I don't get it. Enviro Empress ran great on Okenagon pellets last year. Fast forward to a couple weeks ago. I did the leafblower trick to clean the stove out then lit it for the 1st time just last week. The flame, using the same pellets is terrible. Very orange/sooty and the firebox keeps filling up before the pellets burn sufficiently. I pulled the air damper lever full open and that does seem to help, but you can tell it's too much air. Not sure what's going on, as leaving the air damper where it was (nearly closed) worked great last year. I cleaned out the fans with a shop vac us usual, but just not getting that whitish/hot flame. Any ideas?
