Safety Warnings & Recommendations

* This manual is designed for the technician in conjunction with the owner’s manual. *

Please read this entire Technical Manual before installing or operating your Enviro Pellet Stove.
Failure to follow these instructions may result in property damage, bodily injury or even death.
Any unauthorized modification of the appliance or use of replacement parts not recommended
by the manufacturer is prohibited. All national and local regulations and shall be complied with
when operating this appliance.

Caution: Do not connect to any air distribution duct or system.

Warning: Never place wood, paper, furniture, drapes or other combustible materials within 48” (122cm)

of the front of the unit, 12” (30.5cm) from each side, and 4” (10cm) from the back of the unit. Do not let
children or pets touch it when it is hot.

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.

FIRE EXTINGUISHER AND SMOKE DETECTION: All homes with a pellet burning stove should have at
least one fire extinguisher in a central location known to all in the household. Smoke detectors should be
installed and maintained in the room containing the stove. If it sounds the alarm, correct the cause but do
not deactivate. You may choose to relocate the smoke detection devise within the room; DO NOT REMOVE
THE SMOKE DETECTOR FROM THE ROOM.

CHIMNEY OR RUN AWAY FIRE: Call local fire department (or dial 911). Close the draft fully. Extinguish
the fire in the burn pot liner with a cup of water and close the door. Examine the flue pipes, chimney, attic,
and roof of the house, to see if any part has become hot enough to catch fire. If necessary, spray with fire
extinguisher or water from the garden hose. IMPORTANT: Do not operate the stove again until you are
certain the chimney and its lining have not been damaged.

OPERATION: The door and ash drawer must be kept closed when the unit is in operation to prevent
fume spillage and for proper and safe operation of the pellet stove. Also ensure all gaskets on the door
are checked and replaced when necessary. Unit hot while in operation. Keep children, clothing and

furniture away. Contact may cause skin burns.

CAUTION: When operating during adverse weather, if the unit exhibits dramatic changes in combustion

stop using the unit immediately.

FUEL: This stove is designed and approved to only burn wood pellets of any quality, corn, wheat, barley,
and grass. 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. Do not burn garbage or flammable fluids such as gasoline, naptha or engine oil.

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.
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.

The appliance, flue gas connector and the chimney flue require regular cleaning. Check them for blockage
prior to re-lighting after a prolonged shut down period.

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 surface, 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 thoroughly cooled.

Safety Warnings & Recommendations

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 110-120 volts (4.2 Amps), 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 504 watts.

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.

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.

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: Contact your local building or fire official to obtain a permit and any information on
installation restrictions and inspection requirements for your area.

Be sure to maintain the structural integrity of your home when passing a vent through walls, ceilings, or
roofs, and all construction meets local building codes. It is recommended that the unit be secured into its
position in order to avoid any displacement. This appliance must be installed on a floor with an adequate
load bearing capacity, if existing construction doesn’t meet load capacity, suitable measures (e.g. load
distributing plate) must be taken to achieve it.

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: This unit uses large quantities of air for combustion; outside Fresh Air connection is strongly
recommended. Fresh Air 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. NOTE:
Extractor fans when operating in the same room or space as the appliance may cause problems. Limited air
for combustion may result in poor performance, smoking and other side effects of poor combustion.

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.

Soot or creosote may accumulate when the stove is operated under incorrect conditions such as an rich
burn (black tipped, lazy orange flames).

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.

deciding Where to locate your pellet appliance:

1. Do not install the stove in a bedroom or room where people sleep in.

2. Locate the stove in a large and open room that is centrally located in the house. This will optimize

heat circulation.

3. Check clearances to combustibles and for the least amount of interference to house framing, plumbing,

wiring, etc.

4. You can vent the stove with approved pipe through an exterior wall behind the unit or pass it through

the ceiling and roof. The stove can connect 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).

5. This unit must not be installed directly onto carpet. If it is to be installed on a carpeted area, a solid

surface (wood, metal or approved hearth pad) must be installed between the unit and the carpet.

6. This unit uses large quantities of air for combustion; outside Fresh Air connection is strongly

recommended. Fresh Air must be connected to all units installed in Mobile and “Air Tight Homes”
(R2000) or where required by local codes.

7. Do not obtain combustion air from an attic, garage or any unventilated space. Combustion air may be

obtained from a ventilated crawlspace.

8. The power cord is 8 feet (2.43 m) long and may require a grounded extension cord to reach the

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:

This Heater must have adequate air for proper combustion in the room that it is installed.

A Fresh-air intake is strongly recommended for all installations. Failure to install intake air may

result in improper combustion as well as the unit smoking
during power failures.

The inlet to the intake must be below and a minimum of 12”
(30cm) away from the unit exhaust outlet.

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 3” minimum (76 mm) ID (inside
diameter) steel, aluminum or copper pipe or ducting should
be used. The inlet must have a rodent screen installed. It is
recommended, when you are installing a fresh air system, to
keep the number of bends in the pipe to a minimum.

