Boiler is 11 years old and very efficient, but have experienced intermittent ignition problems for a couple of years now. This has foxed more than 10 different heating engineers, but it has to be a simple solution imo.
Current symptoms
When boiler comes on it sparks for about 30 secs, and then the pilot comes on, but the flame looks small, and looking through the window it appears that it is being blown around. It also looks like there is another flame just above it. The pilot flame doesn't seem to be reaching the burner. If I tap the boiler it ignites. I can also ignite the boiler by restricting some of the air out by putting my hand over part of the flue on the outside wall
Sounds to me like there is too much air around the pilot. Is it posible that I have a faulty door seal?
I have had several engineers look at the boiler but no one has been able to fix it, but every time they take it apart and put it together it works OK for a while. Had a new fan gasket a few months back, and also new pilot assembly and gas valve a while ago.
When the boiler is warm or hot, and then comes back on, one spark, the pilot lights and it ignites immediately.
Any advice would be appreciated.
