ReplyI had a crown boiler with a bad spill switch right out of the box, is it spill or rollout? I don't remember if I read which one it was.

Lol... Terminology...,
Code up here stipulates 6" above expected snow level so we go 24" minimum off the roof. It sounds like a high wind cap is a good idea.
Do you have adequate combustion air supply in the room? Should be 5" is your inducer fan working properly? Those inducer fans on the carrier mids like the pav/wav and tua tend to get tight bearings over time.... Check your draft at the pressure switch when the furnace is running.
Given that your vent is so short, is it possible the vent is undersized?
