Greetings! I am new to this so please bear with me. I have a summers heat 49-shcpm multi-fuel stove that seems to have a problem. Started burning for the first time in October. Everything was going great...burning ultra premium less than 1/2 percent ash wood pellets. Then yesterday I woke up and the stove was hardly burning at all. Heat range was at 7 blower at 8 and there was little more than a smolder in the burnpot. Even at 9 and 9 there is not much difference. I had everything tore apart cleaning what I could get to and doing the diagnostic test and everything checked out fine. I was running the flue pipe straight through the wall and dumping right out....thought that might be the problem so I added three ft. vertical to it with a 90 at the top, but I think it runs worse. I don't know if maybe there is ash down inside the exhaust system somewhere I can't get to? I did take the blower off and the clean-out plate on the left side and I could reach my hands in from the front and the back of the stove so that my fingers could touch and I could feel no blockages. Thank you for any help or suggestions.
 
Do you run it w/ a Thermostat? If not...

Sound to me like your Thermostat jumper wire is off or loose.
 
Check your jumper wire @ T'stst connection on control board.
 
Whitetree, I have the same stove. Did you make sure that the ash pan is closed tight, and the door is not leaking? Also, are there pellets being fed and just not burning, or is it that very few pellets are feeding?
 
To the best of my knowledge both the door and ashtray are closed and tight. I tried experimenting with that also...opening ashtray then closing it and so forth. I even opened the door and fed about a handfuls worth of pellets to the embers and that works great until they die down too. I also timed the auger to see how long it took to make a revolution. 3 min on level 1 and about 1:30 on level 9. The pellets are feeding, but as they drop in the burnpot I only get a very small flame then they just glow red. I was also getting a lot of clinkers. I read where someone else changed the low fuel feed and low burn air settings. I am going to try setting the LFF to 3 and the LBA to 5 and see what happens.
 
It sounds like a lack of burn air if the pellets just burn low. Sounds like classic dirty stove to me. How many bags of pellets have been through the stove since the last MAJOR cleaning?

By major I mean everything...both blowers removed & cleaned, firepot/firebox and ash traps behind the 2 doors on each side of the burnpot, the entire pipe from end to end, etc.

Did you install the OAK?

I run my 10-cpm on lower button settings of 1-1-1, and occasionally on 1-2-1 if I'm using lower quality pellets.....here's a pic of my stove burning after last cleaning last weekend:

Whitetree,


To explain farther, if jumper is removed, stove will remain in a Setting #1 or #2 as it is waiting for a T'stat to close wires for the signal to ramp-up heat.

Jumper is required to be in place when no T'stat is desired to allow stove to get at higher setting than a #1 or #2.
