A friend of mine is looking for a used stove to put in her double wide. Since we bought new for a stick built I never paid attention to what stoves were approved for this install. Are the clearances for manufactured listed on the tags, and if there aren't any listed, is it a safe bet that the stove is not approved for that type of install? I know a number of newer stoves are, but one possible stove she's looking at is an older BK (solid door type, pre glass door). Just want to be sure she's looking at the right stoves!
