Isar loud noise, going to f l fault but ok with....

Check it via the pump?

It's an issue with rectification leads. Buy kit

Start the fga with cover off then fit the cover. You would have seen the O2 dropping rapidly and the CO rising before the fl lock out.
It would have told you straight away what the fault was.
Im not having a go just pointing out you can get a lot of information from the fga not just ratios that will tell you what the problem is.
I know hindsight is a wonderful thing and I am just passing on information that maybe of use to people.

Ahhh didn't know it was staying lit once it got going!!!

note I said airflow mate.....I know about the test point for fg. The last one that I had where the flue seals had gone it had tell tale signs of condensation re-circulating back to the boiler as the combustion chamber was full of condensation...guess I was looking for that

Like I said mate, if you start with case off then case on it will show an air flow fault. Also like I said earlier run with case off and put your fga up the outer flue at the turret. Any CO reading will tell you the internal seals have gone. Still a lot quicker than stripping the flue down.
