WARNING

Improper installation, adjustment, alteration, ser­vice or maintenance can cause injury or property
damage. Refer to this manual. For assistance or
additional information consult a qualified installer,
service agency or the gas supplier.

WARNING

Do not attempt to alter or modify the construction of
the appliance or its components. Any modification
or alteration may void the warranty, certification
and listings of this unit.

1. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING
ANOTHER APPLIANCE.

2. Do not connect this appliance to air ducts or any air distribu­tion system.

3. DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING
SYSTEM OF THIS UNIT.

4. Do not use class B venting intended for gas appliances as a
chimney or connector pipe on a pellet-fired appliance.

5. The minimum clearances must be maintained for all com­bustible surfaces and materials including; furniture, carpet,
drapes, clothing, wood, papers, etc. Do not store combustibles
within this clearance space (see Clearances on Pages 6, 7
and 8).

6. INSTALLATION DISCLAIMER - It is imperative that the exhaust
venting system be installed correctly and sealed gas-tight
(not allowing exhaust to leak). Follow the vent manufacturer's
instructions for proper installation. Since Lennox Hearth
Products has no control over the installation of your stove,
Lennox Hearth Products grants no warranty, implied or stated
for the installation or maintenance of your stove and assumes
no responsibility for any consequential damage(s).

7. Burning any kind of fuel consumes oxygen. If outside air is
not ducted to the appliance, ensure that there is an adequate
source of fresh air available to the room where the appliance
is installed.

8. The appliance will not operate using natural draft, nor without
a power source for the blower and fuel feeding systems.

9. Never use gasoline, gasoline-type lantern fuel, kerosene,
charcoal lighter fluid, or similar liquids to start or “freshen
up” a fire in this heater. Keep all such liquids well away from
the heater while it is in use.

10. The authority having jurisdiction such as municipal build­ing department, fire department, fire prevention bureau, etc
should be consulted before installation to determine the need
to obtain a permit.

11. APPROVED FUEL: This appliance is designed specifically
for use only with pelletized wood fuels only. This appliance
is designed and approved for the burning of wood residue
pellets with up to 3% ash content. This appliance is NOT
approved to burn cardboard, nut hulls, cherry pits, corn, etc.

.

regardless if it is in pellet form. Failure to comply with this
restriction will void all warranties and the safety listing of
the stove. Consult with your Lennox Hearth Products dealer
for more information on approved pellet fuels.

12. These appliances are designed as supplemental heaters.
Therefore, it is advisable to have an alternate heat source
when installed in a dwelling.

13. CONTINUOUS OPERATION: When operated correctly, this
appliance cannot be overfired. Continuous operation at a
maximum burn can, however, shorten the life of the electri­cal components (blowers, motors and electronic controls)
and is not recommended. Typical approved operation would
include running at the low to mid range setting with occasional
running on the maximum setting during the coldest periods
of the winter. DO NOT OVER-FIRE THIS STOVE. Follow all
instructions regarding the proper use of this stove.

14.CAUTION: NEVER PUT FINGERS NEAR AUGER. Pellet fuel is
fed to the burn-pot by a screw auger. This auger is driven by
a high torque motor. The auger is capable of doing serious
harm to fingers. Keep pellets in the hopper at all times and
keep fingers away from auger. The auger can start and stop
automatically at any time while the stove is running.

15. CAUTION: HOT WHILE IN OPERATION. An appliance hot
enough to warm your home can severely burn anyone touching
it. Keep children, clothing and furniture away. Contact may
cause skin burns. Do not let children touch the appliance.
Train them to stay a safe distance from the appliance.

16. FLY ASH BUILD-UP: For all wood pellet fuel-burning heaters,
the combustion gases will contain small particles of fly-ash.
This will vary due to the ash content of the fuel being burned.
Over time, the fly-ash will collect in the exhaust venting
system and restrict the flow of the flue gases. The exhaust
venting system should be inspected regularly and cleaned
as necessary.