Installation

horizontal exhauSt through Wall inStallation:

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 must conform to CAN/CSA-B365 Installation Code for Solid-Fuel-Burning Appliances and
Equipment and with all local regulations, including those referring to regional and national. Only use
venting of L or PL type or corn certified venting if corn will be burned as a fuel with an inside diameter
of 4 inches (100 mm).

1. Place the appliance 15” (37.5 cm) away from the wall. If the stove is to be set on a hearth pad, set
the unit on it.

2. 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, refer to pellet vent manufacturer installation instructions for correct hole
size and clearance to combustibles.

3. Install the wall thimble as per the instructions written on the thimble. Maintain an effective vapour
barrier in accordance with local building codes.

4. Install a length of vent pipe into the wall thimble. Try not to have joints inside the thimble.
The pipe should install easily into the thimble.

5. Connect the exhaust vent pipe to the exhaust pipe on the stove. Seal the connection with high
temperature silicone.

6. Install the fresh air intake (see Outside Fresh Air COnneCtiOn).

7. Push the stove straight back, leaving a minimum of 4” (10 cm) clearance from the back of the stove
to the wall. Seal the vent pipe to the thimble with high temperature silicone.

8. The pipe must extend at least 12” (30 cm) away from the building. If necessary, bring another

length of pipe 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.

9. 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:

• It is recommended that horizontal through wall installations have 3 to 5 feet (91 to 152 cm) of vertical

pipe in the system to help naturally draft the unit in the event of extreme weather or a power outage.

• 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 draft 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.

• Follow vent manufacturer guidelines for installation of venting. High temp Sealent must be used when

connecting vent pipe to the unit’s starter pipe. Improper seals at the vent joints may cause combustion
by-products to leak into the room where installed - seal as required.

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 # 3 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 Fuel will not light.

9. Control settings (Heat Level) has no effect on the fire.

10. The stove keeps going out.

11 The agitator does not turn.

*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 # 3 light is flashing (unit may be out of fuel)

• Check the Door and Ash Pan door - THEY MUST BE CLOSED TIGHT.

• See section 8 “The Fuel will not light”.

• 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 may cause the vacuum switch to open or 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: The unit may require a change to the vent system or installation of fresh air to correct Air to

Fuel ratio problems if unable to achieve proper damper setting.

• 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. See section #3 - The
Exhaust Blower will not function normally.

• Poor Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove

burning

18

Troubleshooting

• 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 agitator to make sure it is turning properly

3. The exhaust motor will not function normally.

• Open the access panels; check all connections against the wiring diagram.

• Check the Exhaust Blower voltage across the blower motor wires (>=115V on #5 setting and >= 75V
on #1 setting). – Replace the Circuit Board if the Voltage reading is less than 75 V. with a line voltage
of >115 V AC.

• Clean all exhaust passages and venting.

4. Light # 3 on Heat output bar flashing (The Exhaust Temp. Switch contacts have opened.)

• Stove ran out of fuel - check fuel level in the hopper

• See sections #2 - Stove will not operate when hot, #3 - The Exhaust motor will not function normally,
and #5 - Unit is on but auger does not turn at all for more suggestions.

• 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.

• To reset Circuit Board after a trouble code - push the ON/OFF button

5. Unit is on but auger motor does not turn at all.

• Check the Door and Ash Pan door - THEY MUST BE CLOSED TIGHT.

• 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**

• Auger stopped running. Pinch, break or blockage in Vacuum Hose - Check hose for pinch points or
damage, replace or re-route as required. Blow out Vacuum Hose

• Damage to wires between Circuit Board and Vacuum Switch and Auger Motor - Inspect wires and
connectors

• Vacuum Switch failure - Bypass the vacuum switch, if this corrects the problem check for above
problems before replacing the Vacuum Switch.

• Blocked exhaust / venting system - Have stove and venting cleaned and inspected.

• Check Vacuum levels at the Vacuum Switch, with a Magnahelic Gauge (readings must be above .07”
W.C. on low fire).

6. Light # 4 on Heat output bar flashing The 200 °F ( 93 °C) high limit temperature sensor

has tripped.

• Reset sensor and determine cause. Was it Convection Blower failure or Circuit board control
problems?

7. The convection blower will not function normally.

• Clean all grill openings at the back and below unit .

• Check the Voltage across the blower wires, It should adjust with the heat output settings. If not
contact your local dealer for service.

19

Troubleshooting

8. Ignitor - the pellets will not light.
NOTE: The ignitor should be bright orange in color.

• 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 pulling the ignitor tube out
towards the liner.

• Check to see if the exhaust blower is operating. If not, contact your local dealer for service.

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.

• Check position of the Thermostat slide switch on the Circuit Board.

• 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 fuel 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 fuels will require slightly higher settings).

• Set the auger trim up one setting

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 fuel will require slightly higher settings).

• Did the power go out?

• Contact your local Dealer for service.

11. The agitator does not turn.

• Ensure unit has finished start-up.

• Ensure agitator is locked into the drive shaft properly and is not jammed.

• Check drive chain assembly and gear motor for damage.
