    How many scrape the pot of there bottom feeder (gonna say most everyone is a Harman owner besides my Enerzone here) ?

    I have been going as long as 2 weeks without touching the stove. At all. No scraping, no cleaning, no nothing. After this last torture test, I am ready to try and go at least a ton before touching it. Never done it daily. Just let it go to the weekend.

    The reason for this post. This stove self cleans with great ease. The pot isn't quite flat, but only has a very slight slope from back to front. So all the crusty ash/clinkers get pushed right over the edge. Was wondering if the Harmans act the same way? I have seen numerous pics of the Harman pots and it seems the slope angle of the pot is a little greater?

    Here are a couple pics (different days) of it burning. Notice the large clumps about to fall off. When the stove calls for heat, it pushes a bunch of pellets out and these clumps fall off the edge.

    My last 2 seasons, I have burned about 2.5 ton per season. But they were pretty mild winters for our area. I am almost at the 1 ton mark already, so I am pretty sure I have well over a ton to go in the new Enerzone. With it having the ability to do High/Low, coupled with the fact that it's a new stove and I want to use it more. So I will be burning more pellets this season.

    Just did a good cleaning and finally emptied the ash pan. After what I have burned, I am 100% sure it will take a ton in the pan. The pan isn't visible because I intended to do this test 1st. I still have a lot of room to go before that area would be filled, but wanted to do this small test 1st. I didn't want to get into this 1 ton burn and find out almost half way through, that the stove/pan couldn't hold it. The pan itself is very large and then add the area from pan to pot.

    So, this is a question thread (on who scrapes and why)? And also my 1 ton burn thread (or longer ;) imacman) this stoves has lots of adjustment for air. It was designed to burn the highest of ash pellets out there (maybe Fyrebug can elaborate) and do it with ease. After hearing the torture tests that SBI put it through? I am positive it can do it. (I hope) It also has the best air wash I have ever seen (open on all 4 sides) So the glass will stay clear enough to track progress.

    Looking forward to the coming month :)

    Here are the pics of the stove, pan, clumps that get pushed over, and finally clean pan/stove. I did scrape the carbon from the pot and clean it before I was truly finished.

    Dex, what are we looking at in the 5th, 6th, and 7th pics? Is that the ash pan? How many bags were burned through it since the last time the pan was emptied?

    Yeah 5 & 6, that is the pan pulled out, with leftovers that were scraped off the top of the pan, left in the bottom of the stove.
    And 7 is just a visual of the clumps in the pan and what was scraped off when I pulled the pan out.

    This was 41 bags IIRC and I still had about the same amount of room left (filling firebox up from level it is at, to bottom of pot). So going another 9 bags shouldn't be an issue.

    Not gonna do anything special. Stove still runs daily (during the day, it is all that runs). If I run the Fahrenheit, it doesn't get started until about 6pm and it's run in manual mode (level 1 last night), and the Enerzone runs on/off if more heat is needed (was on when I woke up at 5am).

    I posed the scrape question to others, simply because when the stove is running in "High" or about 33% output on the cursor, there is no difference in flame. Only time the flame looks a little different, is when the stove burns in "Low/Maintenance" burn for an extended period. But once it kicks into High gear, it looks beautiful again :)

    This is after 3 days of non-stop burning. I'll scrape it and knock off the fly ash before I head off for work. I just did a full clean on Saturday with this cold snap coming through this week.

    I've gone 7 or 8 days without scraping the pot and this is as bad as it gets with the LaCretes.

    Dex you are correct the Harman burn pot has a steeper angle I scrape mine daily ,but it still gets a speed bump down in the bottom. I cleaned it this morning as a cold snap is coming . There was a pretty big bump in there today all cleaned out and back on line:). I think that last year I ran about 50 + bags before I cleaned , that was at the end of the season, no issues just takes longer to clean.

    I think it is close to a 1 1/2 - 2" difference in height from the auger to the edge of the burnpot. I scrape a couple of times a day, just out of habit. It looks better that way. I'd rather look at the flames instead of the ash.

    I am pretty sure mine only rises about 1/4"-1/2" from back to front. Just enough to keep the pellets from rolling out ;)

    My old Englander is bottom feed. But it couldn't push ash out? Has well over 2.5" to push up. It may keep burning, but it's not self cleaning/pushing over the edge.

    2 days in :) Runs High/Low during the day 7am-5pm. From 5pm- am it runs On/Off. Only kicking on if the Fahrenheit can't keep up on level 2.

    That's a heck of an ash pan. Can't tell if its as big or a bit bigger than the Fahrenheit pan.

    Looks like you've got a nice stove there.

    It's a little smaller than the Fahrenheit. Only because of the Horseshoe in the back. The Fahrenheit has a 5 gallon bucket for a pan :) this one is only 4 gallons ;)

    3 days and 3 bags :) Lots of ash today. But it will soon meet its demise (into the ash pan) ;)

    1st bag was Presto and last 2 have been Sets.

    The longer it's in low burn, the bigger the ash chunks get. I'm home today, so and I just turned the Fahrenheit off. So it will be running on High a lot more today. Should clean up in a few hours. May turn the combustion air supply and exhaust air up a couple % each. To help rid the ash on Low.

    I'm with subbie on this. I tend to do a quick scrape and clean the ash on each hopper fill. Seems that with the air holes cleared, I get a stronger more blow torch like flame. But as my stove is in the basement, all my stove tools are sitting right next to it, so its very easy.

    Also Dex, consider getting one of these if you dont have one, it works great for breaking up any building carbon. I use it for a good shut down cleaning as well as a hard scraping of the pot every few days while burning. Only takes a few seconds.

    I will take pics in a bit. I hung a key holder on the back of the stove. Holds all of my "go to" tools.

    As for the scraping. My pot has a series of holes where the ignitor is. Most combustion happens there. Rather than the rows up near theend of the pot

    Hi Dexter

    Nice thread, I was thinking of making a thread like this but you beat me to it! Just soo busy with parts and service!

    The Harman DVD says to scrape the pot to prevent carbon buildup by tucking down the hot coals after the ash scrape. That is the reason I hear.

    I have been doing it daily with the hot coal tuck and no carbon buildup so far.

    Here is the key holder I hung to hold the tools I use the most and also a pic of the scraper (both ends are sharpened for scraping)
