Ive been installing my supervent stove pipe today and got it from my stove to the ceiling but I have an extra part. It came with the universal chimney pipe adapter. It has two holes on it and looks like it wraps around it somewhere. Kinda stumped, don't wanna be tearing it apart in the winter. http://www.menards.com/main/heating-cooling/venting/black-double-wall/6-universal-chimney-adapter/p-1323231-c-6890.htm This is what it came with it, can really figure it out. Anybody else use this?
