PROBLEM
CAUSES
SOLUTIONS
Fuel burns off to quickly, have difficulty
keeping a pilot fire.
Air shutter is open to far.
Over drafting on a vertical install.
Outside air is not hooked up
Positive or negative pressure in home is
affecting the furnace operation
The cold air return is not hooked up or is
drawing from inside the furnace room
Adjust your air shutter to a more closed
position.
A chimney restrictor may need to be
installed. Consult with your Magnum 7500
dealer.
Make sure that the installation is correct
and nothing is affecting the furnace room
Foreign object caught in the auger and
will not turn.
Accidental object in fuel.
If there still is a fire, let it extinguish and
let furnace cool down. Unplug furnace
after furnace has exhausted. It will be
necessary to clean out hopper. As you are
facing the furnace open the right hand side
panel. The auger motor will have a small
cooling fan on the back. Turn the fan
counter clockwise until tension is off the
auger. Open the front door of the furnace
and pull the auger out. Prying on the auger
without loosening first can damage auger
gear box.
Getting to much ash.
Dirty fuel
Wet fuel
Lack of clean combustion air.
Dirty or plugged stove or venting. Poor
exhaust vent configuration.
Negative pressure present in the home
Combustion motor going out.
Use combustion enhancement system
Adequately screen corn. Dirty , wet fuel
will produce excessive ash
Take proper steps to check corn for proper
moisture and to adequately protect from
the elements to not take on moisture.
Check damper control and check
combustion air inlet for obstructions.
Check all cleanouts and exhaust venting
for obstructions. Refer to cleaning section
of this manual.
Call your Magnum 7500 reseller to inspect
installation and operation. Replace any
bad parts.
On higher heat settings combustion
enhancement system will keep ash
volume down.
The heat output is not as high as when
the furnace was installed.
Wet or dirty fuel.
Inadequate cleaning.
Dirty room air filter.
Change of fuel to lower BTU value
Negative pressure or improper ductwork
is causing unit to perform improperly
Wet fuel has a much lower BTU output.
The furnace requires 14% or lower
moisture corn. Dirty fuel does not produce
adequate heat. Excessive amounts of fines
interrupt the amount of corn delivered for
burning and will decrease heat output.
Clean heat exchangers daily, tap side
exchangers, inspect furnace for air flow.
Clean or replace filter.
Have dealer check for proper installation
and negative pressure in home.
IMPORTANT: Electrical work must be performed by an authorized technician.
