Safety Warnings & Recommendations
* This manual is designed for the technician in conjunction with the owner’s manual. *
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
European Standards shall be complied with when installing this appliance.
Caution: Do not connect to any air distribution duct or system.
Warning: Parts of the appliance, especially the external surfaces, will be hot to touch when
in operation so use due care and the fire gloves provided. Never place wood, paper, furniture,
drapes or other combustible materials within 80cm (31”) of the front of the unit, 20cm (7”) 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. 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.
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. When filling fuel hopper, open lid on top of unit, check hopper for foreign objects, empty the
bag into the hopper, DO NOT OVER FILL, and ensure hopper lid closes completely. DO NOT use this
appliance as an incinerator. DO NOT use unsuitable and non recommended fuels, including liquid fuels.
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.
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: “SLIDER/DAMPER SETTING”.

Safety Warnings & Recommendations
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 been thoroughly cooled.
IMPORTANT: The door and ash drawer cover must be kept closed except during ignition, refueling and
removal of residue material to prevent fume spillage.
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.
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 (2.0-2.3 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 525 watts.
OPERATION: The door and ash drawer cover must be kept closed securely 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.
CAUTION: When operating during adverse weather, if the unit exhibits dramatic changes in combustion
stop using the unit immediately.
INSTALLATION: 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.
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.
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.

Safety Warnings & Recommendations
FRESH AIR: Outside Fresh Air connection is optional. Fresh Air must be connected to all units installed
in “Air Tight Homes” 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.
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 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

RATING LABEL LOCATION:
The rating label is located on the back of the hopper.
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

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
Figure 5: Use in conjunction with Table 2 for allowable exterior vent termination
locations.
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.

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 must conform with all local regulations, including those referring to regional, national or
European Standards. Use 80mm stainless steel vent pipe to exhaust the unit to the outside.
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 375 mm (15”) 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.
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 80mm (3”) vent pipe into the wall thimble. The pipe should install easily into the

place high temperature
silicone around the pipe
that passes through the thimble.
Installation
Figure 9: Straight through wall Installation.
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 91 to 152 cm (3 to 5 feet) 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.
• 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.

THERMOSTAT INSTALLATION:
1. Install the wall thermostat (12 or 24 Volt rated) in a location that is not to close too the unit but will
effectively heat the desired area.
2. Connect the Thermostat or Timer using an 2 x 18 gauge wire from the unit to the thermostat.
If the unit has been placed in the HI / LOW mode,
the unit will be taken to a low or idle setting when
the thermostat is not calling for heat. When the
thermostat calls for heat, the unit will go to the
setting that is displayed on the control board Heat
Indicator. If the heat in the room becomes to great,
the high limit switch may turn the stove off and
the switch will have to be manually reset. To reset
the high limit switch, remove the right cabinet
side. The switch is found behind the control panel.
Avoid setting off the high limit switch.
Figure 21: Thermostat wire placement.
SLIDER/DAMPER SETTING:
THE SLIDER / DAMPER MUST BE SET AT TIME OF INSTALLATION, IT IS USED TO REGULATE
THE AIRFLOW THROUGH THE PELLET STOVE.
A Qualified Service Technician or Installer must set the Slider Damper.
The slider damper should
be set only on a hot stove
(operating for thirty (30)
minutes or more) by placing
a Magnahelic Pressure Gauge
in the firebox (test port is
located in the center of the
stove just below the door
opening). Set the slider
damper so that the pressure
reads 0.18” to 0.20” W.C.
(44.8 to 49.8 Pa). Some
fuels may require higher
or lower settings. The
pressure readings are taken
through a hole in the front
of the firebox under the door,
using a Magnehelic Gauge.
20
Figure 22: Slider / Damper
Installation
The slider damper is located behind the left cab side. Undo the two (2) T-20 torx screws that hold the
inspection cover on the left side and remove.
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
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.
Figure 23: Efficient Flame.

