Harman P43

[bmeyer]

I bought a Harman P43 used last year from a friend and after dealing with it running dirty nearly all of last year. I changed my 3" exhaust pipe from being approx. 25' w/cold air intake. To approx. 6' feet with cold air intake going out the side of the house.

I see it is already running cleaner, but one main problem I was having before and still having is the stove when it goes to shut down it burns the pellets all the way back up into the auger. I end up with smoke in my hopper an scorched fines in the auger feed.

I changed the Control Board expecting that might be causing the problem, but we are still having the same issue.

Any thoughts?

Ihave a HarmanP61A and when shut down, the pellets burn pretty much up to the auger..
I just assumed this is normal. No Smoke in the hopper though.
