Hallstead Finest Platinium Boiler ( LPG)

[OMD1]

Hello
Gas Engineers

I have a problem with the boiler on DHW draw off, burner not lighting ignition gas pressure 8mb and spark ignition firing. Boiler does not light , can the ignition pressure be adjusted on this gas valve. I dont see any pot adjustments on the PCB. If i loosen the screws on the front cover it will fire up (most of the time). Can anybody HELP !!! P.S What should the resistance be on the fan motor windings. I would appreicate a bit of help.

You won't get any gas related advice on this open forum. Register for the Combustion Chamber and all your questions will be answered.
Loosening the cover to get it to work indicates to me that you are out of your comfort zone.
