Ok mate cheers, I’ve never had to do this before . Is it just a case of adjusting it while it’s running with the analyser in and watch the reading drop as I go ?
I wouldn't start altering it until you've checked the burner seals etc. Could be something simple like that. Have you checked your 02 readings on air intake too?
Wow! JT, I asssume that you are registered? How can you nit have adjusted a gas valve before now, is it not part of training these days. Not trying to be a Smart A, I am genuinely confused - it is a basic function.
Choppers: Before you start worrying about seals, it is normal to reset the gas valve, as they drift. I had to adjust a Worcester yeterday. The CO2 was 9.1% on high. I adjusted but Overstepped, and the CO shot through the roof!. Slight readjust and bang on 9.8, and CO, IIRC, about 95.
If you cannot adjust to correct parameters, then start looking at other stuff.
Or am I missing something?
