I have a Glow worm Fuel Saver 55F. The burner lights up for about 60 seconds and then goes out eventhough it is still being called for. I think the fan is going off before the burner. has any one got any ideas.
Yes the pump is running, is doesnot seem to be overheating as the burner is only on for less than 60 seconds and the pipes from the boiler are hardly warm
