Hello folks, I'm going to be installing a Drolet Savannah wood stove in a corner and I'd like to do so with minimal clearances. I'm finding it a little confusing to determine precisely what those clearance are. Naturally I'll be using double-wall stove pipe and a heat resistant wall covering - 1" air gap using steel strapping and cement board covered with tile and the appropriate air gaps at the bottom and top (though if I can find some suitable decorative metal I may use that instead of the tile). The confusing part is that the instructions state a 12" minimum gap (for double-wall pipe) between the rear corner of the stove and combustible materials. That distance stays exactly the same for the U.S. once you add a wall shield because 12" is the minimum in the US. But I'm in Canada and the manual says the distance can be reduced to 50% with the proper wall shielding (or 67% with sheet metal) and there's no minimum stated for Canada. Does this mean I can install the stove at 6" (or even 4") from the corners to my drywall? That would be great except I like to understand why the difference. Are US regulations too strict? Has no applicable testing been done with wall heat shields? To me this makes about as much sense as how double-wall stove pipe above the stove significantly affects how close the stove itself can be placed to combustibles. Thanks for your advice.
