Possible breakdowns, repair methods and settings for the Keber boiler

Pressing and rinsing

Pressure testing is not always done, due to the lack of a special pump and 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 the new system and the one that, on the contrary, has been serving for several years. The cost of crimping in construction companies from 3000 rubles

Additionally, they can take a fee for leaving the facility (about 2 thousand rubles). By the way, a manual pressure test pump will cost 4.5-6 thousand rubles.

Specifications and device

Keber boilers are distinguished by reliable assembly and long service life. The manufacturer gives a 15-year warranty. Also, the units of this brand are characterized by high efficiency.

The complete set of the Keber gas boiler device includes, thanks to which it is provided:

• stable heating of the coolant;
• the most complete combustion of fuel.

In addition, these elements are distinguished by high anti-corrosion properties.

Due to the fact that Keber boilers have gas burners, the size of their fuel chambers is smaller than that of similar heating devices manufactured by other manufacturers. Thanks to the special design of the Danko automatic equipment, the fuel burns as efficiently as possible, even if the flame height reaches 7 cm.

Also included in the package is the Arbat automation, which is responsible for regulating the operation of heating equipment and its safety. There are five levels of protection. When the pressure in the water or gas supply system drops, the unit will turn off on its own. The design of the automation is simple, which has a positive effect on its reliability, and in the event of a malfunction, the repair will be simple.

It is worth saying that, if desired, users can order a model from the Keber boiler manufacturer with a more expensive, but at the same time more reliable and high-quality Italian Eurosit automation. Such units can operate practically without third-party intervention.

The assortment of the company that produces Keber boilers includes a wide selection of models of different capacities: 10, 12.5, 16, 20 kW, etc.

Consider the technical characteristics of the device using the example of the Keber 12.5 floor model:

• type of execution - floor;
• combustion chamber - open;
• power - 12.5 kW;
• Efficiency - from 85%;
• mechanical control;
• - 1.62 m³;
• weight - 39 kg;
• heated area - 125²;
• the maximum water pressure in the heating system is 3 bar.

Insufficient pipe diameter or narrowed section

When choosing a pipe diameter, several parameters must be taken into account:

• pressure in the system (with low pressure, pipes of a larger diameter are required);
• area of ​​the heated room and boiler power;
• pipe length (for a longer system, larger pipes are required);
• the number of turns in the system (a large number of turns affects the speed of passage of the coolant, in this case, pipes with a margin in diameter are also chosen);
• number of consumption points;
• the required level of water heating;
• pump parameters.

The pipe diameter is determined primarily by taking into account special calculations. For this, a special table is used to calculate the throughput of pipes. If the boiler is powerful, a large diameter pipe is required.

Only a specialist can accurately and accurately determine the diameter of the pipe section so that the system works properly and as efficiently as possible. However, you yourself can identify the approximate range of the permissible section using simple calculations.

So, based on the average speed of movement of the coolant equal to 0.02 km / s, it can be calculated that a pipe with a diameter of 25 mm will be required to ensure a throughput of 30 l / s, and 32 mm to ensure a throughput of 50 l / s. When calculating, depending on the length of the system, for a length of less than 10 meters, pipes with a cross section of 20 mm are used, for a length of 30 meters - with a cross section of 25 mm, for a length of 35 or more meters - 32 mm, etc.

Even if the main pipe through which the coolant passes has a suitable diameter, but there is a narrowing in some area, the throughput will decrease in the entire system and this will serve as an obstacle to reaching the desired temperature.

Features of the

The ATEM brand has invested all its efforts in the development and production of a high-quality device for autonomous heating. For more than 27 years the company has been giving heat to its consumers in the form of Zhitomir gas boilers. Since the appearance of the first boiler, a huge rebranding has been made, the device has received changes from an internal base of spare parts to an external design. Today the Zhytomyr boiler is a neat block of small dimensions with switching instructions that even a child can handle. The main quality inherent in boilers of this brand is the quality and reliability of the device. Product specifications have also changed with the advent of new technologies. Not only these components, but also many other facts allowed the ATEM brand to get the European Quality award.

