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 inside of the ash pan cover.
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.
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: “
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.
3
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 115 volts (4.6 Amps), 60
hertz electrical outlet. Be careful that the electrical cord is not trapped under the appliance and that it is
clear of any hot surfaces or sharp edges and also must be accessible. If this power cord should become
damaged, a replacement power cord must be purchased from the manufacture or a qualified ENVIRO
dealer. This unit’s maximum power requirement is 520 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.
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 connection is optional. 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. 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).

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.

This unit does not require a full reline (in USA only) when installing into a masonry fireplace, however, it
is recommended to ensure proper drafting of the appliance.
IMPORTANT: Ensure the chimney and firebox are cleaned and free of all debris, including soot and ashes,
before proceeding with this installation. If it is not clean soot maybe blown into the room through the
unit’s blower. Ensure the fireplace and chimney have not deteriorated in any way. If there is any sign of
corrosion or damage in the chimney the unit can not be installed. This unit can be installing in a masonry
fireplace built to (UBC 37 or ULC S628 standards) or a factory built fireplace (built to UL 127 or ULC S610
standards).
1. If installing the Empress with a skirt, the skirt must be installed before the installation.
2. Install the hearth pad. The floor 6” (150 mm) in front of the unit and 6” (150 mm) to each side of the
unit must be protected with a non-combustible hearth pad.
3. The vent connector from the insert must extend a minimum of 18” above the chimney seal plate. The
chimney seal plate area must be sealed to prevent the exhaust from the chimney from coming back
into the fireplace and prevent air
from the fireplace from entering
the chimney which will affect
proper drafting of appliance.

must effectively seal the area to
prevent room air passage to the
chimney cavity of the fireplace.
A couple examples of Approved
Methods of Achieving a Positive
Flue Connection are:
a) Secure a seal-off plate (i.e.
22-gage sheet steel) in the
masonry fireplace throat using
masonry screws.
b) Pack non-combustible material
(i.e. rockwool) around the vent

Installation
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 41: Efficient Flame.
Taking a reading of vacuum pressure inside the firebox
with a magnehelic gauge can 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 placing a Magnahelic Pressure Gauge in the
firebox. The reading can be taken from the ⅛” (3 mm)
hole located in the front of the firebox under the door
(see Figure 42). The best settings are a reading of
approximately 0.10 inches of water column on the
high fire setting. Some fuels may require higher or
lower settings.
Figure 42: Hole for Pressure test with
Magnehelic Gauge.

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. 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.
Make sure the stove is plugged in and the wall outlet is supplying power..
If the Control Board has been placed in the ON /OFF thermostat mode, then turn the thermostat up to
call for heat.
Ensure the burn pot liner is correctly placed in the burn pot
Check the Heat Level Indicator. - If the # 2 light is flashing (see the # 2 light is flashing)
Check the fuse on the circuit board.
If the unit still does not start, contact your local service dealer for service.
2. The stove will not operate when hot.
Check 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.
Check the hopper for fuel.
Incorrect 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).
Combustion 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.
Check the Exhaust Blower voltage across the blower wires (>=114 V on #5 setting and >= 82 on #1
setting). – Replace the Circuit Board if the Voltage reading is less than 82 V. with a line voltage >115
V AC.
28
Troubleshooting
Check 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.
Poor Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove burning
or operational.
Exhaust 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.
Check the fuse on the circuit board.
3. The exhaust motor will not function normally.
Open the left side access panel; check all connections against the wiring diagram.
See “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.)
Pinch, break or blockage in Vacuum Hose - Check hose for pinch points or damage, replace or re-route
as required. Blow out Vacuum Hose
Blocked 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.
Blocked exhaust / venting system - Have stove and venting cleaned and inspected.
Severe 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.
Vacuum Switch failure - Bypass the vacuum switch, if this corrects the problem check for above
problems before replacing the Vacuum Switch.
Damage to gray wires between Circuit Board and Vacuum Switch - Inspect wires and connectors
Combustion 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 (>=114 V on #5 setting and >= 82 V on #1 setting). – Replace the
Circuit Board if the Voltage reading is less than 82 V. with a line voltage >114 V AC.
Check 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.
If 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**
Check the fuse on the circuit board.
29
Troubleshooting
6. The 200 °F ( 93 °C) high limit temperature sensor has tripped.
Reset 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 not
replace the blower? If yes, replace sensor (located on the left side of the firewall).
Check the fuse on the circuit board.
7. The convection blower will not function normally.
Clean all grill openings at the back and below unit .
Press 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.
Make sure the burn pot liner is up tight and square to the ignitor tube by pushing the burn pot back
against the ignitor tube.
Check to see if the exhaust blower is operating. If not, contact your local dealer for service.
Check 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.
NOTE: 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.
If there is no control of the Heat Level button make sure the thermostat is calling for heat.
Call 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.
Check to see that the Slider / Damper is in the correct position.
Turn the Heat Level up slightly (poor quality pellets will require slightly higher settings).
Set 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.
Adjust the Slider / Damper.
Check to see if the stove needs a more complete cleaning.
Turn the Heat Level up slightly (poor quality pellets will require slightly higher settings).
Did the power go out?
Contact your local Dealer for service.

