Hi
My oil fired boiler starts and runs for 20 seconds then goes to lock out. When the lockout is reset it will start and run perfectly. I have checked the photocell and it is clean. Would it be a problem with the air pressure being a bit high. Any help appreciated
Get a Service Engineer in who can service and set up the boiler and clear any problems, you don't say what make and model boiler you have, so can't give model specific advice i'm afraid