About the manufacturer

Since 2006, Keber gas boilers have been produced domestically, which is part of the Tactical Missile Armament OJSC corporation. These heating devices are well adapted to the Russian operating conditions; they function smoothly even in places with very low temperatures.

If necessary, such heating devices can be used for space heating in the Far North.

The Keber assortment includes both household and industrial models.

Single-circuit and double-circuit units are distinguished. The former are used exclusively for heating, while the others provide the room not only with heat, but also with hot water.

Technical parameters of gas boilers Atem

Atem produces:

• floor gas boilers Zhitomir;
• wall devices ().

Units with installation on the floor are further subdivided into single-circuit and double-circuit. Devices with two circuits can heat water for two or three consumers with low consumption. See the technical characteristics of all floor-standing gas boilers Zhytomyr in aggregate.

The capacity for the hot water supply of floor-standing installations with two lines is from 175 to 1400 l / h with a temperature difference of the heated liquid of 35 ° C. The device can be equipped with a circulation pump, which is installed as a function. Parameters of the model range of double-circuit gas boilers Zhitomir of the parapet type in the table.

Parapet 2-circuit units provide warm water flow from 160 to 345 l / h at a temperature difference of 35 ° C.

From the tables, we can conclude and make sure that the wall-mounted and floor-standing boilers of this manufacturer are adapted to the conditions of low gas pressure in the pipelines, and this is their huge plus. A weighty minus is the maximum pressure of the heat carrier in the heat exchanger, which is possibly quite low. For boilers mounted on the floor, this is up to 2 kgf / m², and for hinged boilers - up to 0.7 kgf / m².While imported counterparts can operate at a system pressure of up to 3 kgf / m². Therefore, you can make sure that the equipment from Atem gas is more adapted to gravity systems and small houses with one or two floors.

Experts do not recommend buying wall-mounted devices for 2-storey cottage buildings, since there will simply be little pressure for high-quality operation of the pressure system.

Design features

The main elements of the Zhytomyr boiler are:

• the case in which the main components and equipment are installed;
• gas burner block located in the firebox. Here the combustion of gas and the release of heat flow occurs;
• recuperative heat exchanger, in which heat exchange takes place between the combustion products and the coolant;
• flue gas system, its duties include the removal of combustion products outside the boiler and discharge into the chimney.

In order to increase the efficiency of heat exchange, the gas boiler Atem Zhitomir 3 has the following design features.

1. Heat exchanger pipes made of heat-resistant steel have a rectangular cross-section, such a device allows you to increase the contact area of ​​the flue gas and the coolant.
2. The counter movement of coolants was organized, this solution made it possible to increase the efficiency of the heat exchanger up to 92%;
3. To increase the area of ​​interaction between the combustion products and the coolant, as well as to prevent the accumulation of soot on the surface of the steel pipes of the ATEM boiler heat exchanger, turbulators are installed. Soot accumulates on the underside of the turbolators, keeping the pipe walls clean. To remove soot, periodically remove the turbolators and clean them of soot.
4. Gas double-circuit turbocharged boilers in Zhitomir have a coil of copper pipelines around the heat exchange heating pipes.

The POLIDORO gas burner device is used to organize a stable gas combustion process. Its distinguishing feature is a single stage atmospheric burner. The edges of the burners themselves are made of heat-resistant steel, which allows maintaining the combustion mode with different gas supply to the furnace. Even at low gas flow rates, the heating of the edges is sufficient to maintain a stable combustion.

The gas supply mode is regulated by the EUROSIT gas valve. This device automatically switches the gas supply to the burners, depending on the temperature of the coolant. The user independently sets the temperature of the coolant, focusing on the temperature in the open air. With a decrease in the ambient temperature, the temperature of the coolant rises.

