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: “Operation - Slider/Damper”
Cleaning: There will be some build up of flyash 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 annually or every two tons of pellets.
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 maximum power requirement is 700 watts (3.1 amp). The stove has a grounded electrical cord
and should be connected to a standard 220-240 volt, 50-Hz grounded electrical outlet. Make sure the
electrical cord is not trapped under the appliance and that it is clear of any hot surfaces or sharp edges.
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 in accordance with applicable local, state or federal codes.
TO PREVENT THE POSSIBILITY OF A FIRE, THIS APPLIANCE MUST BE PROPERLY
INSTALLED BY FOLLOWING THE INSTALLATION INSTRUCTIONS. 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 OFFICIALS TO OBTAIN A PERMIT AND ANY INFORMATION ON ANY
INSTALLATION RESTRICTIONS AND INSPECTION REQUIREMENTS FOR YOUR AREA.
An ENVIRO dealer will be happy to assist you.

Operating Instructions
optIonaL SLIDer/Damper InStaLLatIon:
SLIDer/Damper operatIon:
THE TUBE SCRAPER ROD:
Put the stainless steel rod through the hole in the heat exchanger, thread the rod into the scraper plate.
•On the low heat output settings, push the slider all the way in.
•On the high heat output pull the slider out or until a good fire is achieved. A good fire is in between a
fire with lazy flames black tipped flames and a forced fire (very quick, shorter flames). A good fire is the
most efficient and will have a bright and active flame.
•Hot magnetic reading 0.10 – 0.
This is used to regulate the airflow through the pellet stove.
1. Remove the slider rod (short rod with knob and nuts) and the two nuts from their package and open
the left side panel.
2. Remove the knob and outer nut from the knob. Push the rod through the hole in the slider. Place the
lock nut on the rod and tighten, leaving a 1/32” gap between the slider and one of the nuts.
3. Make sure the slider moves freely. Close the side panel and tighten screws after placing the rod
through the panel. Screw the knob onto the slider.

7
Operating Instructions
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” in diameter, or over 28 sq. inches 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.
DecIDIng Where to Locate your peLLet appLIance:
removIng your neW Stove from the paLLet:
To remove your new stove from its pallet, open the ash pan and remove the two (2) screws from inside
this area as shown. Also remove the two (2) screws on the back of the pedestal. Remove the unit from
the pallet and replace the ash pan.

8
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.
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. Vent terminal cannot be:
● less than 4 feet (1.2 m) below
● less than 4 feet (1.2 m) horizontally from, and
● less than 1 foot (305 mm) above doors, window openings, or gravity/ventilation air inlet into building
5. Distance from bottom termination and grade –12” (305 mm) 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. Distance from bottom of termination and public walkways is
7 feet (2.1 m) minimum.
6. Distance to combustible materials is 2 feet (610 mm). This includes adjacent buildings, fences, protruding parts
of the structure, roof overhang, plants, shrubs, etc.
7. 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 ofSherwood Industries Ltd, we grant no
guarantee against such incidents.
IT IS RECOMMENDED THAT YOUR PELLET STOVE BE INTALLED BY AN AUTHORIZED DEALER/INSTALLER.
NOTE: Measure clearance to the nearest edge of the exhaust hood
A- MINIMUM 4 feet (1.2m) below or beside any door or window that opens.
B- MINIMUM 1 foot (305 mm) above any door or window that opens.
C- MINIMUM 2 feet (610 mm) from any adjacent buildings.
D- MINIMUM 7 feet (2.1 m) above grade when adjacent to public walkways.
(NOTE) Vent may not terminate in a covered walkway or breezeway.
E- MINIMUM 2 feet (610 mm) above plants, grass or other combustible materials.
F- MINIMUM 3 feet (915 mm) from any forced air intake of other appliances.
G- MINIMUM 2 feet (610 mm) below any eave or roof overhangs.
H- MINIMUM 1 foot (305 mm) clearance to a combustible wall.

