However you also mentioned going through the ceiling and your concern is the ceiling joist. Most manufacturers of stove pipe have some type of thimble for the pipe to pass through, and usually recommend at least double wall insulated pipe to be inserted through the thimble and allow the double wall pipe to be as close as 2". The kits I've seen have the black pipe terminating at the ceiling box, adapt a collar from it to the insulated pipe, and then run that through the ceiling joists. (If this makes any sense to you.)
Perfect sense, I have the through the ceiling kit (thimble, adaptor from single to double wall, trim ring etc.) just wondering if my single wall pipe from the stove to the ceiling box will be ok 6" from the new non combustible wall ?
