Assembly and Installation Unpacking The PC 45 is bolted to the skid to prevent move- ment during shipping. To free the stove from the skid you must re- move the hold-down bolts in the rear of the pedestal base. Installing rear cover panels The rear cover panels are removed from the stove to make it easier to get at the hold-down bolts. The rear cover panels are packed inside the hopper and should be installed on the stove as shown. It is recommended that the rear covers are installed after the unit is in place and the vent pipe is installed.

Venting A combustion blower is used to extract the 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 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 col- lar must be sealed to the stove with high temp...

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 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. 3 ft. Fig. 12 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 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.

Venting #3 Installing into an existing chimney ( US only ) This method provides excellent venting for nor- mal operation. This method also provides natural draft in the event of a power failure. If the chimney condition is questionable you may want to install a liner as in method #6. Fig. 14 #4 Installing into an existing fireplace chimney ( US only ) This method provides excellent venting for nor- mal operation. This method also provides natural draft in the event of a power failure. The damper area must be sealed with a steel plate or fiberglass. A cap should be installed on the chimney to keep out rain. If the chimney condition is questionable you may want to install a liner all the way to the top as in method #5. Fig. 15 PC 45 Corn/Pellet Stove...

Venting #5 Installing into an existing fireplace chimney (US and Canada) This method provides excellent venting for nor- mal operation. This method also provides natural draft in the event of a power failure. In Canada and some places in the US it is required that the vent pipe extend all the way to the top of the chimney. In this method a cap should also be installed on the chimney to keep out rain. Be sure to use approved pellet vent pipe fittings. Seal pipe joints with silicone in addition to the sealing system used by the manufacturer. Pipe size should be increased to 4" using this method. Fig. 16 #6 Installing into an existing chimney ( US and Canada ) This method provides excellent venting for nor- mal operation. This method also provides natural draft in the event of a power failure. In Canada and some places in the US it is re- quired that the vent pipe extend all the way to the top of the chimney. The pipe or liner inside the chimney should be 4"diameter. In this method a cap should also be installed on the chimney to keep out rain. Fig. 17 PC 45 Corn/Pellet Stove...

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 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.
Page 14
AUTOMATIC START UP 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.
Page 15
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-...

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 burning on high continuously will probably 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 combustible materials, 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.
