Question on Clearance

[southbalto]

I'm considering reconfiguring our hearth and need clarification on what’s considered non-combustible. My stove would top vent and then rise 3’ or so before turning 90 degrees and through the wall into the Class A tee section. My house is all wood framed construction; no masonry.
If I were to use metal studs, hardibacker/durarock, and unfaced insulation for the 4’ wide by 8’ tall wall section behind the stove, would that wall then be considered non-combustible? I’d really like to keep the stove as close to the wall as possible.
Thanks

Technically this sounds correct. But be sure to document what you want to do and get it pre-approved before inspection. I would take photos too when in the framing and insulation phase and use Roxul in that wall. Note that this only relocates the rear clearance as measured to the outside sheething of the house if that is the nearest combustible.
