Burner Lighting
IMPORTANT: Corn or pellets containing stalks,
fines, dirt, etc. may cause the augers to plug,
resulting in excessive wear and possible auger
motor failure. Also, burning treated corn is not
recommended because of increased clinker
buildup and the extinguishing properties of the
treatment used on the corn.
NOTE: If the furnace has ash and clinkers left
over from a previous burn in the burner pot, they
must be completely removed before lighting a
new fire.
NOTE: Use of powdered graphite.
•
During the initial lighting of the furnace, skip
step 1 and only add 2 to 3 cups of corn or
pellets to the storage bin.
•
Then add 1 tablespoon of powdered graphite.
•
Continue with steps 2 through 7 below.
•
As this mixture feeds into the storage bin
auger, repeat this procedure one more time.
•
The powdered graphite will lubricate the
storage bin auger until it begins to polish from
the flow of corn/pellets.
•
This operation should be repeated at the
beginning of each heating season.
•
This operation should also be repeated if the
hopper is allowed to run empty and a sticky
smoke film coats the storage bin auger tube.
•
Powdered graphite may also be added about
once a month at a time when the storage bin
is low on fuel to help the auger stay
lubricated and polished.
NOTE: When lighting the LDJ620-10 furnace
(variable BTU output), always light it with the
furnace set for 100,000 BTU output. After the
furnace has run for thirty minutes, make the
desired adjustments to the output. Refer to
“Variable BTU Timer (LDJ620-10 only)” on
page 17 for more information.
Step 1: Fill the storage bin (1) with dry (15% or
less moisture) and clean (USDA #2 or better)
corn or pellets.
Step 2: Turn on electrical power to the furnace.
Step 3: Turn the thermostat to its highest
setting.
Step 4: Fill the burner pot with corn/pellets (2) to
the lower set of air holes on the inside of the
burner.