Troubleshooting
DO NOT:
● Service the stove with wet hands. The stove is an electrical appliance, which may pose a shock hazard
if handled improperly. Only qualified technicians should deal with possible internal electrical failures.
● Do not remove from the firebox any screws without penetrating oil lubrication.
● Hold the ON / OFF BUTTON down. This is a momentary contact switch and can be damaged if held
down too long.
WHAT TO DO IF:
1. The stove will not start.
2. The stove will not operate when hot.
3. The exhaust blower will not function normally.
4. Light # 2 on Heat output bar flashing.
5. The auger motor will not function normally.
6. The 200 °F (93 °C) high limit temperature sensor has tripped.
7. The convection blower will not function normally.
8. Ignitor- the pellets will not light.
9. Control settings (Heat Level) has no effect on the fire.
10. The stove keeps going out.
*NOTE: All troubleshooting procedures should be carried out by qualified technicians or
installers.
1. The stove will not start.
üMake sure the stove is plugged in and the wall outlet is supplying power.
üPush the ON /OFF button. You may need to wait approximately 30 seconds for circuit board to initiate
the stove is on.
üIf the control board has been placed in the on/off thermostat mode, then turn the thermostat up to
call for heat.
üCheck the heat level indicator. - If the # 2 light is flashing refer to “4. Light # 2 on Heat output bar
flashing.”)
üCheck the fuse on the circuit board.
üIf the unit still does not start, contact your local service dealer for service.
2. The stove will not operate when hot.
üCheck the heat level indicator if a fire is not detected, or if the fire has gone out the #3 light will
flash because the exhaust temperature sensor’s contacts have opened.
üCheck the hopper for fuel.
üIncorrect air damper setting. - Excessive air may consume the fire too quickly before the next drop of
fuel, leaving completely unburned fuel in the burn pot liner. - Insufficient air will cause build up, further
restricting the air flow through the burn pot liner. This in turn will cause the fuel to burn cold and very
slowly. Fuel may build up and smother the fire. In this case clean the burn pot. (Note: the unit may
require a change to the vent system or installation of fresh air to correct air to fuel ratio
problems).
üCombustion blower failure. - The combustion blower is not turning fast enough to generate the proper
vacuum in the fire box. Visual check – is the blower motor turning.
üCheck the exhaust blower voltage across the blower wires (>=220V on #5 setting and >= 165V on
#1 setting). – Replace the Circuit Board if the Voltage reading is less than 160V. with a line voltage
>220V AC.
22
Troubleshooting
üCheck vacuum levels in the exhaust channel by bypassing the vacuum switch, then remove the vacuum
hose from vacuum switch. Check exhaust vacuum readings by placing the open end of the vacuum
hose on a Magnahelic Gauge (readings must be above 0.18” to 0.20” W.C. (44.8 to 49.8 Pa) on low
fire). If the motor fails to reach a 0.10” W.C. readings, then replace the combustion blower.
üPoor quality fuel – insufficient energy in the fuel to produce enough heat to keep the stove burning or
operational.
üExhaust temperature sensor failure. – Bypass sensor located on exhaust blower if stove now operates
properly, the unit may require cleaning or a new sensor. Contact your local dealer for service.
üThe burn pot liner may require cleaning. Build up in the burn pot will cause the unit to shut off.
üCheck the fuse on the circuit board.
üContact your local dealer for service.
3. The exhaust motor will not function normally.
üOpen the left side access panel; check all connections against the wiring diagram.
üSee “2. The stove will not operate when hot.” Section.
4. Light # 2 on Heat output bar flashing
(The Vacuum Switch contacts have opened for more than 15 sec.)
üPinch, break or blockage in vacuum hose - check hose for pinch points or damage, replace or re-route
as required. Blow out vacuum hose
üBlocked hose barb on exhaust channel - use a paper clip to clean out hose barb or remove the vacuum
hose from the vacuum switch and blow into the hose to remove blockage.
üBlocked exhaust / venting system - have stove and venting cleaned and inspected.
