So I have myself a quadrafire Castile pellet stove. This year I am using the same pellets that I used last year, stove chow from Home Depot. However in just a matter of 12 hours or so my fire pot is nearly over flowing with ash. I used to be able to run the stove several days without having to clean it, now it's every day. With the little research I have done tells me that I have an airflow problem. If that is the case how do I even go about fixing this? I cleaned the exhaust pipe as best I can but what else can I do aside from having a technician work on my stove?
