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 hopper top behind the surround panel.
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 in the front of the unit under th ash pan.
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.
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”.
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.

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 120 volts, 60 hertz electrical
outlet and also must be accessible. If this power cord should become damaged, a replacement power
cord must be purchased from the manufacturer or a qualified ENVIRO dealer. Be careful that the electrical
cord is not trapped under the appliance and that it is clear of any hot surfaces or sharp edges. This unit’s
maximum power requirement is (4.1 Amps) 500 watts.
GLASS: Do not abuse the glass by striking or slamming the door. Do not attempt to operate the stove
with broken glass. The stove uses ceramic glass. Replacement glass must be purchased from an ENVIRO
dealer. Do not attempt to open the door and clean the glass while the unit is in operation or if glass is
hot. To clean the glass, use a soft cotton cloth and mild window cleaner, gas or wood stove glass cleaner,
or take a damp paper towel and dip into the fly ash. This is a very mild abrasive and will not damage the
glass.
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).

AUTOMATIC SAFETY FEATURES:
Your pellet Stove has the following safety features:
A) The stove will shut off when the fire goes out and the exhaust temperature drops below 120 °F
(49°C).
B) The stove has a high temperature safety switch. If the temperature on the hopper reaches 200 °F
(93 °C) the auger will automatically stop and you will get a #2 ash code, and the stove will shut off
when the exhaust temperature cools. If this happens call your local dealer to reset the 200 °F (93 °C)
high limit switch. FIND THE REASONS WHY THE UNIT OVERHEATED.
C) The unit is equipped with a vacuum switch to monitor the venting and the build up of ash in the burn
pot; if either becomes blocked the vacuum switch will turn off the auger and the stove will shut off.

MASONRY FIREPLACE INSTALLATION:
Installation
If installing the Empress with a skirt
the skirt must be installed before the
installation.
A non-combustible hearth pad must
cover combustible flooring underneath,
as well as 6” (150 mm) in front of the
heater and 6” (150 mm) to the side of
the heater.
1. Install the hearth pad.
2. Lock the fireplace damper in the
open position.
3. Install a positive flue connector at
the fireplace damper.
4. Set leveling leg to approximate
height.
5. Connect a Exhaust Starter Quick
Connect, straight or elbow, to the
exhaust pipe.
6. This fireplace insert must be installed
with a continuous chimney liner of 3”
or 4” diameter extending from the
fireplace insert to the top of the
chimney. The liner must conform
to type 3 requirements of CAN/ULC
S635.
Figure 5: Masonry fireplace installation without skirt.
When installing the insert into a masonry fireplace, DO NOT
remove any bricks or masonry, with the following exception:
masonry or steel, including the damper plate, may be
removed from the smoke shelf and adjacent damper frame,
if necessary, to accommodate a chimney liner. Do this only if
their removal will not weaken the structure of the fireplace
and chimney, and will not reduce protection for combustible
materials to less than that required by the national building
code. When installing the fireplace insert into a zero clearance
fireplace, DO NOT cut or modify any factory firebox parts.
