Boulter classic 95/130 oil boiler

[jogger62]

Hi everybody I am new to the forum and hope you can help.
I am pretty good mechanically.
I have a problem with my boiler .
on firing up just a few seconds after the burner has ignited there is a single load clunk.
It is not the pipes, but it sounds like it comes from the boiler.
The boiler operates normally with no other problems.
Can you help me please.
Thank you

Needs the combustion testing and probably a good service.

Time to get on the phone to your oil engineer.
