ignite the Conord gas boiler is to check the draft, since it is often its absence that becomes the main obstacle.
Bring a lighted match to the viewing window and observe the direction of the flame. If it deviates towards the window, then everything is in order with the thrust, and at least one problem can be excluded.
If the flame of the match burns evenly, then this can only mean one thing - there is no draft in the chimney, which is why the burner does not ignite.
To ensure the required draft, it is recommended to slightly open the window to the boiler room. If even after this there is no draft, check the rest of the boiler for contamination. So, the presence of draft in the chimney indicates that the boiler itself is dirty, which will need to be disassembled and thoroughly cleaned. If the chimney is dirty, you will have to clean it yourself.
If, even with good draft, the boiler does not ignite, it means that a breakdown has occurred in one of the main systems of the device. For example, due to voltage drops in the network, the operation of the fan, which drives air through the entire system, can get lost. As mentioned, the best option is to install a voltage regulator.
In addition, the boiler may not work due to a malfunction. thrust sensor. If, after the first ignition of the Conord gas boiler, the flame goes out, and the repeated attempt also fails, it is worth checking the sensor and short-circuiting the terminals. And only if this does not help, the thrust sensor may need to be replaced.
The boiler smokes - what to do?
Such a malfunction can be observed in both wall-mounted and floor-standing models. If, immediately after turning on the ignition unit, soot begins to appear, this means that the air in the fuel is contained in an insufficient concentration, and it must be adjusted.
Often, the cause of the appearance of soot is the combustion of dust in the air that has settled on the surface of the burner, which means that all air channels must be cleaned with an ordinary brush.
There is only one way to eliminate the soot problem - by adjusting the air on the burner. To do this, you need to find an adjustment washer, and adjust the air supply in the desired direction without turning off the burner. It is the flame of the burner that will help you determine which way to turn the washer.
In case of excess air, there is a noticeable hum and separation of the flame from the burner, and if there is a lack of air, the red fire will be “diluted” with yellow blotches. The normal air to gas ratio is determined by an even blue flame without any impurities.
Burner flame separation
If, when starting a gas boiler, the flame is unstable, and at the same time periodically breaks off from the nozzles, then the problem is most likely in the supply of traction. Any changes in the dynamics of the flame lead to the triggering of the sensor, and, accordingly, to the shutdown of the system. In this case, it is recommended to check the chimney for contamination, and if necessary clean it.
Also, the problem of flame separation can arise due to deformation of the nozzles, which could occur during the cleaning process. It is due to the deformation of the holes that the gas flows unevenly. To restore the operation of the nozzles, and to normalize the flame, it will be necessary to replace the damaged parts.
If noticeable pops are observed during the ignition of the burner, then this means only one thing - low pressure in the line, which can only be adjusted by a gas worker
The flame can come off the burner due to elementary gas valve malfunctions, pressure sensor or diode bridge. In this case, immediately after identifying the cause of the breakdown, it is necessary to purchase a new part, and independently replace the broken element.
The coolant does not heat up
If the gas boiler does not heat the water, then the first thing to do is check and adjust the settings. If there are no further changes in the operation of the boiler, it is necessary to check the heat exchanger for the presence of scale deposited on the walls of the channels. A thick layer of plaque significantly reduces the heat transfer of the device, while the amount of fuel consumed only increases.
There is no need to buy a new heat exchanger, because the accumulated scale can be removed using special reagents. In this case, a citric acid solution is ideal, because, unlike other means, it does not affect the structure of the metal of the heat exchanger, therefore it does not damage the part. This solution is used to clean copper, brass and stainless steel appliances.
For more information on how to properly clean the heat exchanger of a gas boiler, see this material.
Ideally, the concentration of citric acid solution should be equal to 1.5%, while to remove the most difficult dirt, it is enough to heat the agent to 60 ° C
Also, the problem may lie in the operation of temperature sensors, which are out of order due to a malfunction of the automation. Having determined the breakdown, you can independently repair the Conord gas boiler yourself.
To restore the operation of the entire system, it is enough to replace the broken parts. If the boiler does not heat the water due to a blocked pump, then in this case you can unblock it yourself by setting the necessary boiler settings.
The boiler is working loudly
Over time, the operation of gas equipment may cause noise and crackling caused by a large accumulation of salts on the walls of the radiator. It is for this reason that the water overheats and boils, which is why the accompanying noise often resembles the sound of a boiling kettle.
Loud noise emanating from the Conord gas boiler may be due to the “migrating” pieces of scale, which break off during the heating of the water and hit the walls of the device. Such a process can lead to clogging of the tubes, and, therefore, to water obstruction.
In order to avoid serious consequences, it is recommended to clean the heat exchanger in a timely manner, so as not to spend money on buying a new part.
It is recommended to clean the heat exchanger in a timely manner, since the elimination of a large accumulation scale may require more aggressive chemicals that can disrupt the structure of the metal
During the operation of the boiler, there may be a noticeable whistle emanating from the nozzles, which occurs due to the accumulation of air in the line. To eliminate the problem, it is enough to release excess air from the line, and the noise will stop.
