Introduction
* This manual is designed for the home owner in conjunction with the technical manual. *
Rating LabeL Location:
The rating label is located on the inside of the hopper.
FueL QuaLity:
Fuel quality is important, please read the following:
Your Enviro pellet stove has been designed to burn ¼” (6mm) dia wood pellets and other
organic fuels. DO NOT use this appliance as an incinerator. DO NOT use unsuitable and non
recommended fuels, including liquid fuels 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 fuel being
burned. As the heat output of various quality fuels differs, so will the performance and heat
output of the pellet stove.
CAUTION: It is important to select and use only fuel 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. The 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.
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 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.
FUEL FEED RATES: Due to different fuel densities and sizes, fuel feed rates may vary. This may require
an adjustment to the slider damper setting or to the auger feed trim setting.
Since Sherwood Industries Ltd. has no control over the quality of fuel that you use, we assume no liability
for your choice in fuels.
FILLING FUEL HOPPER: Open lid on top of unit, check hopper for foreign objects, empty the bag into
the hopper, and ensure hopper lid closes completely.
Store fuels at least 36” (1 m) away from the pellet stove.
WARNING: Parts of the appliance, especially the external surfaces, will be hot to touch
when in operation so use due care.
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.

Safety Warnings & Recommendations
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. All national and local regulations and shall be complied with
when operating this appliance.
Caution: Do not connect to any air distribution duct or system.
Warning: Never place wood, paper, furniture, drapes or other combustible materials within 48” (122cm)
of the front of the unit, 12” (30.5cm) from each side, and 4” (10cm) 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. 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. Extinguish
the fire in the burn pot liner with a cup of water and close the door. 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.
OPERATION: The door and ash drawer must be kept closed when the unit is in operation to prevent
fume spillage and for proper and safe operation of the pellet stove. Also ensure all gaskets on the door
are checked and replaced when necessary. Unit hot while in operation. Keep children, clothing and
furniture away. Contact may cause skin burns.
CAUTION: When operating during adverse weather, if the unit exhibits dramatic changes in combustion
stop using the unit immediately.
FUEL: This stove is designed and approved to only burn wood pellets of any quality
, corn, wheat, barley,
and grass. 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 CORDWOOD IS PROHIBITED
BY LAW. Do not burn garbage or flammable fluids such as gasoline, naptha or engine oil.
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.
Frequently check your stove and adjust the slider/damper as needed to ensure proper combustion. See:
SLideR/dampeR Setting”.
“
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.
The appliance, flue gas connector and the chimney flue require regular cleaning. Check them for blockage
prior to re-lighting after a prolonged shut down period.
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 surface, well away from all combustible materials pending final
disposal. If the ashes are disposed of by burial in soil or otherwise locally dispensed, they should be retained
in the closed container until all cinders have thoroughly cooled.

Safety Warnings & Recommendations
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 (4.2 Amps), 60 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 504 watts.
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.
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.
KEEP ASH PAN FREE OF RAW FUEL. DO NOT PLACE UNBURNED OR NEW PELLET FUEL IN ASH PAN.
A fire in the ash pan may occur.
INSTALLATION: Contact your local building or fire official to obtain a permit and any information on
installation restrictions and inspection requirements for your area.
Be sure to maintain the structural integrity of your home when passing a vent through walls, ceilings, or
roofs, and all construction meets local building codes. 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 existing construction doesn’t meet load capacity, suitable measures (e.g. load
distributing plate) must be taken to achieve it.
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: This unit uses large quantities of air for combustion; outside Fresh Air connection is strongly
recommended. Fresh Air 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 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.
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.
Soot or creosote may accumulate when the stove is operated under incorrect conditions such as a rich burn
(black tipped, lazy orange flames).
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.

