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.  
PLANNING YOUR INSTALLATION  
Questions To Ask Local Building Official  
Acorrectinstallationiscriticalandimperativeforreducingrehazardsand  
perilous conditions that can arise when wood pellet burning appliances  
are improperly installed. The installer must follow all of the manufactur-  
ers’ instructions.  
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.  
WARNING  
Check all local building and safety codes before  
installation.Theinstallationinstructionsandappro-  
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  
distributionduct.Failuretofollowtheseinstructions  
will void the manufacturers warranty.  
Installation/MaintenanceStandards-NationalFireProtectionAssocia-  
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  
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).  
• Pellet Fuel Storage  
Electrical codes:  
In USA, NEC, ANSI/NFPA 70 – Latest Edition  
In Canada, CSA C22.1 – Latest Edition  
• Aesthetic Considerations  
• Roof Design (rafter locations & roof pitch)  
• Room Traffic  
• Proximity to Combustibles  
• Electrical Wiring  
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 Page 12, Manufactured  
Home Requirements for additional requirements). These requirements  
must be met unless otherwise specified by state or local authorities.  
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.  
Electrical  
• The stove requires 120 volts AC for operation.  
• Maximum wattage is 700.  
• Igniter wattage is 400.  
NEGATIVE PRESSURE WARNING  
• Normal operating wattage is 300.  
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  
dangerouscondition, drawingcombustionby-productsintothehome. Be  
sure your home has adequate makeup air to eliminate negative pressures  
caused by the above-mentioned sources. Outside air connected to the  
appliance probably will not resolve such a problem as the stove is not the  
source of negative pressure. Lennox Hearth Products accepts no liability  
for damages resulting from negative pressures described here.  
Electrical Generator Operation  
Your Winslow™ PS40 stove can be powered with a gas driven electrical  
generator.However,thegenerator’selectricalregulatormaynotbecompat-  
ible with the stove’s electronics. The higher the quality of the generator,  
the greater the chance that it is compatible with the stove.  
WARNING  
Electrical grounding instructions: This appliance is  
equipped with a three-prong (grounding) plug for  
your protection against shock hazard and should  
be plugged directly into a properly grounded three-  
prong receptacle. Do not cut or remove the ground-  
ing prong from this plug. Do not route power cord  
under or in front of appliance.  
Ventilation Requirements - Provide adequate air for combustion. The  
freshairrequirementsofthisappliancemustbemetwithinthespacewhere  
it will be installed. Ventilation is essential when using a solid-fuel-burning  
heater. In well insulated and weather tight homes, it may inhibit the rate  
the exhaust flows through the venting system (caused by a shortage of  
air in the home). The lack of air is caused by many common household  
appliances which exhaust air from the home (such as a furnace, heat  
pump, air conditioner, clothes dryer, exhaust fans, fireplaces, and other  
fuel burning appliances). Also, the combustion process of this heater  
uses oxygen from inside the dwelling. If the available fresh air delivery  
in the dwelling is insufficient to support the demands of these appli-  
ances, problems can result (i.e. excessive negative pressure will result  
in performance problems. To correct this problem it may help to open  
a window (preferably on the windward side of the house) or install an  
outside combustion air duct to the appliance.

INSTALLATION  
Venting  
Horizontal  
This stove is approved for venting with Type L and Type PL pellet vent  
pipe listed to UL 641 and ULC S609. We recommend the use of venting  
products manufactured by Security Chimneys International. Single wall  
pipe cannot be used with this pellet stove. The stove’s flue collar is 3” in  
diameter. An approved wall thimble or approved ceiling firestop must be  
used when the pellet pipe passes through a combustible wall or ceiling.  
The stove’s combustion blower pressurizes and pushes flue gases out  
the pellet pipe. As a result, all pipe joints should be locked together or  
screwed with three screws if the pipe does not have a locking system  
and sealed with high temperature silicone. The pipe should be siliconed  
and fastened with three screws to the stove’s flue collar.  
1 foot  
minimum  
Where the venting may pass through a wall, or partition of combus-  
tible materials, the installation shall conform to CAN/CSA-B365. When  
installing the wall thimble and other venting components, follow the  
vent manufacturers instructions. Maintain an effective vapor barrier at  
the location where the chimney or other component penetrates to the  
exterior of the structure.  
Figure 13  
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.  
Horizontal and Up  
Through the Eave  
To aid in cleaning, whenever possible, the venting system should include  
a tee with clean out attached to the flue collar on the stove.  
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING  
SYSTEM OF THIS UNIT. DO NOT CONNECT THIS UNIT TO A  
CHIMNEY FLUE SERVING ANOTHER APPLIANCE.  
Horizontal installations that terminate without any vertical sections of  
pipe are approved; however, wind may direct flue gases toward the house  
causing discoloring problems. For this reason, horizontal and up 5 feet or  
horizontal and through the eave installations are recommended.

The Winslow PS40 stove can be operated manually or by thermostat. The  
stove comes from the factory wired to operate manually - see control  
board operation on the following page. A low voltage thermostat can be  
installed on the stove. To install the thermostat:  
1) Unplug the stove from the electrical outlet. Open the right side door  
and lift out the control board from its retaining brackets. Locate the  
light green wiring block at the bottom back of the board (see Figure  
21), loosen the two screws B at the back of the block and remove the  
U shaped jumper wire A protruding from the block.  
2) Insert a wire from the thermostat into one of the slots from which  
the jumper wire was removed. Repeat this process for the other  
thermostat wire.
