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 hopper top behind the surround panel.
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.
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 at least 36” (1 m) away from the pellet stove.
AUTOMATIC SAFETY FEATURES:
Your pellet Stove has the following safety features:
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 you will get a #2 ash code, and the stove will shut off
when the exhaust temperature cools. If this happens call your local dealer to reset the 200 °F (93 °C)
high limit switch. FIND THE REASONS WHY THE UNIT OVERHEATED.
C) The unit is equipped with a vacuum switch to monitor the venting and the build up of ash in the burn
pot; if either becomes blocked the vacuum switch will turn off the auger and the stove will shut off.

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. 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.
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 in the front of the unit under the ash pan.
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 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.
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 CORDWOOD IS PROHIBITED BY LAW.
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: OPERATING INSTRUCTIONS - SLIDER / DAMPER
SETTING.
CLEANING: There will be some build up of fly ash and small amounts of soot 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.
Introduction

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. The ashes should be retained in the closed container until all cinders
have thoroughly cooled before disposing of them.
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 120 volts, 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 (4.1 Amps) 500 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.
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.
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).

Introduction

Operating Instructions
SLIDER/DAMPER SETTING:
This is used to regulate the airflow through the pellet stove.
THE SLIDER / DAMPER MUST BE SET AT TIME OF INSTALLATION.
A Qualified Service Technician or Installer must set the Slider Damper.
• 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 moved to the left slightl, lessen the air flow into 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 moved to the right to give the fire more air.

Figure 1: Slider / damper positions.
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 – Push
Right
• A short, brisk flame, like a blowtorch, has too much air – Push
Left
• 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.

1. ON/OFF BUTTON: Used to turn the unit ON and OFF.
2. AUGER PULSE LIGHT: This light will flash in conjunction with the
auger.
3. HEAT OUTPUT INDICATOR: Shows the present heat output setting.
4. HEAT LEVEL ADJUSTMENT: When pressed, will change the heat
setting of the unit from low to high. the fan runs up and down with the
heat seting.
Notes:
• The convection blower speed will vary automatically with the feed rate.
• Due to varying fuel qualities this pellet stove may not operate on lower
Heat Level settings. If your unit goes out when on a low setting move the
heat level up to a higher setting.
• The lowest and highest heat levels on this pellet stove are used for
adjusting and accommodating for different pellet sizes and the varying
energy produced by the fuels. The size of the pellets will change the
volume of fuel being fed.
• The unit should be run at a setting where the least amount of cleaning of
the burn pot is needed.
The combustion exhaust blower is a variable speed blower controlled by the heat output setting. This
blower will increse or decrease the blower speed as the heat output setting is turned up or down.
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, move the Slider / Damper to the right slightly to
increase the air flow to the fire.
STOVE CONTROLS:
Figure 3: Control panel.

Operating Instructions
OPERATING YOUR PELLET STOVE:
PRE-BURN INSTRUCTIONS: The burn pot liner holes must be clear and the liner installed correctly
against the ignitor tube with the large vertical lip at the front for proper operation. Check the hopper for
enough pellets to start the unit.
DO NOT OPERATE THE UNIT WITH THE DOOR OR ASH PAN OPEN.
MANUAL MODE:
To START: Press the ON / OFF button. The stove will turn on, it may take fifteen (15) seconds for the
lights on the control board to come on. The Auger Light will flash with each pulse of the auger (the Auger
Feed Rate is pre-programmed during start-up). The Heat Level Indicator will show the Heat Level that
the stove will run at after start-up and can now be set.
If this is the first time the unit has been started or the unit has run out of fuel, a handful of pellet should
be placed in the burn pot.
To OPERATE: When a fire has been established (after approximately 10 - 15 minutes) and the Auger
Light will start to flash to the corresponding Heat Level setting. The Heat Level will now be at the desired
Heat Level Output setting.
The convection blower (room air blower) will turn on. The speed of this blower is controlled by the setting
of the heat level output indicator.
When operating on LOW HEAT LEVEL, the feed rate can be adjusted, using the auger trim, for different
quality fuels. These settings can be used if the fire keeps going out on low (for poor quality fuel) or if the
low setting is too hot for the room. This button is on the Motherboard behind the surround panel.
THERMOSTAT / SWITCH MODE:
INITIAL START-UP: See above
OPERATION - HI / LOW mode: When the thermostat contacts are closed the stove settings are
adjustable as per Manual Mode (see above). When the thermostat contacts open, the circuit board will
take control of the settings. The stove will drop down to a low burn until the thermostat contacts close
again. This low burn setting can be adjusted for different fuel qualities. The stove will come back to the
previous HEAT LEVEL setting when the thermostat contacts close again.
OPERATION – ON / OFF mode: When the thermostat contacts close, the unit will light automatically.
Once up to temperature, the stove operates the same as in manual mode (see above). When the
thermostat contacts open, the unit automatically begins its shutdown routine. The stove will re-light
when the thermostat contacts close again.
TURNING YOUR PELLET STOVE OFF:
• MANUAL and HI / LOW mode: To turn the unit OFF, simply press the ON / OFF button. This will stop
the feed of pellets. The blowers will continue to operate and cool the stove down. When cool enough,
the stove will turn off.
• ON / OFF mode: To turn the unit OFF, turn the thermostat down or off.
DO NOT unplug unit while Combustion fan is operating.
This will lead to smoke escaping from the stove.

