Got a boiler down for a week now and cant get a service tech for another week. Its been off a week already.Apparently they dont usually take new customers during the busy season. It starts and fires for about 5 seconds then shuts down. Thats the length of the test phase. My best guess is a defective flame sensor, or a weak gas valve not able to open fully. Its a direct vent lo mass with electronic ignition. I have a general knowledge of oil and gas furnaces but this baby has a lot of new safety devices on it and its a bit complicated.
Any ideas.?
