After reading a lot about chimney pipe, I came to the conclusion that all are not created equal. Since I got the Duravent kit I figured I was committed to the same brand chimney pipe. Which narrowed it down to Home Depot or Sutherlands. Home Depot was cheaper and I found it in the Duraplus triple wall. Nice thing about this pipe is its the best of both worlds, from what I saw, ceramic wool insulation around the inner pipe, air gap around the outer. Stainless steel inner and stainless steel outer. Bought four 36 inch sections. I hope that's all I'll need, stuffs high dollar.
I'm thinking I'm in the wrong business. I could sell stoves at cost and make a killing on everything else that's needed to install it. Spent $330 for the stove and easily twice that for everything else. But, it's what the boss wanted. So that's what the boss gets.
