I need some help, I just installed a comfortbilt hp50 . when its running, it will take off like a freight train, then die way down, then take off again! the flame is never lazy and it is always a good color, it just races and then drops to almost nothing. On levels 1-3 it drops down to coals only dumps pellets, sparks fly and then it takes of again. I can actually hear sucking air when it races. I can also smell smoke on start up. The customer service has tried but no good, the numbers they send me to adjust feed rate dont seem to apply to my stove, so I set all settings back to factory . also, the damper does next to nothing to the flame, it will burn with the damper completely closed. Any advice?
