We are running an Enviro Milan fireplace insert. It is vented through a flexible stainless pipe connected to 6 inch stainless chimney liner. We have recently had trouble with lazy burn and pellets building up in the burn pot. We have broken down the stove and done a thorough cleaning and cleaned the venting pipe and the lowest part of the chimney liner. We are still having trouble. The vacuum will not go above 10-12 on our magnahelic, 14 is spec for this stove. So, two questions: 1. How often does the chimney liner need to be cleaned when running a pellet stove? ( Ours has not been cleaned from top to bottom for a while) 2. Could the air intake on the back of the stove be affected somehow or what else can affected the air intake if that is clear of blockage? This stove was running great up until last week.
Thanks for any help with this.
