The PC 45 Multi-fuel Stove makes burning corn, pellets, or grain 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 ll 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 room sensor, and keep your home at the set temperature.
The PC 45’s automatic temperature control system eliminates the warm/cold cycle associated with thermostatically
controlled heating systems and even turns the PC 45 on and off as needed.
Our exclusive Accordion Heat Exchanger and Air Cooled Combustion Blower allows the PC 45 to produce maximum
heat without creating high exhaust temperatures. The Outside Air option can increase heat efciency even more.
The PC 45 can burn corn or grain with moisture 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.
The label shown here is for reference only. See the unit label
for specic information regarding clearances and testing.

A combustion blower is used to extract the combustion
gases from the rebox. This causes a negative pressure
in the rebox and a positive pressure in the venting
system as shown in g. 7. The longer the vent pipe
and more elbows used in the system, the greater the
ow resistance. Because of these facts we recommend
using as few elbows as possible 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 increased from 3" to 4" because
a larger pipe creates less ow resistance.
Only 3 inch or 4 inch Pellet Vent (PL) Pipe May
be used.
Pellet venting pipe (also known as "PL" vent ) is
constructed of two layers with air space between the
layers. Some manufacturers produce PL vent designed
specically for corn-burning. If planning to burn corn or
other grains, be sure venting system is approved and
warranted for corn-burning. The sections of pipe lock
together to form an air tight seal, however, in some
cases a perfect seal is not achieved. For this reason
and the fact that the PC45 operates with a positive vent
pressure
Outside air is optional except in mobile homes and
where building codes require. The benet of outside
air is mainly noticed in small very tight houses.
To install outside air use 2 3/8" I.D. ex pipe part
number 1-00-08543. There is a break-away hole on the
rear panel which must be removed before connecting
the ex pipe. The pipe should be run outside and
terminate 3 feet or more to the side or below the 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.
When installing in a house with a Heat Reclaiming
Ventilation System (HRV) be sure the system is
balanced and is not creating a negative pressure in
the house.
Fig. 7
= Positive static pressure
= Negative static pressure
8 PC 45 Corn/Pellet Stove
To reduce the probability of back-drafting or burn
back in the appliance during power failure conditions,
the appliance must be able to draft naturally, without
operation of the combustion blower. Negative pressure
in the house may resist this natural draft if not accounted
for during the pellet stove installation.
Heat rises in the house, and leaks out at upper levels.
This air must be replaced with cold air from outdoors,
which ows into lower levels of the house. Vents and
chimneys into basements and lower levels of the house
can become the conduit for air supply, and reverse
under these conditions.
Per national building codes, consideration must
be given to combustion air supply to all combustion
appliances. Failure to supply adequate combustion air
for all appliance demands may lead to backdrafting of
this and other appliances.
When the appliance is side-wall vented;
The air intake is best located on the same exterior
wall as the exhaust vent outlet, and located lower
on the wall than the exhaust vent outlet.
When the appliance is roof vented;
The air intake is best located on the exterior wall
oriented toward the prevailing wind direction,
during the heating season.
The outside air connection will supply all of the
demands of the appliance. However, consideration must
be given to the total house demand. House demand
may consume the air needed for the stove. It may be
necessary to add additional ventillation to the space
in which the appliance is located. Consult with your
local HVAC professional to determine the ventillation
demands for your house.
To reduce the possibility of reverse drafting during a
power failure, Hearth & Home Technologies strongly
recommends:
● Installing the vent pipe with a minimum vertical rise
of ve feet, preferably terminating above the roof line.
● Installing outside air with the intake located below
the exhaust termination.
To prevent soot damage to exterior walls of the house,
and to prevent re-entry of smoke, soot, or ash into the
house:
● Maintain specied clearances to windows, doors,
and other air inlets, including air conditioners.
● Vents should not be placed below ventillated softs.
Whenever possible, run the venting above the roof line.
● Avoid terminating the vent in an alcove location.
● Vents should not terminate under overhangs, decks
or onto covered porches.
● Maintain a minimum clearance of 12" from the vent
termination to the exterior wall. If you see deposits
developing on the wall, you may need to extend this
distance to accomodate your installation conditions.
Hearth & Home Technologies supplies an optional
battery back up system to operate the appliance during
a loss of electrical power. Whether you experience
frequent power failures or not, this back up system is
recommended.

This method provides excellent venting for normal
operation and allows the stove to be installed closest
to the wall. Two inches from the wall is safe; however,
four inches allows better access to remove the rear
panel. The vertical portion of the vent should be three
to ve feet high. This vertical section will help to provide
natural draft in the event of a power failure.
This method also provides excellent venting for normal
operation but requires the stove to be installed farther
from the wall. The vertical portion of the vent should
be three to ve feet high and at least three inches
from a combustible wall. This vertical section will help
to 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.

