Thermostat controls

PostBy: JKinPA On: Sat Dec 05, 2009 12:53 am

Hi all,

I can't find my instructions and was hoping someone here could help me.

I have an alaska stove with a thermostat unit on it. There is a knob above that says T'STAT and a knob below that says Idle.

My question is which is the auger speed and which is the blower under the chute that the coal slides on?

I'm not burning about 30% of my coal and was thinking if I slow down the feed rate (auger) and increase the blower I'll get a better burn.

If it is like the one I have it only controls the feeder. The Tsat controls the amount of coal fed to the hopper when the thermostat calls for heat. Once the thermostat is satified the stove goes back to idle mode which again cuts back on the amount of coal fed to the hopper. You adjust the Tstat to avoid over shooting the thermostat (rather difficult to do) and you adjust the idle so that you try to avoid the stove cooling down and under shoot the thermostat. I belive you combustion blower runs at a constant speed regardless the control is set at.

That sounds about right although on my stove I adjust the idle to avoid burning too much coal while not calling for heat.

On my stove the auger runs at a constant speed. The thermostat is just a timer. It runs for a longer period of time in a given cycle at higher settings. I have a separate rheostat for my combustion blower. Circulation blower runs on demand at constant speed.
