We bought a used pacific energy woodstove and it came with the pipe. Unfortunately we need a few more pieces of pipe but we can’t figure out what type of pipe we have! I don’t know if this matters but we’re in Canada. There are no stickers or anything to identify on the pipes. The woodstove was a 2008 pacific energy alderlea t5 classic so I would assume the stove pipe/chimney is from the same year. Also, one piece of the black pipe has a dent, will this need to be replaced?
