Introduction
PELLET QUALITY:
Pellet quality is important, please read the following:
Your enviro pellet stove has been designed to burn wood pellets only. Do not use any other
type of fuel, as this will void any warranties stated in this manual.
The performance of your pellet stove is greatly affected by the type and quality of wood
pellets being burned. As the heat output of various quality wood pellets differs, so will the
performance and heat output of the pellet stove.
CAUTION: It is important to select and use only pellets that are dry and free of dirt or any impurities
such as high salt content. Dirty fuel will adversely affect the operation and performance of the unit
and will void the warranty. The Pellet Fuel Industries (P.F.I.) has established standards for wood pellet
manufacturers. We recommend the use of pellets that meet or exceed these standards. Ask your dealer
for a recommended pellet type.
P.F.I. PELLET STANDARDS:
Fines (fine particles)......1% maximum through a 1/8” screen
Bulk Density..................40 pound per cubic foot minimum
Size..............................1⁄4” to 5/16” diameter 1⁄2 – 11⁄2” long maximum
Ash Content..................1% maximum (Premium grade)
..................3% maximum (Standard grade)
Moisture Content...........8% maximum
Heat Content.................approximately 8200 Btu per pound minimum
ASH: The ash content of the fuel and operation of your stove will directly determine the frequency of
cleaning. The use of high ash fuels may result in the stove needing to be cleaned daily. A low ash fuel
may allow longer intervals between cleaning.
CLINKERING: [clinkers are silica (sand) or other impurities in the fuel that will form a hard mass during
the burning process]. This hard mass will block the air flow through the Burn Pot Liner and affect the
performance of the stove. Any fuel, even approved types, may tend to clinker. Check the Burn-Pot Liner
daily to ensure that the holes are not blocked with clinkers. If they become blocked, remove the liner
(when the unit is cold) and clean/scrape the clinkers out. Clean the holes with a small pointed object if
required. Refer to the section Routine Cleaning and Maintenance.
PELLET FEED RATES: Due to different fuel densities and sizes, pellet feed rates may vary. This may
require an adjustment to the slider damper setting or to the auger feed trim setting on low.
Since Sherwood Industries Ltd. has no control over the quality of pellets that you use, we assume no
liability for your choice in wood pellets.
Store pellets at least 36” (1 m) away from the pellet stove.
RATING LABEL LOCATION:
Freestanding: The rating label is located on the inside of the hopper lid.
Insert: The rating label is located on the hopper cover.

Introduction
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.
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.
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.

Introduction
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 floor on the ground, 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.
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 (3.9 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. The EF2’s maximum power requirement is 450 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.
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.
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).

Operating Instructions
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 the stove will shut down when the exhaust temperature
cools. If this happens, call your local dealer to reset the 200°F (93°C) high limit switch. ALSO FIND
THE REASONS WHY THE UNIT OVERHEATED.
C. The unit has a convection fan control over-ride. This function causes the convection fan to reach its full
speed when the temperature at the back of the firebox reaches 160°F (71°C). This is a normal safety
feature of your unit. To compensate for the fan cycling action that may occur, turn up the blower
control proportionately to the heat output.
D. If the power goes out, the unit will stop running. When the power comes back on, the stove will not
restart unless the exhaust temperature is still above 120°F (49 °C).
SLIDER/DAMPER SETTING:
This is used to regulate the airflow through the pellet stove. A Qualified Service
Technician or Installer should mark the slider rod in the current settings.
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).
If the fire should happen to go out and the Dial-A-Fire has been set on the lowest
setting, the Slider Damper should be pushed in slightly, decreasing the air in the
firebox or the Dial-A-Fire can be turned up slightly.
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,
Figure 1: Slider /
active flame with no black tips then the air is
damper positions.
set for proper operation, refer to Figure 2.
Figure 2: 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 best settings are a reading of 0.12 to 0.13 inches of water column (30 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 door and behind the magnetic ash lip.

