    Have a Jotul 606 and 380 but the manuals only show install clearances to combustibles. Anyone know the clearances to non combustibles?

    Like a concrete wall or brick? I don't there is a min distance but someone will have to back me up on that. Maybe putting a 700 degree chunk of steel an inch away from a freezing concrete wall isn't a good thing, just seems better to have a little room.

    So you are not talking about a non combustible wall? It is a combustible wall with noncombustibles on it?

    Its a non-combustable wall protection. I thought combustables were defined as furniture, plaster, etc.

    Just covering a stud wall with a non-combustible product does not make the wall non-combustible. The granite will conduct heat to the drywall and studs behind it. If there is a pure concrete wall behind the granite, then that is truly non-combustible. Otherwise. the closest you can bring the stove to a combustible wall is 12" and then only with a proper NFPA 211 wall shield.

    Thanks for posting that link. Based on that Chart and the clearances to combustable with my stove(32") and the granite spaced from the wall at 1" allows for a 66% reduction. Thats about 11-12."

    It is 12" that is the minum allowed unless specified by the manufacturer. And that is only if that granite is spaced off the wall 1" with noncombustible spacers and has atleast a 1" gap top and bottom to allow for airflow. And that 12" is to the combustibles not the granite.

    That makes sense. Accept for the Air Gap at the bottom. How can you have an air gap at the bottom of the panel? from what I've seen the wall panels sit flat to the floor protection.

    If you saw that it was wrong and provided no clearance reduction. You need air to be able to come in the bottom and flow freely up behind the panel and out the top.
