13 PC 45 Corn/Pellet Stove
The PC45 corn/pellet stove is more than just automatic ignition, it is also automatic temperature
control. The automatic system will allow the fire size to be adjusted to match the heating needs
and even put the fire out if necessary. If heat is needed after the fire is out, the PC 45 will
automatically re-ignite and adjust the fire size to match the heating need. The totally automatic
room sensor mode is recommended because of its efficiency.
The unit can be switched between "AUTO" and "MANUAL" at any time during operation.
AUTOMATIC IGNITION/OPERATION
Fig. 21: Room Temperature M ode: This setting will produce
a room temperature of 70 degrees with the distribution blower
at medium speed.
This setting will produce medium heat with the
distribution blower on "low".
This setting will produce continuous maximum heat output
with the distribution blower at full speed.
Stove Temperature Mode
Igniter switch to "AUTO"
Room Temperature Mode
In "Room Temp Mode" heat output is controlled auto-
matically by the Room Sensing Probe. When the Room Sens-
ing Probe calls for heat, the stove will increase output. When
the Room Sensing Probe is getting close to the set tempera-
ture, the stove will begin to level off output and keep the fire
burning at just the right temperature to maintain that setting.
High output is determined by the feed rate setting.
This setting, generally on #2 (corn) or #4 (pellet), can be
increased if higher burn rates are necessary.
When burning corn the feed rate setting can be ad-
justed anywhere within the yellow range with a #3 setting
being the maximum setting, #1 the lowest setting. This set-
ting will vary depending on the quality of corn used.
When burning pellets the feed rate setting can be
adjusted within the full range between #1 on the low side to
#6 on the high side.
Overfeeding is not a safety concern, but the fire may
be pushed off the burnpot and extinguish in the ash pan.
In "Room Temp Mode" a constant fuel consumption rate
is sacrificed for exact room temperature. Therefore, as it gets
colder more fuel will be burned automatically.
The distribution blower speed will vary according to the
position of the mode selector pointer, and fire size.
Igniter switch to "AUTO"
Stove Temperature Mode
This allows for automatic ignition upon start-up only.
The unit can then be set at any desired setting. The heat
output and fuel consumption will remain constant regardless
of room temperature.
The unit's low burn or maintenance setting is as low as it
will go. It will not go out unless it runs out of fuel or is turned off.
Shut-Down Procedure
To kill the fire or stop burning the stove, turn the Mode
Selector to "OFF". This will cause the fire to diminish and
burn out. When the fire burns out and the stove cools down
everything will stop . N OTE : T he com bustion blower
motor will run for 5 hours after the stove is completely
cool. This insures that all fuel in the burnpot and ashes
located in the ash pan are completely cold before shut
down of the combustion motor.
If you pull the plug to shut down the stove, all motors will
stop. This may cause incomplete combustion and smoke in
the firebox. If the load door is opened the smoke may es-
cape.
The best way to shut down the stove is simply let it run
out of fuel, then the stove will shut down automatically.
