just what i was thinking..burner preassure is good but there was alot of dust dirt around the fan to that was maken a noise so cleaned that it sounds no to bad now....thought maybe a restruction in the gas valve but burner preassure is good.
when I read the first post on this thread I though you were the owner of the boiler but it seems you are a "professional". You should register for the "combustion chamber", you will get all the advice you need there.
