The PC 45 Corn Stove makes burning corn more convenient than ever. It’s special Sidewinder Burn Pot
allows corn to be burned from three days up to a week without cleaning, depending on the corn’s moisture
level and burn rate.
Automatic Ignition allows you to fill the hopper, set your desired room temperature and walk away. The PC
45 will adjust it’s feed rate based on the temperatures received by the roomsensor, and keep your home
at the set temperature.
The PC 45’s automatic temperature control system eliminates the warm/cold cycle associated with ther-
mostatically controlled heating systems and even turns the PC 45 on and off as needed.
Our exclusiveAccordion Heat Exchanger andAir Cooled Combustion Blower allows the PC 45 to produce
maximum heat without creating high exhaust temperatures. The Outside Air option can increase heat
efficiency even more.
The PC 45 can burn corn withmoisture levels up to 16%, with 14.5% or less being ideal. It can also burn
pellets regardless of ash content. This allows you to buy lower cost fuel and still achieve the same results.

Wheninstallingina housewithaHeat Reclaim-
ing Ventilation System(HRV) be sure the system is
balanced and is not creating a negative pressure in
the house.
Outside Air
Outside air is optional except in mobile homes
and where building codes require. The benefit of
outside air is mainly noticed in small very tight
houses.
To install outside air use 2 3/8" I.D. flex pipe
partnumber2-00-08543. Thereis abreak-awayhole
on the rear panel which must be removed before
connectingthe flexpipe.The pipe shouldbe runout-
side and terminate 3 feet or more to the side or be-
lowthe vent pipe outlet. Never terminate the outside
air above the vent pipe outlet. The maximum length
run of this pipe is 15 feet. If a longer run is needed
the size must be increased to 3". Inlet cover part
number 1-10-08542 should be used to keep birds,
rodents etc.out of pipe.
Vent Pipe
Pellet venting pipe ( also known as PL vent ) is
constructed of two layers with air space between
the layers. This air space acts as an insulator and
reduces the outside surface temperature to allow a
clearance to combustibles of only 3 inches. The
sections of pipe lock together to form an air tight
seal in most cases; however, in some cases a per-
fect seal is not achieved. For this reason and the
factthatthe PC45operates witha positiveventpres-
sure we specify that the joints also be sealed
with clear silicone.
Venting
Fig. 11
Acombustionbloweris usedto extractthe com-
bustiongases fromthefirebox.This causes a nega-
tive pressure in the firebox anda positive pressure
inthe ventingsystemas shown infig. 10. The longer
the vent pipe and more elbows used in the system,
the greater the flow resistance. Because of these
facts we recommend using as few elbows as pos-
sible and 15 feet or less of vent pipe. The maximum
horizontal run should not exceed 48". If more than
15 feet of pipe is needed, the diameter should be
increasedfrom3" to4" becausea largerpipe causes
less flow resistance. Be sure to use approved
pellet vent pipe wall and ceiling pass through
fittings to go through combustible walls and
ceilings. Be sure to use a starting collar to attach
the venting system to the stove. The starting col-
lar must be sealed to the stove with high temp
silicone caulking.

#1 Preferred method
This methodprovides excellent ventingfor nor-
mal operation and allows the stove to be installed
closest to the wall. Two inches from the wall is safe;
however, fourinches allowsbetter accesstoremove
the rearpanel.Theverticalportionof thevent should
be three to five feet high. This vertical section will
provide natural draft in the event of a power failure.
#2 Preferred method
This methodalso provides excellent ventingfor
normaloperationbutrequires thestove tobe installed
farther from the wall. The verticalportion of the vent
should be three to five feet high and at least three
inches from a combustible wall. This vertical sec-
tion will provide natural draft in the event of a power
failure.
If the stove is installed below grade the vent
termination should be at least 1 foot above grade.
CAUTION
Keepcombustible materials(such as grass, leaves,
etc.) at least 3 feet awayfrom the flue outlet on the
outside of the building.