The grain cap is designed to enhance the burn quality
of the fuel being burned (i.e. eld corn, wheat, barley,
rye, oats, etc.) Its purpose is to reect more heat into
the burn pot. This promotes a more thorough burning
of the fuel and less ash. Depending on the quality of
the fuel being burned, the effectiveness of the grain
cap may vary.
The grain cap will need to be removed for cleaning. This
part is classied as a consumable item and is excluded
from the product warranty.
1. Hook the slot on the grain cap over the lip on the side
rail of the burnpot, as shown.
2. Allow the grain cap to rest onto the burnpot sides.
Grain Cap
Burn Pot
Fig. 18
The PC45 stove is built with a burn pot that has
.125 (1/8") combustion air holes. This grate has no
identifying marks.
Included with your stove is an additional grate that has
.0625 (1/16") combustion air holes. This grate can be
identied with etchings on the bottom side. An ‘S’ is
etched on one end and ‘724208’ is etched at the other
end.
Depending on the type and the moisture content, some
corn or grain will burn better with the smaller holes for
combustion air, while others may work better with the
larger holes.
To change the burn pot grate, rst remove the end gate
retainer, the nthe end gate. Pull the auger extension
from the auger, and lift the grate out of the frame. Place
the new grate, install the auger extension, replace the
end gate and retainer clip. Refer to the diagrams on the
next page for guidance.
The PC45 is built with this burn
pot that has larger holes, Part #1-
10-724108.
Letter “S”
You may opt to change the
burn pot to this version with
smaller holes. This option has
the letter "S" marked on it & is
Part # 1-10-724208.
14 PC 45 Corn/Pellet Stove
For optimal performance burning wood pellets, the pellet kit #1-00-06801 is
now included. This kit allows you to convert the PC45 into a fully automatic
pellet stove with 50,000 BTU capacity, fast ignition and clean viewing glass.
Since there may be changes needed for the circuit board programing, it is
recommended that this installation be completed by a trained service technician.
Be sure the power cord is un-plugged prior to adjusting circuit board switches.
The pellet kit contains the instructions for the conversion, a new burn pot end
gate, and a new combustion blower inlet ring.
This gure shows the corn burn
pot as installed from the factory.
This gure shows the new end
gate which gets installed without
the stirring rod.
This gure shows the pellet burn
pot after installing the new end
gate.
The combustion blower inlet ring on the left is the one originally installed in the stove. Note the larger opening
in the ring on the right. This allows the PC45 to produce more heat when burning pellets. The larger ring does
the opposite when burning corn. If you want to switch back to corn or grain, exchange the inlet ring back to the
smaller opening.

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 re size to be adjusted to match the heating needs and
even put the re out if necessary. If heat is needed after the re is out, the PC 45 will automatically
re-ignite and adjust the re size to match the heating need. The totally automatic room sensor mode
is recommended because of its efciency. The unit can be switched between "AUTO" and "MANUAL"
at any time during operation.
Fig. 19:Room Temperature Mode: 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".
Fig. 20: This setting will produce continuous maximum heat
output with the distribution blower at full speed.
To kill the re or stop burning the stove, turn the Mode Selector
to "OFF". This will cause the re to diminish and burn out. When
the re burns out and the stove cools down everything will s
top.
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 rebox.
If the load door is opened the smoke may escape.
The best way to shut down the stove is to simply let it run out
of fuel, then the stove will shut down automatically.
In "Room Temp Mode" heat output is controlled automatically
by the Room Sensing Probe. When the Room Sensing Probe
calls for heat, the stove will increase output. When the Room
Sensing Probe is getting close to the set temperature, the stove
will begin to level off output and keep the re 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 adjusted
anywhere within the yellow range with a #3 setting being the
maximum setting, #1 the lowest setting. This setting 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 re may be pushed
off the burnpot and extinguish in the ash pan.
In "Room Temp Mode" a constant fuel consumption rate is
sacriced 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 re size.
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.
16 PC 45 Corn/Pellet Stove
Make sure the unit is plugged into a 120 VAC, 60 HZ
electrical source. The power light should be the only
light lit. Anytime there is an interruption in power at the
receptacle, the combustion blower will run for 1 minute
after the power is restored. The control uses this time to
determine exhaust temperature and if there is a need
to remain on.
1.Turn the Mode Selector to "OFF"
2. Fill the hopper with corn or pellets.
3. Clean the burn pot and housing, if necessary.
4. If starting after an empty hopper, turn the feed
adjuster to "TEST" until the fuel is visible in the auger
tube opening. This also allows you to check the motors
for operation.
NOTE: The auger motor will not operate with the view
door or ash door open.
NOTE: The initial start-up on a new stove may require
the corn to be purged into the burnpot area before
continuing to step 5.
5. Turn the feed adjuster to #2 (corn) or #4 (pellet)
6. Flip the igniter switch up into the "AUTO" position.
7. Turn the temperature dial to the desired setting.
8. Turn the mode selector dial to Room Temperature or
Stove Temperature.
9. Fill the hopper with corn or pellets and remove the
ashes as required.

