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.

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 30 cm (12 in) 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.

OUTSIDE FRESH-AIR CONNECTION:
This Heater must have adequate air for proper combustion in the room that it is installed.
A Fresh-air intake is strongly recommended for all
installations. Failure to install intake air may result in improper
combustion as well as the unit smoking during power failures.
The inlet to the intake must be below and a minimum of 305mm
(12”) away from the unit exhaust outlet.
Outside fresh air is mandatory when installing this unit
in airtight homes and mobile homes.
When connecting to an outside fresh air source, do not use
plastic or combustible pipe. A 50mm minimum (2”) ID (inside
diameter) steel, aluminum or copper pipe should be used. It is
recommended, when you are installing a fresh air system, to
keep the number of bends in the pipe to a minimum.
EXHAUST AND FRESH AIR INTAKE LOCATIONS:
The Exhaust Starter Tube can be installed 2 ways:

Installation
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
thimble.
7. Install the fresh air intake (see OUTSIDE FRESH AIR CONNECTION).
8. Connect the exhaust vent pipe to the exhaust pipe on the stove. Seal the connection with high
temperature silicone.
9. Push the stove straight back, leaving a minimum of 100mm (4”) clearance from the back of the stove
to the wall. Seal the vent pipe to the thimble with high temperature silicone.
10. The pipe must extend at least 30 cm (12”) away from the building. If necessary, bring another
length of pipe 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.
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:
• 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.

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 23: Thermostat wire placement.
OPTIONAL SLIDER/DAMPER INSTALLATION:
NOTE: NOT APPLICABLE FOR GERMANY AND
NEW ZEALAND
If you wish to adjust the slider damper externally (NOT
REQUIRED), please follow the instructions below.
1. To install the OPTIONAL slider damper rod, remove the left cabinet
side and locate the slider damper plate. Install the 7/16” (11mm)
nut onto the slider damper rod, thread all the way to the end of
the threads on rod.
2. Slide rod through the hole in the slider damper plate and install
the 7/16” (11mm) clinching nut onto the rod and tighten completely
onto the slider damper plate.
3. Re-install the cabinet side. Install the black knob on the end of the

SLIDER/DAMPER SET-UP:
This is used to regulate the airflow through the pellet stove. The slider damper should be set
by a trained technician using magnehelic.
The slider damper is located behind the left side panel. To open the left side panel, undo the one screw
located in the upper front corner of the cabinet side between the louvers. Also loosen three screws down
the back of the side panel.
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.
Figure 26: Slider/Damper Plate in Unit.
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.
Figure 27: Efficient Flame.
• 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 (see Figure 27).
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).
IMPORTANT: Taking a reading of vacuum pressure inside the firebox with a magnehelic gauge should be
used to set the slider for best combustion. The slider damper should be set only on a hot stove (operating
for thirty (30) minutes or more) by using a Magnahelic Pressure Gauge to measuring the pressure in the
firebox. The best settings are a reading of approximately 27.4 - 29.9 Pa (0.11 - 0.12 inches of
water column) on the high fire setting. Some fuels may require higher or lower settings. The
reading can be taken from the 3 mm (”) hole located on the front of the unit below the ash shelf.

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.
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. Auger light flashes but auger motor does not turn at all
6. The 93°C (200°F) high limit temperature sensor has tripped.
7. The convection blower will not function normally.
8. Igniter- 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..
üIf the Control Board has been placed in the AUTO /OFF thermostat mode, then turn the thermostat up
or timer ON to call for heat.
üEnsure the burn pot liner is correctly placed in the burn pot
üCheck the Heat Level Indicator. - If the # 2 light is flashing (see the # 2 light is 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: 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 165 V. with a line voltage
>220 V 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 24.9 Pa (.10” W.C.) on low fire).
If the motor fails to reach a 24.9 Pa (.10” W.C.) readings, then replace the Combustion Blower.
22
Troubleshooting
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.
üCheck the fuse on the circuit board.
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 165 V. with a line voltage >220 V 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 24.9 Pa (.10” W.C.) on low fire).
If the motor fails to reach a 24.9 Pa (.10” W.C.) readings, then replace the Combustion Blower
To reset Circuit Board after a trouble code - push the ON/OFF button
5. Auger light flashes but auger motor does not turn at all.
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 93°C (200°F) high limit temperature sensor has tripped.
üReset sensor and determine cause – was it Convection Blower failure or 71°C (160°F) Temperature
Sensor failure? Bypass the 71°C (160°F) sensor, does the Convection blower come on high if not
replace the blower? If yes, replace sensor (located on the left side of the firewall).
üCheck the fuse on the circuit board.
23
Troubleshooting
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.
üEverything 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/Timer is calling for heat.
üCall your local dealer for service.
10. The stove keeps going out.
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.
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.