Operating Instructions
OPERATING YOUR PELLET STOVE:
1. Check and fill hopper with pellets.
2. Make sure unit is plugged into a working outlet.
3. Switch the power on by pushing the ROCKER SWITCH to the
MANUAL position.
4. Turn KNOB B to the 12 o’clock position. (Lower grade
pellets may need a higher setting on the feed rate).
NOTE: Unit will take longer to light if the hopper has been
completely emptied or is the first fire up.
5. Approximately fifteen (15) minutes after the fire was lit, the
GREEN LIGHT should come on. When the GREEN LIGHT
comes on, push the ROCKER SWITCH to the AUTO
position. Now the stove will shut-off automatically if the fire
goes out.
6. Wait until the fire is established, then turn KNOB B to the
desired heat output. The stove may not be able to burn in
the BLUE ZONE if poor quality wood pellets are being used.
Adjust the slider-damper to the appropriate setting (see
“SLIDER/DAMPER SETTING” section.

Figure 3: Dial-A-Fire control panel.
KNOB “A”: Fan Controller. By adjusting the knob you will vary the rate of airflow into the room by varying
the speed of the convection blower. When you first start the stove, it should be placed in the “OFF”
position in order to heat the unit as quickly as possible. Once the room has come up to temperature, the
control may be set to a comfortable level. *Note: The convection blower may cycle to high automatically
depending on the setting of KNOBS A and B. This is a normal safety feature of the unit.
KNOB “B”: Dia-A-Fire Heat Output Knob. This knob controls the amount of heat output. The dial has a
scale with the blue zone representing the coolest setting of the stove, and the red zone representing
the hottest setting. The scale on knob “B” represents a range, not exact at times or fuel quantities.
Wood pellets of differing quality may affect the performance of the stove. If the stove has trouble
operating at either end of its range, turn the heat output knob back slightly.
TURNING YOUR PELLET STOVE OFF:
The AUTO/MANUAL SWITCH must be in the AUTO position during operation. To turn the stove off, simply
turn the HEAT OUTPUT knob (KNOB B) counter-clockwise until the knob clicks to the “OFF” position. This will stop
the feed of pellets. The blowers will continue to run and cool the stove.
SPECIAL NOTES:
If the stove is left in the manual mode after the green light comes on, the auger will continue to feed pellets. Pellets
may over flow the burn-pot after the fire goes out and also re-light.
The scale on KNOB B represents a range, not exact times. Wood pellets of differing quality
may effect the performance and/or the heat output of the stove. If the stove has trouble
operating at the end of its range, adjust the heat output knob back slightly.

Routine Cleaning and Maintenance
NOTE: Do not use abrasive cleaners to clean the surface or any part of the stove.
The following should be inspected periodically to ensure that the appliance is operating at its optimum
and giving you excellent heat value:
TOOLS REQUIRED TO CLEAN UNIT
• Torx T-20 Screwdriver
2-3 Days / Weekly
Biannually or 2 Tons of Fuel
• 5/16” Wrench or Socket,
Burn Pot and Liner
Exhaust Vent
• Brush,
Ash Pan
Fresh air Intake Tube
• Soft Cloth
Inside Firebox
Blower Mechanisms
• Vacuum with fine filter bag
Door Glass
Heat exchanger tubes
Heat exchanger tubes
Behind firebox liners
The following list of components should be
Ash pan & Door gaskets All Hinges
inspected and maintained routinely to ensure
Door Latch
Post Season Clean-up
that the appliance is operating at its optimum
and giving you excellent heat value:
BURN POT AND LINER (2-3 days)
This is the ‘pot’ where the pellets are burned. The burn pot and liner should be inspected every two to
three days, to ensure proper air flow through the liner. Failure to keep the liner clean may cause
a build up of fuel past the burn pot liner and up the drop tube. This will cause the auger to
jam and may result in pellets burning in the drop tube and hopper.
Ensure the unit is cold before cleaning. To remove the burn pot and burn pot liner, open the door using
the door handle provided, located on the left-hand side of the stove. Swing the door open. Lift the
liner from the burn pot. Lift the burn pot from the firebox by gently lifting the front of the burn pot up
first, then sliding the assembly from the air intake tube and the ignitor cartridge. Using a metal scraper,
remove material that has accumulated or is clogging the liner’s holes. Then dispose of the scrapped ashes
from the liner and from inside the burn pot. Place the burn pot back into the stove, making sure that the
pipes are properly inserted into the burn pot and the front tabs are placed in the firebox. Place the liner
back into the burn-pot making sure that the ignitor hole in the liner is aligned with the ignitor tube. Push
the liner up against the ignitor tube.
● If, after long periods of burning, the fire continually
builds up and overflows the burn pot or there is a build up
of clinkers, this is an indication that the pellet fuel quality
is poor or the stove may need cleaning. Check the stove
for ash build up (clean if required) and adjust the slider /
damper to produce the proper clean combustion.

