Ok well, after much research...i have more questions! The minimum hearth pad size for my stove is 43 deep by 38 wide. And the back of the stove has to be 17 inches from a combustible. (Wall in this case) the max that we can have this stove protrude into the room is 43 inches. If it comes out at 50 inches it is a deal breaker and i will have to scrap the idea of a woodstove. Now my stove has a rear heat shield and we were only going to build a hearth pad, but i spoke to the guys putting in my chimney and he said that if i put durock and tiles on the wall with a 1 inch air gap behind it, i can get closer to the wall than the 17 quoted in the manual because it is not considered a combustible now. Is that true? Cause if it is i can finally have my wood stove I wouldnt go closer than 8 inches, and the black pipe is going to be double walled so that shouldnt be an issue What do you experts say??
