This is my first post, though I've read through the tons of great information on this forum, including many posts about firewalls and shields. Still...I'm confused. I bought an old Fisher stove at an auction last year for $300...then spent MUCH MORE than that on the pipe and installation (see pic). I'm in Georgia so I haven't had a chance to use it other than test firing it late last winter...boy does it CRANK the heat! Right now, I have it sitting on a solid piece of granite above a wood floor, but plan on covering the wood floor with tile, cement board and OSB, as it got VERY hot behind and below the stove. To the left of the stove is a stone wall, so I'm not worried about that. To the right is drywall and that's what I think I should be concerned about...but I'm not sure. The stove is 26" from the drywall and from the stone. In the rear, I've built a half way that is 31" away from the stone, and 20" away from the rear of the 8" pipe. My questions are: 1. Do I need a fire shield at all on the drywall? 2. If so, can I just put tile on cement board and mount that to the wall studs, or do I still need to create an air pocket behind that? 3. Finally, would tile on cement board on OSB work for underneath the stove? Thanks for your help. We want to get off the electric grid, but we don't want to burn the house down!
