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 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 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

Venting  
IMPORTANT NOTICE  
Acombustion blower is usedto extractthe com-  
bustion gases from the firebox. This causes a nega-  
tive 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 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 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 col-  
lar must be sealed to the stove with high temp  
silicone caulking.  
PelletVent Pipe or PLVent Pipe Must beused.  
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  
fact thatthe PC45 operates witha positive ventpres-  
sure we specify that the joints also be sealed  
with clear silicone.  
+ = Positive static pressure

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  
partnumber 2-00-08543. There is abreak-awayhole  
on the rear panel which must be removed before  
connecting the flex pipe. The pipe should be run out-  
side and terminate 3 feet or more to the side or be-  
low 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.

Venting  
#1 Preferred method  
This method provides excellent venting for nor-  
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 portionof the vent should  
be three to five feet high. This vertical section will  
provide natural draft in the event of a power failure.  
3 ft.

#2 Preferred method  
This method also provides excellent venting for  
normaloperation butrequires the stove tobe 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 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  
Keep combustible materials (such as grass, leaves,  
etc.) at least 3 feet away from the flue outlet on the  
outside of the building.

AUTOMATIC IGNITION/OPERATION  
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.  
Igniter switch to "AUTO"  
Room Temperature Mode  
In "Room Temp Mode" heat output is controlled auto-  
matically by theRoom Sensing Probe. Whenthe 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  
Fig. 21:Room Temperature Mode: This settingwill produce  
a room temperature of70 degrees with the distribution blower  
at medium speed.  
#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 fuelconsumptionrate  
is sacrificed for exact room temperature. Therefore, as it gets  
colder more fuel will be burned automatically.  
Stove Temperature Mode  
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.  
This setting will produce medium heatwith the  
distribution bloweron "low".  
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. NOTE: The 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.  
This setting will produce continuous maximum heatoutput  
with the distributionblower at full speed.

Starting the Fire  
Igniter Switch to"AUTO"(up position)  
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 Mode Selector to "OFF"  
Fig. 23  
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-upona newstove mayrequire  
the corn to be purged into the burnpot area before  
continuing to step 5.

MANUAL IGNITION/OPERATION  
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" at any time during operation.  
NOTE: When starting the unit in the "AUTO" mode and switching to "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 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 in-  
creases. Feed rate adjustments and dial settings are  
Fig.24: Room Temperature Mode: This settingwill produce a  
room temperature of 70 degrees with the distribution blower  
at medium speed.  
the same as "AUTO" settings.  
Igniter Switch to "MANUAL"  
Stove Temperature Mode  
Manual Stove Temperature Mode  
The advantage of this mode is to allow the 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.  
An example of whento use the 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 temperature dial setting to in-  
crease the fire size, the distribution blower will au-  
tomatically come on when the ESP Temperature  
reaches 350o F, or 81%output.

Shut-Down Procedure  
Fig. 28  
To kill the fire or stop burning the stove, turn the Mode  
Selector to "OFF". This will cause the fire to diminishandburn  
out. When the fire burns out and the stove cools down every-  
thing will stop. NOTE: The combustion blower motor will  
run for 5 hours after the stove is completely cool. This in-  
sures 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, allmotors will  
stop. This may cause incomplete combustionandsmokeinthe  
firebox. If the loaddooris openedthe smokemay escape.

Low Draft Voltage Adjustment  
These units are pre-tested at the factory with  
A simple draft test should be performed after  
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, and the 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 will be on the High Draft 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.  
exactly 120 Volts A.C., 60 Hz. They are checked and  
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  
theunits permanent installation 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 adjusted properly, it does 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.  
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.

Maintenance  
Removing Ashes:  
The frequency in which you will need to empty  
the ash pan will vary depending on the conditions  
that the stove has been operating in. For example:A  
stove burningon highcontinuously willprobably 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-  
tainer of ashes should be placed on a noncom-  
bustible floor or on the ground, well away from  
all combustiblematerials, pending final disposal.  
If ashes are disposed of by burial in soil or oth-  
erwise locally dispersed, they should be re-  
tained in the closed container until all cinders  
have thoroughly cooled.  
It is recommended that the stove is cold and  
shut down when removing ash pan.  
Fig 31Corn Burnpot  
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:  
HeatExchanger Fins  
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 vary depending 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.

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-  
spected after the first month of burning to determine  
the frequencyof cleaning thatwill be required. NOTE:  
The frequencycould varyfrom once a monthto once  
a season depending on the quality of the fuel being  
used.