üSevere negative pressure in area where unit is installed - check the operation by opening a window,
does this solve the problem? If it does, install fresh air intake to unit or room. Venting system may
require vertical section to move termination into a low pressure zone.
üVacuum switch failure - bypass the vacuum switch, if this corrects the problem check for above problems
before replacing the vacuum switch.
üDamage to gray wires between circuit board and vacuum switch - inspect wires and connectors
üCombustion blower failure - the combustion blower is not turning fast enough to generate the proper
vacuum in the exhaust channel. Visual check; is the blower motor turning? Check the exhaust blower
voltage across the blower wires (>=220V on #5 setting and >= 165V on #1 setting). – Replace the
Circuit Board if the Voltage reading is less than 160V. with a line voltage >220V AC.
üCheck vacuum levels in the exhaust channel by bypassing the vacuum switch, then remove the Vacuum
hose from Vacuum Switch. Check exhaust vacuum readings by placing the open end of the Vacuum
Hose on a Magnahelic Gauge. (readings must be above .10” W.C. on low fire).
If the motor fails to reach a 0.10” W.C. readings, then replace the combustion blower
To reset Circuit Board after a trouble code - push the ON/OFF button
5. The auger motor will not function normally.
üThe burn pot liner may require cleaning. Build up in the burn pot will cause the unit to shut off.
üCheck for obstructions in the hopper system.
üEnsure door is closed and ash pan is closed. The auger motor will stop if there is not enough vacuum
in the stove.
üCall your local dealer for service.
Auger light flashes but auger motor does not turn at all.
23
Troubleshooting
üIf the auger gear box does not turn but the motor’s armature does try to spin then the auger is jammed.
– Try to break apart jam by poking at the jam through the drop tube. If this fails then empty the hopper
and remove the auger cover **remember to re-seal the cover after installation**
üCheck the fuse on the circuit board.
6. The 200 °F ( 93 °C) high limit temperature sensor has tripped.
üReset sensor and determine cause – was it convection blower failure or 160 °F ( 71 °C) temperature
sensor failure? Bypass the 160 °F ( 71 °C) sensor, does the convection blower come on high? If no,
replace the blower. If yes, replace sensor (located on the left side of the firewall).
üCheck the fuse on the circuit board.
7. The convection blower will not function normally.
üClean all grill openings at the back and below unit .
üPress the fan button; does the fan come on? Press again to verify that the blower turns on; if, not
contact your local dealer for service.
8. Ignitor- the pellets will not light.
(Everything else in the stove operates but the ignitor will not light the pellets.)
üMake sure the burn pot liner is up tight and square to the ignitor tube by pushing the burn pot back
against the ignitor tube.
üCheck to see if the exhaust blower is operating. If not, contact your local dealer for service.
üCheck the fuse on the circuit board.
NOTE: The ignitor should be bright orange in color. If not replace the ignitor.
9. Control settings (Heat Level) has no effect on the fire.
üNote: If the system light is flashing the control board has complete control of the unit. When the units
system light becomes solid then control of the unit is given back to the operator.
üIf there is no control of the heat level button make sure the thermostat is calling for heat.
üCall your local dealer for service.
10. The stove keeps going out.
a) If the stove goes out and leaves fresh unburned pellets or cigarette-like ashes in the burn pot liner,
the fire is going out before the stove shuts off.
üCheck to see that the slider / damper is in the correct position.
üTurn the heat level up slightly (poor quality pellets will require slightly higher settings).
üSet the auger trim till the #1 and #5 lights are illuminated.
b) If the stove goes out and there are partially burned pellets left in the burn pot liner, the stove has shut
down due to a lack of air, exhaust temperature, or power failure.
üAdjust the slider / damper.
üCheck to see if the stove needs a more complete cleaning.
üTurn the heat level up slightly (poor quality pellets will require slightly higher settings).
üDid the power go out?
üContact your local dealer for service.
