I'm glad I did it. The ceramic tile behind the stove gets too hot to touch. Before I installed the stove, I put a torch on the tile while I could still get to the back side, also stuffed fiberglass insulation between the metal studs. The tile was almost red hot. The back side of the 1/2" concrete board was still cool to the touch. House fires are bad.
I am really glad my husband lurks here to see this.
I hope he's not a liberal. He'll do the opposite just to show that he can.
No, thank the Lord, He gave me a conservative! I even have a conservative MIL!