Cleaning of the burn pot and liner must only be done when
Routine Cleaning and Maintenance
The following list of components should be inspected and maintained routinely to ensure that the
appliance is operating at its optimum and giving you excellent heat value:
Burn Pot Liner
Ignitor
Air Intake
Tube
Burn Pot
stove is cold. To remove the burn pot and burn pot liner, open the door located on the right-hand side
of the stove. Swing the door open. Lift the liner from the burn pot. Lift the burn pot from the firebox
by gently lifting up the front of the burn pot, then sliding the assembly from the air intake tube and the
ignitor cartridge.
This is the ‘pot’ where the pellets are burned. Every two to three days (when the unit is cold), remove
the burn-pot liner from the stove and inspected it to ensure proper air flow through the liner. Failure
to keep the liner clean may cause a build up of fuel past the burn pot liner and up the drop
tube. This will cause the auger to jam and may result in pellets burning in the drop tube and
hopper. 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. Place the burn-pot back
into the stove, making sure that the pipes are properly inserted into the burn pot. Place the liner back
into the burn-pot, making sure that the ignitor hole in the liner is aligned with the ignitor tube. Pushing
the liner up against the ignitor tube.
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.
DOOR LATCH (2-3 days)
Check the door latch every time the door is opened or closed to ensure proper engagment.
DOOR GLASS CLEANING (When needed)
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 glass cleaner, a special glass cleaner can be purchased through most dealers. If a glass cleaner
is not available, use a damp paper towel dipped in fly ash to clean the glass. After the glass has been
cleaned use the dry soft cloth to wiping down the outside and inside of the glass.
Figure 4: Burn pot assembly.

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 ENVIRO dealer. This is important to maintain
an airtight assembly.
ASH PAN (2-3 days)
The ash pan is located under the door. To remove the ash pan, simply turn the latch with a large standard
blade screwdriver and pull out towards the front. Dump the ashes into a metal container stored away
from combustibles. Vacuum the ash pan and inside the firebox. CAUTION: BECAUSE THE FLY ASH IS
VERY FINE, THE USE OF A FINE FILTER VACUUM BAG WILL BE REQUIRED TO PREVENT ASH FROM
BEING BLOWN BACK INTO THE ROOM. Please pay special attention that there are no hot ashes in the
firebox or there could be a possibility of a fire hazard inside the vacuum cleaner. Place all hot ashes into
a non-combustible container.
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 “INTRODUCTION - SAFETY WARNINGS
AND RECOMMENDATIONS” for disposal of ashes. It is important to latch the ashpan tightly whe re-
installing it.
DO NOT PLACE UNBURNED OR RAW PELLET FUEL IN ASH PAN.
HEAT EXCHANGER (weekly)
Clean away any fly ash that may have collected on the heat exchanger by opening the door and brushing
off the ns on the inside of the rebox. As different types of pellets produce different amounts of ash,
cleaning of the fins should be done on a regular basis to enable the unit to run efficiently.
FRESH AIR INTAKE (season)
Inspect periodically to be sure that it is not clogged with any foreign materials.
EXHAUST PASSAGES (season)
Removal of the firebox backing for bi-annual cleaning (refer to Figure 5):
Routine Cleaning and Maintenance
• Open the door by lifting the handle.
• Remove the burn pot and burn pot liner.
• Lubricate all screws with penetrating
oil.
• Remove the two (2) screws that hold each
brick liner retainer in place. Remove side
brick liners by sliding them forward then
out.
• Pull the center panel out.
• Vacuum and clean thoroughly.
Installation of firebox backing:
• Insert center panel with backing.
• Place the two (2) side panels back into the
firebox and reinstall the two (2) retainers
using two (2) screws on each side.
• Replace the burn pot and burn pot liner
• Close the glass door and secure.

Routine Cleaning and Maintenance
EXHAUST VENT (season)
This vent should be cleaned every year or after two (2) tons of pellets. We recommend contacting your
dealer for professional cleaning. To clean the vent pipe, run a chimney cleaning brush through the pipe.
Open the bottom of the “T” to dump the ash, then vacuum as much of the ash out of the vent pipe as
possible.
BLOWER MECHANISMS (season)
Unplug the stove and pull out the unit to access the two blowers. Vacuum all dust from motors and
lubricate the convection motor. Check gaskets and replace if needed.
ALL HINGES (season)
Check all the hinges on the unit to ensure proper movement.
POST SEASON CLEAN-UP
Once you are finished using the pellet appliance for the season, run the unit out of fuel and unplug the
stove for added electrical protection. It is very important that the stove be cleaned and serviced as stated
above.
CLEANING SURFACES
Enamel finishes and painted surfaces can be wiped down with a soft damp cloth. The paint on the firebox
panels may discolour or peel. This is due to extreme conditions applied to the paint and is in no way
covered by warranty.
FIREBOX PANEL
All surfaces should be brushed off periodically.
REPLACING DOOR GLASS
It is recommended that your ENVIRO dealer replace the glass if broken.