17. SOOT FORMATION: Incomplete combustion, such as occurs
during startup, shutdown, or incorrect operation of the room
heater will lead to some soot formation which will collect in
the exhaust venting system. A precautionary inspection on
a regular basis is advisable to determine the necessity of
cleaning. The exhaust venting system should be inspected
regularly and cleaned as necessary.

18. DISPOSAL OF ASHES: Ashes should be placed in a metal
container with a tight-fitting lid. The closed container of
ashes should be placed on a noncombustible floor or on the
ground, well away from all combustible materials, pending
final disposal. If the ashes are disposed of by burial in soil
or otherwise locally dispersed, they should be retained in
the closed container until all cinders have been thoroughly
cooled.

19. The instructions must be strictly adhered to. Do not use
makeshift methods or compromise in the installation.

20. Do not abuse the door glass by striking, slamming or similar
trauma. Do not operate the stove with the glass removed,
cracked or broken.

21. SAVE THESE INSTRUCTIONS.

22. See the listing label on the appliance.

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 manufactur­ers’ instructions.

WARNING

Check all local building and safety codes before
installation. The installation instructions and appro­priate code requirements must be followed exactly
and without compromise. Alterations to the stove are
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.

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 require­ments in your area.

Installation / Maintenance Standards - National Fire Protection Associa­tion – The primary NFPA standard that refers to installation and main­tenance of pellet appliances and venting is NFPA 211 – Latest Edition:
Chimneys, Fireplaces, Vents, and Solid Fuel appliances.

SELECTING A LOCATION

The installation of this appliance must conform to local codes and appli­cable state and federal requirements. Familiarity with these requirements
before installation is essential. Important considerations to discuss with
local building officials include:

Applicable codes (i.e. Uniform Mechanical Code, State or Regional

1.
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 Page 12, Manufactured
Home Requirements for additional requirements). These requirements
must be met unless otherwise specified by state or local authorities.

Electrical

• The stove requires 120 volts AC for operation.

• Maximum wattage is 700.

• Igniter wattage is 400.

• Normal operating wattage is 300.

Electrical Generator Operation

Your Winslow™ PS40 stove can be powered with a gas driven electrical
generator. However, the generator’s electrical regulator may not be compat­ible 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 three­prong receptacle. Do not cut or remove the ground­ing prong from this plug. Do not route power cord
under or in front of appliance.

2. Local amendments

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

4. If outside combustion air is required

5. Rooms where the installation is not allowed

4

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 nega­tive pressure in the same room as the heating appliance. This can create
dangerous condition, drawing combustion by-products into the home. 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.

Ventilation Requirements - Provide adequate air for combustion. The

fresh air requirements of this appliance must be met within the space where
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 appli­ances, 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.

FEATURES AND SPECIFICATIONS

Installation Options

• Residential

• Vented vertical and horizontal (see venting instructions)

• Manufactured home and mobile home

• Thermostat or manual operation

• Bedrooms

Heating

• Max. feed rate is 4.7 pounds/hour or 39,500 BTU/hour

• Min. feed rate is 1.8 pounds/hour or 15,120 BTU/hour

Venting

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.. The flue
collar on the stove accepts 3” diameter pipe.

The combustion air for this stove is drawn through a pipe at the lower
rear of the stove. For mobile home installations a 3” ID flex line or pipe
must be attached to the stove’s air intake to draw air from outside the
house. The vent pipe can be installed vertically or horizontally (see Venting
section for recommended installations).

Wood pellets manufactured to the pellet fuels institute (P.F.I.) certification
standard are available in two grades, Standard and Premium. The primary
difference between the two is the ash content of the pellets.

The P.F.I. specification for standard grade and premium grade residential
pellet fuel is as follows:

• CHLORIDES (Salt): Less than 300 p.p.m. to avoid stove and vent
rusting.

• BULK DENSITY: 40 lb. / Cu. Ft. minimum

• MOISTURE CONTENT: 8% maximum

• ASH CONTENT: < 3% maximum (standard grade) < 1% maximum
(premium grade)

• FINES: 0.5% maximum through a 1/8” screen

• BTU CONTENT: There are a number of variations in pellet fuels that are
not included in PFI standards. For example, BTU (heat value) content
may range from just under 8,000 to almost 9,000 Btu, depending upon
species and region of the country and other variables.

