Learned slot about chimneys last night after finding that nothing I bought fits my stack.
Apparently my shit should have burned itself down years ago: I just have stovepipe through the attic and up. Way way way under any current code, and no currently purchaseable flashing.
So I need to get some engineered chimney and make my holes a bit bigger and everything safer.
Must go taller too. Minimum 3’ now (and 2’ above anything in a 10’ radius), I might have been 30†to the top of the rain cap - but I doubt it.
So yet another shooing trip. I’ll lay courses now until it gets hot, then go shop.
