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 Mobile Home Installations on Page
11, for additional requirements). These requirements must be met unless
otherwise specified by state or local authorities.
Electrical
• The fireplace insert requires 120 volts AC for operation.
• Maximum wattage is 700.
• Igniter wattage is 400.
• Normal operating wattage is 300.
Electrical Generator Operation
Your Winslow™ PI40 insert can be powered with a gas driven electrical
gererator. However, the generator’s electrical regulator may not be compatible with the insert’s electronics. The higher the quality of the gererator,
the greater the chance that it is compatible with the insert.
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.

Weight - 270 pounds
Venting
This appliance is approved for venting with Type L and Type PL pellet vent
pipe. The flue collar on the fireplace insert accepts 3” diameter pipe. The
vent pipe can be installed vertically or horizontally (see Venting section
for recommended installations).
The combustion air for this fireplace insert is drawn through a pipe at
the lower rear of the fireplace insert. For mobile home installations a 2”
ID flex line or pipe can be attached to the fireplace insert’s air intake to
draw air from outside the house.
Thermostat
This fireplace insert can be operated manually or with a thermostat.
Lighting
This fireplace insert is equipped with an electric self ignitor for ease of
ignition.
Fuel Specifications
This insert 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 insert 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 insert. Any questions regarding pellet fuel
can be answered at the Pellet Fuels Institute (PFI), www.pelletheat.org.
CAUTION
THE USE OF UNAPPROVED, DIRTY, WET AND/OR
HIGH SALT CONTENT FUEL WILL VOID THE WARRANTY!
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.

INSTALLATION
Vent Termination Requirements:
If the insert is not vented vertically, the following apply:
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 instructions 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 3-4” increaser can be used to connect the
4” pipe to the 3” flue collar. The outside air pipe may run up the chimney,
horizontally, or down provided the structural integrity of the fireplace and
chimney system are maintained. 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.
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
insert 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
12” minimum. 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.

The recommended pipe installation is running the pellet pipe
from the insert all the way to the top of the chimney. However,
the pipe may terminate inside the chimney above the damper if
the chimney is sealed below the pellet pipe termination with a
block off panel (see Figure 10). The insert can also be vented
horizontally out the back of the fireplace, but a listed pellet pipe
thimble must be used if the pipe goes through a combustible wall
and the structural integrity of the fireplace and chimney system
must be maintained.
Insert Leveling
Inside the firebox is a bag of hardware with four 4”x 3/8” carriage
bolts. If the insert needs to be leveled, install one of these bolts
(from the bottom side) in the nuts at the left and right rear of the
base of the insert. Open the front door and remove the bolts screwed
into the nuts at the left and right front of the firebox floor.
From the bottom outside of the insert, install the remaining two
carriage bolts in the nuts from which the bolts were just removed.
A zero clearance front support is available to fill the space between
the insert and hearth.
Surround (Flange) Installation
To install the surround panels:
1. Remove the side doors (see Page 23
mounting brackets. Remove the speed nuts from the parts bag
found in the firebox. Install the six speed nuts (with the flat
surface forward) on the six surround mounting bracket holes,
three on each side of the insert. A flat-bladed screwdriver may
help in installing the nuts. See the expanded view in Figure
11A.
2. Screw the six 1/4” truss head screws partially into the speed
nuts (see A in Figure 11A).
3. The side surround panel with the small access door for the
control board goes on the right side of the insert (see Figures
11B and 11C
). Slide the slots in the side surround panels and
top surround panels behind the heads of the truss screws.
Tighten all six truss screws after shifting surround panels to
eliminate space between the side and top surround panels.
4. Install two spring clips approximately five inches from each
end of each of the three trim pieces. The spring clips should be
installed in the channel of the trim with the curved portion of
the clip to the front toward the rounded surface of the trim.
5. Place the longest trim piece with the rounded surface out along
the edge of the top surround panel with the spring clips slightly
behind the surround panel. Pull the trim forward, compressing
the spring clips, and slide the trim down onto the surround.
6. Insert the elbowed retainer in the mitred end of the side trim
pieces and fasten with flat screwdriver. Insert the other end
of the retainer in the end of the already installed top surround
trim and slide side trim onto the edge of the side surround
compressing the spring clips in the process. Repeat the same
steps for the other side trim. Fasten the elbowed retainer
securely in the top surround making a nice mitred corner.
) to access the surround
*The block off panel should be
air tight to ensure smoke does
not enter the house and to help
establish chimney draft when the
pipe does not terminate at the top
of the chimney.

Mobile Home Installations
The following steps are required for installation of the Winslow™
PI40 insert in mobile homes. See Figure 12.
1. Connecting the Winslow PI40 insert to outside combustion
air is optional, except in mobile home installations and when
required by local building codes. The insert’s air intake will
accept 2” 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.
2. The insert must be fastened to the hearth/floor using lag
screws. The screws can be inserted through the holes in
the base located behind the side doors. If the hearth is
concrete or masonry, use proper lag bolts and methods
designed for anchoring to masonry or concrete.
3. The insert must be grounded with a #8 or larger copper
wire.
WARNING: DO NOT INSTALL THIS INSERT IN A SLEEPING ROOM IN A MANUFACTURED HOME.
CAUTION: THE STRUCTURAL INTEGRITY OF THE
MANUFACTURED HOME FLOOR, WALL, AND CEILING/ROOF MUST BE MAINTAINED.
