Hello Fellow pellet burners, i have a three year old Harman pc 45 starting to act up? been having a lazy flame lots of soot and even more then normal smoke going out the pipe. so far i changed all rope gasket seals top door and bottom door and still the same problem. i checked dust door to make sure it was secure. im running as i type this its making enough heat but something not right. im burning somerset pellets and am in room temp mode with only on 3 auger setting as any faster i have pellets not burnt dropping in ash pan and even yet they are not burning up like normal. any ideas? thank you in advance!!
