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
Acorrectinstallationiscriticalandimperativeforreducingfirehazardsand
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.
2. Local amendments
3. Is a permit required - cost. You may wish to contact your insurance
company to ask if they require this.

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.

OPERATION
Control Board
The control board regulates all functions of the stove. The following is a
list of the board’s components:
Note: Upon the stove’s initial light up, or if the stove has previously run
out of pellets, the auger feed tube may not contain a sufficient number of
pellets to allow the stove 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.
• Feeding light - lights up when the auger is feeding pellets into the
Burn-Pot.
• Ready Light - lights up when stove is ready to operate.
Igniting Light - lights up when the stove is in the ignition sequence.
• Start Button - is pushed to start the ignition sequence after the heat
selector knob is turned from off.
Heat Selector Knob - is turned to off to shut the stove off or turned to
a setting from 1 to high to regulate the burn
rate.
WARNINGS
• Igniter Fuse - six amp fuse to protect igniter heating element.
• Control Fuse - three amp fuse to protect the control board.
•NeveremptypelletsfromtheBurn-Potintothehopper.
Pellets that may appear to be cool may retain enough
heat to ignite other pellets resulting in smoke or fire
damage.

After the stove is burning (see lighting above), the heat selector knob
controls the pellet burn rate and the stove’s heat output. Turning the knob
to setting 1 allows the stove to burn about 1.8 pounds of pellets per hour
- about 8,500 BTUs per hour. Turning the knob to high allows the stove to
burn 4.7 pounds of pellets per hour - about 39,000 BTUs per hour. Once
set, the stove will continue to burn at this rate until shut off.

Thermostat Operation
Control Fuse
Igniter Fuse
This stove 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 stove. Important: When connected to a
thermostat, it is necessary to push the ignite button for the initial burn,
when the electrical flow to the stove is interrupted, if the selector knob
is turned to off (and then back on), or if the stove runs out of pellets and
thereforeshutsoff.Aftertheinitialignitionsequence,whenthethermostat
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
stove 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 stove 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 stove will shut off. Dur-
ing that hour, if the thermostat calls for heat again, the stove will again
burn at the heat selector knob setting until the thermostat no longer
calls for heat. If the stove shuts off after that hour it will relight when
the thermostat calls for heat.

Filling the Hopper
The hopper can be accessed by lifting the lid at the rear of the top of the
stove. The hopper will hold 60 pounds of pellets. Remove any contents
from the hopper and fill with pellets.

Once you find a pellet brand that burns well, continue using this brand.
High ash fuel increases the frequency of stove cleaning. Fuel with an
excessive moisture content may jam the auger assembly.
Shut Down
Normal - To turn the stove off, turn the heat selector knob to off. The
fans will continue to operate until the control board completes the shut
down cycle.
Corn Fuel
Shelled corn can be burned in the Winslow PS40 stove 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.

it will continue to operate. If the power loss is greater than 10 seconds,
the stove will go into the ignition sequence and normal operation when
the power is restored. If the stove is connected to a thermostat, the stove
will not start the ignition sequence until the thermostat calls for heat.
Paint Curing
CAUTIONS
This stove has been painted with a high temperature metallic paint. It
leaves the factory dry to the touch, but completes the curing process as
the stove is used. The paint will cure during the first few times the stove
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
stove during the curing process.
INSTALLATION AND REPAIR SHOULD ONLY BE PERFORMED
BY A QUALIFIED SERVICE TECHNICIAN. DO NOT ATTEMPT TO
SERVICE THE APPLIANCE YOURSELF.
Avoid overfiring the stove - do not hand feed pellets to the
appliance.
Never use gasoline, gasoline-type lantern fuel, kerosene,
charcoal lighter fluid, or similar liquids to start or fresh up a
fire in this heater. Keep all such liquids well away from the
heater while it is in use.
Convection Blower Operation
YourWinslow™PS40stovecomesequippedwithatemperatureactivated
convectionblowerthatextractsheatfromthestove.Afterthestovewarms
up, a heat activated switch will turn the fan on. The speed of the fan varies
with the burn rate of the stove. The fan will continue to extract heat after
the stove shuts off and until it is cooled down.
For your safety, do not install or operate your Winslow PS40
stove 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 war-
ranty and may be hazardous.
Operating Sounds
As the Winslow PS40 stove 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 blower will blow at a high speed
to clean ash from the Burn-Pot.
Due to high temperatures, the stove 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 PS40 stove. Clothing
oranyotherflammablematerialshouldnotbeplacedonornear
the stove. Any grill, panel, or glass removed for service MUST
be replaced prior to operating the stove.
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 PS40 stove 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.

