I started up my Astoria late sunday night and have had it on and off since. In that time period I have had 4 jams. All at the top of the chute. I get these occasionally maybe once or twice a season.. ten times when I burned freedom fuel pellets (impossibly long pellets). But the pellets in the hopper are dry creek and are average size... the only difference is they have been in the hopper since last winter.. is there a connection?