Installation
horIzontaL through WaLL InStaLLatIon:
The ENVIRO Alliance (EF3) can be vented by a couple of different methods.
1. NOTE: Use only listed type “PL” or “L” pellet venting products. Failure to use listed components may
cause damage or personal injury or death.
2. 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.
3. Install a non-combustible hearth pad underneath the unit extending 6 inches (15 cm) in
front of and to the sides.
4. Place the stove 15” (38.1 cm) away from the wall. If the stove is to be set on a hearth pad, set the
unit on it.
5. Locate the center of the exhaust pipe on the stove. Extend that line to the wall. Once you have
located the center point on the wall, use a hole saw to cut a 10” (25.4 cm) diameter hole for a 3” (7.6
cm) vent pipe or an 11” (27.9 cm) hole for a 4” (10.1 cm) vent pipe.
6. Install the wall thimble as per the instructions written on the thimble. Maintain an effective vapor
barrier
7. Install a 2’ or 3’ (61 or 92 cm) length of 3” (7.6 cm) or 4” (10.2 cm) listed type “PL” or “L” vent pipe
into the wall thimble. The pipe should install easily into the thimble.
8. Install the fresh air intake (see the section entitled FRESH AIR CONNECTIONS).
9. Connect the exhaust vent pipe to the exhaust pipe on the stove.
10. All Joints in the vent system shall be fastened with (3) three screws. Seal the connection with high
temperature silicone
11. Push the stove straight back, leaving a minimum of 1” (2.5 cm) clearance from the back of the stove
to the wall. Seal the vent pipe to the thimble with high temperature silicone.
12. The pipe must extend at least 12’ (30.5 cm) away from the building. If necessary, bring another
length 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.
13. 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 degree elbow can be used as termination. The elbow must be turned down to
prevent rain from entering.
NOTE: Some horizontal, through the wall installations may require a “T” and 4-5 feet (1.2-1.5 m) of
vertical pipe outside the building to help draft the stove. 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 back-pressure in the
exhaust, caused by the air flow around the house

1. Choose a stove location that is ideal. See the section Deciding Where to Locate Your Pellet
Appliance.
2. Place a non-combustible hearth pad where necessary.
3. Place the unit on the hearth pad and space it in a manner so when the pellet vent is installed
vertically, it will be 3” (76 mm) away from a combustible wall.
4. Locate the center of the fresh air intake pipe on the unit. Match that center with the same point
on the wall and cut a hole about 1 5/8” (41 mm) in diameter.
5. Install the fresh air intake pipe.
6. Install the tee with clean out.
7. Install the pellet vent upward from there. When you reach the ceiling make sure that the vent
goes through the ceiling firestop. Maintain a 3” (76 mm) distance to combustibles and keep attic
insulation away from the pipe.

mobILe home InStaLLatIon:
•Secure the heater to the floor using the two bolt holes supplied in the pedestal.
CAUTION: THE STUCTURAL INTEGRITY OF THE MANUFACTURED HOME FLOOR, WALL, AND
CEILING/ROOF MUST BE MAINTAINED.
•Ensure the unit is electrically grounded to the chassis of your home (permanently).
•Do not install in a room where people sleep.
•Outside fresh air is mandatory when installing into airtight homes or manufactured homes.
freSh-aIr connectIonS:
A Fresh-air intake is strongly recommended. Failure to install Intake air may result in improper
combustion as well as the unit smoking during power failures.
NOTE: Fresh air is mandatory on all units installed in “Mobile Homes” as well as in “Air
Tight” homes.
When connecting to an outside fresh-air source, do not use plastic, combustible pipe. Only 1 5/8”
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.

