Soot and Flyash - Formation and Need for Removal
The products of combustion will contain small particles of yash. The yash will collect in the exhaust venting system
and restrict the ow of ue gases. Incomplete combustion, such as occurs during startup, shutdown, or incorrect opera-
tion of the room heater will lead to some soot formation which will collect in the exhaust venting system. The exhaust
venting system should be inspected at least once per month (of heavy use) to determine if cleaning is necessary. Corn
has a high ash content.
Daily Maintenance
• Surfaces on the front of the heater will be extremely hot during operation. Always wear heat resistant gloves
to perform periodic maintenance.
• Using a wooden stick, tap the side heat exchangers that are located on the left and right sides of the rebox. When
you open the door, they are located directly inside to the left and right. When you tap the sides with the wooden stick
the loose y ash will drop out of these holes.
• Inspect inside heater for excessive ash build up. You will learn some fuels produce more ash than others. If excessive,
remove the inside ash clean-outs. Once you have cleaned out the ashes, replace the clean-outs. Depending on your
fuel and use, these clean-outs may be removed only weekly.
• If clinkers develops in the repot,clean thoroughly. You may have to do this once or twice a day depending on the
moisture content of the corn. If this is not cleaned out, it could cause the agitator to jam. USSC highly recommends
an additive (see Fuel Additive) be added to your corn to eliminate these clinkers. Contact your local dealer for avail-
ability and cost. You will need this additive if the agitator “ngers” develop an accumulation or build-up.
• The clinkers on the agitator and burnpot are easily removed when soaked in warm water for 10 minutes.
• The ash pan (especially the model 6041I) should be cleaned out on a daily basis or as needed depending ash build-up.
Disposal of Ashes
Ashes should be placed in a metal container with a tight tting lid. The closed container of ashes should be placed on
a noncombustible oor or on the ground, well away from all combustible materials, pending nal disposal. If the ashes
are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all
cinders have been thoroughly cooled.
MAINTENANCE INSTRUCTIONS
DISPOSAL OF ASHES
SPECIAL CLEANING/OPERATIONAL
INSTRUCTIONS:
After cleaning or when operating the
heater, you need to make sure that “both”
clean-outs are in their proper position. If
left out or placed incorrectly, the combus-
tion air is effected greatly and the heater
will not burn properly.
Also, make sure that the ash dumps on
each side of the damper are pushed in
completely. This will also effect the com-
bustion air.
