Good day! The gas wall boiler goes out. The ventilation duct is clean. There are no obstacles to the chimney on the roof. A visor was raised above the chimney, but did not give a result. What else can you try? Thanks in advance.

Good afternoon, Eugene. Judging by the above, you have reverse chimney draft. Damage to the boiler is excluded.
I offer three options.
1. Increase the length of the ventilation duct. A simple, yet effective solution.
2. Install the deflector.
The first and second options can be applied comprehensively. I am sure the problem will close. Only if not the third option ...
3. Chimneys check the purity of the channel by looking in the mirror, see a clear sky and conclude that everything is in order. However, your channel integrity may be compromised, and this method will not detect this. Therefore, you must fully view the channel. Check from the inside of the house, go up to the attic, inspect everything carefully.
If you do not find a visual impairment, perform the first and second option. If the problem remains - look for specialists with a video camera, set the problem point.