13PC45Corn/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

a room temperatureof70 degrees withthe distribution blower
at medium speed.
This settingwill produce medium heatwith the
distribution bloweron "low".
This settingwill produce continuous maximum heatoutput
with the distributionbloweratfull speed.
Stove Temperature Mode
Igniter switch to "AUTO"
Room Temperature Mode
In "Room Temp Mode" heat output is controlled auto-
matically by theRoomSensing Probe.WhentheRoomSens-
ing Probe calls for heat, the stove willincrease 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"RoomTempMode"aconstantfuelconsumptionrate
issacrificed for exactroom temperature.Therefore,as it gets
colder more fuel will be burned automatically.
The distribution blower speed will vary according to the
positionof 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 willstop. NOTE: The combustion blower
motor will run for 5hours 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 ofthe combustion motor.
If you pull the plug to shut downthe 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 downthe stove is simply let it run
out of fuel, then the stove will shut down automatically.

15PC45Corn/Pellet Stove
The PC45 Corn/Pellet Stove is capable of manual operation. This also allows the op-
erator to manually control operation during an emergency (i.e. ignitor failure, when using a
502H battery backup, or when using certain generators.)
The unit can be switched between"AUTO" and "MANUAL"atany time duringoperation.
NOTE:When startingthe unitin the"AUTO" mode andswitchingto"MANUAL",
the fire must be large enough to turn the ignitor light off (located on the control
board). This is a signal that the start cycle is completed and the fire will not go out.

Igniter Switch to "MANUAL"
Room Temperature Mode
The fire will have to be lit with starting gel and a
match, or started automatically, see "Automatic Op-
eration". Turn to "Manual" position when the fire is es-
tablished.
The difference between "AUTO" Room Tempera-
ture Mode and "Manual" Room Temperature Mode is
that the fire will not go out as the room temperature
goes above the controlboardsetting.The unitcanonly
go to low burn and will remain there until it runs out of
fuel or until more heat is needed and the feed rate in-
creases. Feed rate adjustments and dial settings are
the same as "AUTO" settings.
Igniter Switch to "MANUAL"
Stove Temperature Mode
The advantage of this mode is to allowthe opera-
tor to have a large viewing fire without blowing extra
heat into the room.
During operation, with the temperature dial set at
#5 or less, the distribution fan will not operate. A #5 on
the temperature dial and a #5 on the feed adjuster is
approximately 80% output. It is not necessary to oper-
ate the distribution blower below this point. Therefore,
there can be a higher feed rate ( a larger viewing fire)
without an excess of hot air blowing into the room.
Anexampleof whento usethe ManualStove Tem-
perature Mode is if you want to watch a large fire and
the room is already up to temperature.The Stove Tem-
perature Mode allows you to have a larger fire and a
lower sound level, without the distribution blower.
NOTE: During the use of this mode, if you
keep increasing the temperaturedial settingto in-
creasethe firesize, the distribution blowerwill au-
tomatically come on when the ESP Temperature
reaches 350oF, or 81%output.

These units are pre-tested atthe factorywith
exactly 120 VoltsA.C.,60 Hz. They are checkedand
adjusted for fireboxtightness, gasketleakage, motor
operation and ignitor operation. The PC 45 is then
factory set at a mid-point adjustment and in most
cases will not need any adjustments. NOTE: The
factory low draft setting may not be correct for
theunitspermanentinstallation conditions.
The control board on the PC45 is equipped
with a low draft adjustment port. Located on the
control face just to the right of the igniter light. This
voltage adjustment is provided to allow the unit to be
adjusted for the household voltage where the unit is
going to be in permanent operation. NOTE: The line
voltage varies from area to area and often home to
home. The low draft voltage should be adjusted to
achieve the most efficient burn on low burn or
"maintenance". This voltage adjustment allows the
installer to change the low voltage set point
approximately 10 volts. This adjustment should be
done by the installer during set up because a draft
meter reading is required to insure proper set up.
If the unit is not adjustedproperly, itdoes not
cause a safety concern. If the unit is adjusted too
high, only effiency is lost. If the unit is adjusted too
low, the low draft pressure switch will not allow the
feeder motor or the igniter to operate.