Figure 7: Efficient Flame.
This unit is designed to operate within a negative pressure range of 0.15-0.17 inches of water column (37-42
Pa). This can be measured using a Magnahelic pressure gauge once the unit has been running on heat level 5
setting after one hour of burn time. This adjustment is necessary for varying venting configurations. The reading
can be taken from the ⅛” hole located on the right side of the Pedestal.
The Combustion Trim, Feed Trim and Fuel Type Functions can be used to compensate for varying fuel qualities.
Refer to the Owners Manual for circuit board operation.
If, after long periods of burning, the fire builds up or there is a build up of clinkers, this would be a sign that the
fuel quality is poor - this requires more air.
The easiest way to make sure that an efficient flame is achieved is to understand the characteristics of the fire.
• A tall, lazy flame with dark orange tips requires more air.
• A short, brisk flame, like a blowtorch, has too much air .
• 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, refer to Figure 7.
SPECIAL NOTES:
Fuel quality is a major factor in how the stove will operate. If the fuel has 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).

BURNER POT AND LINER (Checked Daily/Emptied Weekly)
This is the ‘pot’ where the pellets are burned. Only clean when the unit is cold.
Note: If, after long periods of burning, the fire continually builds up and overflows the burn pot or there
is a build up of clinkers, this is an indication that the pellet fuel quality is poor or the stove may need
cleaning. Check the stove for ash build up (clean if required) and adjust the slider / damper to produce
the proper clean combustion.
1. Open the door using the door handle located on the right-hand side of the stove.
2. Lift the lever on burn pot to unlock the fire grate and remove it.
3. The agitator locks at the right; rotate the top of the agitator towards the back of the firebox to unlock
it, slide it to the left, and lift it out of the burn pot liner.
4. Lift the burn pot liner out of the stove.
5. Lift the burn pot from the firebox by gently lifting it up at the front of the burn pot, then slide it out
from around the air intake tube and the ignitor cartridge. The ignitor is spring loaded to help with
removal and installation.
6. Remove any build up on the agitator (calcium build-ups are
common when burning corn). Using a metal scrapper, remove
material that has accumulated or is clogging the liner’s holes.
Then dispose of the scrapped ashes from the liner and from
inside the burn-pot.
7. Place the burn-pot back into the stove, there are hooks at the
front of the burn pot that sit in a mount in the firebox. Ensure
that the air intake tube and the ignitor cartridge. are properly
inserted into the burn pot.

Routine Cleaning and Maintenance
Heat eXcHangeR tubeS (Weekly)
The exchanger tube scraper rod handle is located above
the firebox door. Move the handle all the way in and out
a few times (ONLY WHEN THE UNIT IS COLD) in order
to clean away any fly ash that may have collected on
the heat exchanger tubes. As different types of pellets
produce different amounts of ash, cleaning of the tubes
should be done on a regular basis to enable the unit to
run efficiently.
DOOR GLASS CLEANING (Weekly)
Cleaning of the glass must only be done when stove is
cold. Open the door by lifting the handle. The glass can
be cleaned by wiping down the outside and inside of the
glass with a dry soft cloth.
If the glass has build up that can not be removed with only the cloth, clean the glass using paper towel
and a gas appliance glass cleaner, this may be purchased through most dealers. If a gas appliance glass
cleaner is not available, use a damp paper towel dipped in y ash to clean the glass. After the glass has
been cleaned use the dry soft cloth to wipe down the outside and inside of the glass.
Figure 9: M-55-FS Heat Exchanger Cleaning.
ASH PAN AND DOOR GASKETS (Weekly)
After extended use the gasketing may come loose. To repair this, glue the gasketing on using high-
temperature fiberglass gasket glue available from your local dealer. This is important to maintain an
airtight assembly.
ASH BOX (Weekly)
IMPORTANT: The unit must be OFF while the ash pan is removed.
The ash box is located behind the lower door (see Figure 10). To remove the ash box, lift the latch on the
right, open the ash box door, and lift it out.
Dump the ashes into a metal container stored away from combustibles. Monitor the ash level every week.
Remember that different pellet fuels will have different ash contents. Ash content is a good indication of
fuel efficiency and quality. Refer to “
the inside of the ash pan compartment inside the pedestal including the hole at the top back of the
compartment. Insert the ash box fully and close ash box door.
DO NOT PLACE UNBURNED OR RAW PELLET FUEL IN ASH PAN.
EXHAUST VENT (Biannually)
This vent should be cleaned every year or after two tons of pellets. We recommend contacting your
dealer for professional cleaning. To clean the vent pipe, tap lightly on the pipe to dislodge any loose ash.
Open the bottom of the “T” to dump the ash, then vacuum as much of the ash out of the vent pipe as
possible.
