Stove was cleaned good, even blew exhaust with leaf blower. Its on for second time since cleaning. Getting a soot build up which I haven't before any input would be appreciated. [Hearth.com] Lopi Foxfire soot
 
Low cold fires cause black soot
AKA cold smoke
 
What pellets are you using? What level are you burning at? Is the combustion blower working as it should?
 
Golen fire pellets. Feed rate at 1/4 and air flow set to pellets jumping in burn box but not out of it. Combustion fan was replaced last season. I didn't have this soot last season.

Did the air control knob on the left side of the stove get moved when you were cleaning?
 
Are you referring to the knob that controls the air flow through the burn box?

Yes, if it was moved, it could create the soot. Many folks take nail polish, lacquer paint, etc to mark proper positioning for their normal burn settings. Sometimes even a minor adjustment can make a difference. A low burn in not your most efficient burn ... Air flow needs on the damper may change with different heat ranges or different pellets.

Any other changes to your system or to the house that would effect airflow. Some folks have found disruptions when a new air handler, radon system or other appliance that uses inside air has been changed or added.

Golden Pellets are doug fir?
 
I move it all the time, at start up, shutdown and adjust it to the most efficient burn with feed rate. In answer to the quality of pellet yes they are Doug Fir.
 
Is that your normal burn settings? Try changing your adjustments. Have you tried another brand of pellets to rule out changes in Golden Pellets formulation ie just a bad batch?

How old is the stove? When was the last time door/hopper/ashpan gaskets were replaced? Beyond that, are your control knobs for feed/combustion air still adjusting as they should? They can develop weak spots and need replacement. Local electronics store may be able to help if that is the case... If board is suspect, these folks may be able to help www.pelletstovepro.net
