Ferroli Boiler help please

[philip001]

Hi,
I got a ferroli combi boiler from about 1992.
It hasn't been used a lot since this was a holiday flat so it's not really old.
Everything works well except for the fact that when it lights up for heating as it's warming up, i can see at times the gas seems to stop and then few seconds later it relights and on and on like that. I have done a service on it so i wonder if its because i thighted the cassing screws to tight ? and they might be some air coming in from the fan section that makes it turn off the gas ? Or what else could it be or is it just normal ? Thank you very much.

Phil.

Are you an RGI, Phil?

You should only be working on a gas appliance if its your own property AND you are competent with gas.

From what you have said above you seem to be potentially dangerous.

Do the right thing and get a competent CORGi to fix the problem SAFELY !

i had a similar problem which was cured by changing the venturi in the fan but other symptoms will cause this

Ferroli combis of that era have positive pressure cases and are therefore potentially very dangerous. We should be careful not to give any encouragement to non-RGIs to meddle with them (adrian k please note).
