Planning Your Installation
Questions To Ask Local Building Official
A correct installation is critical and imperative for reducing fire hazards and perilous conditions that can arise when wood pellet burning appliances are improperly installed. The installer must follow all of the manufactur- ers??? instructions.
WARNING
Check all local building and safety codes before installation. The installation instructions and appro- priate code requirements must be followed exactly andwithoutcompromise.Alterationstothestoveare not allowed. Do not connect the stove to a chimney system serving another stove, appliance, or any air distribution duct. Failure to follow these instructions will void the manufacturers warranty.
The installation of this appliance must conform to local codes and appli- cable state and federal requirements. Familiarity with these requirements before installation is essential. Important considerations to discuss with local building officials include:
1.Applicable codes (i.e. Uniform Mechanical Code, State or Regional Codes).
Electrical codes:
In USA, NEC, ANSI/NFPA 70 ??? Latest Edition In Canada, CSA C22.1 ??? Latest Edition
Power Supply Requirements
The power cord must be plugged into a standard, 120 volt, 60 Hz grounded electrical outlet. The power supply cord must be routed to avoid contact with any of the hot or sharp exterior surface areas of the stove. When installed in a manufactured home, the appliance must be electrically grounded to the steel chassis (see Mobile Home Installations on Page 11, for additional requirements). These requirements must be met unless otherwise specified by state or local authorities.

5.Rooms where the installation is not allowed
Surge Protectors - A surge protector is recommended to ensure the stove???s electrical components are not damaged due to a surge in the electrical supply. Only high quality protectors should be used - cheap ones do not provide the protection needed.
Smoke Detectors - Since there are always several potential sources of fire in any home, we recommend installing smoke detectors. If possible, install the smoke detector in a hallway adjacent to the room (to reduce the possibility of occasional false activation from the heat produced by these appliances). If your local code requires a smoke detector be installed within the same room, you must follow the requirements of your local code. Check with your local building department for require- ments in your area.
Installation / Maintenance Standards - National Fire Protection Associa- tion ??? The primary NFPA standard that refers to installation and main- tenance of pellet appliances and venting is NFPA 211 ??? Latest Edition: Chimneys, Fireplaces, Vents, and Solid Fuel appliances.
SELECTING A LOCATION
The design of your home and where you place your stove will determine its value as a source of heat. This type of appliance depends primarily on air circulation (convection) to disperse its heat, and therefore, a central location is often best. There are other practical considerations, which must be considered before a final selection of locations is made.
???Existing Chimneys
???Pellet Fuel Storage
???Aesthetic Considerations
???Roof Design (rafter locations & roof pitch)
???Room Traffic
???Proximity to Combustibles
???Electrical Wiring
CAUTION
The body of these appliances are very heavy. The use of a heavy duty escalara (stair step hand truck) is recommended for lifting the appliance body.
NEGATIVE PRESSURE WARNING
This appliance is not designed to be operated in a negative pressure. Very airtight homes with large kitchen exhaust fans, or homes with furnace cold air returns located in close proximity to the stove may create nega- tive pressure in the same room as the heating appliance. This can create dangerous condition, drawing combustion

Installation
Control Board Installation
The Winslow PI40 insert is shipped with the control board wrapped and placed behind the firebox. To install the control board, unwrap it and the right side surround panel found in the surround kit. There are four prongs protruding from the surround. Place the two slots in the bottom and the two holes in the top of the control board over the four prongs on the surround panel. Install the surround panels following the instruc- tions on Page 10.
Venting
Pellet pipe type PL, L, or listed pellet flex liner must be used to vent the Winslow??? PI40 insert. The insert???s flue collar is 3??? in diameter. The insert???s combustion blower pressurizes and pushes flue gases out the pellet pipe. All pipe joints should be locked together or screwed with three screws if the pipe does not have a locking system. The pipe joints can be sealed with high temperature silicone if there is a possibility of flue gases leaking into the living area. The pipe should be fastened with three screws to the insert???s flue collar. The longer the run of pipe and the more elbows used, the greater the resistance to the flow of flue gases. Four inch diameter pellet pipe is recommended for pipe runs greater than 15 feet or when a number of elbows are used. A

