I just ordered an Englander pellet insert stove. I plan on installing it myself. In the installation information on their website they show what looks like a flex pipe going from the back of the stove and up the chimney just past the damper. Is this correct or do I have to extend it to the top of the chimney? Also how do you run the air intake to the back of the stove without interfering with the draft? It obviously has to come down the chimney ( I have plenty of room in the 10” flue). Since the insert stove is sealed to the face of the fireplace I believe I should be able to down flow without fumes into room. Is that correct & legal?
I have installed lots of things including wood stoves over the years but never a pellet stove and never in highly regulated Massachusetts. I appreciate any assistance anyone can give me. Thanks for any help I can get.
