In every region of Russia there are settlements where gas boilers are widely used, which is especially true for the winter period. This equipment acts as the main component of an autonomous heating system. In some cases, owners of suburban and private houses within the city are faced with a problem, which is expressed in the fact that the gas boiler blows in the wind. "What to do?" - users will certainly begin to think.
If the device refuses to work properly and constantly goes out, then this is probably accompanied by the fact that air flows in the combustion chamber make the burner flame clogged. If you notice that a warning sign has appeared on the display, do not panic at the same time. In such situations, you need to quickly carry out diagnostics in order to identify the causes that led to the described malfunction, otherwise you may encounter some troubles, namely a decrease in the temperature inside the house or defrosting of the heating system, which afterwards may become unusable.
Ice outgrowth on the instrument head
If the gas boiler blows in the wind, what to do, you must decide immediately. However, initially you need to deal with the causes of this phenomenon, developing ways to fix the problem. According to practice, there are several reasons that can lead to the problem voiced above. Thus, if an ice growth has appeared on the head of a device intended for heating, then it should not be quickly knocked down. Otherwise, you may damage the components of the heating system. If the ice is frozen on the head and inside it, but the oxygen supply is stopped, the gas boiler will certainly die out. Homeowners should gradually defrost the tip. First you need to remove it, and then bring it into the room, only in this way it will be possible to defrost.
While the tip will thaw, the equipment can function without this element. The gas supply to the burner must be shut off before starting. After you can ignite the igniter, the valve must be gradually opened. After the flame ignites in the main burner, the device should be warmed up. Thus, the design should work at a minimum gas pressure. After the progress has been made, the gas pressure you can be strengthened.
If you are faced with such a problem that the gas boiler blows in the wind, what to do, you definitely need to start solving. When the device is operating, it is necessary to monitor the state of the piezo ignition contacts. They should be red-hot. If the contacts cool, the gas pressure must be reduced so that the thermocouple does not cool. Otherwise, a signal will be given, which will contribute to the operation of the automation.
The reason is insufficient gas pressure
Often, users wonder why a gas boiler blows out in the wind. This problem occurs when the pressure of the gas entering the equipment is low. A malfunction of the gas transmission network can be expressed in the breakdown of the gas meter. After this element of the system fails, it will pass the necessary flow of fuel. In order to make sure that this is the problem, you should check the status of the counting mechanism. The first thing that will indicate a breakdown is uncharacteristic sounds made by the counter. If you have a question about why a gas boiler blows out in the wind, be aware that this can happen if the temperature sensors or leakage are broken. Representatives of the gas service are guided by the established rules; they require the installation of gas analyzers. If they work, the gas boiler will go out.
The cause of attenuation is a leak in the joints
In order not to blow the gas boiler with the wind, the complete tightness of all connections is necessary. If they are broken, there will be a gas leak, which will cause a pressure drop. After the signal is given, the automation system will work, then the unit will turn off. When such a problem arises, home owners will smell the characteristic gas. In order to eliminate a similar cause of attenuation, it is necessary to check the connections using a damp sponge soaked in soapy foam. Bubbles will indicate a leak. In this case, urgently need to call the gas service workers.
Chimney problems
If you notice that in a strong wind a gas boiler blows out, then the problem may be caused by a malfunction of the chimney. This reason is one of the most frequent. A malfunction may occur due to the formation of ice. It is observed when the steam entering the chimney with the products of combustion is cooled, and then it settles in the form of condensate on the base of the walls. The condensate gradually freezes, forming a fairly thick layer of ice. After this, the draft decreases, the automation turns on, and the boiler, accordingly, goes out.
If the parapet gas boiler blows with the wind precisely for this reason, the chimney assumes the need for cleaning and warming, this will prevent condensate from flowing down, which will not lead to freezing next time.
The reason is reverse thrust
This problem occurs if the wind outside increases or changes direction. Air enters the chimney and blows out flames in the boiler. In some cases, this is due to the low height of the pipe. This phenomenon is quite dangerous if the boiler is operated with poor automation. It should be feared that the combustion products will enter the house, pumped by the wind, instead of being thrown out into the street. If the problem arose due to the small size of the pipe, then the master should increase it. Its height should be more than 50 centimeters in relation to the ridge of the roof.
Insufficient ventilation
If you encounter a problem, which is expressed in the fact that the floor gas boiler blows in the wind, what to do, you should decide only after determining the cause. It can be expressed in insufficiently intensive ventilation. In some cases, it may be sufficient to open a window or door so that the burner lights up and the equipment starts to work. To improve the air circulation in the boiler rooms, the hole located at the bottom of the door must be closed with a fine mesh.
The reason is the burnt pipe
If a parapet gas boiler blows in the wind, what to do, sometimes only a specialist can say. Burning the pipe, by the way, can also lead to attenuation of the device. This is due to the fact that a burnt hole blows in the wind, thereby impairing the functioning of the chimney. If you encounter such a problem, you will need to replace the chimney pipe.
Failed automation
Turbocharged boilers have fans that are designed to provide traction. In the event of a breakdown, the wind starts to buzz excessively, if the fan fails, it must be replaced. Atmospheric boilers operate with a draft sensor. It starts to work when the temperature in the smoke trap increases, at the moment when steam that has escaped from the pipe penetrates into it. If this sensor is defective, then a signal occurs, the burner, in turn, goes out.
Lack of electricity
If you thought about the question of why a gas boiler blows up in a strong wind, this can occur when the voltage drops in the electric network. This happens even with quality equipment. This phenomenon is due to improper operation of automation. Such shutdowns can adversely affect the electronics of the device, which can fail. If the gas does not ignite when the electricity is connected, this will indicate that a breakdown in the automation has occurred. In order to eliminate such problems, you need to purchase and install a voltage stabilizer.
If after eliminating the above reasons the boiler does not start working properly, the problem can be expressed in the malfunction of the unit.
Conclusion
If the gas boiler blows in the wind, what to do, you can decide for yourself. However, malfunctions can be expressed in the fact that the main burner does not turn on or burns weakly. A possible reason is the clogging of nozzles, which can be cleaned with a wire of small diameter.
If air has been injected into the gas system, an error code will appear on the device’s display. The equipment must be turned off and restarted. You can familiarize yourself with the methodology for carrying out these manipulations by reading the instruction manual.
If the burner does not light up at all during automatic or manual ignition, this may be caused by a violation of the gap in the electrode. You can try to adjust it yourself, but to do this is quite difficult.
