APPENDIX B: MAINTENANCE GUIDE
Shut off the power to the unit and allow it to cool off when performing cleaning and maintenance.
Regular Cleaning
Removing and cleaning the Firepot The firepot can be removed for cleaning by
loosening the bolt holding the stirring rod in place.
Slide the keeper sleeve off of the gear shaft
exposing the connector piece. Rotate the stirring
rod until the slot is vertical. Now lift the firepot and
the stirring rod out of the firepot holder. To replace
reverse the procedure. The stirring rod can be
manually rotated by holding in the “up” and
“down” arrows on the control board at the same
time. The control board needs to be in the “off”
setting.
Removing “Clinkers” A clinker on the bottom of the firepot, may be
removed with a spoon and dropped into the ash pan.
NOTE: For your Safety, only remove clinkers from
stove when unit is cool.
Wear gloves and eye protection.
Soot and Fly-ash Build Up The ash pan must be emptied every day. If the ash
pan is not emptied regularly ash will build up under
the firepot and block the air flow to the fire pot
putting the fire out. When the stove is cold, the
firepot can be pulled out and removed for a
thorough cleaning. Also, check the drop tube
(where the corn drops into the firepot) for blockage.
Thorough Cleaning Remove the ash pan using a glove. Turn latching
handle and slide the ash pan out of the ash pan
drawer. Dump the ash pan into a fire safe, covered
container. The firepot may be lifted out (first loosen
bolt on the agitator shaft hub and slide hub to the
side) and dump using a glove. With these items
removed, carefully check that the unit and all ashes
are cooled completely. Vacuum out the bottom of
the unit. Vacuum the inside of the unit out
thoroughly and replace all parts, firepot, and ash
pan.
Cleaning the Heat Exchanger. A sliding plate fits over the fifteen tubes of the heat
exchanger. The sliding plate is attached to a small
rod protruding through the front of the stove just
below the louver vent. Push the rod to the back of
the exchanger and then pull forward to the front,
several times. This will effectively remove ash and
debris from the surface of the heat exchanger.
Performing this step often will ensure that cleaning
is an easy task. This cleaning procedure should be
done daily. If buildup is allowed to go unattended,
cleanup will be much more difficult and the
efficiency of your stove will be adversely affected.
CAUTION: Cleaning rod may be hot! Use a
fireplace glove to protect your hand when using the
cleaning rod to avoid getting burned!
