I am installing an Englander 25-PDVC pellet stove in my basement. The basement is mostly below grade, with perhaps what looks like 2 blocks above grade. The house is 25 years old with 2 cell cinder blocks, sill plate, 2x10 joists 16" on center. I don't know if I have rebar run through the blocks. I hope to bring the vent out on the corner of my house, perhaps the first or second joist bay. Ideally I'd like to vent on the rim joist (band joist?) side of the house, but could around the corner (on the end joist side if that’s what you call it?) if it makes life easier.
The problem is the 3" pellet stove pipe needs one inch clearance from combustibles. If I use Dura-vent pipe and their wall thimble (into which the 3" pipe goes) I need to cut a 7 1/2" hole. That sounds like too much to cut out of a rim joist. My other option is boring a 4” hole through the cinder block foundation, but cutting into the last two courses of blocks makes me nervous, not to mention a lot more work than cutting through a joist.
I know this can be done as many folks have pellets stove installs in their basements. I’m pretty handy and would like to do this myself. Can you provide some general guidance on the easiest way to proceed?
Anyone who has done this I am grateful for any help.
