How’s it going, I’m replacing an old wood stove with a 8” class a chimney with a Drolet escape 1800. I will post a picture of the current stove and alcove. What I was wondering is would I get good enough draft if I run 3-4ft of 6” into an adapter above the alcove where it meeting the top of the wall. My chimney runs through the attic out the roof and is probably around 15+ feet. I’m above 6000ft in altitude and this old wood stove works great just eats wood and is cracked and worn pretty bad. The chimney is in good shape and have never had an issue. I’d appreciate any input, thank you.