Corn Specifications: Use only clean-shelled corn with a moisture content
less than 15% and approximate fuel value of 7000 BTU/lb (16,200 kJ/kg).
Do not attempt to burn corn with higher moisture content or burn lesser
grade fuels. Do not burn other types of agricultural pellets or by-products
(alfalfa, cherry pits, olive pits, nut shells, etc.) as they are not permitted
to be burned in these appliances.

Note: When installing this stove at altitudes of 4000 feet and above, we
suggest the use of 4” pellet vent.

Thermostat

This stove can be operated manually or with a thermostat.

Lighting

This stove is equipped with an electric self igniter for ease of ignition.

Fuel Specifications

This stove is designed to burn wood pellet fuel. In addition, a corn/wood
pellet mixture, with a maximum of 50 percent corn can be burned. Burning
any other fuel that is not approved for use with this appliance will void the
appliance warranty. IMPORTANT: The corn/wood mix needs to be mixed

evenly before being put in the Winslow™ pellet stove hopper.

Wood Pellet Specifications: This appliance has been designed to burn

wood residue pellets with up to 3% ash content. Dirty fuel will adversely
affect the performance of the stove. Any questions regarding pellet fuel

CAUTION

THE USE OF UNAPPROVED, DIRTY, WET AND/OR
HIGH SALT CONTENT FUEL WILL VOID THE WAR­RANTY!

1. Do not terminate the vent in any enclosed or semi-enclosed areas
such as a carport, garage, attic, crawlspace, narrow walkway, closely
fenced area, under a sundeck or porch, or any location that can build
up a concentration of fumes such as stairwells, covered breezeway,
etc.

2. Vent surfaces can become hot enough to cause burns if touched.
Non-combustible shielding or guards may be required.

3. Termination must exhaust above the inlet elevation. It is recommended
that at least five feet of vertical pipe be installed outside when the
stove is vented directly through a wall. This will create a natural draft
to prevent the possibility of smoke or odor during appliance shut
down or power failure and avoid exposing people or shrubs to high
temperatures.

4. The vent should terminate no less than four feet below, no less than
four feet horizontally from and no less than one foot above doors and
windows, or gravity/ventilation air inlets into the building.

5. The distance between the bottom of termination and grade should be
a minimum of 12” (305 mm). The distance between the bottom of
the termination and a public walkway should be a minimum of seven
feet.

6. Locate the vent termination at least two feet away from combustible
materials such as shrubs, plants, grass, fences, roof overhangs and
adjacent buildings.

INSTALLATION

Venting

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.

Where the venting may pass through a wall, or partition of combus­tible 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.

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.

To aid in cleaning, whenever possible, the venting system should include
a tee with clean out attached to the flue collar on the stove.

If the length of pipe exceeds 15 feet, 4 inch pipe rather than 3 inch vent
pipe should be used.

Connecting the Winslow PS40 stove to outside combustion air is optional,
except in mobile home installations and when required by local build­ing codes. The stove’s air intake will accept 3” ID pipe to accommodate
outside air installations. The air intake on the exterior of the home should
always be located substantially below the flue termination and terminate
with a cover to keep out weather and pests.

Thermostat installation

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.

Retain the jumper wire for future reinstallation. See Page 19 for thermostat
operation instructions.

IMPORTANT NOTE: Install the thermostat per the manufacturers
instructions, provided with the thermostat. Failure to follow
manufacturers instructions could result in a malfunction. Pay
special attention to the thermostat location requirements. If the
location requirements are not adhered to the appliance, erratic
operation or failure may occur.

Control Board

The control board regulates all functions of the stove. The following is a
list of the board’s components:

•

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.

•

Igniter Fuse - six amp fuse to protect igniter heating element.

•

Control Fuse - three amp fuse to protect the control board.

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 stove will feed pellets cyclically into the Burn-Pot, the combustion
blower 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 stove will begin burning at the level indicated by the
heat selector knob.

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.