INSIDE FIREBOX (2-3 days)
For bi-weekly clean out, ash may be removed from behind the steel plates by rotating the circular cover
to allow vacuuming behind the plates.
ASH PAN AND DOOR GASKETS (weekly)
After extended use the gasket may come loose. To repair or replace this, glue the gasket on, using hightemperature fiberglass gasket glue available from your local ENVIRO dealer. This is important to maintain
an airtight assembly.

Routine Cleaning and Maintenance
ASH PAN (2-3 days)
Monitor the ash level every week. Remember that different pellet fuels will have different ash contents.
Ash content is a good indication of fuel efficiency and quality. Dump the ashes into a metal container
stored away from combustibles. Refer to “Warnings and Recommendations” for disposal of ashes. DO
NOT PLACE UNBURNED OR RAW PELLET FUEL IN ASH PAN.
Vacuum the ash pan and inside the pedestal. CAUTION: BECAUSE THE FLY ASH IS VERY FINE, THE USE
OF A FINE FILTER VACUUM BAG WILL BE REQUIRED TO PREVENT ASH FROM BEING BLOWN BACK
INTO THE ROOM. Please pay special attention that there are no hot ashes in the firebox or there could
be a possibility of a fire hazard inside the vacuum cleaner. Place all hot ashes into a non-combustible
container.
FREESTANDING ASH PAN:
The EF2 pellet stove freestanding’s ash pan is located under the burner, in the pedestal, and has a
latching mechanism to secure it. To remove the ash pan, unlock the latch on the ash pan and then
pull the pan out.
FIREPLACE INSERT AND BUILT-IN HEATER ASH PAN:
The EF2 pellet stove insert’s ash pan is located behind the lower grill.
Heat exchange
tube cleaner rod
HEAT EXCHANGER TUBES (2-3 days)
The handle for the heat exchanger cleaning rod is pointed out in
Figure 5. This handle is to be pulled back and forth a few times
(ONLY WHEN THE UNIT IS COLD) in order to clean away any
fly ash that may have collected on the heat exchanger tubes. As
different types of pellets produce different amounts of ash, cleaning
of the tubes should be done on a regular basis to enable the unit to
run efficiently.
FRESH AIR INTAKE (season)
Inspect periodically to be sure that it is not clogged with any foreign
materials.
Figure 5: EF2 Heat exchanger rod.
EXHAUST PASSAGES (season)
For bi-weekly clean out, ash may be removed from behind the steel plates by rotating the circular covers
located behind the right and left side panels. Loosen the screw on the disks and open, this will allow
vacuuming behind the firebox liner’s plates.
Removal of the firebox backing for bi-annual cleaning:
• Remove the top baffle.
• Lubricate and then remove the seven (7) screws that hold the brick liner in place. Tilt the top of the
brick panel towards the firebox opening and remove from the firebox
• Remove the top rod by first removing the screw that holds it in place, then slide the rod sideways
• Pull the side panels into the center of the firebox, then out
• Pull the center panel out.
• Clean and vacuum all passages thoroughly.
9
Routine Cleaning and Maintenance
Installation of firebox backing:
• Install the side panels in place. Insert center panel, hold the panels in place
