Introduction
RATING LABEL LOCATION:
The rating label is located on the inside of the ash pan cover.
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..............................” to 5/16” diameter – 1” 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.

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 (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.
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).

light is on, this is for a three (3) second on time (standard setting).
2. CONVECTION BLOWER CONTROL: Used to turn the convection blower ON/OFF. Leave the
convection blower ON for peak efficiency
3. AUGER PULSE LIGHT: This light will flash in conjunction with the auger.
4. MANUAL AUGER FEED: If the unit runs out
of fuel, this button can be used to “prime the
auger system”. This button will turn off after 60
seconds and then must be released and pressed
again.
5. SYSTEM LIGHT: Responsible for signaling
the state of the control board. When the light
is flashing during start-up, the stove is in an
automatic start mode. When the light is solid,
the Heat Level Setting can be altered.
6. ON/OFF BUTTON: Used to turn the unit ON

Operating Instructions
OPERATING YOUR PELLET STOVE:
PRE-BURN INSTRUCTIONS: The burn pot liner holes must be clear and the liner installed properly
against the ignitor tube for proper operation. Check the hopper for enough pellets to start the unit.
DO NOT OPERATE THE UNIT WITH THE DOOR OR ASH PAN OPEN.
MANUAL MODE:
To START: Press the ON / OFF button. The stove will turn on. The system light will flash. The Auger
Light will flash with each pulse of the auger (the Auger Feed Rate is pre-programmed during start-up).
The Heat Level Indicator will show the Heat Level that the stove will run at after start-up.
If this is the first time the unit has been started or the unit has run out of fuel, the auger will need to
be primed. Press the Manual Auger Feed button until fuel starts to drop into the Burn Pot Liner (see
“OPERATING INSTRUCTIONS; CONTROL BOARD FUNCTIONS”).
To OPERATE: When a fire has been established, the System Light will turn solid (after approximately 10
- 15 minutes) and the Auger Light will continue to flash to the corresponding Heat Level setting. The Heat
Level button can now be pressed at this time to change the desired Heat Level Output setting.
The convection blower (room air blower) will turn on. The speed of this blower is controlled by the setting
of the heat level output indicator. The convection blower can be turned OFF by depressing the convection
blower control button. For the best efficiency and to prevent cycling, the convection blower should be
left on at all times.
When operating on LOW HEAT LEVEL, the feed rate can be adjusted, using the auger trim, for different
quality fuels. These settings can be used if the fire keeps going out on low (poor quality fuel). Or if the
low setting is too hot for the room (see “OPERATING INSTRUCTIONS; CONTROL BOARD FUNCTIONS”).
THERMOSTAT / SWITCH MODE:
INITIAL START-UP: See above
OPERATION - HI / LOW mode: When the thermostat contacts are closed the stove settings are
adjustable as per Manual Mode (see above). When the thermostat contacts open, the circuit board will
take control of the settings. The stove will drop down to a low burn until the thermostat contacts close
again. This low burn setting can be adjusted for different fuel qualities (see “OPERATING INSTRUCTIONS;
CONTROL BOARD FUNCTIONS”). The stove will come back to the previous HEAT LEVEL setting when the
thermostat contacts close again.
OPERATION – ON / OFF mode: When the thermostat contacts close, the unit will light automatically.
Once up to temperature, the stove operates the same as in manual mode (see above). When the
thermostat contacts open, the unit automatically begins its shutdown routine. The stove will re-light
when the thermostat contacts close again.
TURNING YOUR PELLET STOVE OFF:
• MANUAL and HI / LOW mode: To turn the unit OFF, simply press the ON / OFF button. This will stop
the feed of pellets. The blowers will continue to operate and cool the stove down. When cool enough,
the stove will turn off.
• ON / OFF mode: To turn the unit OFF, turn the thermostat down or off.
DO NOT unplug unit while Combustion fan is operating.
This may lead to smoke escaping from the stove.

Heat Exchanger Tubes Fresh Air Intake Tube
Ash Pan Blower Mechanisms
Door Glass Heat Exchanger Tubes
Inside Firebox Behind Firebox Liners
Ash Pan and Door Gaskets All Hinges
Door Latch Post Season Clean-up
Figure 2: EF5 Burn pot and Liner
TOOLS REQUIRED TO CLEAN UNIT:
Torx T-20 Screwdriver, 5/16” wrench or socket, Brush, Soft Cloth, Vacuum with fine filter bag
BURNER POT AND LINER (2-3 days)
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 up the front of the burn pot, then sliding the assembly from the air intake
tube and the ignitor cartridge.
This is the ‘pot’ where the pellets are burned. Every two to three days (when the unit is cold), remove
the burn-pot liner from the stove. Using a metal scrapper, 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 burnpot. Place the burn-pot back into the stove, making sure that the pipes are properly inserted into the burn
pot. Place the liner back into the burn-pot, making sure that the ignitor hole in the liner is aligned with
the ignitor tube. Pushing 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.
HEAT EXCHANGER TUBES (2-3 days)
A handle is located under the unit top, in the center of the stove just above the door (shown in Figure
3). This handle is to be pulled up and down 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.
ASH PAN AND DOOR GASKETS (weekly)
After extended use the gasketing may come loose. To repair this, glue the gasketing on using hightemperature fiberglass gasket glue available from your local dealer. This is important to maintain an
airtight assembly.

