I had a power vent water heater put in a few years ago. For some reason, the FV sensor decided to keep tripping this year. Not sure why, basement is a bit humid, kids are rummaging down there a bit more often, and perhaps there is some off gassing from old oil spills from the boiler. It's a mystery.
I put the power vent in because plumber said he couldn't get it close enough to wall. But now I see that some direct vent models allow up to 80" to wall, which I can make. And those don't have those FV sensors, right? The issue is that the highest point of cellar wall comes out about 6" above ground. I used a couple 90s to bring the vent up to about 3'. But all the direct vent models I see don't seem to "snorkel" like this? Is allowable, and does any body make vents for this?
