If I remember right, I put in cocncrete board they call it, and did my tile on that. it sits on the subflloor, the " floating" hardwood flloor goes up to the trim around the tile. be sure the stove is far enough from the back wall. there I spaced the concete board out couple of inches for air sopace, then did the tile. the wood about the stove will get pretty warm when I have the stoved cranked way up! but has never been a problem. I clean the flue out every fall real good with wire flue brush.
the addition to my car shed in pic besides the stacks of wood along the fence, I plan on just using a double barrel stove to heat that garage area. unless I find a used cast iron stove cheap enough. probably take me all winter to enclose that thing, unless the Pres, sends me a garage "grant", ha