Notes
•
Cleaning schedule will vary depending on quality of pellets used.
Burning high ash pellets will require more frequent cleaning.
Using a drop cloth is recommended as some ash may spill onto the
floor during the cleaning process
Reinstall the ash drawer by inserting the drawer in the stove and refas-
tening the left and right latches securely. Note that if the ash drawer
does not seal tightly to the stove, the control board may detect a leak
and shut the stove down.
•
Burn-Pot Cleaning
The combustion blower comes on at high speed once an hour to blow the
by-products of combustion out of the Burn-Pot. However, the Burn-Pot
shouldbecleanedmorethoroughlyafterburningabout10bagsofpellets.
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 stove 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 stove
(see Figure 43). 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 stove.

drawer, periodically, and replace if necessary. Inspect the die-cut gaskets
on the access covers (B and C in Figure 45A) and replace if necessary.
Cleaning the Heat Exchanger
CAUTION: Do not operate the heat exchange scraper when the
stove is hot. Located at the center of the grill on the top front of
the stove is a bent rod that is attached to a scraper on the heat
exchange tubes. To remove ash build-up and maintain efficient
heat extraction from the stove, this rod should be pulled in and
out at least once a week.

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 stove and ash are cold - do not
start a fire in the vacuum cleaner by vacuuming up hot ash. On each side
of the stove there are two access covers (see B and C in Figure 47) 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 an
approved ash vacuum cleaner to remove the loosened ash. Reinstall the
covers when cleaning is complete.

Cleaning the Vent Pipe
Soot and Fly-Ash: Formation and Need for Removal
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 occurs during start-up,
shutdown, or incorrect operation of the room heater will lead to some
soot formation which will collect in the exhaust venting system. The
exhaust venting system should be inspected at least once every year
to determine if cleaning is necessary. Sweep the pipe as needed. A tee
and clean-out in the vent system attached to the stove’s flue collar will
facilitate this cleaning.
Cleaning the Convection Blower
D

To clean the convection blower, remove the right side door (see the
following page). Disconnect the stove power cord from the electrical
outlet. Using a 5/32” allen wrench loosen the two screws (A in Figure
48) securing the blower to the blower duct (loosen screws only - do not
remove). Slide the blower to the rear - 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 tighten screws (A).

COMPONENT INFORMATION
Flue Outlet
The following is a list of components and their functions.
Igniter
The Winslow™ PS40 stove comes equipped with an automatic igniter
for lighting the fuel when the stove 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.
Air Intake
A
Vacuum Switch
Figure 51
The Winslow PS40 stove has a vacuum switch located behind the left
door, fastened to the pedestal base (see D in Figure 52). If a low pressure
is created in the firebox by a leak, opening the front door, a blocked flue,
or unsealed ash drawer, the vacuum switch will sense it and cause the
stove to go into a shutdown mode.
Auger and Auger Motor
The 1.25 RPM auger motor turns the auger, lifting pellets up the auger
tube. The pellets are then dropped down a tube and into the burn-pot.
The auger is controlled by the control board.
B
Over Temperature Snap Switch (Manual Reset)
(Opens at 225° F) This switch is installed on the convection blower (see F
inFigure53)andshutsthestovedownifitsensesexcessivetemperatures.
This snap switch has a reset button on it and will not allow the stove to
start up until the reset button has been pushed.
Proof of Fire Snap Switch
(Closes at 140°F) This switch is installed on the combustion blower
(see E in Figure 52) and shuts the stove down if it senses no fire in the
Burn-Pot.

Draft Adjuster
The Winslow™ PS40 stove has a draft adjuster located at the left side
of the stove directly in front of the combustion blower. Should the stove
installation require long runs of vent pipe, a situation may be created
where excessive combustion air is flowing through the firebox and
causing the fuel to burn faster than it can be delivered to the Burn-Pot.
Should this happen, the draft can be slowed down by the adjuster. The
stove is shipped with the adjuster in the fully open position. To slow the
draft down, loosen the 5/32” allen head screw (A in Figure 54) and move
the adjuster handle toward the center of the stove. Retighten the screw
when the desired adjustment is reached.