PC 45 Corn/Pellet Stove
The PC45 Corn/Pellet Stove is capable of manual operation. This also allows the operator
to manually control operation during an emergency (i.e. igniter failure, when using some
types of auxiliary power.)
The unit can be switched between "AUTO" and "MANUAL" at any time during operation.
Fig. 22: Room Temperature Mode: This setting will produce a
room temperature of 70 degrees with the distribution blower at
medium speed.
Fig. 23: This setting will produce a large viewing re without a
distribution blower operating.
The re will have to be lit with starting gel and a match,
or started automatically, see "Automatic Operation".
Turn to "Manual" position when the ignition cycle has
started.
The difference between "AUTO" Room Temperature
Mode and "Manual" Room Temperature Mode is that
the re will not go out as the room temperature goes
above the control board setting. The unit can only go to
low burn and will remain there until it runs out of fuel or
until more heat is needed and the feed rate increases.
Feed rate adjustments and dial settings are the same
as "AUTO" settings.
The advantage of this mode is to allow the operator
to have a large viewing re without blowing extra heat
into the room.
During operation, with the temperature dial set at #4
or less, the distribution fan will not operate. Therefore,
there can be a higher burn rate (a larger viewing re)
without an excess of hot air blowing into the room.
An example of when to use the Manual Stove
Temperature Mode is if you want to watch a large re
and the room is already up to temperature. The Stove
Temperature Mode allows you to have a larger re and
a lower sound level, without the distribution blower.

To kill the re or stop burning the stove, turn the Mode
Selector to "OFF". This will cause the re to diminish and
burn out. When the re burns out and the stove cools down
everything will stop.
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 rebox. If the load door is opened the smoke may escape.
The best way to shut down the stove is simply let it run out
of fuel, then the stove will shut down automatically.
Make sure the unit is plugged into a 120 VAC, 60 HZ
electrical source. The power light should be the only light
lit. Anytime there is interruption in power at the receptacle,
the combustion blower will run for 1 minute after the power
is regained.
1. Turn the Feed Adjuster to the desired feed rate,
approximately #2.
2. Turn the Mode Selector to "OFF" and then to the desired
mode. This will reset the control and start the combustion
motor.
3. Turn the Temperature Dial to the desired setting.
4. Clean the burnpot and housing, if necessary.
5. Fill the burnpot with corn up to the auger shaft. Then place
pellets on top of the corn as high as the shelf area. See corn
burnpot shown on left.
6. Add starting gel on top of the pellets, stir gel into the pellets
and corn for faster lighting.
7. Light the starting gel with a match and close the door.
Operation will begin when the fire reaches the proper
temperature.
8. Fill the hopper with corn and remove the ashes as required.
1. Turn the Feed Adjuster to the desired feed rate,
approximately #4.
2. Turn the Mode Selector to "OFF" and then to the desired
mode. This will reset the control and start the combustion
motor.
3. Turn the Temperature Dial to the desired setting.
4. Clean the burnpot and housing, if necessary.
5. Fill the burnpot with pellets so that the auger tube opening
is covered and slopes away from the auger tube opening.
See pellet burnpot shown on left. If using corn burnpot setup,
ll to same level as corn above.
6. Add the starting gel on top of the pellets. Stir the gel into
the pellets for fast lighting.
7. Light the starting gel with a match and close the door.
Operation will begin when the fire reaches the proper
temperature.
8. Fill the hopper with pellets and remove the ashes as
required.

20 PC 45 Corn/Pellet Stove
These units are pre-tested at the factory with exactly
120 Volts A.C., 60 Hz. They are checked and adjusted
for rebox tightness, gasket leakage, 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.
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 efcient 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 to insure
proper set up.
If the unit is not adjusted properly, it does not cause
a safety concern. If the unit is adjusted too high, only
efency 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.
A simple draft test should be performed after
completing the ue pipe installation. To record the
results for future reference:
Combustion Motor Speed Control
Low draft only set point.
The small straight screwdriver slot is plastic; therefore,
the unit can be adjusted while in operation. Fig. 27 Fig. 28
On a PC 45 the draft
hole is under the left
rear corner of the
rebox.
1. Attach a draft meter capable of reading up to a
minimum of 0.5 inches of water column (W.C.).
2. Plug the unit's power cord into a 120VAC, 60 HZ
grounded outlet.
3. Close the hopper lid, front view door, and the ash
pan access door. Neither fuel or a re are required for
this test.
4. With the mode selector in the "OFF" position, turn
the feed adjuster to "TEST".
5. Record the high draft_____in W.C. (Normal is
-.35 to -.55) The control will be on the High Draft for
a minute.
6. After 1 minute is up, the combustion motor will go
down to low draft and the distribution blower will go on
high. Allow approximately 15 seconds to pass for the
combustion motor to slow before checking the low draft.
7. 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.
