Introduction
* This manual is designed for the technician in conjunction with the owner’s manual. *
RATING LABEL LOCATION:
The rating label is located on the inside of the hopper lid.
IMPORTANT SAFETY DATA:
Please read this entire Owner’s Manual before installing or operating this ENVIRO Pellet
Stove. Failure to follow these instructions may result in property damage, bodily injury
or even death. Contact your local building or fire official to obtain a permit and any information on
installation restrictions and inspection requirements for your area.
To prevent the possibility of a fire, ensure that the appliance is properly installed by adhering
to the installation instructions. An ENVIRO dealer will be happy to assist you in obtaining information
with regards to your local building codes and installation restrictions.
Be sure to maintain the structural integrity of the home when passing a vent through walls, ceilings, or
roofs.
The stove’s exhaust system works with negative combustion chamber pressure and a slightly positive
chimney pressure. It is very important to ensure that the exhaust system be sealed and airtight. The ash
pan and viewing door must be locked securely for proper and safe operation of the pellet stove.
Do not burn with insufficient combustion air. A periodic check is recommended to ensure proper
combustion air is admitted to the combustion chamber. Setting the proper combustion air is achieved by
adjusting the slider damper located on the left side of the stove.
When installing the stove in a mobile home, it must be electrically grounded to the steel chassis of the
home and bolted to the floor. Make sure that the structural integrity of the home is maintained and all
construction meets local building codes.
Minor soot or creosote may accumulate when the stove is operated under incorrect conditions such as an
extremely rich burn (black tipped, lazy orange flames).
If you have any questions with regard to your stove or the above-mentioned information, please feel free
to contact your local dealer for further clarification and comments.
SAFETY WARNINGS AND RECOMMENDATIONS:
Caution: Do not connect to any air distribution duct or system.
Do not burn garbage or flammable fluids such as gasoline, naptha or engine oil.
Unit hot while in operation. Keep children, clothing and furniture away. Contact
may cause skin burns.
SOOT: Operation of the stove with insufficient combustion air will result in the formation of soot which
will collect on the glass, the heat exchanger, the exhaust vent system, and may stain the outside of the
house. This is a dangerous situation and is inefficient. Frequently check your stove and adjust the slider/
damper as needed to ensure proper combustion. See: “INSTALLATION - SLIDER/DAMPER SETTING”.

Introduction
ELECTRICAL: The use of a surge protected power bar is recommended. The unit must be
grounded. The grounded electrical cord should be connected to a standard 220-240 volts (2.92-3.18
Amps), 50 hertz electrical outlet and also must be accessible. If this power cord should become damaged,
a replacement power cord must be purchased from the manufacturer or a qualified ENVIRO dealer. Be
careful that the electrical cord is not trapped under the appliance and that it is clear of any hot surfaces
or sharp edges. This unit’s maximum power requirement is 700 watts.
GLASS: Do not abuse the glass by striking or slamming the door. Do not attempt to operate the stove
with broken glass. The stove uses ceramic glass. Replacement glass must be purchased from an ENVIRO
dealer. Do not attempt to open the door and clean the glass while the unit is in operation or if glass is
hot. To clean the glass, use a soft cotton cloth and mild window cleaner, gas or wood stove glass cleaner,
or take a damp paper towel and dip into the fly ash. This is a very mild abrasive and will not damage the
glass.
FLAMMABLE LIQUIDS: Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter
fluid, or similar liquids to start or “freshen up” a fire in the heater. Keep all such liquids well away from
the heater while it is in use.
SMOKE DETECTOR: Smoke detectors should be installed and maintained in the structure when
installing and operating a pellet burning appliance.
OPERATION: The ash pan and door must be closed securely for proper and safe operation of the pellet
stove. Also ensure all gaskets on the door are checked and replaced when necessary.
INSTALLATION: Be sure to maintain the structural integrity of your home when passing a vent through
walls, ceilings, or roofs. It is recommended that the unit be secured into its position in order to avoid any
displacement.
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.
FRESH AIR: Outside Fresh Air is optional. Consider all large air moving devices when installing your unit
and provide room air accordingly. Limited air for combustion may result in poor performance, smoking
and other side effects of poor combustion.
If you have any questions with regards to your stove or the above-mentioned information, please feel
free to contact your local dealer for further clarification and comments.
SINCE SHERWOOD INDUSTRIES LTD. HAS NO CONTROL OVER THE INSTALLATION OF
YOUR STOVE, SHERWOOD INDUSTRIES LTD. GRANTS NO WARRANTY IMPLIED OR STATED
FOR THE INSTALLATION OR MAINTENANCE OF YOUR STOVE. THEREFORE, SHERWOOD
INDUSTRIES LTD. ASSUMES NO RESPONSIBILITY FOR ANY CONSEQUENTIAL DAMAGE(S).

Installation
DECIDING WHERE TO LOCATE YOUR PELLET APPLIANCE:
1. Check clearances to combustibles (see INSTALLATION - CLEARANCES TO COMBUSTIBLES and INSTALLATION - ALCOVE
CLEARANCES).
2. Do not obtain combustion air from an attic, garage or any unventilated space. Combustion air may
be obtained from a ventilated crawlspace.
3. Do not install the stove in a bedroom.
4. You can vent the stove through an exterior wall behind the unit or connect it to an existing masonry
or metal chimney (must be lined if the chimney is over 6” (15 cm) diameter, or over 28 inches² (180
cm²) cross sectional area). An interior vent can be used with approved pipe passing through the
ceiling and roof.
5. Locate the stove in a large and open room that is centrally located in the house. This will optimize
heat circulation.
6. The power cord is 8 feet (2.43 m) long and may require a grounded extension cord to reach the
nearest electrical outlet.
REMOVING PELLET STOVE FROM PALLET:
Remove screws from the two (2) hold-down brackets that secure the Windsor to the pallet. Lift the
brackets up to unhook from the chassis.

