PROBLEM CAUSES SOLUTIONS
? Fire burns with a lazy, orange flame
and/or fuel builds up in the firepot and
excessive (builds up in a hour or so)
soot gets on the window.
Insufficient combustion air.
Feed rate too high.
Corn or wood pellets have too
much moisture – need 14% or less;
10%-12% is ideal.
Combustion/Exhaust blower
plugged or going out
Venting plugged with fly ash or ice.
House does not have adequate
make up air (negative pressure)
 Remove any clinkers or ash from
the firepot by using scraping tool.
Shake ashes into ash pan.
 Clean out primary air in firepot
holes if plugged.
 Empty ash drawer and clean out
back heat exchanger by removing
the lower access plates.
 Tap the side exhaust heat
exchangers to clean them as shown.
 Change to a better grade of fuel if
necessary.
 Check that damper control knob is
adjusted properly. Turn the manual
air knob open until desired burn is
achieved.
 Check gasket seal around the door.
If the door is loose, adjust the
handle latch. A small adjustment
can be made to the door seal by
adjusting the door latch rod and /or
the door hinges. Replace the door
gasket if necessary.
 Check for blockage in the air inlet
tube or exhaust pipe. Clean out as
necessary.
 Check combustion exhaust blower
impeller. This can be done by
removing the exhaust pipe and
shining a light into the tube or
remove inspection cap on exhaust
manifold.
 Replace combustion exhaust blower
if necessary.
NOTE: Negative pressure in a home is
a serious issue. All Magnum furnaces
need to be installed with outside air. If
the home has severe pressure problems
the furnace could become the house air
conduit
causing major operation
problems