• Install the top rod by sliding it into one side panel then across into the other panel. Screw rod in
place.
• Re-install steel brick liner and screw in place.
• Replace top baffle
EXHAUST VENT (season)
The products of combustion will contain small particles of flyash. The flyash will collect in the exhaust
venting system and restrict the flow of the flue gases. Incomplete combustion, such as occurs during
startup, shutdown, or incorrect operation of the room heater will lead to some soot formation which will
collect in the exhaust venting system. The exhaust venting system should be inspected at least once
every year or after two tons of pellets to determine if cleaning is necessary. We recommend contacting
your dealer for professional cleaning. To remove dust from the vent pipe, tap lightly on the pipe to
dislodge any loose ash. Open the bottom of the “T” to dump the ash, then vacuum as much of the ash
out of the vent pipe as possible.
BLOWER MECHANISMS (season)
Unplug the stove then open the right and left side panels to access the two blowers. Vacuum all dust
from motors. Only the convection blower motor (on the right side of the stove) will require lubrication.
The convection motor has two lubrication holes on it. Use two drops of SAE 20 light oil to lubricate every
six (6) months. Excess oil may damage the motor. The exhaust blower’s motor has sealed bearings, DO
NOT lubricate this motor.
DOOR GLASS (It is recommended that your dealer replace the glass if broken.)
The door glass is made of 5 mm thick, high temperature PYROCERAMIC. To replace the glass, unscrew
and remove the four glass retainers. Remove the glass and any broken pieces. High temperature
fiberglass tape should be used around the glass. Replace the glass, center the glass assembly in the
frame, then screw the glass retainers back to the frame. The use of substitute materials is prohibited use
only part EF-061.
POST SEASON CLEAN-UP
Once you are finished using the pellet appliance for the season, unplug the stove for added electrical
protection. It is very important that the stove be cleaned and serviced as stated above.
CLEANING PLATED SURFACES
Please clean all fingerprints off of all plated parts, with denatured alcohol on a soft cloth, before firing the
unit each time. Fingerprints, etc. can become permanently etched into the plating if not removed before
operating the pellet heater.
BRICK PANEL
The paint on the steel brick panel may peel. This is due to extreme conditions applied to the paint and is
in no way covered by warranty.
10
Installation
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:
To remove your new stove from its pallet, open the left and right side panels. To open the side panels
remove the ash pan cover from the magnets located below the door. Remove the two (2) T-20 screws
located at the bottom corners of the left and right side panels. Remove the two (2) T-20 screws located
between the hopper side rails and the side panels at the front edge of the side panel.
There are two (2) wood screws that are holding the bottom of the stove to the pallet. Remove the screws.
Close the side panels. See “PEDESTAL INSTALLATION” to install the pedestal.

