    power vent?

    I can only assume that there is a power vent on the oil fired warm air, sounds like a Side Shot? If the thermal switch tripped, you had excessive heat somehow. Either the vent is not wired properly and the draft fan did not run last cycle, or the post purge is not post purging due not being wired properly, or post purge time relay is no good. Need more info. The gas unit I couldn't tell you what is wrong.

    Three Beeps:

    Bill,

    I once shut off a boiler to work on it on a Friday and left it off for the weekend. It was cold but not to freeze up the house. I finished up on Monday. I fired off the boiler, a Weil-McLain HE-6, and it wouldn't fire. No draft or fan prover switch open.

    Over the weekend, the little meeces got up inside the boiler where it was warm and toasty and gnawed on the red and white rubber tubes for the draft prover switch. That took me a few to find that one.

    Today, it is a Munchkin. Lets see them meeces get inside there.
