DAILY MAINTENANCE
 Surfaces on the front of the furnace will be extremely hot during operation. Always wear heat
resistant gloves to perform periodic maintenance.
 Grab the brass knob to move the heat exchanger rod in and out. Do this several times and return it to
operating position, all the way in. This should be performed approximately every 24 hrs.
 Using the clean-out tool, tap the side heat exchangers
that are located on the left and right sides of the
firebox. When you open the door, they are located
directly inside to the left and right. When you tap the
sides with the clean-out tool the loose fly ash will
drop out of the sides to the bottom of the burn area.
This needs to be done once a week.
 While you are tapping the side heat exchangers, we
recommend that you turn the draft lever all the way
open for a minute or two and put the unit on high fire.
This will allow the unit to self-clean the heat exchanger area, the draft fan and exhaust chimney pipe.
 If a clinker ball develops in the firepot, scrape it out with the clean-out. 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 fuel stirrer to jam. Clinker balls are a direct result of excessive corn moisture and they do not
indicate a problem with the stove. AES highly recommends our additive called “Clean Burn” be
added to your corn to eliminate these clinkers. Contact your local Magnum reseller for availability
and cost. Clean burn is not normally needed for the model 6500 furnace.
 Open the stove doors and wipe the inside of the glass
with a damp cloth as needed.
 The ash pan needs to be checked daily to make sure that
the ash has not built up to the bottom of the firepot area.
DISPOSAL OF ASHES: Ashes must be placed in a
metal container with a tight fitting lid. The closed
container can only be placed on a non-combustible
surface well away from any combustible material. If
the ashes are not disposed of by burial in soil or
otherwise dispersed, they need to be retained in the
closed container until all ashes have thoroughly cooled.
 Make sure that the ash pan latches are tightened all of the way
Once ash pan has been replaced.
