Hello all, I have a Buck 91 that I will be installing (my first stove) and have a question, actually I have many questions. I am going to do a direct connect with block off plate for now and do a full liner when $ is available. My question is, If I reduce from the 8" flue to 6" pipe will this radically affect draft, or perhaps improve it? I mean since its a direct connect and till only have a short length of pipe to create a draft wouldn't the reduction actually improve this? It seems to me that it would, I'm sure that there is some equation that factors in diameter x length to equal a particular draft %, but I am new to this so I leave the question to you all. Thanks.
