Pretty much pellet related. We seem to get dusty pellets here and accumulate a lot of fines and pieces of pellets in the fines box. Recently I cleaned it. Within a month I needed to pull the ESP for cleaning and while there opened up the box again. It was nearly full. Right now the pellets I have are not particularly dusty though but I also have not cleaned the hopper in some time, nor run it low enough to get to the dust in the hopper for that matter. So it either runs through and burns up or lands in the fines box. Other times I've opened it up and it was nearly empty after a month of burning. I can almost always count on a few pellets being in there though but this last time was almost all very fine dust.
