So I finally got this thing together and fired last night. Had to have help getting it lit but my dealer is my neighbor and came in to the rescue. So this thing is replacing a Central 8460 outdoor boiler so I have high expectations to say the least. My other experience is a 165k Amaizing Heat corn boiler so I was expecting similar run operations? I set the blower fans about 5/8 open and not sure on shovel screws but fire was about 3" from the end of shelf. Woke up this morning to a warm house but boiler temps were down to 140deg and I have it set to 175 on 185 off so it was not keeping up and I am burning a lot of coal. There was a lot of condensation (just soaked) on the lid and all in the hopper which is not a good sign. I have a power vent and it was running wide open so apparently can not keep up with those blower fan settings and my barn smelled like sulfur bad. Also stack temps were around 150deg. So Eric (dealer/cousin) came back down this morning and he adjusted my settings the way his furnace is set up and turned the blower fans down to about 1/8 open. The flame went way down and turned more blue, I could turn the exhaust blower down to about nothing and I was expecting much. The boiler temp slowly and steadily started to rise and exhaust temps went down to about 92deg. Went to town and came back about 2 hours later and no sulfur smell and no condensation in the hopper. Temps were at set operating temp and was cycling off the idle timer! So does it sound like I'm on the right track with the settings? How do I get more power out of this thing if I need it? I did burn 4 40# bags in 24 hours so not happy about that and hope it goes down considerably since the wind hasn't been blowing yet. It was down in low 20's last night but I just am not impressed with output so far. I also have A LOT of unburned coal. Eric thought slowing that air down would burn more of it but will have to see. I'm going out now to sift through the ash to get a accurate count on unburned coal now. Will report back! Oh, my system pressure is 20-23psi....any way to lower it or is that ok?
Please advise!
Please advise!

Another thing I should add is the digital hydro stat is about 20deg off from the analog gauge next to it....I believe the analog and it jives with the analog on the return????

Ideally the return leg is generally somewhere close to 20 degrees colder than the supply leg. 20 degrees is the perfect case.swyman wrote:Another thing I should add is the digital hydro stat is about 20deg off from the analog gauge next to it....I believe the analog and it jives with the analog on the return????

Why is your supply air to the combustion fans practically shut off? Yes you will get a little unburned coal at high outputs but if you shut off the incoming air you will make that worse.

Looks great Swyman!swyman wrote:Another thing I should add is the digital hydro stat is about 20deg off from the analog gauge next to it....I believe the analog and it jives with the analog on the return????
The ash your showing looks about normal for a coal stoker. I'm not familiar with the L.L. but typically with a flat grate stoker, you want something like 1" to 2" of ash on the end of the grate after constantly running for 30 minutes. That's how to set the feed rate.

Can I recycle the unburned coal? Meaning will it burn? This pic of the fire is with this setting in the other pic

No, you cannot recycle the coal. What looks like unburnt coal to you is actually partly burnt coal. It may burn again, but not very well and will likely cause outfires if you put it in the hopper.
It looks like you are not running much air, why is that?

I ran it all night and came out to boiler temp at 140deg this morning. Had fans open over half way and power vent fan was wide open. The barn smelled like sulfur really bad and my hopper looked like you threw a pail of water in it, was very wet. My exhaust stack temp was 150deg also, Dealer came down also and he set it up this way and my boiler temps came up and stack temps went down plus I slowed the exhaust fan down to about nothing. His theory was by running it slower, had more time to (absorb) more heat. Seems to be working for now but I don't think there is any way it will keep up when the temps go to zero and 30mph winds. I need to be able to get more heat out of this thing but when I turn up the combustion fans I get moisture in the hopper and sulfur smell in the barn??? suggestions please!!!!!StokerDon wrote:

Make sure the hopper lid is tight fitted you are piling coal so the lid will not fit - not good. Damp in the hopper the stove is exhausting through the coal bed and a sulfur smell may be the beginnings of a hopper fire. What does your manometer read, I am sensing a low draft. I agree do not recycle black coal that is partially burnt. The stove is not breathing!

They sent this cheesy Dwyer manometer that seems to be a hand held model with no good way of attaching it to the unit so I am waiting till tomorrow to call Matt at Leisure Line to answer some questions. I think I will have issues because it seems the power vent I bought with the unit will NOT keep up with the combustion fans running past 50%? I'm doing another 24hr test with the settings where they are at now and see how much I burn and if it will "keep up". Just using the draft damper set at 4 for now will I call the company.

They sent one with the unit but is in a drafty barn so didn't think I would need one?lsayre wrote:Be sure to get some CO detectors installed right away.

They are always needed, but doubly so if sulfur smell is evident.swyman wrote:They sent one with the unit but is in a drafty barn so didn't think I would need one?lsayre wrote:Be sure to get some CO detectors installed right away.

Matt is the man to talk to but let's get some info. A photo of the Dwyer and what powervent model are you using. I don't like the information our dealer is giving you. In the shoulder season we all struggle a bit but super efficiency is not what you are trying for here as a newbie. Drafty barn or not in most places CO detectors are the law.
