Make sure the tunes in the exchanger are clean take the top off and look down the tubes with youre own eyes and check them dont asume the brush did it. I fought with mine half a year till I did that I would push the brush though and then I looked with my eyes and only had a 3/4 inch hole though them hard build up over 4 years if it can't breath it will be full of popcorn and pot will cover with had build up and even get red hot

that sounds just like my boiler did last year before i got the tube really clean if it can't breath the water doesn't get hot enough so the aqua-state calls for heat the heat can't get out so the corn starch get really hard plus it doesn't breath good so that is where the popcorn comes from not enough air you just need to make sure the tubes are clean and don't take for granted that the brush is doing the job look though the tube with you're own eye

I have a 100k boiler also I can't tell you enough to make sure flue tubes are clean I know this sounds wrong but last year I fought with mine half the year was on speed diel with Mike in Wisconsin finally i shut it down are removed the top to look down the tubes they were 3/4 plunged and the brush didn't clean it out get a 1 3/8 hole saw and add a 20 inch rod to it and use a drill to cut down though the tubes to get them clean will make a Hugh difference burned lick new again hope it helps

Dan 59 I am burning a ldj 100K boiler and last year was my 4th year I was about to yank it out last year till I found the problem I was just like you couldn't get it to breath I keeps cleaning it the brush the tubes in the exchanger fire it up a day latter same problem finally I pulled the top off the boiler and brushed the tubes again and realized the brush only cleaned a 3/4 hole and it would fill up in a day I took a 1 3/8 hole saw and cut it down threw the tubes to get them open all the way to 1 1/5 after that it ran like new again so make sure tubes are really clean not just think so because you ran the brush though them

I have found out this year that you can't always push that brush though the tube and assume they are clean, I have fought with my boiler all year finally took the top off and did a visual down the tubes only had a 3/4 hole though after cleaning with brush not good, took a 1 3/8 hole saw made a 22 inch shaft for it and run it though the pipes cleaned them out great, boiler is running like it did when it was new, and fuel usage is less also

thats interesting my ldj boiler came with that valve on the bottom of the tank so you can shut off the fuel

I can't get my 100k boiler to burn worth a crap this year I've tried corn alone like the first 3 years, then tried adding cherry pits, now I'm on corn pellets mix
burns to bottom of pot but the fire box is full of none burnt fuel Styrofoam looking pot red hot only burned 24 hours since cleaning tubes can't seem to keep top holes in pot clear keep plugging up then i'm all done

Haveing a hard time getting my boiler zeroed in this year fire wants to run really low in pot any one else with the same problem

This is my 3rd year with my LDJ 100K boiler but the first year that it is still burning in April at this rate it might still be hot next fall

Has anyone here ever had to pull the burn pot out of the boiler, I've been noticing that mine is getting loose when I have to knock the klinckers loose that the pot wiggles it never used to' I'm in my 3rd season at about 500 bushel per year would also like to be able to check out the feed auger tube in the pot auger is wore and stepped like the feed tube and the pot tube are not lined up properly

I'm in my 3rd year with my 100K LDJ boiler was looking on here for the info on how to put a timer in so on high fire I can make it shut down a few minutes every so often so the burn pot can cool down if anyone knows witch timer needed and how it get installed will app.

I have it made have 250 acres that is rented out on shares the guy that farms it has a big dryer setup and scales so I just keep 1000 bushel each year to heat and feed some steers just go to his place weigh the wagon fill it and weigh out subtract from total just like the bank cant ask for it much better

I have a 12 volt inverter I use just put a plug on the wire that feeds the cir. pump, then you can unplug and plug into inverter and hook up to battery

Unclear about the reason that you use close tee's in the pipeing looking at the picture above

Just remember the old saying GET what you PAY for, check the specs. on that motor from surplus, it,s only 30 buck for a reason, it only is rated for 104 in lbs torque,the motor 1LNF7 from grainger's is 90 buck's but is a 130 in lbs torque and steel gears not nylon, just saying there is more than the price to look at
my two cents worth:)

Hi all I'm trying to understand what you are talking about with the thermostat it is suppose to be hooked up to the zone valve or pump to control water flow though the heating units not to control the boiler that is the job of the auqustat
I'm in my 4th year with my ldj boiler I run mine at these settings 3 min ON, 10 min OFF, air 1/4 open, water maintains 165-170 have not changed since first year heating 100 year old farm house 2400 sq ft thermostat set at 72 in central Mi.