Filling the Hopper
The hopper can be accessed by lifting the lid at the rear of the top of the insert. The hopper will hold 60 pounds of pellets. Remove any contents from the hopper and fill with pellets.
Lighting
1.Turn the heat selector knob (see Figure 34) to the heat level desired - 1 through high - and the ready light will turn green.
2.Push the start button and the ignite and feeding lights will come on and the lighting sequence will begin. For about the next 15 minutes the insert will feed pellets cyclically into the burn pot, the combustion fan will come on, and the igniter will heat up. During this sequence, some smoke in the firebox is to be expected. After the igniting sequence is complete, the insert will begin burning at the level indicated by the heat selector knob.
Note: Upon the insert???s initial light up, or if the insert has previously run out of pellets, the auger feed tube may not contain a sufficient number of pellets to allow the insert to continue burning after the ignition sequence. It may be necessary to push the start button a second time to run the start sequence again. It is important to always empty (when cool) the burn pot of pellets before pushing the start button a second time.
WARNINGS
???Never empty pellets from the
???DO NOT OVERFIRE THIS STOVE. This may cause serious damage to your stove and void your warranty. It also may create a fire hazard in your home. IF ANY
EXTERNAL PART OF THE UNIT BEGINS TO GLOW, YOU ARE OVERFIRING. Immediately slide the knob to the "OFF" position on the control board.
Manual Operation
After the insert is burning (see Lighting on this page), the heat selector knob controls the pellet burn rate and the insert???s heat output. Turning the knob to setting 1 allows the insert to burn about 1.8 pounds of pellets per hour - about 8,500 BTUs per hour. Turning the knob to high allows the insert to burn 4.7 pounds of pellets per hour - about 39,000 BTUs per hour. Once set, the insert will continue to burn at this rate until shut off.
Thermostat Operation
This insert will operate with a low voltage thermostat. See Page 12 for instructions on installing the thermostat. Once installed, the thermostat will control the operation of the insert. Important: When connected to a thermostat, it is necessary to push the ignite button for the initial burn, when the electrical flow to the insert is interrupted, if the selector knob is turned to off (and then back on), or if the insert runs out of pellets and therefore shuts off. After the initial ignition sequence, when the thermostat calls for heat (the room temperature is less than the temperature set on the thermostat) and the heat selector knob is not in the off position, the insert will burn at the heat selector knob setting. The higher the setting, the quicker the room will heat up. Once the thermostat no longer calls for heat (the room is up to the desired temperature), the insert will continue to burn for one additional hour at the lowest setting. If the thermostat does not call for heat again during that hour, the insert will shut off. Dur- ing that hour, if the thermostat calls for heat again, the insert will again burn at the heat selector knob setting until the thermostat no longer calls for heat. If the insert shuts off after that hour it will relight when the thermostat calls for heat.
Shut Down
Normal - To turn the insert off, turn the heat selector knob to off. The fans will continue to operate until the control board completes the shut down cycle.
Power Outage - If the insert loses electrical power for less than 10 seconds it will continue to operate. If the power loss is greater than 10 seconds, the insert will go into the ignition sequence and normal operation when the power is restored. If the insert is connected to a thermostat, the insert will not start the ignition sequence until the thermostat calls for heat.
Paint Curing