The boiler does not light up

If the gas boiler does not thrive, then in most cases there will be an error signal on the information panel indicating its number or code, by which you can roughly find out in which boiler system the malfunction occurred and how critical it is. All double-circuit boilers provide for switching between summer and winter operating modes. In summer mode, the boiler will not turn on to heat the room (the same is true when using weather-compensated automation or thermostats).

If the boiler does not ignite and does not make any attempts to turn on (idle), when necessary, this may be an electronics malfunction, but such cases are rare and concern specific models of boilers.

Usually, if there is a malfunction that prevents the boiler from working properly, the user will receive an error. That is, if the boiler does not ignite, you need to determine the error code and find its meaning in the equipment operation manual. Error codes with descriptions are always indicated there.

Next, we will consider the most common boiler malfunctions that users encounter. It is worth making a reservation here that mainly all modern boilers have the same basic structure and operating procedure.Nevertheless, to solve a specific problem on a specific boiler, you must at least familiarize yourself with the instructions for this boiler.

Several unsuccessful ignition attempts

This is the very first error code for most hardware manufacturers. For BAXI E01 boilers, for Arison 501 boilers, for Vaillant F28. Ignition of the gas-air mixture in the combustion chamber will occur under two conditions: the presence of gas at the burner nozzles and the presence of a spark. Gas enters the burner through the gas valve, the spark is generated by a transformer on the control board (or remote). A separate case should be noted the situation when ignition occurs, but the boiler cannot detect the presence of a flame and goes out (closes the gas supply valve).

The most common reasons are:

Phasing error

... Often, gas boiler boards require that the polarity of the connection be observed. For the average user, this means that the position of the plug in the outlet matters. If the polarity of the connection is violated, the boiler does not see the presence of a flame, continues to ignite (crackle of the electrode) even when there is already a flame on the burner, then it turns off in an emergency. Even if you did not touch the plug, the polarity could change at the substation!

Ignition or flame ionization electrode

... It can be separate or combined. The main problems can be associated with contamination (oxidation) of the electrode or its gap relative to the torch. A dirty ionization electrode prevents the board from detecting the presence of a flame and the operation stops.

High voltage wire. The high voltage is generated by a transformer and is transmitted through a wire to the electrode, where it breaks down the air gap between the torch and the electrode with a spark. If a characteristic crackle is heard, but the spark on the burner is not visually visible, it is possible that the breakdown occurs somewhere else. For example, there is a microcrack in the insulation of a high-voltage wire, and a breakdown occurs at the point of insulation failure on the case.

Electrical connection problems

... The presence of parasitic potentials on the boiler body, lack of grounding or low supply voltage can cause problems with ignition. I often hear the argument: before, everything worked without grounding. No one will understand how the boiler worked without grounding. It must be followed according to the operating instructions! For normal operation of the boiler, there must be: the mains voltage is at least 180 volts, the potential between the neutral and earth wires is up to 10 Volts, the presence of grounding.

No gas on the burner

... The gas valve controls the gas supply to the burner: it opens and modulates (gas dosing). The gas valves are regulated and controlled by the control board. Accordingly, the cause of problems may be a malfunction of the valve (or the need for adjustment), its electrical part or the control circuit on the board. The inspection of this device must be entrusted to a specialist. The lack of gas can also be due to external factors: meter malfunction, dirty filters.

Control board.

In some cases, the lack of ignition or flame control is caused by a malfunction of the boiler main board. This can be considered after the other possible causes, which are described above, have been verified.

Insufficient draft (the fan does not turn on)

Also a popular problem. If there is a problem with the removal of combustion products, the boiler will not start and will ignite until it is completely eliminated. Such malfunctions and their solutions are described in more detail in a separate article - chimney errors.

