    I am scratching my head as why the carbon is building up so fast in the burn pot. No settings have changed. I was able to go 10 days before a cleaning was needed with Lignetics. Now with somersets , I am lucky to get 3 days, and the buildup is some hard carbon, I literally have to chip it out. The stove has had a top to bottom cleaning twice so far for every ton burned, and then of course I do my weekly cleanings. I just switched over to greenway, and it seems like it is going to do the same thing. Tomorrow I will clean it again, and then burn the last of my lignetics to see if it is pellet related. Once the carbon builds up you can hear the agitator grinding against the carbon, so I always shut if off so I do not break the bushing or pop the fuse. Not a major problem, it is just a inconvenience.

    We have burned 2 brands of pellets so far. The second one required almost daily pot scraping. That said I heard we use more bags than most... There was alot more carbon and it was more difficult to scrape, litterally had to break it up to get the pot clean. The second brand also created other inconveniences, glass sooted faster, auger had frequent jams, and the ash pan caught on fire while dear husband was traveling :hair:. Glad the majority of our stock is the better brand :)

    Not sure if I could have adjusted the stove to burn the other brand better, I knew we would be back to the pellets that burned well so I did not look into adjusting it.

    Depending on how much you burn, I don't recall how much you bought, it could be worth seeing if you can adjust something in hopes that your stove burns the new pellets better.

    Could be the colder air temps? I have to chip a bit of carbon each day as well.

    Different pellets produce different amounts of carbon for me. Normally Hardwood will produce more for.me than a softie.

    Colder temps if you have an OAK may effect it, also every pellet bur different and will need the damper readjusted.

    In my opinion Somersets are better than Ligs, but I have only burned a few bags this year and it was not a good test. But the 6 years I have burned Sets, they were a phenomenal pellet

    You know to be honest that is one thing I never messed with is the damper adjustment or the feed and and air trim. The stove has always burned great, no creosote, just fly ash and so I leave it be. The dealer set the draft with a magneholic gauge, and so I leave it alone. I think it is just a difference in pellets like you said. I am having a different experience with Lignetics, they are burning hot and one of my favorites. I would put them up there with somersets, minus the fines. But I know we all have different experiences based on weather and setup. I do value your opinion, and I thank you!.

    I get some carbon Build-up from the sets as well (I believe our stoves are basically the same), but not enough to interfere with the agitator. My problem is my agitator only lasts about a season and a half before the tines get cooked.

    That's probably what you'll see is its pellet related. I find that Stove Chow effects my stove with carbon build up more than the MWP or AWF that I have been burning.

    I drilled some extra holes in the burn liner to reduce the build up by the igniter area as it was the most effected zone. And where the build up seemed to interfere with the agitator the most.

    Then I drilled a few holes alone the back where I noticed more build up.

    I'll post pic's of the burn liner next time I have it out. But after drilling some extra holes I can easily go 2 weeks(or more) before I hear the beached whale grown noises. In the second picture you can see how the carbon built up around the stock middle slot under the circled area. But in front where there is no air slot or holes the carbon build up is far worse.

    Your liner is different than mine, So it may require drilling holes in different locations than where I needed to drill.

    This pic was after I drilled a test hole to see if more air would help. Notice there is no carbon where I drilled the hole.

    You get the picture, keep drilling holes(approx 3/32" dia) where the carbon sticks. It should help where the worst build up is. ;)
    Heres what mine looks like now in that area.

    Hey guys little idea here,my dad used to burn a mix of corn and pellets and would get build up like you guys are getting. I'm not sure where he got them but he got some oyster shells and sprinkled it in when he filled the stove and it seemed to help. I'd be interested to hear back if anyone had tried this or had anything else that works? I also made him a couple steel agitators used for mixing the pot,made one out of stainless as well because they were wearing thin!

    Oyster shell is commonly used when burning corn to reduce clinkering.

    I just heard back from dad and he said that the stainless agitator is getting a lot less build up. Anyone need one made up?

    I had some carbon build up with Mixed pellets, but with Blazers, nothing since I turned the stove to 3.

    Apparently the feedback from Somersets this year is, We ran a lot of Hickory flooring, so there is more ash, but they still exceed premium grade. I also see a lot more carbon from this years sets.

    Yes i can make that it looks like it is tapered on the ends? Is it a clearance issue? I might have to have you cut the end of the old one and send it up so i can weld it on or re fabricate it. Looks like you have a spare at least
