Introduction
* This manual is designed for the technician in conjunction with the owner’s manual. *
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: “S
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.
LIDER/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 115 volts (4.7 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 540 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

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.

OPTIONAL HEARTH PAD INSTALLATION:
This unit can be installed on a combustible floor (e.g. linoleum, hardwood flooring) when the Optional
Hearth Pad is installed. If this unit is to be installed onto a carpeted surface, a solid pad must be used
underneath the Optional Hearth Pad for stability.
Carefully place the the pellet appliance on its back, on the pallet (allow the exhaust tube to fit thru an
opening in the pallet). Align the holes in the hearth pad and the unit and install the four (4) screws
provided. Stand the unit back up. Adjust the leveling legs to below the Hearth Pad, to support the weight
of the unit.
When moving the unit - be careful not to damage the floor or the Hearth Pad.
THERMOSTAT INSTALLATION:
1. Install the wall thermostat in a location that is not to close too the unit but will effectively heat the
desired area.
Figure 7: Thermostat wire placement.
Figure 6: Installing Hearth Pad Pedestal onto EF5.
2. Install a 12 or 24 Volt Thermostat using an 18 x 2
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 heating load is not
great enough when the stove is on low, the high limit

inlet to any appliance.
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.
Figure 8: Use in conjunction with Table 1 for allowable exterior vent termination
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.