Insufficient water pressure (make-up required)

Traditional gas boilers operate in a closed heating system, respectively, so that the boiler does not turn into a hydrogen bomb, there must be a minimum water pressure inside the heat exchanger (in fact, the presence of water and circulation there). The pressure is controlled by a special sensor - a pressure sensor.An additional mechanical pressure gauge is provided for the user in the boilers. Although the systems are closed, the pressure in them can drop over time (for example, water leaves through leaks in the connections). As soon as the water pressure in the boiler falls below the minimum level (0.5 - 0.7 bar), the boiler sensor detects a malfunction and blocks operation. In most cases, you just need to study the readings of a mechanical pressure gauge and recharge the system according to the instructions for the boiler.

Moving on to cleaning the column

We turn off the gas supply valve to the boiler. Using the key No. 10, unscrew the fastening screw under the boiler door and remove the door.

Disconnect the wire connecting the piezoelectric element and the ignition electrode.

Unscrew the thermocouple clamp with the key # 10. Unscrew the thermocouple from the valve with the key No. 9.

Note:

it is necessary to ensure that the thermocouple does not rotate during unscrewing.

We mark the depth of entry of the nozzle into the main burner so as not to disturb the boiler setting.

Using the No. 17 wrench, unscrew the nut securing the copper tube from the burner to the valve. Using the key # 10, unscrew the ignition electrode from the pilot burner and the copper tube from the pilot burner and valve. Using a flat-head screwdriver, unscrew the two screws securing the pilot burner.

The gasket installed under the pilot burner has deteriorated. It will need to be replaced.

We remove the nozzle from the pilot burner.

Tip: If the nozzle is stuck, you can lightly tap the burner with a wrench.

Unscrew the four screws securing the main burner to the boiler body and the screw that secures the body in order to be able to remove the main burner.

Lowering the main burner down, remove the copper tube from the valve.

We remove the main burner.

We take out the thermometer sleeve from the boiler body.

Using the key No. 10, unscrew the four screws securing the upper boiler cover and remove it and the insulation sheet under it.

We unscrew the two nuts securing the flue to the boiler body.

We remove the terminals from the draft sensor.

We remove the gas duct.

We remove the swirlers from the boiler heat exchanger. We clean them with a brush. If necessary, use a metal brush.

We clean the outside of the heat exchanger with a metal brush. We clean the channels of the heat exchanger with a brush to the full depth. We clean the bottom of the heat exchanger with a brush. We also clean the gap between the boiler body and the floor. We clean the exfoliated debris with a vacuum cleaner.

Release the screw fixing the depth of entry of the nozzle into the main burner with the key No. 13 and remove it.

We clean the burner with a brush and a brush, clean its holes with a vacuum cleaner. We clean the flue from dust outside and inside.

We clean the outer surface of the nozzle with a brush, then clean the nozzle holes with a needle or wire.

Note: the needle must be of a smaller diameter than the diameter of the nozzle orifice. Even a slight increase in the diameter of the nozzle orifice can affect the combustion mode.

We install the main burner in place.

We install the copper pipe with the nozzle and screw its nut onto the gas valve.

Only after that we fix the nozzle on the burner at the mark with the key No. 13.

Note:

this sequence is necessary in order not to strip the threads in the valve body.

Finally, we clamp the nut of the copper tube with a wrench No. 17.

We clean the pilot burner with a metal brush.

This is how the thermocouple must be installed in the pilot burner (tip of the thermocouple against the flame tongue).

Install the pilot burner on a new gasket.

Before installing the nozzle in the pilot burner, it must be rubbed a little against the tip of the copper tube for a better seal. The nozzle should also be cleaned or blown out.

Connect the copper tube to the pilot burner and to the valve with a # 10 wrench.

The rest of the boiler parts are assembled in the reverse order. When connecting, the ignition electrode should not be clamped with a key; it is enough to do it by hand, since it is made of ceramic and can easily crack.

We carry out control soaping of all compounds. It is possible to check the tightness of the connection of copper pipes to the main and pilot burners only when the boiler is turned on.

