what Leafmold is writing about is called "overfire air"....air channels up over the fire from the igniter chamber.....theres only two Harmans with this.....The Accentra Insert, and the P68. The rest of the line might have the holes, but they dead end into the stove body. Originally, this post was concerning smoke in the hopper. In the rare instances when we see this, its usually indicative of partial combustion of pellets in the auger tube, prior to the fire.....what happens is a residue gets slowly depisited on the cooler surfaces...its sticky, and accumulates, as well as forming a matrix of fines and a tarry substance inside the auger tube, inside the feeder assembly, on the slide plate, and in the lower portion of the hopper. It'll chug along for a while like this....maybe a couple months, maybe a couple years, until the accumulation gets so heavy that the slide plate seizes and the stove wont feed pellets....sometimes destroying the gearbox on the process. its a pretty big job to clean out, but its possible. Any units we've cleaned we've had to remove, take tot he shop, clean it or replace the feed mechanism, and reinstall the stove. Probably too dirty to do on-site by the stove shop. We've also modified EVERY stove we've done this to, and have yet to see another gum-up on a modified unit. I dont elucidate on the modification, because it does entail drilling of the feeder, etc, and I dont want to see anyone screw up their unit and void the warrantee by doing a "home fix". I also dont want to be liable if they really screw up and have a fire, etc.
