Is this an alaska maybe? The guy selling it says he couldn't find a name on it. I'm going to look at it tomorrow, but if anyone knows what brand/model it is first it would be helpful.

i don't think alaska ever used a door like that. i could be wrong.

could be a triburner or a keystoker.

have the seller send pictures of the grate and stoker mechanism.

Thanks, he's close enough I'll be taking a look before I bother him for more pics, although I should have asked initially. The door actually matches what I see on older liesure line hyfire's, but I don't see any with the stove shape as this when I image search. I'm just looking for a cheap shop heater.

Looks like the older Alaska Cast Console style, but a little different. could be a knockoff of semi home made. ? hard to say.

That is a mystery stove. It looks very much like one of the old Alaska console stoves but the doors look like Leisure Line. I suppose it's possible that someone swapped the doors, just to make it interesting.

Well for $250 the stove, along with 1/2 ton of rice coal is mine. The blowers run, the steel is solid, and the gear motor runs. Looks like it comes with a speed control for the gear motor, as well as one for the convection blowers.

The only ID I could find on it was patent #4,537,140 which apparently was created by a Charles Baker. This is going in my workshop, hopefully I can get it running good for my needs! Any advice would be appreciated, I have a keystoker in the house. Not sure if I need a barometric damper for this guy.

Ignore that white piece above the grates, just the bottom of a coal bag I had set in the hopper.

It's a Tri-Burner carpet feed type stoker. It probably is an Alaska. These are real common and pretty easy to work on so you did well!

Yes, you need a baro damper unless you want your heat going up the chimney.

nice!

if you want better efficiency out of that unit, convert it to a separate combustion motor setup.

all you need to do is remove the fan blade from the stoker motor and add a 50 cfm bathroom vent fan for the combustion air.
that also allows you to run a digital coal trol on the stove.

Thanks guys! That's great to see those mods. I think I'll see how it runs as is for now, that separate blower sounds like a great simple improvement though.

search user Matthaus posts for mods on the triburner style of stoker. he is the one who gave me the idea and he even came to my house and gave me the fan and set it up for me.
(Matt is one of the leisure line owners now) i may have some pics of the setup on my posts too, i do not remember. if you need any assistance feel free to ask, i'll do my best to answer.

i tried other fans on my alaska stoker but they were noisy, i found that 50 cfm vent fan motor to be the quietest and only around 14 dollars.

the problem with the triburner stoker is if you lower fan speed you also lower combustion fan speed.

run the motor at full speed and use the adjustment on the stroke arm to adjust coal feed. you will have to adjust this manually to control temps. i used mine for 2 seasons like that then in 08 matt hooked me up with a coal trol. they are not cheap but worth it....it will pay for itself in a few seasons in coal savings.

Can you elaborate how the damper will help with efficiency? Not that I don't believe you, I just want to understand it better. Is it that when draft is high (max feed) it will pull all of your combustion fan air quickly out the chimney instead of letting it stay in the chamber and heating the steel longer? I'm running it today just trying it out with the pipe I had on hand, and it's burning great, but anything that transfers more heat to the room would be even better. Currently using my infrared thermometer I'm seeing 450 deg. on the front just above the door, 150 on the top surface above the convection airspace, and 150 on the surface of the stovepipe.

Thanks that's how I'm running it currently, no rheostat, just adjusting the feed screw. I'm running it full tilt for now, hot coals almost pushing into the ash bin.

I know I'm a day late and a dollar short.... but the stove in the original post is a Leisure Line Patriot model. 90K btu with dual fans, one on eaach side in the back on the bottom. This stove was made in 1996 and 1997 I believe.
