2. The Low Limit Setting: This turns off distribution blower when limit switch temperature drops

below this set point. (Only turns off distribution blower, stoker will still be able to run) Factory

setting is 100 degrees Fahrenheit.

3. The Middle Limit Setting: This turns distribution blower on when limit switch temperature rises to

set point. Distribution blower will stay on until limit switch temperature drops below the low limit set

point. (This only turns on distribution blower. It does not interrupt operation of stoker in any way) Factory

setting is 170 degree Fahrenheit.

• Loss of Draft: This can occur during hot, humid summer weather, with low fire in burner.

Changing the number of minutes of run time per half hour, increasing slightly the coal feed and air set-

tings may help. Thoroughly clean the furnace flue pipe and chimney. Remove fly ash buildup in furnace

by removing clean out plates and removing fly ash from furnace. Check to make sure all openings that

could infiltrate air from furnace base are sealed either by gaskets or seal it right caulk.

• Too much Draft: This is most likely to happen during cold, windy weather where there is no baro-

metric damper installed in chimney pipe. In this situation the fire continues to burn, even though the

stoker is not on. Adding a barometric damper and or properly adjusting barometric damper can help.

Adjust barometric damper so that you have about a negative .05 or negative .06 inches of water column

in your single wall chimney connector between your barometric damper and where single wall chimney

connector enters the furnace. Exhaust fans can also cause this problem by drawing air down the chim-

ney, through the burner and out of the housing inlet. This can be corrected by providing adequate out-

side air openings for both the stoker and the exhaust fan or discontinuing the use of exhaust fan.

Cleaning and Maintenance

• Turn off all power supply or disconnect power cord before attempting any maintenance.

• We recommend that you completely clean out stoker pot immediately after unit is shut off and

cooled down for the summer. Take auger out of auger pipe and completely clean out left over coal, this

will help reduce corrosion. Spray full inside with vegetable oil. If furnace is located in a damp

atmosphere it is recommended to put heat lamp inside furnace to reduce corrosion while furnace is not

running.

• Clean out fly-ash every 1,000 hours or at least once annually. You can expect fly-ash buildup

behind baffle in the base of unit and under pot rings. (remove pot rings once annually to remove fly ash.)

Remove all clean out plates from furnace, (including pot insert clean out on bottom of pot assembly) and

remove fly-ash with ash-vac or by just cleaning out manually. Also remove single wall chimney connec-

tor from furnace and remove fly-ash. There may be some fly-ash buildup in the single wall chimney

connector elbow.

• Check all gaskets and sealer joints for cracks or leaks annually. Replace gaskets or seals as

needed.

Coal

1. Use rice sized coal in your stoker furnace. With not more than 10% oversize and not more than

15% under size. Not following these guide lines will result in poor combustion.

2. Avoid using wet coal, this will retard combustion and increase carbon monoxide output.