Closed turbocharged equipment malfunctions

Sometimes, when installing a new smokeless appliance, the flame periodically decays. In this case, you need to check the nodes and parts. The problem is identified by the following factors:

ignition of the igniter is accompanied by periodic attenuation - this indicates a failure of the thermocouple, which affects the actuation of the valve. It is produced in the form of a copper tube with a bimetallic piece at the end. When various metals come into contact, the voltage rises to 20-45 W. This problem keeps the gas valve open. The thermocouple must be replaced with a new one; it cannot be repaired;

• breakage or clogging of the draft sensor - the flat part is combined with the fuel valve. When the leading contacts close and the burner ignites, a fire occurs - this indicates the need to replace the sensor. Oxidized contact areas can be cleaned with sandpaper with fine abrasives;
• in the event of a malfunction of the circulation pump, it is necessary to carry out a complete diagnosis of the unit and its replacement;
• a yellow flame is due to a clogged jet. You can clean it if you have experience with gas appliances.

Most of the reasons can be eliminated with your own hands, however, this will require some knowledge and a lot of time.

Rules for filling the system with water before turning on the gas boiler

Before igniting the gas boiler and turning on the heating system, first it is filled with cold coolant, which, after heating, will circulate through pipes and radiators. During the first launch, everything is carefully checked so that the work in the future is uninterrupted, and the equipment does not require repair.

These pressure parameters can be changed, since they depend on the manufacturer's requirements for the operating pressure in the heating system. But the filling with cold water does not finally end there, since recharge will be required after the structure has been freed from air jams.

Leakage in systems with automatic make-up

This reason applies to powerful industrial boilers or private systems with automatic make-up. Automatic make-up is a kind of safety device that takes effect when the pressure in the system drops. In the event of a water leak (for example, when a pipe breaks underground), the automatic system begins to constantly add more and more water. With an intense leak, the volumes of water will be significantly increased, and the boiler will not be able to reach the desired temperature. At the same time, due to the constant flow of cold water into the boiler, the device will not turn off.

Removing air pockets before igniting the gas boiler

Before igniting the gas boiler, you need to fill the heating structure with cold liquid heat carrier. But filling with water alone is not enough. It will either not work, or the degree of heating of the room will be insufficient. A full-fledged first start is impossible without bleeding the air accumulated in the system. Often, modern gas boilers have a special system that automatically releases air when filled. But often its effectiveness is insufficient: you will still need to manually reset air jams. Only then can the launch be carried out.

It is necessary to remove air plugs before turning on the gas boiler not only from the heating unit, circulation pump, but also from all heating radiators.The process should start with batteries - for this, as mentioned above, they are equipped with Mayevsky cranes. They are opened by substituting a container from below. There will be a slight whistle at first, indicating that air is gradually escaping from the system. After removing the plugs, water begins to flow. Then the taps are closed. A similar procedure should be done with each of the radiators. "How to choose a Danko boiler - types of heating gas boilers, features, advantages."

When the air from the batteries is removed, the gauge needle should settle at a certain value. Before igniting the gas boiler, the heating medium should be added to the system and thus fed. "How to turn on the Lemax boiler - operating rules."

Heating circuit problems

The pump must be matched to the requirements of the heating circuit.

Malfunctions in the operating mode of the heating circuit are not always associated with a malfunction of the main heating element. If the boiler works, but does not heat the batteries, the reason must be sought in the wiring itself.

A list of the main malfunctions of the heating circuit:

• the filter on the return line or the needle valve (Mayevsky's valve) is clogged;
• insufficient power of the circulation pump;
• the rules for installing the natural circulation heating circuit have not been followed.

Any of the above problems should be resolved before the start of the heating season. Otherwise, the room may remain without heat for several days, since the repair provides for a complete drain of the coolant.

So, why does the boiler not heat up the batteries, if during the previous years everything worked normally? The reason is a mud plug, which has formed on the heating circuit filter and completely blocks the coolant flow. It is solved simply - the water is drained from the pipes or, with the help of bypasses, its circulation is shut off, the filter is cleaned. To prevent a repetition of such a situation, it is necessary to completely replace the coolant with parallel flushing of the entire circuit.