Asimple drafttestshouldbe performedafter
completing the flue pipe installation. To record the
results for future reference:
1. Plug unit into a 120VAC, 60 HZ outlet.
2. Close the hopper lid,front viewdoor, andthe ash
pan access door. Neither fuel or a fire are required
for this test.
3. With the mode selector in the "OFF" position,
turn the feed adjuster to "TEST".
4. Record the high draft_____in W.C. (Normal is
-.35 to -.55) The control willbe on the HighDraft for
a total of 2 minutes.
5. After 2 minutes is up, the combustion motor will
go down to low draft and the distribution blower will
go on high.Allowapproximately 15 seconds to pass
for the combustion motor to slow before checking
the low draft.
6. If the low draft is between -.25 and -.35, record
the reading _____ in W.C. If the reading is higher,
slowly turn the set screw counter-clockwise until the
draft lowers. If the reading is lower, very slowly turn
the set screw clockwise until the draft increases.
NOTE: The test mode alternates from high to
low draft every 60 seconds. If more time is
needed for draft adjustment,wait until the next
low draft cycle.
NOTE: In some cases, the draft may not go as
low as -.25 to -.35 even with the set screw
completely counter-clockwise. This is not a
problem.

Removing Ashes:
The frequency in which you will need to empty
the ash pan will vary depending on the conditions
that the stovehas beenoperatingin.For example:A
stove burningon highcontinuouslywillprobably need
the ashes removed every 1 to 2 days, whereas a
stove burning on low or cycling off periodically may
be able to go 3 to 8 days or longer.
Ashes should be placed in a metal con-
tainer with a tight fitting lid. The closed con-
tainerof ashes should beplaced on a noncom-
bustible flooror on the ground, well awayfrom
all combustiblematerials,pendingfinal disposal.
If ashes are disposed ofbyburial in soil or oth-
erwise locally dispersed, they should be re-
tained in the closed container until all cinders
have thoroughlycooled.
It is recommended that the stove is cold and
shut down when removing ash pan.
1. Pull up on the latch handle to swing the ash pan
access door out and to the right.
2. Use the ash pan handle to carry and dispose of
ashes.
3. Slide the ash pan back into the stove.
Cleaning:
If you have been burning corn, the stove will
need to be cleaned approximately once a month.
The amount of corn burned and the frequency of
these cleanings will varydepending on the quality of
the corn used.
If you have been burning pellets, the stove will
need to be cleaned approximately every 2 to 3
months. The amount of pellets burned and the fre-
quency of these cleanings will vary depending on
the quality of the pellets used.
1. Shut down stove and disconnect power cord
to insure that all motors are stopped.
2. Clean the heat exchanger with the scraper as
shown if Fig. 32.
3. Brush or scrape the inside walls of the stove to
remove fly ash.
4. Remove the burn pot for cleaning by:
•Liftupandremove thefront platelock&frontplate.
•Remove the auger extension (cornburnpot only).
•Remove the burnpot grate.
•Clean all fines and debris.
•Reinstall in reverse order.

8. Use a brush to clean the flue, beingcareful not to
damage the ESP probe. The flue goes straight
through into the vent pipe therefore, the vent pipe
can also be cleaned to some extent through the flue
outlet.
9. Reinstall the blower cover and relatch.
10. Slide ash paninto the stove andlatchinto place.
Cleaning of Feeder Fines Area
1. Remove the rear shields to access the feeder
cover.

Soot and Fly Ash
The products of combustion will contain small
particles of fly ash. The fly ash will collect in the
exhaust venting system and restrict the flow of the
flue gases. Incomplete combustion, such as oc-
curs during startup, shutdown, or incorrect opera-
tion of the room heater, will lead to some soot for-
mation which will collect in the exhaust venting sys-
tem. The exhaust venting system should be in-
spectedafter the first monthof burningto determine
thefrequencyofcleaningthatwillberequired.NOTE:
The frequencycouldvaryfromonceamonthto once
a season depending on the quality of the fuel being
used.