This insert has been painted with a high temperature metallic paint. It leaves the factory dry to the touch, but completes the curing process as the insert is used. The paint will cure during the first few times the insert is burned. Also some parts of the appliance may be lightly coated with machining oil. Ventilate the house during these first firings as the paint and oil give off carbon dioxide and unpleasant odors. It is recommended that persons sensitive to an imbalance in the indoor air quality avoid the insert during the curing process.
Convection Blower Operation
Your Winslow??? PI40 insert comes equipped with a temperature activated convection blower that extracts heat from the insert. After the insert warms up, a heat activated switch will turn the fan on. The speed of the fan varies with the burn rate of the insert. The fan will continue to extract heat after the insert shuts off and until it is cooled down.
Operating Sounds
As the Winslow PI40 insert is burning, a number of normal operational sounds may be heard. Pellets can be heard sliding down the auger tube and into the burn pot. Also, the motor powering the auger can be heard as the control board calls for pellets. Occasionally a loud noise can be heard as the auger cuts a pellet in half. When the blowers come on, the sound of rushing air may be heard. The lower the burn rate the slower the fan operates. Hourly, the combustion fan will blow at a high speed to clean ash from the burn pot.
Pellet Fuel
Pellet fuel is made from sawdust and scrap wood from many different species of wood. Pellets are either 1/4??? or 5/16??? in diameter and vary in length (see Fuel Specifications on Page 5). The Winslow PI40 insert will burn either diameter pellets. Pellets made from hardwoods contain more ash than those made from softwoods. Minerals from ash and sand in the pellets form clinkers under the extreme temperatures in the burn pot. Try burning various brands of pellets until you find one that burns with minimum ash and clinkers.
Once you find a pellet brand that burns well, continue using this brand. High ash fuel increases the frequency of insert cleaning. Fuel with an excessive moisture content may jam the auger assembly.
Corn Fuel
Shelled corn can be burned in the Winslow PI40 insert when it is mixed with wood pellet fuel (see Fuel Specifications on Page 5). The mixture can contain a maximum of 50 percent corn. Burning corn may create more ash than wood pellets and may necessitate the need to clean the burn pot and glass more frequently.
CAUTIONS
INSTALLATION AND REPAIR SHOULD ONLY BE PERFORMED
BY A QUALIFIED SERVICE TECHNICIAN. DO NOT ATTEMPT TO
SERVICE THE APPLIANCE YOURSELF.
Avoid overfiring the insert - do not hand feed pellets to the appliance.
Never use gasoline,
For your safety, do not install or operate your Winslow PI40 insert without first reading and understanding this manual. Any installation or operation of the appliance deviating from that which is stated in this instruction manual WILL void the warranty and may be hazardous.
Due to high temperatures, the insert should be located out of traffic areas and away from furniture and draperies. Children and adults should be alerted to the hazards of high surface temperature and should stay away to avoid burns or clothing ignition. Young children should be carefully supervised when they are in the same room as the Winslow PI40 insert. Clothing or any other flammable material should not be placed on or near the insert. Any grill, panel, or glass removed for service MUST be replaced prior to operating the insert.
Do not operate appliance with the glass front removed, cracked, or broken. Replacement of the glass should be done by a quali- fied service technician.
Lennox Hearth Products, its employees, or any of its represen- tatives assume no responsibility for any damages caused by an inoperable, inadequate, or unsafe condition as a result of any improper operation, service, or installation procedures, whether direct or indirect.

