Introduction
IMPORTANT SAFETY DATA:
Please read this entire Owner’s Manual before installing or operating your ENVIRO Pellet
Stove. Failure to follow these instructions may result in property damage, bodily injury or
even death. Any unauthorized modification of the appliance or use of replacement parts not
recommended by the manufacturer is prohibited.
Contact your local building or fire official to obtain a permit and any information on installation restrictions
and inspection requirements for your area. All local regulations, including those referring to national and
European Standards need to be complied with when installing this appliance.
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.
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.
Operating with door open could cause a fire inside the house as well as the release of carbon monoxide
into the living space.
Carbon monoxide is a colorless and odorless gas, to prevent it from poisoning you or your family know the
symptoms of carbon monoxide poisoning: headache, dizziness, weakness, sleepiness, nausea, vomiting,
and confusion. Carbon monoxide reduces the blood’s ability to carry oxygen. Low blood oxygen levels can
result in loss of consciousness and death.
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.
Consider all large air moving devices when installing your unit and provide room air accordingly. NOTE:
Extractor fans when operating in the same room or space as the appliance, may cause problems. Limited
air for combustion may result in poor performance, smoking and other side effects of poor combustion.
Soot or creosote may accumulate when the stove is operated under incorrect conditions such as an
extremely rich burn (black tipped, lazy orange flames).
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. This
appliance must be installed on a floor with an adequate load bearing capacity. If an existing construction
doesn’t meet these prerequisite, suitable measures (e.g. load distributing plate) shall be taken to achieve
it.
FRESH AIR: Outside Fresh Air connection is optional. Fresh Air must be connected to all units installed in
Mobile Homes and Air Tight Homes (R2000) or where required by local codes.
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.

Introduction
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, naphtha or engine oil. Unit hot while in operation. Keep children, clothing and furniture
away. Contact may cause skin burns.
Warning: Parts of the appliance, especially the external surfaces, will be hot to touch when in operation
and due care will need to be taken. Never place wood, paper, furniture, drapes or other combustible
materials within 80cm (31½”) of the front of the unit, 20cm (7⅞”) from each side, and 10cm (4”) from
the back of the unit. Do not let children or pets touch it when it is hot.
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.
FIRE EXTINGUISHER AND SMOKE DETECTION: All homes with a pellet burning stove should have
at least one fire extinguisher in a central location known to all in the household. Smoke detectors should
be installed and maintained in the room containing the stove when installing and operating a pellet
burning appliance. If it sounds the alarm, correct the cause but do not deactivate. You may choose to
relocate the smoke detection devise within the room; DO NOT REMOVE THE SMOKE DETECTOR FROM
THE ROOM.
CHIMNEY OR RUN AWAY FIRE: Call local fire department (or dial 911). Close the draft fully. Examine
the flue pipes, chimney, attic, and roof of the house, to see if any part has become hot enough to catch
fire. If necessary, spray with fire extinguisher or water from the garden hose. IMPORTANT: Do not
operate the stove again until you are certain the chimney and its lining have not been damaged.
FUEL: This pellet stove is designed and approved to only burn wood pellet fuel with up to 3% ash
content. Dirty fuel will adversely affect the operation and performance of the unit and may void the
warranty. Check with your dealer for fuel recommendations.
THE USE OF CORD WOOD IS PROHIBITED BY LAW.
SOOT and FLYASH: Formation and Need for Removal - The products of combustion will contain small
particles of flyash. The flyash will collect in the exhaust venting system and restrict the flow of flue gases.
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. The exhaust
venting system should be inspected at least once every year to determine if cleaning is necessary.
CREOSOTE: When wood is slowly burned it produces tar and other organic vapours and these combine
with expelled moisture to form creosote. The creosote vapours condense in the relatively cool chimney
flue associated with a slow burning fire. As a result, creosote residue accumulates on the flue lining.
When ignited this creosote can result in an extremely hot chimney fire.
CLEANING: There will be some build up of fly ash and small amounts of creosote in the exhaust. This
will vary due to the ash content of the fuel used and the operation of the stove. It is advisable to inspect
and clean the exhaust vent semi-annually or every two tons of pellets.
ASHES: Disposed ashes should be placed in a metal container with a tight fitting lid. The closed container
of ashes should be on a non-combustible floor 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 dispensed, they

5
should be retained in the closed container until all cinders have been thoroughly cooled.
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 110-120 volts, nominal average 2.0 Amps (4.1
Amps peak), 60 hertz electrical outlet and also must be accessible. Ensure the polarity to the outlet the unit will
be plugged into is correct as incorrect polarity can affect the unit’s operation. 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 184 watts (600 watts peak).
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.
KEEP ASH PAN FREE OF RAW FUEL.
Do not lace unburned fuel or new fuel in ash pan. A fire in the ash pan may occur.
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 connection is optional. Must be connected to all units installed in Mobile and “Air
Tight Homes” (R2000) or where required by local codes. Consider all large air moving devices when installing your
unit and provide fresh 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.