WARNINGS

• Never empty pellets from the Burn-Pot into the hopper.
Pellets that may appear to be cool may retain enough
heat to ignite other pellets resulting in smoke or fire
damage.

• 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.

Figure 42

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.

Lighting

1. Turn the heat selector knob (see Figure 42) to the heat level desired

- 1 through high - and the ready light will turn green.

Manual Operation

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

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
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
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. Dur­ing 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.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

19

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.

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.

Corn Fuel

Power Outage - If the stove loses electrical power for less than 10 seconds

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

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.

Convection Blower Operation

Your Winslow™ PS40 stove comes equipped with a temperature activated
convection blower that extracts heat from the stove. After the stove warms
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.

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.

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.

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.

CAUTIONS

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.

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 war­ranty and may be hazardous.

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
or any other flammable material should not be placed on or near
the stove. Any grill, panel, or glass removed for service MUST
be replaced prior to operating the stove.

Do not operate appliance with the glass front removed, cracked,
or broken. Replacement of the glass should be done by a quali­fied service technician.

Lennox Hearth Products, its employees, or any of its represen­tatives 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.

20

The appliance, when installed, must be electrically grounded in
accordance with local codes or, in the absence of local codes,
with the National Electrical Code, ANSI/NFPA 70.

CLEANING AND MAINTENANCE

A

Latch

B

IMPORTANT CAUTIONS:

• UNPLUG POWER CORD AND ENSURE APPLIANCE IS COLD
BEFORE PERFORMING ANY MAINTENANCE WORK.

• Some brands of pellets produce more ash and clinkers than
others. Therefore the frequency of performing the following
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 warranty for this appliance.

• When removing ash build-up, use an approved ash vacuum
only. A cleaning brush can be used to loosen any ash build-up
before vacuuming. DO NOT USE A STANDARD HOUSEHOLD
VACUUM OR “SHOP VAC” AS THE FILTERS WILL LEAK THE
FINE PARTICLES OF ASH INTO THE HOME.

Cleaning Glass

CAUTION: Do not open the front door when the stove is hot.
To open the door, follow the first two steps listed in Front Door
Removal (see Page 24). Clean the glass using a soft cloth or
paper towel and household glass cleaner or wood stove window
cleaner. A damp cloth with a small amount of ash from the

firebox can also be used to clean the glass.

Ash Drawer Removal and Cleaning

CAUTION: Do not remove the ash drawer when the stove is hot.
To remove the ash drawer, swing open the left and right side
doors. Rotate the lever on latch B (see Figure 44) out from the
stove to release the ash drawer. Do the same with the latch
on the right side of the stove. Pull the ash drawer forward and
away from the stove.

Required Cleaning Schedule After Number Of Bags Burned:

Burn-Pot = 10 bags
Ash Drawer = 50 bags
Flue passageways = 50 bags
Combustion Blower = 100 bags
Blower = 100 bags

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

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
should be cleaned more thoroughly after burning about 10 bags of pellets.
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.

CAUTION: Disposal of Ashes - Ashes should be placed in a
metal container with a tight fitting lid. The closed container
should be placed on a non-combustible floor or the ground - well
away from all combustible materials, pending final disposal. If
the ashes are disposed of by burial in soil or otherwise locally
dispersed, they should be retained in the closed container until

all cinders have been thoroughly cooled.

Reinstall the ash drawer by inserting the drawer in the stove and refas­tening 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.

Inspect Gaskets

Inspect the condition of the rope gasket around the door, window and ash
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.

There are also two more access holes located behind the ash drawer.
Remove the ash drawer (see previous page) and loosen the two 5/16”
screws with a 1/2” socket or wrench, the screws are shown as D in

Figure 45

and vacuum to clean the ash. Rotate the covers back over the holes and
tighten the screws.

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).

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.

Vacuum Switch

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.

Over Temperature Snap Switch (Manual Reset)

(Opens at 225° F) This switch is installed on the convection blower (see F
in Figure 53) and shuts the stove down if it senses excessive temperatures.
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.

Convection Blower Snap Switch

(Closes at 120°F) This switch is installed on the right rear of the firebox and
turns the convection blower on when the stove gets up to temperature.

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.