cleaner handle.
ASH PAN (weekly)
This part is located under the burner, in the pedestal, and has a latching mechanism to secure it. To
remove the ash pan, open the cover from the right hand side, unlock the latch on the pedestal cover and
pull the pan out. Dump the ashes into a metal container stored away from combustibles. 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. Refer to “Warnings and Recommendations” for disposal of
ashes. Vacuum the inside of the ash pan compartment inside the pedestal including the hole at the top
back of the compartment. Replace the ash pan and close pedestal door. DO NOT PLACE UNBURNED
OR RAW PELLET FUEL IN ASH PAN.
DOOR GLASS CLEANING (2-3 days)
Cleaning of the glass must only be done when stove is cold. Open the door by lifting the handle. The glass
can be cleaned by wiping down the outside and inside of the glass with a dry soft cloth.
If the glass has build up that can not be removed with only the cloth, clean the glass using paper towel
and a gas appliance glass cleaner, this may be purchased through most dealers. If a gas appliance glass
cleaner is not available, use a damp paper towel dipped in y ash to clean the glass. After the glass has
been cleaned use the dry soft cloth to wiping down the outside and inside of the glass.

Routine Cleaning and Maintenance
EXHAUST VENT (biannually)
This vent should be cleaned every year or after two tons of pellets. We recommend contacting your
dealer for professional cleaning. To clean 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 (2) 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. Check gaskets and replace if needed.
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.
DOOR GLASS REPLACEMENT
It is recommended that your dealer replace the glass if broken. The door glass is made of high temperature
PYRO CERAMIC. 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 by securing the glass retainers back to the frame ensure the glass is seated in the bottom glass
retainer. The use of substitute materials is prohibited use only part 20-023.

fumes such as stairwells, covered breezeway, etc.
To each side of center line extended above natural gas or propane meter/regulator assembly or
mechanical vent.
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.

OUTSIDE FRESH-AIR CONNECTION:
Outside fresh air is mandatory when installing this unit
in airtight homes and mobile homes.
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.
When connecting to an outside fresh air source, do not use
plastic or combustible pipe. A 1” 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

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 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).
3. 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.
4. 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.
5. Install the wall thimble as per the instructions written on the thimble. Maintain an effective vapour
barrier in accordance with local building codes.
6. Install a length of 3” (76 mm) or 4” (101 mm) vent pipe into the wall thimble. The pipe should install
easily into the thimble.
7. Install the fresh air intake (see OUTSIDE FRESH AIR CONNECTION).
8. Connect the exhaust vent pipe to the exhaust pipe on the stove. Seal the connection with high
temperature silicone.
9. Push the stove straight back, leaving a minimum of 3” (7.5 cm) clearance from the back of the stove
to the wall. Seal the vent pipe to the thimble with high temperature silicone.
10. The pipe must extend at least 12” (30 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.
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.

thermostat is not calling for heat. When
the thermostat calls for heat, the unit will
go through an ignition sequence once
again and relight.
1. Install the wall thermostat in a location
that is not to close too the unit but will
effectively heat the desired area.
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 switch will turn the stove off and the switch will have to be manually reset. To
reset the high limit switch, remove the right cabinet side. The switch is found behind the control panel.
Avoid setting off the high limit switch.

SLIDER/DAMPER SET-UP:
This is used to regulate the airflow through the pellet stove. T
The slider damper is located
behind the left side panel.
To open the left side panel,
undo the one screw located
in the upper front corner of
the cabinet side between the
louvers. Also loosen three
screws down the back of the
side panel.
Figure 29: Slider/Damper Plate in Unit.
The combustion exhaust blower is a variable speed blower controlled by the heat output button. This
blower will decrease the vacuum pressure inside the stove and as the heat output button is turned down.
The vacuum pressure inside the firebox will increase as the combustion exhaust blower increases in
speed (higher heat output setting).
If the fire should happen to go out and the heat output indicator has been set on the lowest setting, the
Slider Damper should be pushed in slightly, decreasing the air in the firebox.
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, active flame
with no black tips then the air is set for proper operation.
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).
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 approximately 0.10 inches of
water column on the high fire setting. Some fuels may require higher or lower settings. The
reading can be taken from the ” (3 mm) hole located on the front of the unit below the door and behind
the magnetic ash lip.