Here is how our Warranty works
If you have any concerns with your Enviro product please contact the dealer where you purchased the replace or

Exclusions and Limitations:
1. This Warranty does not cover tarnish, discoloration or wear on the plating or paint.
2. This Warranty excludes wear and tear or breakage caused by cleaning, moving or service on log set.
3. A qualified installer must install this stove or fireplace. This Limited Warranty covers defects in materials and workmanship only if the
product has been installed in accordance with local building and fire codes; in their absence, refer to the owner’s manual. If the product
is damaged or broken as a result of any alteration, willful abuse, mishandling, accident, neglect, or misuse of the product, the Limited
Warranty does not apply.
4. The stove must be operated and maintained at all times in accordance with the instructions in the Owner’s Manual. If the unit shows signs
of neglect or misuse, it is not covered under the terms of this Warranty policy. Performance problems due to operator error will not be
covered by the Limited Warranty policy.
5. As this is a heating appliance some changes in colour of surface finishes may occur. This is not a flaw and as such is not covered under this
warranty.
38
Warranty
6. Some minor expansion, contraction, or movement of certain parts and resulting noise, is normal and not a defect and, therefore, is not
covered under this Limited Warranty.
7. Misuse includes over-firing. Over-firing this appliance can cause serious damage and will nullify the Limited Warranty.
8. The Limited Warranty will cover glass thermal breakage only and will not cover misuse of the stove glass, including but not limited to glass
that is struck, has surface contaminates or has had harsh or abrasive cleaners used on it.
9. This warranty does not cover products made or provided by other manufacturers and used in conjunction with the operation of this stove
without prior authorization from Sherwood Industries Ltd. The use of such products may nullify the Limited Warranty on this stove. If
unsure as to the extent of this Limited Warranty, contact your authorized Enviro dealer before installation.
10. Sherwood Industries Ltd. will not be responsible for inadequate performance caused by environmental conditions.
11. The Limited Warranty does not cover installation and operational related problems such as spillage caused by environmental conditions.
Environmental conditions include but are not limited to nearby trees, buildings, roof tops, wind, hills, mountains, inadequate venting or
ventilation, excessive offsets, negative air pressures or other influences caused by mechanical systems such as furnaces, fans, clothes
dryers etc.

c) Any damage to the unit, combustion chamber or other components due to water, or weather damage which is the result of, but not

air or high humidity is not covered by the Limited Warranty.
13. Exclusions to the Limited Warranty include: injury, loss of use, damage, failure to function due to accident, negligence, misuse, improper
installation, alteration or adjustment of the manufacturer’s settings of components, lack of proper and regular maintenance, alteration, or
act of God.

exterior paint discoloration or chipping, worn gaskets, etc.

17. Damage to plated surfaces caused by fingerprints, scratches, melted items, or other external scores and residues left on the plated
surfaces from the use of abrasive cleaners or polishes is not covered in this warranty.
18. The Limited Warranty does not cover tarnish, discoloration or wear on the plated surfaces.
19. The paint on the Metal Brick Liner may peel. This is due to the extreme conditions applied to the paint during normal usage. It is not a
flaw and is not covered under warranty.
20. Sherwood Industries Ltd. is free of liability for any damages caused by the fireplace or stove, as well as inconvenience expenses and
materials. The Limited Warranty does not cover incidental or consequential damages.
21. The Limited Warranty does not cover any loss or damage incurred by the use or removal of any component or apparatus to or from the
Enviro fireplace or stove without the express written permission of Sherwood Industries Ltd. and bearing a Sherwood Industries Ltd. label
of approval.
22. Any statement or representation of Enviro products and their performance contained in Enviro advertising, packaging literature, or printed
material is not part of the Limited Warranty.
23. The Limited Warranty is automatically voided if the fireplace or stove’s serial number has been removed or altered in any way. If the stove
is used for commercial purposes, it is excluded from the Limited Warranty.
24. No dealer, distributor, or similar person has the authority to represent or warrant Enviro products beyond the terms contained within the
Limited Warranty. Sherwood Industries Ltd. assumes no liability for such warranties or representations.
25. Sherwood Industries Ltd. will not cover the cost of the removal or re-installation of the stove, hearth, facing, mantels, venting or other
components.
26. Labour to replace or repair items under this Limited Warranty will be covered per our warranty service fee reimbursement schedule.

In the event of in-home repair work, the customer will pay any in-home travel fees or service charges required by the Authorized Dealer.
28. At no time will Sherwood Industries Ltd. be liable for any consequential damages which exceed the purchase price of the unit. Sherwood

upgrades will not be performed).
29. This Limited Warranty is applicable only to the original purchaser and it is non-transferable.
30. This warranty only covers Enviro products that are purchased through an authorized Enviro dealer.
31. If for any reason any section of the Limited Warranty is declared invalid, the balance of the warranty remains in effect and all other
clauses shall remain in effect.
32. The Limited Warranty is the only warranty supplied by Sherwood Industries Ltd., the manufacturer of the stove. All other warranties,
whether express or implied, are hereby expressly disclaimed and purchaser’s recourse is expressly limited to the Limited Warranty.

improper usage, operation, installation, servicing or maintenance of this stove.