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
OUTSIDE FRESH-AIR CONNECTION:
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 15⁄8” minimum (42 mm) 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.

HORIZONTAL EXHAUST THROUGH WALL INSTALLATION - FREESTANDING:
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 shall conform to CAN/CSA-B365 Installation Code for Solid-Fuel-Burning Appliances and
Equipment. Only use venting of L or PL type with an inside diameter of 3 or 4 inches (7.6 or 10.1 cm).
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).

of pipe (PL type) 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:
• 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 24 is the recommended installation set up.
Figure 25 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

Figure 30: Masonry fireplace installation.
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. If the fireplace insert does not fit into a zero clearance fireplace, we recommend you use
an ENVIRO freestanding model and install as a hearth mounted unit. Install a 3” (76 mm) flex pipe from
the stove to the top of the chimney (see “HEARTH MOUNT INSTALLATION - FREESTANDING:”).

26
Troubleshooting
DO NOT:
w Switch the stove On and OFF rapidly. This may cause current spikes, which could shorten the life of the
electrical components.
w 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.
w Remove any screws in the firebox without first lubricating them with penetrating oil.
WHAT TO DO IF:
1. The stove will not start.
2. The stove will not light
3. The stove will not function in the “AUTO” mode when hot.
4. The exhaust blower will not function normally.
5. The convection blower will not function normally.
6. Everything else in the stove operates but the ignitor will not light the pellets
7. The auger motor does not function normally.
8. The Dial-A-Fire has no effect on the fire.
9. The stove will not shut off.
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.
w Make sure the stove is plugged in and the wall outlet is supplying power.
w Push the AUTO/MANUAL switch to MANUAL. If the stove fails to start, unplug the unit and open the
hinged side panels (held tight with (2) two screws).
w With the stove unplugged, examine all connections. Make sure they are firmly connected and that
there are no exposed wires touching the stove (except the green chassis ground wire).
w Check the continuity and placement of connections against the Wiring Diagram in this manual.
w Attempt to bypass the switch by inserting a jumper wire between the dual black wires (middle of the
switch) and the single grey wire (left side of the stove) that attach to the back of the switch. Plug the
stove back in. If the stove starts, replace the switch.
2. The stove will not light
w Check the ignitor by removing the burn pot liner when the unit is cold.
w Push the AUTO/MANUAL switch to MANUAL.
w Observe the ignitor in the small tube to see if it glows within three (3) minutes then return the switch
to the “AUTO” position.
w If the ignitor does not come on, open the right hand side panel, remove the convection blower (held
in by two (2) bolts) and check connections of the harness then by-pass the 120°F (49°C) (N/C)
temperature sensor.
w Push switch to manual to see if the ignitor will heat up.
w If the ignitor fails to come on, have your dealer or a qualified service technician replace the ignitor.
w If the ignitor comes on when the 120°F (49°C) is by-passed, replace the 120°F (49°C) (N/C)
sensor.
27
Troubleshooting
3. The stove will not function in the “AUTO” mode when hot.
w If the unit fails to operate, by-pass the auto side of the switch by inserting a jumper wire between the
dual black wires and the dual brown wires located on the back of the switch. Plug the stove back in.
If the stove operates, replace the switch.
w Check the hopper for fuel.
w 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. (NOTE: Unit may require a change to the vent
system or installation of fresh air to correct Air to Fuel ratio problems).
w 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?
w 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 0.10” W.C. on low fire).
Note: If the motor fails to reach a 0.10” W.C. reading, then replace the Combustion Blower.
w Poor Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove burning
or operational.
w 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.
w The unit may require cleaning. Contact your local dealer for service.
4. The exhaust motor will not function normally.
w Open the left side access panel; check all connections against the wiring diagram.
w If all the connections are verified and the exhaust blower does not function at all, tap lightly on the
exhaust blower’s motor end cap, this may loosen a tight motor.
w Apply 115 V AC directly to the exhaust blower. If the motor does not run, replace the blower.
w If the motor runs, have your dealer check the harness.
w Contact your local dealer for service.
5. The convection blower will not function normally.
w Check all the connections between the controller, switch, and the convection blower against the wiring
diagram.
w If the convection motor will not run, apply 115 V AC to the motor directly. If the motor runs, replace
the fan controller. If the motor does not run, the convection blower has failed. Replace the blower.
w If the convection blower runs on high at all times (no control with the fan controller), check the
connections from the 160°F (71°C) sensor (located on the upper left side of the firewall) and
convection fan controller to the blower. Disconnect one of the wires from the sensor; if control of the
convection blower returns to the fan controller, replace the sensor.
w If the motor is still on high, re-connect the sensor and replace the convection fan controller.
28
Troubleshooting
6. Everything else in the stove operates but the ignitor will not light the pellets.
w Check the burn pot liner placement, the burn pot liner should be tight against the ignitor.
w Check all the electrical connections on the 120°F (49°C) temperature sensor located on the exhaust
channel.
w Check the connections at the ignitor socket.
w Place a jumper wire between the two leads on the 120°F (49°C) temperature sensor. If the ignitor
works, replace the sensor.
w If the ignitor does not work, replace it.
NOTE: The ignitor should be bright orange in color. If not, replace the ignitor.

