I am working on installing a Fisher Baby Bear wood stove into an old outbuilding approx 10'x11' with no insulation, open studs, no ceiling or wood roof sheeting only metal roof over the rafters. I assume I will need support for the flue at the ceiling height and at the roof exit. The stove exhaust is out the back so I'm thinking a 90 degree elbow to start (or a Tee to save clearance??), going straight up through the ceiling joists, a 45 degree elbow to center the flue between roof rafters and closer to the ridge line, then another 45 degree elbow to go straight up through the metal roof. I will be adding noncombustible material on the studs and a brick hearth for the stove to set on. This is a first time DIY for me. Can someone tell me if this makes sense to work and walk (crawl) me through materials, type of supports needed, flashing and anything else needed.
Thanks in advance for any and all help, Jeff

There are a lot of basics to keep track of in order to make this a safe installation. The stove has 36" clearances in all directions. This can be reduced down to 12" with proper wall shielding but it needs to be done right. It needs to be on 1" non-combustible standoffs and requires at least a 1" gap at the bottom and to be open at the top.


The stove pipe and chimney pipe each have their own clearance specs. Single-walled stove pipe is 18", double-walled stove pipe is 6". Chimney pipe is typically 2". Go to the manufacturer's website to verify.

The hearth needs to be to the stove's manual specifications or in lieu of that, by NFPA 211 spec.

There are many threads on new installs in the Classics forum that have examples. Moving this thread to the Fisher forum for more targeted responses on the Baby Bear install.