Introduction
RATING LABEL LOCATION:
The rating label is located on the back of the ash pan access cover.
PELLET QUALITY:
Pellet quality is important, please read the following:
Your Enviro pellet stove has been designed to burn wood pellets only. Do not use any other
type of fuel, as this will void any warranties stated in this manual.
The performance of your pellet stove is greatly affected by the type and quality of wood
pellets being burned. As the heat output of various quality wood pellets differs, so will the
performance and heat output of the pellet stove.
CAUTION: It is important to select and use only pellets that are dry and free of dirt or any impurities
such as high salt content. Dirty fuel will adversely affect the operation and performance of the unit
and will void the warranty. Pellet Fuel Industries (P. F. I.) has established standards for wood pellet
manufacturers. We recommend the use of pellets that meet or exceed these standards. Ask your dealer
for a recommended pellet type.
P. F. I. PELLET STANDARDS:
Fines (fine particles)......1% maximum through a ⅛” screen
Bulk Density..................40 pound per cubic foot minimum
Size..............................¼” to 5/16” diameter ½ – 1½” long maximum
Ash Content..................1% maximum (Premium grade)
..................3% maximum (Standard grade)
Moisture Content...........8% maximum
Heat Content.................approximately 8200 BTU per pound minimum
ASH: The ash content of the fuel and operation of your stove will directly determine the frequency of
cleaning. The use of high ash fuels may result in the stove needing to be cleaned daily. A low ash fuel
may allow longer intervals between cleaning.
CLINKERING: [clinkers are silica (sand) or other impurities in the fuel that will form a hard mass during
the burning process]. This hard mass will block the air flow through the Burn Pot Liner and affect the
performance of the stove. Any fuel, even approved types, may tend to clinker. Check the Burn-Pot Liner
daily to ensure that the holes are not blocked with clinkers. If they become blocked, remove the liner
(when the unit is cold) and clean/scrape the clinkers out. Clean the holes with a small pointed object if
required. Refer to the section Routine Cleaning and Maintenance.
PELLET FEED RATES: Due to different fuel densities and sizes, pellet feed rates may vary. This may
require an adjustment to the slider damper setting or to the auger feed trim setting on low.
Since Sherwood Industries Ltd. has no control over the quality of pellets that you use, we assume no
liability for your choice in wood pellets.
Store pellets in a dry area at least 36” (1 m) away from the pellet stove.

Installation
DECIDING WHERE TO LOCATE YOUR PELLET APPLIANCE:
1. Check the “Clearances to Combustibles” section for proper spacing.
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 wood stove 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.
7. Stove must sit on a non-combustible pad that extends six inches in front of the door or
the included hearth pad (50-2929).
UNPACKING AND REMOVING PELLET STOVE FROM PALLET
1. Start by removing the crating and unit bag, you will need a pry bar and hammer to remove the crating. A
sawzall can be used to cut the staples as well.
2. Loosen six screws securing Back Grill, once loose slide downwards and remove.
3. Use a 5/16” wrench or socket to remove the shipping bolts holding the unit to the pallet.

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.

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, and adjust
the leveling legs.
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.
5. Install the wall thimble as per the
instructions written on the thimble.
Maintain an effective vapour barrier in
accordance with local building codes.
6. Install a length of 3” (75 mm) or 4” (100
mm) vent pipe into the wall thimble. The
pipe should install easily into the thimble.
7. Connect the exhaust vent pipe to the
exhaust pipe on the stove. Seal the
connection with high temperature silicone.
8. Push the stove straight back, leaving a
minimum of 4” (10 cm) clearance from the
back of the stove to the wall. Seal the vent
pipe to the thimble with high temperature
silicone.
9. 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.

10. 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:
• It is recommended that horizontal through wall installations have 3 to 5 feet (91 to 152 cm) of vertical pipe in the
system to help naturally draft the unit in the event of extreme weather or a power outage.
• 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 draft 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.
• Follow vent manufacturer guidelines for installation of venting. High temp sealant must be used when connecting
vent pipe to the unit’s starter pipe. Improper seals at the vent joints may cause combustion by-products to leak
into the room where installed - seal as required.
THROUGH WALL VERTICAL RISE HORIZONTAL TERMINATION INSTALLATION - FREESTANDING:
A termination cap is always recommended for this type of install but a stainless steel termination hood or a 45°
elbow may be used in place of the cap.
Figure 14 is the recommended installation set up, venting length is negligible.
Figure 15 is the installation to use if there is a concrete or retaining wall in line with exhaust vent on a pellet stove.
The termination must be 12” (30 cm) from the outside wall and 12” (30 cm) above the ground.

through the ceiling fire stop. Maintain a 3” (7.5 cm)
distance to combustibles and keep attic insulation
away from the vent pipe. Maintain an effective
vapor barrier.
6. Finally, extend the pellet vent to go through the
roof flashing.
7. Ensure that the rain cap is approximately 24” (600
mm) above the roof.
To accomplish a outside vertical pipe installation, follow
steps 1 through 5 in the “INSIDE VERTICAL INSTALLATIONS -
FREESTANDING” section and then finish it by performing the
following (refer to Figure 17).
1. Install a tee with clean out on the outside of the house.
2. Install PL vent upward from the tee. Make sure that
you install support brackets to keep the vent straight
and secure.
3. Install ceiling thimble and secure the flashing as you
go through the roof.