Check for obstructions in the hopper system.
Call your local dealer for service.
Make sure the exhaust blower is operating.
Make sure the dial-a-fire is turned on.
Unplug the stove and open the side and back panels.
Check all the connections to the auger motor, auger dial-a-fire, vacuum sensor, 200°F (93°C)
temperature sensor and the timing control module against the wiring diagram in this manual.
Check the condition of the vacuum hose (located on the left side of the stove). It should not be
cracked or torn and should be installed on the top air inlet tube on the vacuum sensor.
Check the manual reset button on the 200°F (93°C) temperature sensor. If this sensor has been
tripped, check for the cause of the over-heating before pushing the red button in. Check auger for
movement.
If the auger still does not work, then apply 115 V AC directly to the auger motor. If the auger motor
does not work, replace it.
By pass the 200°F (93°C) temperature sensor with a jumper wire; check the auger. If the auger works,
replace the sensor.
Check the voltage across the load pins of the timing module. It should be around 1 V to 2 V AC,
cycling to line voltage during an auger pulse. If not, replace the timing control module.
Check the vacuum sensor by placing a jumper wire between the blue wire and the black wire that
are attached to the sensor. If the auger works, test to see if the exhaust blower is producing enough
vacuum.
To test the exhaust vacuum, place a magnehelic gauge in the sensor end of the vacuum tube. It
should read 0.5” W.C. If the reading is good, replace the vacuum sensor.
If the auger motor still does not work, then attempt to by-pass the auger dial-a-fire control by
removing the leads from the timing control module’s second delay pins and placing a jumper wire
across the pins. If the auger now cycles very quickly, test the dial-a-fire potentiometer. If the auger
did not cycle, replace the timing control module.
To test the dial-a-fire potentiometer, the potentiometer should have a range of 68KΩ to approximately
850 KΩ (± 10%). If the range is not close, replace the potentiometer.
29
Troubleshooting
8. The dial-a-fire has no effect on the fire.
w Make sure all connections to the timer control module are secure.
w Perform a resistance test to the dial-a-fire potentiometer by placing the two (2) test leads from a
multimeter into the leads of the potentiometer. The potentiometer should have a range of 68KΩ to
approximately 850 KΩ (± 10%).
Potentiometer Readings:
Full counter-clockwise (switched off) = open circuit, overload or infinite resistance
Low fire ...............................800 KΩ to 900 KΩ
High fire ..............................68 KΩ to 82 KΩ
If the range is not close or does not vary then replace the potentiometer.
9. The stove will not shut off.
w Make sure the AUTO/MANUAL switch is in the AUTO position.
w Check the connections to the 120°F (49°C) temperature sensor and AUTO/MANUAL switch against the
wiring diagram.
w Check the 120°F (49°C) temperature sensor by removing one of the brown wires from the sensor.
The unit should shut down right away as long as the switch is in the AUTO position. If the stove shuts
down, replace the 120°F (49°C) sensor. If the stove does not shut down, test the switch.
w To test the switch, the stove must be cold. With one of the brown wires removed from the 120°F
(49°C) temperature sensor, remove the grey wire from the switch, the stove should shut down. If this
is the result then replace the AUTO/MANUAL switch.
w If the stove still does not shut off, replace the wiring harness.
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.
w Check to see that the Slider / Damper is in the correct position.
w Turn the Dial-a-Fire up slightly (poor quality pellets will require slightly higher settings).
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.
w Adjust the Slider / Damper.
w Check to see if the stove needs a more complete cleaning.
w Did the power go out?
w Contact your local Dealer for service.
w Turn the Dial-a-Fire up slightly (poor quality pellets will require slightly higher settings).
If the stove goes out and there are no pellets in the liner, the auger is stopping.
w See “The auger motor will not function normally” and “The exhaust blower will not function
normally.”

tear, or exterior paint discoloration or chipping, worn gaskets, etc.
16. The Limited Warranty does not include damage to the unit caused by abuse, improper installation, or modification of the unit.
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. Labour rates are set per component and as such total labour costs may not be covered.
27. Sherwood Industries Ltd. is not liable for freight or labour on any stove replaced in-field and is not liable for travel costs for
service work. 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 Industries Ltd. has no obligation to enhance or modify any stove once manufactured (example: as a stove evolves,
field modifications or 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.
33. Sherwood Industries Ltd. and its employees or representatives will not assume any damages, either directly or indirectly, caused
by improper usage, operation, installation, servicing or maintenance of this stove.
34. Sherwood Industries Ltd. reserves the right to make changes without notice. Please complete and mail the warranty registration
card and have the installer fill in the installation data sheet in the back of the manual for warranty and future reference.
35. Sherwood Industries Ltd. is responsible for stocking parts for a maximum of seven (7) years after discontinuing the manufacture
or incorporation of the item into its products. An exception to this would be if an OEM supplier is not able to supply a part.
