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 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 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 you r serial number from the label on your stove to the box below.

Installation

Installing

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 fromcombustible 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 safetybut do not leave much roomfor 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 thanthe unconnected reading, check for possible restrictions or the need for outside air. (See page 8).

Venting

Requirements for Terminating the Venting

WARNING: Venting terminals must not be recessed 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".1

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 win-

dow/door.1

( with outsideair 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 be a minimum of 12".

F.The clearance to an outside corner is 11" from center of pipe.

G.The clearance to an inside corner is 12".

H.A vent must not be installed within 3 feet (90 cm) above a gas meter/regulator assembly when measured from the horizontal center-line of the regulator.1

I.The clearance to service regulator vent outlet must be a minimum of 6 feet.1

J.The clearance to a non-mechanical air sup-

ply inlet to the building or the combustion air inlet to any other appliance must be a minimum of 48”.1

K.The clearance to a mechanical air supply inlet must be a minimum of 10 feet.1

(with outside air installed, 6 feet )

L.The clearance above a paved sidewalk or a paved driveway located on public property must be a minimum of 7 feet.1,2

M. The clearance under a veranda, porch,deck

or balcony must be a minimum of 12 inches.1,3

NOTE: The clearance to vegetation and other exterior combustibles such as mulch is 36” as measured from the center of the outlet or cap. This 36”

radius continues to grade or a minimum of 7 feet below the outlet.

1Certain Canadian and or Local codes or regulations may require different clearances.

2A vent shall not terminate directly above a sidewalk or paved driveway which is located between two single family dwellings and serves both dwellings.

3Only permitted if veranda, porch, deck, or balcony is fully open on a minimum of 2 sides beneath the floor.

8 PC 45 Corn/Pellet Stove

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 from3" 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.

#1 Preferred method

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 five feet high. This vertical section will provide natural draft in the event of a power failure.

#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.
