PELLET QUALITY IS IMPORTANT, PLEASE READ THE
FOLLOWING PAGE
Your pellet stove has been designed to burn wood pellets only. Since there are many manufacturers of
wood pellets it is important to select pellets that are free of dirt or any impurities. The Pellet Fuel
Industries (P.F.I.) has established standards for wood pellet manufactures. We recommend the use of
pellets that meet or exceed these standards. Ask your dealer for a recommended pellet type.
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 DIFFER, SO WILL THE PERFORMANCE AND HEAT OUTPUT OF THE PELLET
STOVE.
Since Sherwood Industries Ltd. has no control over the quality of pellets that you use, we assume no
liability caused by the quality of wood pellets used.
P.F.I. PELLET STANDARDS:
Fines .....................................1% maximum through a 1/8” screen
Bulk Density ..........................40 lbs. per cubic foot minimum
Size .......................................1/4” to 3/8” diameter 1 – 1.5” long maximum
Ash Content ..........................1% maximum
Moisture Content...................8% maximum
Heat Content .........................approximately 8200 Btu per lb. minimum
Check the burn-pot liner periodically to ensure that the holes are not blocked with clinkers, (clinkers are
silica in the fuel that will form a hard mass during the burning process). If they are blocked, remove the
liner (when the unit is cold) and clean the clinkers out. The liner should be cleaned or scraped once
every 2-3 days depending on wood pellet quality. Clean the holes in the lines with a small pointed
object.
Store pellets at least 36” (1 m) away from the pellet stove.

IMPORTANT SAFETY DATA
To prevent the possibility of a fire, ensure that the appliance is properly installed by adhering to the
installation instructions. An ENVIROFIRE 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.
This unit is designed to burn pelletized wood fuel only. Do not use any other type of fuel, this will void
any warranties stated in this manual.
THE USE OF CORDWOOD IS PROHIBITED BY LAW.
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 slide damper located on the left side of the stove.
It is advisable to clean the exhaust vent bi-annually or every two tons of pellets.
The grounded electrical cord should be connected to a standard 115 volts, 60-hertz electrical outlet. 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 470 watts (3.91amps) for the EF-V
EVOLUTION.
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).
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.
Be sure to maintain the structural integrity of home when passing a vent through walls, ceilings, or
roofs.
The ash pan must be locked securely for proper and safe operation of the pellet stove.
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, we grant no warranty
implied or stated for the installation or maintenance of your stove, therefore, Sherwood Industries Ltd.
assumes no responsibility for any consequential damage.

WARNINGS AND RECOMMENDATIONS
A. Do not abuse the glass by striking or slamming the door shut.
B. Do not attempt to operate the stove with broken glass.
C. Do not attempt to open the door and clean the glass while the unit is in operation. 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.
D. Do not use abrasive cleaners to clean the surface or any part of the stove.
E. It is recommended that the unit be secured into its position in order to avoid any displacement.
F. Never use gasoline, gasoline-type lantern fuel, kerosene, or similar liquids to start the fire. Keep
all such liquids well away from the pellet stove while it is in use.
G. 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. The ashes should be retained in the closed
container until all cinders have thoroughly cooled before disposing of them.
H. Make sure the ash pan is closed tightly during the operation of the stove.
I. KEEP ASH PAN FREE OF RAW FUEL. DO NOT PLACE UNBURNED OR NEW PELLET
FUEL IN ASH PAN. A fire in the ash pan could be the result.
J. Fresh air intake is strongly recommended. Failure to install Intake air may result in the unit
smoking during power failures as well as improper combustion.
NOTE: Fresh air is mandatory on all units installed in “Mobile Homes” as well as “Air
Tight” homes.
AUTOMATIC SAFETY FEATURES OF YOUR PELLET STOVE
A. The stove will shut off when the fire goes out and the exhaust temperature drops below 120°F
(49°C).
B. The stove has a high temperature safety switch. If the temperature on the hopper reaches
200°F (93°C) the auger will automatically stop, and the stove will shut down when the exhaust
temperature cools. If this happens call your local dealer to reset the 200°F (93°C) high limit
switch. ALSO FIND THE REASONS WHY THE UNIT OVERHEATED.
C. If the power goes out, the unit will stop running. When the power comes back on, the stove will
not restart unless the exhaust temperature is still above 120°F (49 °C).

DECIDING WHERE TO LOCATE YOUR PELLET APPLIANCE
1. Check clearances to combustibles.
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” in diameter, or over 28 sq. inches 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.

VENT TERMINATION REQUIREMENTS
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 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. To 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. Vent terminal cannot be:
less than 4 feet (1.2 m) below
less than 4 feet (1.2 m) horizontally from, and
less than 1 foot (305 mm) above
Doors, window openings, or gravity/ventilation air inlet into building:
5. Distance from bottom termination and grade –12” (305 mm) minimum.(including exterior exhaust blower) 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. Distance from
bottom of termination and public walkways is 7 feet (2.1 m) minimum.
6. Distance to combustible materials is 2 feet (610 mm). This includes adjacent buildings, fences, protruding
parts of the structure, roof overhang, plants, shrubs, etc.
7. 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 Sherwood Industries LTD’s. control, we grant no
guarantee against such incidents.
IT IS RECOMMENDED THAT AN AUTHORIZED DEALER/INSTALLER INSTALL YOUR PELLET STOVE
