I have been on woodstock's website, looking at all the clearances specs, I noticed that the stove vents out of back instead of the top. my question is if a man uses 1/2 inch cement board on the floor and on the back of wall with tile installed on it with a gap space between the wall and cement board how close can you install this stove and be safe also use double wall pipe to? I wanting to install it in the corner, but i could install it in the center just wondering, I don't want to take chances with my family with a careless install
