PLANNING YOUR INSTALLATION
WARNINGCheck all local building and safety codes before
installation. The installation instructions and appro-
priate 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.
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.
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 compat-
ible with the insert’s electronics. The higher the quality of the gererator, 
the greater the chance that it is compatible with the insert.
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 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.
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.
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
SELECTING A LOCATION
CAUTIONThe 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 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  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.
4. If outside combustion air is required
5. Rooms where the installation is not allowed
