Introduction
* This manual is designed for the technician in conjunction with the owner’s manual. *
RATING LABEL LOCATION:
The rating label is located on the back of the unit.
IMPORTANT SAFETY DATA:
Please read this entire Owner’s Manual before installing or operating this 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.
Be sure to maintain the structural integrity of the home when passing a vent through walls, ceilings, or
roofs.
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.
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 and all
construction meets local building codes.
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 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 or 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.
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: “INSTALLATION SLIDER/DAMPER SETTING”.

Introduction
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,, nominal
average 0.8 Amps (1.4 Amps peak), 50 hertz electrical outlet and also must be accessible. If this power
cord should become damaged, a replacement power cord must be purchased from 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 184 watts (322 watts peak).
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.
INSTALLATION: 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.
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: Outside Fresh Air is optional. Consider all large air moving devices when installing your unit
and provide room air accordingly. Limited air for combustion may result in poor performance, smoking
and other side effects of poor combustion.
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).

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” (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
nearest electrical outlet.
REMOVING PELLET STOVE FROM PALLET:
1. Remove the right and left hand cabinet sides by
loosening the three (3) T-20 Torx screws on the
back of the each panel.
2. Remove the screw located on the front of the
cabinet side, below the louvers and loosen the
screw behind the ash door.
3. Using a 5/16” socket of flat head screwdriver,
remove the three (3) wood screws that are holding
the bottom of the stove to the pallet. There is one
(1) screw behind each side panel and one (1) at the
back behind the back grill.
4. Close the side panels.
5. Install the four (4) leveling legs into the nuts in the
base.

a concentration of
fumes such as stairwells, covered breezeway, etc.
(Termination not allowed)
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.
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.

Installation
10. 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 3 to 5 feet (91 to 152 cm) 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.
THROUGH WALL WITH VERTICAL RISE AND HORIZONTAL TERMINATION INSTALLATION - FREESTANDING:
A 45° elbow with a rodent screen may be used in place of the termination cap (or stainless steel
termination hood).
Figure 10 is the recommended installation set up.
Figure 11 is the installation to use if there is a concrete or retaining wall in line with exhaust vent on
a pellet stove. The termination must be 12” (30 cm) from the outside wall and 12” (30 cm) above the
ground.

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).
Figure 26: Efficient Flame.
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 best settings are a reading of approximately
0.11 0.12 inches of water column (27.4 - 29.9 Pa) on the high fire setting. Some fuels may
require higher or lower settings. The reading can be taken from the 1⁄8” (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 200 °F (93 °C) 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 ON /OFF thermostat mode, then turn the thermostat up to
call for heat.
üCheck the Heat Level Indicator. - If the # 2 light is flashing (see the # 2 light is flashing)
üCheck the fuses on the circuit board (see “Troubleshooting - Fuses”).
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 >= 150V on
#1 setting). – Replace the Circuit Board if the Voltage reading is less than 150 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 .10” W.C. on low fire).
If the motor fails to reach a 0.10” 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 fuses on the circuit board (see “Troubleshooting - Fuses”).
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 >= 150V on #1 setting). – Replace the
Circuit Board if the Voltage reading is less than 150 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 .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. 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 fuses on the circuit board (see “Troubleshooting - Fuses”).
6. The 200 °F ( 93 °C) high limit temperature sensor has tripped.
üReset sensor and determine cause – was it Convection Blower failure
üCheck the fuses on the circuit board (see “Troubleshooting - Fuses”).
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 fuses on the circuit board (see “Troubleshooting - Fuses”).
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.
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 (set with a magnehelic gauge).
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.
FUSES:
F1 is the fuse to the inside of the circuit board controls. If F1 has blown there may have been an input
power overload or a short in the convection fan.
F2 fuse closest fuse to the outside edge of the circuit board controls. If fuse F2 has blown then there
was a electrical overload problem with one of the following parts: ignitor, auger motor, high limit switch,
or exhaust blower.