Maintenance - Burn Pot  
Burn Pot Cleaning and Maintenance  
1. Be sure the stove power is turned off.  
2. Lift up and remove the front plate lock and front  
plate. Set aside the front plate.  
3. Remove the auger extension by pulling toward  
you, then set aside (corn burnpot only)  
4. Remove burnpot grate and set aside.  
5. Clean all fines and debris that has accumulated.  
6. Install the spare "clean" burnpot grate making sure  
the 2 holes line up with the 2 tabs in the burnpot  
housing.  
7. Now install the spare "clean" auger extension into  
the auger shaft. Make sure there isn't any corn or  
debris inthe shaftopening. This willpreventthe auger  
extension from being fully inserted into the shaft.  
8. Align the auger extension through the hole in the  
spare "clean" frontplate andplace frontplate against  
the burnpot grate and housing.  
Fig. 40:Corn Burnpot  
9. Install the front plate lock.  
10. The "dirty" auger extension, burnpot grate and  
front plate just removed can now be cleaned for the  
next scheduled maintenance. NOTE: After cleaning  
of these parts, inspect for excessive wear and  
replace as needed.  
Cleaning of Burnpot Parts  
Cleaning can be performed in 2 basic ways:  
1. Because the slag buildup will absorb moisture  
from the air when cool, the parts can just be left  
exposed for several days and the slag buildup will  
crumble off of the parts.  
2. To accelerate this process, the parts can be  
soaked in water for approximately 30 minutes  
(depending on the amount of buildup, they could be  
cleaned in less time).  
NOTE:Cleaning of these parts is notnecessary until  
you see that there is noticeable decrease in the  
quality of the flame in the burnpot. Example:  
Unburned fuel being pushed over the burnpot.

PC 45 Trouble-Shooting  
FEEDER DOES NOT FEED  
SMOKE IS VISIBLE COMING OUT OF VENT  
1. No fuel in hopper.  
1. Air-fuel ratio is too rich.  
2. Firebox draft may be too low for low draft pres-  
sure switch in feeder circuit to operate. Check for  
closed doors, loose or missing gasket on doors  
or hopper lid, faulty pressure switch.  
3. Feed motor will not run until ESP senses 200o F.  
Maybe you did not put enough pellets in the burn  
pot before lighting the fire.  
4. Something is restricting flow in the hopper or  
causing the slide plate to stick.  
5. Feed motor has failed.  
A. Feed rate too high.  
B. Draft too low caused by a gasket leak.  
2. Unit is in an ignition cycle.  
LOW HEAT OUTPUT  
1. Feed rate too low  
2. Temperature setting too low(Stove Temp Mode)  
3. Draft too low because of gasket leak.  
4. Poor quality or high moisture fuel.  
Helpful Hints  
PARTIALLY BURNED FUEL  
1. Feed rate too high.  
2. Draft too low.  
3. Burn pot may need to be cleaned.  
4. Combination of all the above.  
5. #6 status blink: A 6 blink control board status  
indication is caused by poor or incomplete com-  
bustion. The circuit board has the ability to track  
the combustionthrough feedsettings andESP tem-  
peratures. When the control board has calculated  
poor or incomplete combustion it will shut down  
the unit as a safety feature. (Poor or incomplete  
combustion is a contributer of creasote which may  
cause a chimney fire)  
Cleaning Burn Pot  
Whenever your stove is not burning, take the  
opportunity to scrape the burn pot to remove car-  
bon buildup. A vacuum cleaner is handy to remove  
the residue. Be sure the stove is cold if you use a  
vacuum.  
Carbon buildup can be scraped loose with the  
fire burning using the special tool provided with your  
stove. Scrape the sides of the burnpot (corn grate),  
and the floor and sides (pellet grate). The carbon  
will be pushed out by the incoming fuel. Always wear  
gloves to do this.  
A 6 blink status may be caused by several things:  
1. Blocked or partially blocked flue.  
2. Blocked or partially blocked inlet air.  
a. backdraft damper on the inlet pipe may be  
stuck closed.  
b. if outside air is installed the inlet cover may be  
blocked.  
3. The air chamber under the burnpot may be filled  
with fines and small bits of ash.  
4. The holes in the burnpot may be getting filled  
with ash or carbon buildup.  
5. Combustion blower fan blades may need  
cleaned.  
6. There is no fuel in the hopper.  
Removing Ashes  
Turn the Temp Dial to number 1 approximately  
30 minutes before removing ashes. This will result  
in a cooler stove and ash pan.  
Maximum Feed Adjuster settings are not  
needed in most cases. Operating in the normal  
range (#2 corn) (#4 pellet) is recommended when  
maximum heat output is not required. The ESP  
probe prevents the stove from being over-fired.  
Keep the stove free of dust and dirt.  
Fuel  
The PC 45 can burn corn with moisture levels  
up to 16%, with 14.5% or less ideal.  
COMBUSTION BLOWER RUNSAFTER SHUT DOWN  
This is a normal function. The combustion blower  
will run for 5 hours after the stove is completely  
cool.  
Pellet fuels are put into 3 categories in terms of  
ash content. Premium at 1% or less, Standard at  
3% or less and all others at 3% or more.  
The PC 45 is capable of burning all 3 catego-  
ries of pellets due to a patented feeder and burn pot  
system.  
SMOKE SMELL  
Seal the vent pipe joints and connection to stove  
with silicone.  
Itshouldbe noted, however, thathigher ashcon-  
tent will require more frequent ash removal and may  
provide less BTU's per pound. Normally, standard  
and high ash pellets cost less than premium pellets  
and can be cost effective when burned in the PC 45.  
The moisture content of pellets must not exceed  
8%. Higher moisture will rob BTU's and may not burn  
properly.  
FIRE HAS GONE OUT  
1. No fuel in hopper.  
2. Draft setting is too low.  
3. Something is restricting fuel flow.  
4. Feed motor or draft motor has failed.  
5. Power failure or blown fuse.

