I ran out of home-heating oil and there now appears to be an air lock in my oil burner. I've looked everywhere but I can't see where the bleeder valve is.
I have attached 2 photos, one of the burner, and the other of the front cover of the burner.
What happens is this: i press the re-start buttom and the boiler appears to fire up. It runs for a bout 10 seconds and then stops.
Any help would be greatly appreciated.
