Hey yall!
Had an old propane furnace removed and I was left with this massive hole in the tile. I am trying to be as safe as possible, so I thought I’d run it by the forum.
Could I simply use cement backer board running along both walls just high enough to cover the hole then put some corrugated metal over the top of that? If so, would I then measure from the metal to make sure my clearance is sufficient from the stove or from the combustible part of the wall?
I removed a platform because it didn’t fit the requirements for the stove clearance, so the bottom is exposed to insulation and some framing.
Thanks
