2 PC 45 Corn/Pellet Stove
Introduction
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 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 ther-
mostatically 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
efficiency even more.
The PC 45 can burn corn 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.
Please copy your
serial number from the
label on your stove to

Installing
Installation
Place the stove on a noncombustible floor protector that extends 6 inches to the front, 6 inches to the
sides and 1 inch to the rear of the stove. The minimum
floor protector material is 24 gauge sheet metal.
Place the stove away from combustible walls at least
as far as shown in figures 6,7 & 8. Please note the difference in side wall clearance with and without side shields.
Note that the clearances shown are minimum for
safety but do not leave much room for access when cleaning or servicing. Please take this into account when placing the stove.
Connect the power cord to a 120 V.A.C. 60Hz
grounded receptacle. (A surge protector is recommened
to protect the circuit board).
Prior to installing the flue pipe, connect a draft meter
to the stove as shown in fig. 9. (The draft meter must
have a minimum range of 0"- 0.5"). Turn stove to "TEST"
Mode and record the draft reading ______. After the flue
pipe is connected, check the draft reading again making
sure all doors and windows in the home are closed. If
this reading is more than.05" higher than the unconnected
reading, check for possible restrictions or the need for
outside air. (See page 8).

Requirements for Terminating the Venting
WARNING: Venting terminals must not be re-
cessed into a wall or siding.
NOTE: Only PL vent pipe wall pass-throughs
and fire stops should be used when venting through
combustible materials.
NOTE: Always take into consideration the effect the prevailing wind direction or other wind currents will cause with flyash and /or smoke when placing the termination.
In addition, the following must be observed:
A. The clearance above grade must be a minimum of 18".
B. The clearance to a window or door that may
be opened must be a minimum of 48" to the side,
48" below the window/door, and 12" above the window/door.
( with outside air installed, 18” )
C. A 12" clearance to a permanently closed
window is recommended to prevent condensation
on the window.
D. The vertical clearance to a ventilated soffit
located above the terminal within a horizontal distance of 2 feet (60 cm) from the center-line of the
terminal must be a minimum of 18".
E. The clearance to an unventilated soffit must

IMPORTANT NOTICE
Pellet Vent Pipe or PL Vent Pipe Must be used.
+ = Positive static pressure
Fig. 10
= Negative static pressure
A combustion blower is used to extract the combustion gases from the firebox. This causes a negative pressure in the firebox and a positive pressure
in the venting system as shown in fig. 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 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 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 collar must be sealed to the stove with high temp
silicone caulking.
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 perfect seal is not achieved. For this reason and the
fact that the PC45 operates with a positive vent pressure we specify that the joints also be sealed
with clear silicone.

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
part number 2-00-08543. There is a break-away hole
on the rear panel which must be removed before
connecting the flex 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.
HRV
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.
Venting
mal 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 five feet high. This vertical section will
provide natural draft in the event of a power failure.
#1 Preferred method
This method provides excellent venting for nor-

to
combustibles
#2 Preferred method
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 five feet high and at least three
inches from a combustible wall. This vertical section 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
Keep combustible materials (such as grass, leaves,
etc.) at least 3 feet away from the flue outlet on the
outside of the building.
