I am selling my 2003 LMF BM 620-9 with LDJ 165000 BTU mod for 1/2 of the current new price of the BM 620-9. The unit is in very good working order, and like stated has the LDJ 165000BTU mod. This give the furnace a continuously adjustable output from 62000 to 165000BTU, very handy in the fall and spring. They ran a natural gas line down the road and since my job can keep me away from home for a week at a time I have decided to sell the corn burner and burn natural gas. I was going to put it in the garage, but it is worth too much to heat the garage a few times a year. Photos available. Also have a 140 BU gravity box and a 4 inch auger.

Nice hot air collector.. hows is working? I am building some MTD collectors for heating water. Small at first to test it out. But plan on big latter. Thinking about getting a Lacaster corn stove to supplement it. We have a LMF/LDJ 165K BTU variable furnace but it does not do well with low or variable heat loads and solar would defiantly be variable. Hope to not run it at all in the fall and spring in the near future.
Here is an awesome DIY solar link.

Americas heat has them online. This should work for a plane Jane 100K unit..no variable settings. But be careful as there may be slight differences.
Kevin

That is a lot, ours is a LMF 100K unit that was upgraded to the LDJ 176K specs. we burn 14 BU in 8-12 days in west central WI. House is 8 yrs old and 2700 ft including the basement. I would call LMF directly, he is burning up money!

Kevin

I think your speaking about the circulation blower and not the draft blower. I had the same issue and I raised the temp setting on the blower control slightly. This also made the air from the register warm, as the low temp air was cooled by the run through the basement.
I have mine connected to a thermostat, but if you just use the on/off timer to control heat you may want to leave it or not? Of course you should consult the MFG before changing anything.

Kevin

No ideas?

Hi every one, I am a little sad to say that I have to sell my biomass furnace. It is a 2002 Americas Heat 100,000 BTU unit. It was upgraded to the LDJ 165,000 controls in 2004. It is variable from 62,000 BTU to 165,000 BTU by setting alone. It starts in the fall and burns all year. It is in very good working condition.
I do not know what to charge for it, what do you all think? It is in NW WI.


Thanks

Kevin

So there is draft into the burn pot auger? How is this plumbed on the draft blower side?

Thanks, but I was asking about the corn combustion fan settings, where it is very important.

Kevin

Sorry I meant combustion air settings for each BTU setting, ie. 1/4 open, 3/4 open ect..

I think I'm going to try these settings, but they will have to wait till the week end so I can be sure to monitor the results.

Thanks

Kevin

What is the recommended draft setting at each one of the settings? This could explain a lot of irregularitys with my furnace. I run way more draft then MY instructions advise, but if I don't the corn over flows. But my settings are running a lot more corn then yours, so this makes sense.The pvc must have restricted it enough to work OK, but the new AL tube does not.

Kevin

Interesting, I assume that you are not running a thermostat from the low fire settings? If I try those settings I heat up the house too much, unless its below 20F or so. I have attached a table comparing your settings to mine. It also shows the settings from the installation manual and from the updated ones they sent me. This is from about 2005/2006. They did not include a 65000 btu setting but I have settled on one very close to what yours are.

Kevin

I don't know what the airflow on both sides is but I have an LMF furnace with a LDJ 165kBTU conversion (corn only) my low fire timer stays at about 1min on and 12min off. I am using a thermostat and what is listed on mine as 90K BTU of 1.5 on and 1.5 off. I would be interested in your timer settings as listed by LDJ. Mine are 165k 3on/0off, 132k 1.5off/3on, 100btu 2on/1.5off, 90k 1.5on/1.5off, 80k 1on/1.5off.

The BTU mod adds a high fire max time and a new auger timer, so you end up with a max high fire timer, a high fire burn rate(BTU) timer and a low fire timer. Plus you change the auger motors to I think 4 and 2 rpm from 2 and 4 rpm (from memory on the rpms, but you get the idea) Sounds confusing, but you end up with a separate control for high and low fire and still thermostatically controled. The high fire max time is so to keep you from going full out all the time. I put a new aluminum feed tube on this fall and now it feeds too much corn for my air settings. The PVC tubes must really restrict the corn flow. The BTUs are infinitely adjustable now with in range, though they print up a chart showing 80K, 90K,100K, 132K and 165K BTU settings. The only time the low fire timer comes into play is very early and very late in the year and even then I can turn the high fire timer to below 80K and the low fire to 1min and 12min. But this all assumes that I'm home to do it all. The windows get opened a lot when I'm not around during these times. I have never went beyond what I calculate to be 115 to 120K BTU, that was a few years ago, breezy and -35F. This year I went to 100K for a couple of days, but I have no idea what my new flow rate is. I'll have to check it out when it gets warm, so that I have it nailed down for next year.

It would help if you would put an explanation of exactly what this thing does. I have had one of your furnaces since 2002. It has worked well, though I did upgrade ours with the 165K BTU option from LDJ ( yours was not yet available and NW WI winters made this mandatory for our house) This setup has been working well, but is is and inexact science to set up a perfect burn when using a thermostat and varying out side temps. To make it worse. work takes me away from home for a week at a time on occasion and I'm sure my wife does not even try. This gives me no end of worry while gone. Could you post exactly what this thing does and what it controls. Your website has a brochure, but it does not have a single detail. A install, operations manual would be a nice start if available in digital format.

Thanks

Kevin

Any one here have a Corn-Trol I am away from home now and then and I worry about the adjustments when I'm away. Seems this would do the trick. My LMF has the LDJ 165BTU mod so I guess it would replace them?

Kevin

Ya, but for a few years there I could rub two penny's together and make change! Still better then the alternative and I hear even Nat gas is going up.
Kevin

Nope, just cheap!

Kevin

I have an LMF with the LDJ variable added on. At 90K BTU setting I have the draft almost wide open. I do use a thermostat so that may effect it. The low fire is set to 2-12 and .03" water draft. The flames hit the deflector. Turned up to 100K and wide open this morning as the temps are going down hill.

The manometer is very important to get good low fire to work properly. I have my low fire timer set on 2-12 and it works from 45 f to -35 ( coldest so far) It does have an LDJ variable heat output mod on it though, so I can turn the BTU down to 80K. ( would not heat the house well past -25f).One down side to the LDJ mod is it has a timer for max high fire adjusted to 10min. So when lighting you have a delay of 3 min before the augers start. Unless you turn the off time to 0 for lighting.
This thing is also tied to the heat pump for late spring and early fall and it is getting kind of control "overdone", so I'm thinking of scraping all of it and using small PLC instead.
