After a short heating season last year I decided to clean my Harman Accentra Zero Clearance insert. I got it installed last February and burned maybe a bit over a ton but not much more then that. Mostly PureHeat hardwood from my local Menards here in Kansas City.
After a watching Harman’s and other videos I was pretty confident I could do it, after all it is only a stove. After cleaning everything I could through the front my confidence was brimming over as the videos were pretty much spot on.
On to removing the insert from the cabinet. Service stand adjusted and installed I unlatched the stove and slid it out from the cabinet. Surprise the back didn’t resemble anything like I saw in the videos. The fans were all squirrel cage types with no resemblance to the video. I spent a couple of minutes looking for the clean out to the feed system. Once I found it hidden behind the combustion fan motor the trick was getting to the wing nut to remove the cover. Thankfully 30+ years of fixing 737’s has thought me one thing. If I can see the fastener I can remove it or tighten it.
After snaking my hand through the bowels of this stove I was able to touch the nut and get it loose enough to remove the cover and snake the vacuum extension up to clean the fines and pellet bits from the clean out. I vacuumed out all the squirrel cages and any other areas.
On to the flue. Got my fleet shaft thingy and three inch brush up the flue hole with it. I could not believe the amount of stuff that came out and kept coming out. In out in out stuff kept falling out I scrubbed till no more came out. I did notice I couldn’t get past the 90 in the flue to the exterior wall. I didn’t want to push to hard so I went outside and tried to push past the 90 and still could not. Any suggestions on getting through that 90 would be greatly appreciated. I’m still a couple weeks away from operating the stove and would like to push through that 90.
I kept my vacuum outside when and ran the hose through the window. I ended up with about 2.5 inches of fines fly ash and ash in the bottom. I’m thinking this insert will have to be cleaned every 3/4 ton of pellets. From now on until further notice.

). However, I don't do the linteater thing every pipe cleaning - just at the end of the year and maybe in the middle of the season for the P61 which is the stove that goes thru 4/5 of the 5-6 tons I burn a year. I usually use the Leaf Blower Trick (LBT) though, and use it after the linteater too. Not sure how your set up is, so the LBT may not be practical if you go thru the roof although I know some people make that work.
