There have been several posts on hopper fires recently. As I am not home a good portion of the day, that makes me think (and thinking tends to hurt my head). I realize that it is not a common occurance, but it can happen. Just like most things in life.

From reading some causes, it appears that one cause is a failed auger motor allowing the flame to follow the auger up into the hopper. Also, bottom feed units can be more prone to this too, correct?

When I was looking at many different stoves the year before buying, I noticed that most hopper bottoms are open directly to the auger.

On my P68, here is a metal plate that slides and (I think.....ouch that hurt again) allows the pellets to drop into the auger tube.

My question is this....will that plate lessen the possibility of a fire getting to the hopper by acting as a barrier?
 
gbreda,

I don't have a bottom feeder or a Harman. But I can clear up some things.

On the bottom feeders auger motor failing may cause the hopper fire. On a top feeder if the auger fail's the fire will just go out. The hopper fire on a top feeder comes from pellet backups from the burnpot into the auger chute. As far as I know both stove may have hopper fires. Just takes different things for it to happen.

I wish I could answer all of you q's. But I really don't know. Someone will chime in and reply.