"Sunrise" Gold Trim  
Gold Door  
This kit includes a gold trim piece for the ash lip  
and a gold Sunrise piece for the door. See Fig. 42.  
Referring to the diagram, page 5, note how the  
various components of the door system fit together.  
Lay the load door face down on a soft surface.  
Clean the glass thoroughly using a nonabra-  
sive glass cleaner. Install the glass gasket around  
the outer edge of the front face of the door glass  
carefully to insure proper sealing.  
The gold door (fig. 43) is assembled and in-  
stalled the same as the standarddoor. Refer to page  
5. Be careful not to scratch the glass and be sure to  
clean the gold before starting a fire in the stove.  
To install ash lip trim, simply slide the trim over  
the ash lip and into the groove on the trim.  
Cleaning Gold  
Note: There are 4 tabs on the Sunrise. These  
tabs have a step on the front side and are flush on  
the back side. Place the "Sunrise" in the door so the  
step side is to the front.  
Set the glass pane gently onto the door. In-  
stall the hold-down clips and tighten with bolts as  
shown on page 5.  
The gold plated door and gold Sunrise should  
never be buffed or polished. Abrasivecleansers and  
metal polishes will remove the plating and therefore  
should never be used. If the gold needs to be  
cleaned, wait until the stove is completely cool, then  
use a sponge, soap and water to gently remove dirt  
and stains. Before relighting the stove, remove all  
soap residue and wipe dry.  
To install ash lip trim, simply slide the trim over  
the ash lip and into the groove on the trim.

Room Sensor Installation  
Hopper Extension  
The hopper extension allows you to put more  
pellet fuel in the hopper and extends burn time on one  
load of corn. The hopper extension adds 65 pounds to  
the existing 80 pound hopper capacity, allowing you to  
load 145 pounds of corn at one time. See Fig. 46.  
Fig. 44  
The room sensor is a small temperature sensor  
on the end of a 60" gray wire. This sensor is installed  
much like a standard wall thermostat. Because it is so  
small, it can be hidden along the trim of a doorway or  
even up the leg of a coffee table. There is a remote  
room sensor port on the rear of the unit for easy exter-  
nal connection. Use standard 18-2 thermostat wire to  
extend the distance to the desired location (100' maxi-  
mum). The room sensor should be installed in the loca-  
tion where you want to control the temperature.  
NOTE: Distances of more than 25 feet from the  
unit or in another room are not recommended.The room  
sensor isessentialfortheAccentra's excellent efficiency.  
It is recommended that the room sensor be  
installed, evenif only installed onthe rear of the unit as  
a return air sensor. There is an intake screen on the  
bottom ofthe rear sheetmetal enclosure. This is an ideal  
place to tyrap the sensor head to sense return air tem-  
perature.  
Fig. 46  
Optional Pellet Burnpot Grate  
The pellet burnpot grate is required to burn  
pellet fuel.  
The cornburnpot andpellet burnpotgrates were  
designed to be interchangeable, and are easily installed  
and removed without the use of tools.  
Each PC 45 comes with (2) corn burnpot grates  
to aid in continual burning of corn in the event that the  
corn burnpot needs to be cleaned. Please note they  
are both corn burnpot grates, notone corn grate and  
one pellet grate.  
Side Heat Shields  
Side heat shields are available to reduce the  
clearance to combustible materials. See Fig. 45.  
Fig. 47: Optional PelletBurnpot Grate  
Optional Hopper Screen (Corn Strainer)  
The hopper screen/corn strainer was designed  
to sift the corn before it is fed into the burn pot. This  
sifting will catch unwanted materials from being burned.