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 # 2 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 pellets will not light.
9. Control settings (Heat Level) has no effect on the fire.
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.
üMake sure the stove is plugged in and the wall outlet is supplying power..
üIf the Control Board has been placed in the ON /OFF thermostat mode, then turn the thermostat up to
call for heat.
üEnsure the burn pot liner is correctly placed in the burn pot
üCheck the Heat Level Indicator. - If the # 2 light is flashing (see the # 2 light is flashing)
üCheck the fuses on the circuit board (see “Troubleshooting - Fuses”).
üIf the unit still does not start, contact your local service dealer for service.
2. The stove will not operate when hot.
üCheck 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.
üCheck the hopper for fuel.
üIncorrect 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. In this case clean the burn pot. (NOTE: unit may
require a change to the vent system or installation of fresh air to correct Air to Fuel ratio
problems).
üCombustion 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.
üCheck the Exhaust Blower voltage across the blower wires (>=114 V on #5 setting and >= 82 on #1
setting). – Replace the Circuit Board if the Voltage reading is less than 82 V. with a line voltage >115
V AC.
üCheck 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).
If the motor fails to reach a 0.10” W.C. readings, then replace the Combustion Blower.
27
Troubleshooting
üPoor Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove burning
or operational.
üExhaust 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.
üCheck the fuses on the circuit board (see “Troubleshooting - Fuses”).
3. The exhaust motor will not function normally.
üOpen the left side access panel; check all connections against the wiring diagram.
üSee “2. The stove will not operate when hot.” section.
4. Light # 2 on Heat output bar flashing
(The Vacuum Switch contacts have opened for more than 15 sec.)
üPinch, break or blockage in Vacuum Hose - Check hose for pinch points or damage, replace or re-route
as required. Blow out Vacuum Hose
üBlocked Hose Barb on Exhaust Channel - Use a paper clip to clean out Hose Barb or remove the Vacuum
Hose from the Vacuum Switch and blow into the hose to remove blockage.
üBlocked exhaust / venting system - Have stove and venting cleaned and inspected.
üSevere 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.
üVacuum Switch failure - Bypass the vacuum switch, if this corrects the problem check for above
problems before replacing the Vacuum Switch.
üDamage to gray wires between Circuit Board and Vacuum Switch - Inspect wires and connectors
üCombustion Blower failure - The Combustion Blower is not turning fast enough to generate the proper
vacuum in the Exhaust Channel. Visual Check; is the blower motor turning? Check the Exhaust Blower
voltage across the blower wires (>=114 V on #5 setting and >= 82 V on #1 setting). – Replace the
Circuit Board if the Voltage reading is less than 82 V. with a line voltage >114 V AC.
üCheck 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).
If the motor fails to reach a 0.10” W.C. readings, then replace the Combustion Blower
To reset Circuit Board after a trouble code - push the ON/OFF button
5. Auger light flashes but auger motor does not turn at all.
üIf 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**
üCheck the fuses on the circuit board (see “Troubleshooting - Fuses”).
6. The 200 °F ( 93 °C) high limit temperature sensor has tripped.
üReset sensor and determine cause – was it Convection Blower failure or 160 °F ( 71 °C) Temperature
Sensor failure? Bypass the 160 °F ( 71 °C) sensor, does the Convection blower come on high if not
replace the blower? If yes, replace sensor (located on the left side of the firewall).
üCheck the fuses on the circuit board (see “Troubleshooting - Fuses”).
28
Troubleshooting
7. The convection blower will not function normally.
üClean all grill openings at the back and below unit .
üPress 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.
8. Ignitor- the pellets will not light.
üEverything else in the stove operates but the ignitor will not light the pellets.
üMake sure the burn pot liner is up tight and square to the ignitor tube by pushing the burn pot back
against the ignitor tube.
üCheck to see if the exhaust blower is operating. If not, contact your local dealer for service.
üCheck the fuses on the circuit board (see “Troubleshooting - Fuses”).
NOTE: The ignitor should be bright orange in color. If not replace the ignitor.
9. Control settings (Heat Level) has no effect on the fire.
üNOTE: 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.
üIf there is no control of the Heat Level button make sure the thermostat is calling for heat.
üCall your local dealer for service.
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.
üCheck to see that the Slider / Damper is in the correct position.
üTurn the Heat Level up slightly (poor quality pellets will require slightly higher settings).
üSet the auger trim till the #1 and #5 lights are illuminated.
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.
üAdjust the Slider / Damper.
üCheck to see if the stove needs a more complete cleaning.
üTurn the Heat Level up slightly (poor quality pellets will require slightly higher settings).
üDid the power go out?
üContact your local Dealer for service.
FUSES:
F1 is the fuse to the inside of the circuit board controls. If F1 has blown there may have been an input
power overload or a short in the convection fan.
F2 fuse closest fuse to the outside edge of the circuit board controls. If fuse F2 has blown then there
was a electrical overload problem with one of the following parts: ignitor, auger motor, high limit switch,
or exhaust blower.
