I just purchased the Englander 50/13 series stove for my cabin in upstate NY. The building is a 24x20 with a loft of the same size. My ceiling on the first floor is also the floor for the second story loft made of knotty pine. My question is should I run the pipe straight up through the first story ceiling/floor then through the loft and then finally through the roof? Alternatively, I could run my pipe straight out and run the chimney entirely along the outside of the camp. Cost is also an issue. Thanks
