Finally got around to adding another section of pipe to my chimney and the improved draft is actually noticeable! My total chimney height from stove top to cap was barely 12' and just didn't seem to have good pull out of the firebox. After adding the 3' section of Duraplus triple wall SS pipe the stove is def breathing better. I've been burning the same wood for about 4 weeks now and it seems to be burning easier with the added section of pipe. I know I need to give it a week to truly know but I'm liking the results so far!!