In a gravity system, the slope of the pipes is of key importance.

The second reason why the boiler works, and the batteries are cold, is the insufficient power of the circulation pump. The performance of the device is not enough to timely and efficiently pump the entire volume of the coolant. Or, in the house, the heating system has branches that are at a significant distance from the pump. As a result, the circulating pump overheats, the heating equipment operates with excessive consumption of the energy carrier, and the radiators remain cold. The solution is to replace the coolant pumping device with a more powerful one.

If the house has a two-pipe heating circuit with natural circulation of water, and during the heating season it is often noticed that the boiler is on and the batteries are cold, then the reason lies in the failure to comply with the slope of the line. According to regulatory documents, only a pipe slope of 10 mm for each running meter in a natural circulation heating system will ensure the normal movement of the coolant. As a result, the batteries warm up evenly throughout the house. If there is no slope, the coolant stagnates, which negatively affects the temperature of the radiators. You can solve the problem by completely redoing the wiring.

What liquid for cleaning heating systems to choose? The selection criteria are described here.

Varieties

To date, several types are involved in the production of Zhytomyr boilers - parapet (wall) and floor. In turn, floor products also have subdivisions for single-circuit and double-circuit.

Floor standing

If a gas boiler is needed only for heating purposes, attention should be paid to single-circuit models. They are unpretentious, practical and economical.

Equipping a single-circuit boiler "Zhitomir" primarily implies imported components.Thanks to them, the device can be turned on and off, if necessary. And if there is a need, in addition to heating, to have hot water in direct access, you will need to choose from two-circuit options.

In terms of their technical characteristics, floor standing boilers mostly have such similarities as:

• the maximum temperature limit is +90 degrees;
• efficiency is 92%;
• gas pressure - 635 Pa.

But already when choosing a model you definitely like, you need to consider its specific characteristics and capabilities.

Wall mounted

The same division as for floor-standing boilers is also present in wall-mounted boilers. They can also be single-circuit and double-circuit. The efficiency is the same for all devices. The same goes for gas pressure.

But still it is worth considering their characteristics p>

• the power of parapet boilers must be at least 5 kW and no more than 20 kW;
• the coolant in the device is no more than 17.5 liters;
• depending on the chosen model, the consumption of natural gas is considered; according to the standard - 0.56-1.67 cubic meters per hour;
• profitability due to imported automation.

For its part, the manufacturer provides a wide range of boilers to choose from, but still the model "Zhitomir-3 KS-G-020 SN" is in great demand. This device differs from its counterparts not only in terms of affordability in terms of the price factor, but also has clear technical data. The design of the device is designed in a minimalist style; the boiler looks like a cabinet. It should only be placed on the floor. On the front of the model there is a small door, behind which is a button for turning on and adjusting the settings of the device. In the same part there is a control window, with the help of which it is necessary to monitor the performance indicators of the boiler.

The basic configuration includes a casing, which also includes heat exchanger elements. Outside, it is covered with thermal insulation material and a casing made of steel. The burners are presented in the amount of two pieces: one is the main one, and the second is the ignition one. The package includes a gas duct and an automatic gas valve, which is responsible for safety during operation.

Methods for eliminating the causes of shutdown of units

Incorrect unit power

If the gas boiler is often turned on and off, then this indicates that the power of the unit is too large for this room. As a result, the device quickly picks up the desired temperature and turns off. Frequent switching on and off lead to increased wear of the boiler parts.

Therefore, before buying a gas device, it is important to calculate the optimal indicator of its power based on the area of ​​the heated room, its insulation and other factors.

For a large private house, floor-standing gas boilers with a capacity of 35 kW or more are suitable. For apartments and small cottages, it is better to purchase compact wall-mounted models that fit perfectly into a small kitchen or hallway.

If the boiler is already installed, then the problem of overpower can be solved by the following methods:

• installation of four-way valves;
• readjustment of the gas burner to the minimum mode;
• connecting a boiler or other systems so that part of the boiler's power is spent on them.