OUTSIDE FRESH-AIR CONNECTION:
Outside fresh air is mandatory when installing this unit
in airtight homes and mobile homes.
A Fresh-air intake is strongly recommended for all
installations. Failure to install intake air may result in improper
combustion as well as the unit smoking during power failures.
When connecting to an outside fresh air source, do not use
plastic or combustible pipe. A 2” minimum (51 mm) ID (inside
diameter) steel, aluminum or copper pipe should be used. It is
recommended, when you are installing a fresh air system, to
keep the number of bends in the pipe to a minimum.

hot enough to cause burns if touched by children. 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 appliance is vented directly through a wall, to create some natural draft to prevent the
possibility of smoke or odor during appliance shut down or power failure. This will keep exhaust from causing a
nuisance or hazard from exposing people or shrubs to high temperatures. In any case, the safest and preferred
venting method is to extend the vent through the roof vertically.
4. Distance from the bottom of the termination and grade is 12” (30 cm) minimum. This is conditional upon the
plants and nature of grade surface. The exhaust gases are hot enough to ignite grass, plants and shrubs located
in the vicinity of termination. The grade surface must not be lawn.
5. If the unit is incorrectly vented or the air to fuel mixture is out of balance, a slight discoloration of the exterior
of the house might occur. Since these factors are beyond the control of Sherwood Industries Ltd, we grant no
guarantee against such incidents.
NOTE: Venting terminals shall not be recessed into walls or siding.

CORNER THROUGH WALL INSTALLATION:
HORIZONTAL EXHAUST THROUGH WALL INSTALLATION:
Vent installation: install vent at clearances specified by the vent manufacturer.
A chimney connector shall not pass through an attic or roof space, closet or similar concealed spaces,
or a floor, or ceiling. Where passage through a wall or partition of combustible construction is desired,
the installation shall conform to CAN/CSA-B365 Installation Code for Solid-Fuel-Burning Appliances and
Equipment. Only use venting of L or PL type with an inside diameter of 3 or 4 inches (7.6 or 10.1 cm).
1. Choose a location for your stove that meets the requirements stated in this manual and allows
installation with the least amount of interference to house framing, plumbing, wiring, etc.
2. Install a non-combustible hearth pad (where necessary).
3. Place the appliance 15” (37.5 cm) away from the wall. If the stove is to be set on a hearth pad, set
the unit on it.
4. Locate the center of the exhaust pipe on the stove. Extend that line to the wall. Once you have located
the center point on the wall, refer to pellet vent manufacturer installation instructions for correct hole
size and clearance to combustibles.

• All sections of pipe must have three (3)
screws evenly spaced and all horizontal
and vertical vent sections located within the
house must have a bead of high temperature
silicone installed on the male end of the pipe
before installation to create a gas tight seal.
• The termination must be 12 inches (30 cm)
from the outside wall and 12 inches (30 cm)
above the ground.
• A 45° elbow with a rodent screen may be
used in place of the termination cap (or
stainless steel termination hood).

10. The pipe must extend
at least 12” (30 cm)
away from the building.
If necessary, bring
another length of pipe
(PL type) to the outside
of the home to connect
to the first section. Do
not forget to place high
temperature silicone
around the pipe that
passes through the
thimble.
11. Install a vertical pipe, or
if all requirements for
direct venting are met,
install vent termination.
The stainless steel cap
termination manufactured by the vent manufacturer is recommended. However, when the vent
terminates several feet above ground level and there are no trees, plants, etc. within several feet,
a 45° elbow can be used as termination. The elbow must be turned down to prevent rain from
entering.
NOTE:
• Some horizontal through wall installations may require a “T” and 3 to 5 feet (91 to 152 cm) of vertical
pipe outside the building to help naturally draft in the unit.
• This may be required if a proper burn cannot be maintained, after the stove has been tested and the
airflow set.
• This is due to the back pressure in the exhaust caused by airflow around the structure.

the fire.
• A tall, lazy flame with dark orange tips requires more air
– Open slider (pull out) slightly.
• A short, brisk flame, like a blowtorch, has too much air
– Close slider (push in) slightly.
• If the flame is in the middle of these two
characteristics with a bright yellow/orange, active
flame with no black tips then the air is set for proper
operation.
SPECIAL NOTES:
Pellet quality is a major factor in how the pellet stove will
operate. If the pellets have a high moisture content or
ash content the fire will be less efficient and has a higher
possibility of the fire building up and creating clinkers (hard
ash build-up). If this happens, pull the Slider Damper out
slightly to increase the air flow to the fire.
The combustion exhaust blower is a variable speed blower controlled by the heat output button. This
blower will decrease the vacuum pressure inside the stove and as the heat output button is turned down.
The vacuum pressure inside the firebox will increase as the combustion exhaust blower increases in
speed (higher heat output setting).
• If the fire should happen to go out and the heat output indicator has been set on the lowest setting,
the Slider Damper should be pushed in slightly, decreasing the air in the firebox.
• If, after long periods of burning, the fire builds up and overflows the burn pot or there is a build up
of clinkers, this would be a sign that the pellet quality is poor, this requires more primary air, the slider
damper must be pulled out to compensate. Pulling the slider damper out gives the fire more air.
The easiest way to make sure that an efficient flame is achieved is to understand the characteristics of
