Why does the boiler smoke? If you encounter a similar problem, you cannot continue the operation. Smoke and soot indoors are unacceptable. First of all, it is dangerous to health. The equipment will quickly fail if you continue to operate in such conditions. Therefore, it is necessary to establish the cause of the appearance of smoke, and then proceed to eliminate it.
What to do if blows a gas boiler
The first and main reason that the boiler smokes is poor draft in the chimney. This problem is typical for devices with an open combustion chamber, which require connection to a common chimney shaft. To maintain the flame, the technician takes oxygen from the room, so high-quality ventilation is organized.
The draft in the chimney allows the removal of combustion products during the operation of the boiler. At the same time, it supplies oxygen to the ignition unit. If there is no draft, the burner may go out, carbon monoxide will begin to flow into the room.
Why are there problems with traction and smoke does not go into the chimney? There are several reasons:
- Chimney clogging. A mine can clog with extraneous debris and foliage from the street when blowing in the wind. On its walls, soot accumulates over time, which narrows the passage of the chimney. Another problem: blocking the top of the pipe. This happens when the hole is blocked by a satellite dish, a lid. In winter, the hole is clogged with snow.
Combustion products are vented at high temperature, so condensate settles in the mine. In the cold season, it freezes, forming ice.
- The installed chimney type does not fit your model. The pipe diameter is too small to effectively remove the burn. Perhaps the installation was not carried out correctly, slopes and heights in accordance with the standards were not taken into account. If the structure is too low, a pressure mismatch will result. Therefore, natural traction is not formed. A rarer problem is the installation location. For example, placement on the windward side. Or nearby stands a tall building that blocks the flow of air.
- Leaks. Make sure the pipe joints are tightly sealed.
If the Buderus, Baksi, Vailant floor boiler is located in the boiler room, ventilation for the air supply must be on the same side as the chimney. Otherwise, in windy weather, smoke will enter the room.
- Reverse thrust. This is caused by weather conditions, for example, blowing a mine by the wind. Differential pressures also lead to problems.
Trouble-shooting
The presence or absence of traction is checked immediately. Light a match and bring it to the boiler control window. If the flame deviates to the side - there is a draft, it burns exactly - no.
To understand the cause of the problem, look into the tap hole with a mirror and a flashlight. So you can check for clogging, snow accumulation. For your part, you can clean the shaft. And for cleaning from the street it is better to contact a specialist.
See which chimney fits your model. Install the product with the correct diameter. Then carbon monoxide will be qualitatively discharged. The length of the pipe must comply with the regulations, and be higher than the ridge of the roof.
To prevent ice from freezing inside, warm the mine. For self-design, use the sandwich design. She already comes with a heater.
Inspect all joints for cracks, damage, inconsistencies. Press the joints more tightly, use a special sealant to isolate the cracks. In boiler rooms, open the window, creating natural ventilation.
Follow our recommendations, and uninterrupted operation of gas equipment is ensured for you. Regular breakdown prevention is the key to effective heating of your home.
