Firing the stove this morning I noticed the stove was burning much hotter then is ever has. Standing 2ft away, it was very hot. Never have I felt it this hot from that distance. Maintenance on my Accentra stove this year included : Air bypass tube, new door gasket, hopper gasket, cleaning the chimney liner and blew out every nook and cranny with compressed air. I was wondering if the bypass tube alone could cause these favorable results. Also I replaced the door gasket twice because I questioned the quality of the rope gasket that came in a 3/8 kit that I purchased. After installing a 3/8 gasket that came in the kit I found some sold in bulk that was more dense, rounder and didn't collapse as easy. Is there a specific gasket that Harmon recommends? Overall Im very pleased with the end results.
