Hi Agile (Tony) unfortunately I agree with Bernardgreen, it's a complete lottery whether you get a truly skilled gas engineer or a dodgy one, i've had a few dodgy ones in the past who just want to do a quick clean and vacuum and charge for a service they haven't performed. They may be gas safe...
Hi steve32, thanks for your reply, step flow gas release is where the gas valve releases a lower pressure at ignition to get the flames alight and then a few seconds later opens to release the full burner pressure. It's a means of reducing that initial whoosh of noise and combustion that some...
Thanks Agile, however finding an engineer from a telephone book, who will understand how the step flow works will be nigh impossible.
As it seems here, this is not something that is widely known.
Gas engineers seem to replace items based on a best guess which seems a costly and not best...
Hi petit_pablo, thanks for your reply, can you please explain what you mean by "The main burner is backlighting at the injector" ?
The burner was removed and cleaned has something been missed? why would this affect the step flow gas release?

Hi AGAS, thanks for your reply, it's not a matter of the cost, if the step flow is not controlled by the gas valve why change it? The reason why the oxy pilot and electrode were changed was due to intermittent sparking issues, that didn't help and eventually the sparking failed altogether and...
Hi can someone help resolve issue with burner fire up on my Potterton Housewarmer 55?
The burner seems to start mostly on full gas, the lower flow at startup seems to be failing most of the time.
This means that the boiler igniting is quite noisy, on the odd occasion that the step flow seems...
