I’m going to install my Hearthsone Mansfield in my log home . I’m looking for recommendations on what is the best quality pipe to use . Dura vent , Duravent plus , Selkirk double wall, Selkirk Super pro or Shasta vent . Or any other brands that come to mind. The install will be straight up about 7’ through a 12/12 pitched roof of 9” polyisocyurnate insulation board and metal roof. Then up approximately ? ft. and capped. The pipe will exit the roof on the left corner of the house about 12 ft left of the peak and 8ft from the dormer . Total height is yet to be determined but will likely be 2 ft above the dormer .
