When I built my house, I planned to put a Quadrafire 7100 in but now I have a really hard time justifying the $6000 cost (including installation). I am now considering making the wood framed "fireplace" look like a masonary fireplace opening and installing an alcove approved woodstove instead. I will line the "fireplace" opening with the required layers of non combustible materials and can easily maintain the required top, side and back clearances if I pull the woodstove out and onto the hearth, leaving only a portion of it actually inside the "fireplace" opening. The front clearance is what is throwing me off. The woodstove I am considering (hearthstone Heritage) calls for 16" in front of the stove. The total hearth depth from the "fireplace" opening to the front of the hearth is only 20", but the hearth raised 15" off of the floor. If I pulled the woodstove forward to get more of it out of the alcove and into the room, it will only be 8" away from the edge of the hearth....but also 15" up off of the floor. How are the stated required clearances affected by this raised hearth? Technically, if you go straight out from the stove 16", there are no combustables.....only air with a wood floor 15" below that. Thanks!