16
Troubleshooting
This toubleshooting is for both Timer Control and Circuit Board style Alliance. It will
be stated if the troubleshooting relates only to one model.
DO NOT:
Hold the ON / OFF BUTTON down for circuit board model or hold the start-up switch down for timer
control. This is a momentary contact switch and can be damaged if held down too long.
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 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 operate when hot.
3. The exhaust blower will not function normally.
4. The convection blower will not function normally.
5. Ignitor : The pellets will not light.
6. The auger motor does not function normally.
7. Control settings (heat level) have no effect on fire (Circuit Board).
8. The Dial-A-Fire has no effect on the fire (Timer Control).
8. The stove will not shut off.
9. The stove keeps going out.
*NOTE: All troubleshooting procedures should be carried out by qualified technicians or
installers.
1. The stove will not start.
General
Make sure the stove is plugged in and the wall outlet is supplying power.
Timer Control
 Push the Start-up switch. If the stove fails to start, unplug the unit and open the hinged side panels
(held tight with two screws).
 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 chassis ground wire).
 Check the continuity and placement of connections against the diagram in the back of this manual.
 Ensure that the connections to the (15) minute start-up timer are correct.
 Attempt to bypass the switch by inserting a jumper wire between the red and white wires that attach
to the switch. Plug the stove back in. If the stove starts, replace the switch.
 If this fails, replace the (15) minute start-up timer.
Circuit Board
 Push the ON /OFF button.
 If the Control Board has been placed in the ON /OFF thermostat mode, then turn the thermostat up
to call for heat.

17
Troubleshooting
 If the unit still does not start, contact your local service dealer for service.
2. The stove will not operate when hot.
General
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. (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 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).
Note: If the motor fails to reach a 0.10” w.c. reading, 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.
The unit may require cleaning. Contact your local dealer for service.
Timer Control
 Unplug the stove, open the left side panel. Jump the two brown leads that are attached to the 140°F
(60°C) temperature sensor. If the stove operates replace the 140°F (60°C) sensor.
Circuit Board
 The third red LED light in the heat level indicator light will flash if a fire is not detected, or if the fire
has gone out.
3. The exhaust motor will not function normally.
General
Open the left side access panel; check all connections against the wiring diagram.
Contact your local dealer for service.
Timer Control
 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.
 Apply 220 V directly to the exhaust blower. If the motor does not run, replace the blower.
If the motor runs, have your dealer check the harness.
4. The convection blower will not function normally.
Timer Control
 Check all the connections between the controller, switch, and the convection blower against the wiring
diagram.

18
Troubleshooting
 If the convection motor will not run, apply 220 V 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.
 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.
If the motor is still on high, re-connect the sensor and replace the convection fan controller.
Circuit Board
 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.
5. Ignitor- the pellets will not light.
Everything else in the stove operates but the ignitor will not light the pellets
Timer Control
 Check all the electrical connections on the 120°F (49°C) temperature sensor located on the exhaust
channel.
 Check the connections at the ignitor socket.
 Place a jumper wire between the two leads on the 120°F (49°C) temperature sensor. If the ignitor
works, replace the sensor.
 If the ignitor does not work, replace it.
Circuit Board
 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.
NOTE: The ignitor should be bright orange in color. If not, replace the ignitor.
6. The auger motor will not function normally.
General
Check for obstructions in the hopper system.
Call your local dealer for service.
Timer Control
 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.

19
 If the auger still does not work, then apply 220 V 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 1-2 V, 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 0.5wc”. 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 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 68K to approximately
850 K (±10%).Iif the range is not close, replace the potentiometer.
7. Control settings (Heat Level) have no effect on the fire (Circuit Board).
NOTE:
 If the system light is flashing, the Control Board has complete control of the unit. When the unit’s
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.
8.The dial-a-fire has no effect on the fire (Timer Control).
 Make sure all connections to the timer control module are secure.
 Perform a resistance test to the dial-a-fire potentiometer by placing the two test leads from a
multimeter into the leads of the potentiometer. The potentiometer should have a range of 68K to
approximately 850 K (± 10%).
Potentiometer Readings:
Full counter-clockwise (switched off) = open circuit, overload or infinite resistance
Low fire 800 K to 900 K
High fire 68 K to 82 K
9.The stove will not shut off.
Timer Control
 Check the connections to the 140°F (60°C) temperature sensor, start-up switch and the start-up timer
against the wiring diagram.
 Check the 140°F (60°C) temperature sensor by removing one of the brown wires from the sensor.
The unit should shut down right away as long as the start button was not pressed within 15 minutes of
this test. If the stove shuts down within 15 minutes, replace the 140°F (60°C) sensor. If the stove does
not shut down within 15 minutes, test the switch.
 To test the switch, the stove must be cold. Pull the plug, then plug the stove back in. If it fails to
start, replace the switch.
