Hi All, I hope you haven't heard this same old problem before, but I need help! (Sorry for the long post!) I have an Avalon 900 series Pellet Stove and I have been having some big problems with it. Basically, every day for the last 3 or 4 weeks my stove has been clogging. By clogging, I mean enough clinkers build up in the ash pan that the pellets start blocking up into the feed tube. When I go to clean it out, there is a big hunk of clinkers in the stove. Here's the weird part. Same thing was happening towards the end of last winter. This year, I burned for a month or so going every week between cleanings. Gradually, it got worse and worse to where I am now at cleaning every day. Let me go through my list of things I have tried to fix the problem: Clean the stove (I think I know every place to clean) Clean the chimney - (did this, got a couple days of good burning, then clog) Clean the exhaust blower - (did this when I cleaned the chimney) Change the door gaskets - (just did this, no help) I am at a loss here. My local pellet stove dealer is no help at all. I have been talking to them on and off about the problem and they don't seem to worried about it. I am hoping someone here might have some thoughts on what else to try. My next step is to check the vent screen up on the roof. Fortunately most of the snow has melted so I might be able to get up there this week sometime. That is pretty much all I know left to do. Can anyone help??????? EDIT: I have always burned Dry Creek Brand pellets and another brand I have tried have clogged worse.