Cleaning and Maintenance
Unplug and let the Winslow??? PI40 insert cool before performing any maintenance or cleaning. Some brands of pellets produce more ash and clinkers than others. Therefore the frequency of performing the follow- ing cleaning procedures depends to a great degree on the quality of the pellets burned. Not cleaning this unit will cause it to burn poorly and will void your insert???s warranty.

The combustion fan comes on at high speed once an hour to blow the byproducts of combustion out of the burn pot. However, the burn pot should be cleaned more thoroughly after burning about 10 bags of pel- lets. The burn pot has a number of holes in the bottom and sides that provide combustion air to the pellets. The extreme temperatures in the burn pot can cause the impurities in the pellets to form ash and clinkers. When the insert is cool, open the front door and lift out the cast iron burn pot. Scrape the inner bottom and sides of the pot with a screwdriver to remove all ash and clinkers from these surfaces. Make sure all the holes in the pot are open. Place the burn pot in the hole from which it was removed. Make sure the high side of the pot is rotated toward the front of the insert (see Figure 35). Push the burn pot down so surface A is tight against the steel supporting the pot. Do not substitute any other grate or pot for use in this insert.
Cleaning Glass
CAUTION: Do not open the front door when the fireplace insert is hot. To open the door, follow the first two steps listed in Front Door Removal on Page 23. Clean the glass using a soft cloth or paper towel and a household glass cleaner or gas stove window cleaner. A damp cloth with a small amount of ash from the firebox can also be used to clean the glass.
Cleaning the Heat Exchanger
CAUTION: Do not operate the heat exchange scraper when the insert is hot. Located at the center of the Grill on the top front of the insert is a bent rod that is attached to a scraper on the heat exchange tubes. To remove ash
Cleaning the Flue Gas Passageways
Cleaning the flue gas passageways should be done at least once a year. Burning high ash pellets may require this cleaning to be done more often. Clean these passageways only when the insert and ash are cold, do not start a fire in the vacuum cleaner by vacuuming up hot ash.
On each side of the insert there are two access covers (see B and C in Figure 36) that can be removed by unscrewing the two 5/32??? allen head screws. Insert a cleaning brush in the openings to loosen any ash build- up and use a vacuum cleaner to remove the loosened ash. Reinstall the covers when cleaning is complete.
Reinstall the ash drawer by inserting the drawer in the insert and refas- tening the left and right latches securely. Note that if the ash drawer does not seal tightly to the insert, the control board may detect a leak and shut the insert down.

Cleaning the Combustion Blower
To clean the combustion blower, unplug the insert from the power source and remove the six nuts labeled A in the drawing to the right with an 11/32??? wrench. After removing these nuts, the motor with fan attached can be pulled from the fan housing. The fan blades and the fan housing can be vacuumed once the motor is removed. When reinstalling the mo- tor, a new gasket may need to be installed between the motor and the fan housing. To complete the reinstallation, place the motor back on the fan housing and reinstall the six nuts. Make sure the motor???s green ground wire is secured under one of the nuts.
Cleaning the Vent Pipe
Soot and Flyash: Formation and Need for Removal
The products of combustion will contain small particles of flyash. The flyash will collect in the exhaust venting system and restrict the flow of the flue gases. Incomplete combustion, such as occurs during

Required Cleaning Schedule After Number Of Bags Burned:
Burn Pot = 10 bags
Ash Drawer = 50 bags
Traps = 50 bags
Flue Fan = 100 bags
Blower = 100 bags
Note: Cleaning schedule will vary depending on quality of pellets used. Burning high ash pellets will require more frequent cleaning.
Removing the Ash from the Firebox
CAUTION: Do not remove the ash when the insert or ash is hot. To remove the ash, swing open the left and right side doors and open the front door. Vacuum or scoop out the ash on the bottom and side of the firebox.
CAUTION: Disposal of ashes should be placed in a metal con- tainer with a tight fitting lid. The closed container should be placed on a

Cleaning the Convection Blower
To clean the convection blower, remove the left side door (see the following page). Disconnect the insert power cord from the electrical outlet. Loosen the two screws (A in Figure 39) securing the blower to the blower duct. Slide the blower toward the outside of the insert - disengaging it from the blower duct. A vacuum can be used to remove any dust accumulation on the blower???s blades or inside the blower duct. Caution should be used not to damage the blower???s blades during cleaning. To reinstall the blower, slide the blower back into the retaining lip B and retighten screws A.

Component Information
The following is a list of components and their functions.
Igniter
The Winslow??? PI40 insert comes equipped with an automatic igniter for lighting the fuel when the insert is in the lighting mode. The igniter superheats air that is pulled through the burn pot by the combustion blower to light the fuel. The igniter remains energized for the first seven minutes of the lighting sequence.
Vacuum Switch
The Winslow PI40 insert has a vacuum switch located behind the left door, fastened to the base (see A in Figure 44). If there is a leak in the firebox created by the front door being ajar or a blocked flue, the vacuum switch will sense it and cause the insert to go into a shutdown mode.
Auger and Auger Motor
The 1.25 RPM auger motor (B in Figure 22) turns the auger lifting pellets up the auger tube. The pellets are then dropped down a tube and into the firepot. The auger is controlled by the control board.