Low line pressure

Typically, the reasons for low gas pressure are the following factors:

1. Fuel meter problems. Suspicious sounds or noise may be emitted from the device. On a faulty device, the readings change in jerks or the arrow does not move at all. To fix the problem, contact a specialist.
2. Safety sensors have triggered - if the system has noticed a fuel leak, then the unit is blocked. The leak also smells like gas. If such a problem occurs, you should turn off the gas boiler and call the gas service master.
3. The filter is clogged - it should be cleaned.

Reverse thrust

If there is a reverse draft and the flame goes out, the protection system of the gas boiler is triggered and it turns off.

The situation can be corrected only by eliminating the reverse thrust. To do this, it is necessary to identify the cause of its occurrence. For example, adjust the design of the chimney, install a deflector, etc.

Backdraft also occurs when there is poor ventilation in the room. It's easy to check - the flame will burn well when you open the window. The following factors impair ventilation:

• sealed plastic windows;
• hermetically closed doors;
• too powerful hood in the kitchen.

In this case, measures should be taken to improve ventilation.

Chimney problems

A common problem for open and closed gas boilers is frost that forms at the exit from the chimney. Hot combustion products come out of the pipe and are converted into condensate, which freezes at the head. This frost prevents air from entering, the fire is extinguished and the boiler shuts down. The ice needs to be cleaned and the air flow will resume.

If ice builds up regularly, then you need to insulate the chimney.

The classic chimney is more prone to all kinds of blockages. It can get there:

• rubbish;
• pipe elements;
• soot, soot, dry leaves;
• sometimes even birds and the remains of their nests get into the chimney.

Voltage drops in the network

If the voltage in the mains falls below the indication provided for by the operating mode of the unit, the security system will turn off the gas boiler. When the voltage returns to normal, the unit will start up again.

To avoid this problem, you should install an uninterruptible power supply.

Fan malfunction

In turbocharged gas boilers, air intake and combustion products are removed using a fan. If a failure occurs in this unit, the boiler will shut down.

In this case, it is necessary to diagnose the fan, clean it from the blockage, replace the damaged parts, inspect the wiring.

Pump problems

If the pump malfunctions, the coolant does not circulate well through the system. As a result, the radiators do not heat up, and the automation turns off the gas boiler.

If the circulation pump was recently included in the system, and after that the unit began to turn off, then, perhaps, mistakes were made during its installation.

Burner problems

If the gas boiler switches off all the time, then the functioning of the burner should be checked:

1. If the ignition does not occur and the flame goes out immediately, then, most likely, the problem is in the nozzles - they should be cleaned of soot and excess air released. It is also advisable to check the position of the ignition electrode and, if necessary, clean it.
2. If the flame goes out after a short burning, then the diagnosis of the ionization electrode should be carried out.
3. The flame breaks off and the nozzle makes noise - it is necessary to adjust the gas supply. This is sometimes due to excessive traction.

we just put a new boiler on, it quickly picks up the temperature and when it heats it up, it feels like the kettle starts to boil and goes out and at the same time the batteries are cold

Switching on the boiler

1. The gas boiler is plugged into an outlet.
2. The switch should be set to zero.
3. The gas supply turns on (the valve on the gas pipe opens).

Further steps may differ for different models of gas boilers.

For example, the switch for Aton or Danko boilers must be set to the "asterisk" icon, press the entire switch and hold it for 5-10 seconds.

Then, without releasing the switch, press the button located next to it.

The unit will respond with a characteristic click and hum. Then the regulator is released and the required power is set.

To turn on the Baksi boiler, you also need to turn on the gas, plug in the plug and press the "Start" button. Operation sound will appear.The device needs to be given a little time, and it will automatically ignite the flame. After that, you need to press the power button again and thus connect the heating circuit (the corresponding icon will appear on the display). In conclusion, using the buttons, the desired temperature is set.

