Thermostat Installation, Fuel Additive

THERMOSTAT INSTALLATION

•The American Harvest can be installed with and operated by a wall-mounted thermostat (Optional WT47) which may be purchased from your dealer or from USSC. The wall thermostat needs to be for a low voltage system. Most thermostats will have instructions with them as to where to place them in your room. Please follow the thermostat manufacturer’s instructions carefully.

•There are two (2) male spade terminals on the back of the control panel near the center. Connect the two wires from the wall thermostat, one to each of these spade terminals. Needed: 2 female ¼” insulated terminals.

•Make sure that the wires are routed to protect them from hot surfaces. Do not cross wires with circuitry on board.

•Make sure the unit is disconnected from the wall outlet before working on your unit. The circuit board is located on the left side of the unit. Remove the ¼” hex head screw and pull circuit board towards you. Lift the circuit board out of the housing. Do not crimp or stretch the wires leading from circuit board pigtail.

•Reinstall in reverse procedure.

It is a good idea to use the thermostat option to achieve uniform control over your heating needs.

If you are gone and the home requires heat, the unit will automatically resume the high setting when the thermostat calls for heat.

FUEL ADDITIVE

Chicken Scratch for my Corn Burner?

Yes - Crazy as it may sound, ground Oyster Shells, same as feed to chickens, is the ideal additive to promote clean burning, especially when the Corn Fuel is extra high in starch. And it’s available at your local Feed and Seed.

The “average” mixture is 1/2 pound of Oyster Shells (about 2 handfuls) to 60 pound of Corn, a full hopper. IF the “fingers” on your agitator (stirrer or rouser) have a noticeable buildup of “clinkers” or stubborn deposits, you have either a high starch fuel OR are burning with too much air for proper combustion and are reaching the “fusion” temperature of the Potassium and/or Starch in the Corn. You need Oyster Shells - and maybe more than a couple handfuls.

If you notice a heavy accumulation of “whitish powder” in your burn pot, reduce the amount of Oyster Shell Additive.

Remember, using this additive- as necessary - promotes efficiency (higher heat output), reduces maintenance, clinkers and ash content.
