Thanks for the helpful comments. Yes, I was under the impression that I might get a season before pulling the insert out and cleaning the exhaust flu, but don't think that is going to happen. My house is over 4000 sq ft, stove sits in a great room with very tall ceilings, so most of the heat is going upstairs. As a result, the stove never throttels down, so when it gets cold, I can us 3 bags a day easy. I think those that have once a season flu cleanings are blessed with a smaller and more contained area. Was hoping someone would wiegh in on experience with Turman hardwood pellets. I purchased 4 tons when I got the stove, so have not had the need to buy a different brand yet this year. Was told they burn pretty clean. Tractor Supply here in town is getting a shipment in tomorrow, may try some of those.
You can only go upon your experience. That pic doesn't look too bad, but the evidence is that you got an error code and the stove is running alot hotter than before. So, I'd say you need to clean more often than once every 3 tons. Or maybe adapt your cleaning routine. Can you do the LBT every month, instead, perhaps that will allow you to run a whole seasons without having to pull the insert.
