I have a Harmon SF1500 furnace. I want to install a round stainless smooth flex liner of 5.5 inches.
My existing flue = 6 1/8 x 11 1/4 inches (terracotta). The height is 21'.
Furnace has worked fine for 15 years or so with a barometric damper on it and (2) 90's, all 6". Does anyone have input on how it will burn for wood and coal going to a 5.5 inch liner? Hotter or colder? I am located near Harrisburg Pa.
Input I received was 5.5" round should work better than a 6" x 10 3/4 " rectangular liner.
Thanks
