Does it matter? I don't want to mess up the controller by using a wrong one.
I've got this in the basement testing it. It starts easy and will get up to about 450 then it starts drifting down to 200. I just have the thermostat wires twisted together
so not sure why the temp would be reducing. Definitely need a thermostat I'm not sure which one to use or even if it matters.
When I untwist the thermostat wires the whole thing shuts down. Blower, auger...everything. It's like I turned the switch off. I would have thought it would just go into an idle mode???
Which thermostat for a Firetender/Moutainman stoker?stoker

My stoker is in idle mode whenever the power switch is on. "Idle" is adjustable I have it set up to run 3 minutes every half hour. This keeps the fire going.

Does the blower run outside of those 3 minutes or just when the auger runs?carlherrnstein wrote: ↑Tue. Dec. 24, 2024 10:36 am My stoker is in idle mode whenever the power switch is on. "Idle" is adjustable I have it set up to run 3 minutes every half hour. This keeps the fire going.

On mine there is 1 motor that operates the auger and the combustion blower. You don't want combustion air without coal being fed because the fire will burn down into the tuyere. You want the coal to burn at the same rate that it is fed in. You make the coal burn faster by increasing the combustion air, you slow down the rate of burn by decreasing the combustion air. There's only a small window of adjustment, and sometimes can be difficult to get the airflow set without having coke trees.

Do you clean your coal? The coal i have has a lot of fines in it. I've just been using it that way. The coal that was in the hopper when I got it looked even worse. It just looked like dirt.

I don't do anything other than dispose of my own used motor oil on my coal. This prevents the coal from freezing together in a big mass when it gets wet, store it in an above ground bin but inevitably rain/snow gets on it.
Experience from 12 years has taught me that a whole lot of fines (more than 50%) can cause loud creaking noises but no major problems. The fines get packed around the auger towards the gearbox and kinda jams it somewhat, it never caused anything worse than noise.
The manual for my stoker recommends 1/4" bottom size and 1" top size with a maximum of 25% "fines"

It seems.like the flame is only burning around the edge of the pot and not much in the center. I see alot of fines in the center so I thought maybe it was an issue.
I might need to screen it. Some of it is larger then an inch. It is quite soft. I was just hoping it would break it up. It's kind of wet too. I just have it on a tarp on the ground and covered with another tarp.

There's been a couple times that I have had fires go out and the problem was 3-4 large roundish pieces of coal (chicken egg size and shape) riding on the screw blocking smaller coal to get to the screw.
Lots of fines? Is it making lots of popping an grinding noises?
I had a problem with lots of fines when I first used my stoker, the screw was severely worn and was grinding the coal to fines when it was feeding. The coal would go in in pieces an by the time it got to the bottom of the burnpot it was mostly dust.

Yeh there is some popping noise but I don't notice any grinding noise.

Maybe run it out of coal, clean it out, screen a couple buckets, an run it into the burnpot an see if it's turning to fines in the auger.
If it were colder I'd post a picture of my fire with the stoker going. It been very warm lately and I let my stove go out, it hit 68 here today and any fire is too much. Often when these small stokers aren't running consistently during warm weather the fire doesn't act right and might make lots of coke, of your heating demand isn't high that might be part of the problem.
