Posted this in the hand fired forum, but then figured it may be better over here. Sorry for the double post
Getting ready to light the coal furnace this weekend and would like to replace the flue pipe. Not sure on the age/condition of the pipe, but wanted to take it apart and clean anyway. Figured I'd replace while I'm at it .
Anyway, local store sold me galvanized pipe (8"; 26 gauge or so I believe). The elbows purchased were mistakenly 9", and the only others I can find on the weekend are 30 gauge from Lowe's. Everyone is sold out of the black elbows in 8" ...
So, is this stuff too thin to use with coal? As far as the galvanizing goes, I've read different stories on the pipe and zinc fumes, but the concensus seemed to be that it will only occur if really hot (and only burn off once). Thoughts?
