A lot of folks around here are converting from oil to wood pellet furnaces. I have heard a few people say that they discovered that certain pellets will stall out their auger as they will jam in the tiny space where the auger meets the edge inside the pellet box. This limits them when the pellets get scarce (which seems to happen in waves)
Seems more like an auger design issue to me. Those who don't complain seem to have a much tighter fit at this spot. Perhaps something worth eyeballing when you go to look at a stove.
