Hi All, sorry to make a zombie thread.
I have been lurking for a few months as I researched my new, to me, Biasi 3-wood boiler.
The person whom owned it before we moved in only burned wood in it and it looked like it produced creosote like crazy ( which seems to be the trend with these when burning wood). I will be burning nut anthracite, after I get the chimney swept.
Anyways, here is my question, earlier in this post someone mentioned putting in a barometric damper and asked if it was ok to put a 6" one? No one seemed to answer him. Seeing how the Biasi has a 7" output I was wondering if it is ok to reduce the pipe down to 6" and then I can put in a Tee with a barometric damper. The 7" is really hard to find, and It seems like the 6" dampers are easily found and cheap. I suppose I could increase to 8" If I need to.
Thanks for any help you can give! This is my first winter burning coal. I recently moved to Downeast Maine. I am sure I will be back with more questions as I start burning this winter.
