I have the notorious Harman gummy stove issue in the feed area of my Pre 2009 Accentra Insert. I know what the problem is and right now I would just like to know where the most creosote buildup occurs in the feed area, thus jamming when it trys to feed pellets. My guess is that it's in the area just above the auger where the pellets drop down that angled chute through the rectangular opening in the auger tube. I'm thinking it's most likely where the combustion gasses are backing up through the auger tube and condensing on the colder surfaces of the pellet drop area just above the auger. Any suggestions from those that have actually seen the buildup in that weldment would be most helpful. As a short term fix I plan on making a right angled tool from a very long screwdriver to go up into that rectangular area above the auger and scrape it clean to see if it helps. It's only a short term fix because I'll soon be removing the entire feeder weldment to give it a full cleaning, (I've read that boiling water will desolve it) and adition of the Crossover Air Tube Kit that corrects any creosote buildup in the future. This issue all started just last November after 15 years of trouble free use. Thanks.
