I am having a new shop built in my backyard and I'd like to heat it with a new wood stove. It is a 16' x 24' barn-type building that is 16' high at the peak. Therefore, since the stove will be situated in one corner of the building, I believe the distance from the top of the stove to the exit point through the roof will be approximately 12 to 14 feet. From what I've found through my searching, it sounds like this will most closely resemble an install for a cathedral ceiling. Is it possible (and legal) to have a stove pipe that long? And if the answer is yes, does it need to be a special kind of stove pipe for that length of run? I'm a newby and this will be my first woodstove, so any info on this subject would be greatly appreciated.