We will consider the types of generators for gas boilers here.

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.

Malfunctions of Keber gas boilers

Of course, any equipment can malfunction. Keber boilers are no exception. Let's consider the most common problems that the owners of such equipment have to face:

1. Unstable work . Usually this problem is solved by cleaning the jet. In some situations, it is necessary to check the meter, since it may not allow gas to enter the system in the required amount.
2. The gas burner goes out a few minutes after being turned on. There can be many reasons that lead to this, but most often this is due to the failure of the traction sensor. The best thing is to contact a specialist.
3. There is no gas supply to the injectors. If you have purchased a boiler with Arbat automation, then, most likely, the stem is jammed in the middle of the structure. You can drip some machine oil yourself, then check the automatics for gas leaks. If the above steps are unsuccessful, then you should contact a specialist.

When arranging a heating structure, many homeowners prefer the installation of double-circuit gas boilers

When installing modern models, these heating units are reliable, they are economical and allow you to provide hot water supply in the house, but it is important to know how to start a gas boiler correctly for the first time.

Soot contamination of the heat exchanger

During the long-term operation of the boiler, combustion products settle on the surface of a plate, bithermal or fire-tube heat exchanger. Due to the layer of soot, the fire ceases to directly contact the walls of the combustion chamber, the heat transfer from the source decreases, the boiler heats up not so efficiently and does not reach the required temperature regime.

To solve this problem, it is necessary to clean the heat exchanger. Considering that soot settles on the walls together with tar, tar and ash, it is not so easy to clean the combustion chamber after it has completely cooled down. For quick and effective cleaning, you can contact a specialist. Professionals use special equipment to remove soot:

• “Streamer” complex (electric discharge method) is an effective procedure that allows you to remove a sufficiently thick layer of combustion products without damaging the heat exchanger;
• the use of a high-pressure pump (hydrodynamic method) - quick removal of small deposits, the combustion chamber does not even need to be removed;
• booster for chemical flushing. This method is effective if the heat exchanger is heavily contaminated, and soot and tar deposits are old and cannot be removed in any other way. The disadvantage of this option is the risk of reducing the life of the combustion chamber.

All of these methods involve additional costs. For self-removal of combustion products, you can use one of the common methods that are offered by experienced craftsmen. For example, warm up the surface of the chamber with a hot air gun and use a regular spatula to remove the soot.

Characteristics

Today, the products represented by Zhytomyr boilers are the most modern and in demand. To understand why this particular brand has received consumer recognition, it is necessary to consider the model range in more detail.Each individual equipment has a huge advantage over similar devices from other manufacturers.

Considering all the advantages described above, we can safely say that Zhytomyr boilers are ideal for heating private houses, they will cope well with their work in an apartment and in other rooms. It should be noted that not only the beautiful design and ease of use attracts consumers, but also the price issue.

Use of boilers

You can find out the whole truth about the conspiracy associated with the choice, operation and maintenance of heating boilers of all manufacturers and models.

As for gas boilers, there are no subtleties here, you need to set the temperature you need and turn on the device, after a while the heating radiators will begin to warm up the room.

The process of firing boilers on fuel includes the following stages:

• Cleaning of grates. With the help of a spatula, the ash is moved along the grate, and it falls down.
• Cleaning the chamber where ash accumulates.
• Cleaning the walls of the furnace chamber from soot. Wipe the walls with a dry cloth.
• The chimney is cleaned as planned, once a year. If traction is disturbed, clean it as needed.

If firing with coal, you must make sure that a grate for firing with coal is installed in the chamber, change it when switching to another type of fuel.

Ignition stages:

Gas boilers are the most economical, easy-to-install and subsequent type of heat generators used in autonomous heating systems. However, like any engineering equipment, gas boilers can sometimes fail, and the most common type of malfunction is a self-extinguishing burner. To understand why a gas boiler goes out or to find out the cause of other malfunctions, you need to know about the types of boilers and the principles of their operation.
