Introduction
PELLET QUALITY:
PELLET QUALITY IS IMPORTANT, PLEASE READ
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.
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 manufactures. We recommend the use
of pellets that meet or exceed these standards. Ask your dealer for a recommended pellet type.
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.
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.
P.F.I. PELLET STANDARDS:
Fines (fine particles)......1% maximum through a 1/8” screen
Bulk Density..................40 lbs. per cubic foot minimum
Size..............................1/4” to 5/16” diameter 1/2 – 1-1/2” long maximum
Ash Content..................1% maximum (Premium grade)
.................3% maximum (Standard grade)
Moisture Content...........8% maximum
Heat Content.................approximately 8200 BTU per lb. 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.
Store pellets at least 36” (1 m) away from the pellet stove.

Introduction
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.
IMPORTANT SAFETY DATA:
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.
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 IS AIRTIGHT.
SAFETY WARNINGS AND RECOMMENDATIONS:
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 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 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 550 watts (4.6 amp). The stove has a grounded electrical cord and should be
connected to a standard 115 volt, 60-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.

Introduction
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.
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.

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 off when the exhaust temperature cools. If this
happens call your local dealer to reset the 200°F (93°C) high limit switch. FIND THE REASONS WHY THE UNIT
OVERHEATED.
6
Operating Instructions
C) This 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.
D) The unit is equipped with a vacuum switch to monitor the venting; if it becomes blocked the vacuum switch will
turn off the auger and the #2 light on the control board will flash.
THERMOSTAT INSTALLATION:
This stove can be placed into two different thermostat modes:
HI / LOW OPERATION: If the unit has been placed in the HI / LOW mode. The unit will operate on the low setting
when the thermostat is not calling for heat. When the thermostat calls for heat, the unit will go to your selected setting which
is displayed on the control board Heat Output Indicator.
ON / OFF OPERATION: If the unit has been placed in the ON /OFF thermostat mode, when the thermostat
calls for heat, the unit will go through an ignition sequence and light the stove. Once lit the unit will operate at the
selected setting displayed on the control board Heat Output Indicator. Once the thermostat stops calling for heat,
the unit will stop feeding pellets and begin its’ shut down sequence until cold then turn off.
1. Install the Low Voltage Thermostat (max 24V) in a location that will effectively monitor the desired area to be
heated.
2. Open the right cab side to expose thermostat wires and disconnect. Install 18 gauge (see wiring diagram) or
heavier wire through the grommet in the back, from the stove to the thermostat. Connect thermostat wires to red
wires provided.
3. To set the thermostat jumper to the desired mode, remove the two screws holding the circuit board control panel
in place. Lower the board and pull out to change jumper.
A) HI / LOW: when the jumper
is placed on only one of the J9
pins, then the control board is in
a HI / LOW mode of thermostat
operation (factory setting).
B) ON / OFF: If both pins of J9
are jumped (covered) then the
control board is in an ON / OFF
mode of thermostat operation.

Operating Instructions
SLIDER/DAMPER SETTING:
THE SLIDER / DAMPER MUST BE SET AT TIME OF INSTALLATION.
A Qualified Service Technician or Installer must set the Slider Damper.
The slider damper should be set only on a hot stove (operating for 30 minutes or more) by placing a Magnahelic
Pressure Gauge in the firebox (test port is located in the center of the stove just below the door opening). Set the
slider damper so that the pressure reads
0.11” w.c. (.028 KPa) on HIGH HEAT LEVEL and when turned down to
LOW HEAT LEVEL, a 0.07” to 0.11”w.c. (0.018 to 0.028 KPa) reading should be achieved
Exhaust Blower
The pressure readings are taken through a
hole in the front of the firebox under the door,
using a Magnehelic Gauge.
Exhaust
Channel
Slider
Damper
Note: Some parts have been removed in order to see
components more clearly.
The slider damper is located behind the left cab side. The door must be open for the cab side to be removed on all
models. On freestanding model loosen the two T20 torx screws, one above and one below hinge, swing open left
panel to access. On insert model remove the two T20 torx screws on the front, one above and one below hinge,
and the one T20 at the top of the cab side under the top front.
• If the fire goes out and the heat output has been set on the lowest setting, use the auger trim button to increase
feed rate or the Slider Damper should be pushed in slightly, decreasing the air in the firebox. Check the firebox
vacuum and re-set if necessary.
• If after long periods of burning the fire builds up and over flows the burn pot or there is a build up of clinkers
This would be a sign that the pellet quality is poor and the slider damper must be pulled to compensate, to give
the fire more air.
The easiest way to make sure that an efficient flame is achieved is to see the characteristics of the fire.
• A tall and lazy flame with dark orange tips requires more air – Open slider.
• A short and brisk flame, like a blowtorch, has too much air – Close slider.
• If the flame is in the middle of these two characteristics with a bright yellow/orange, active flame then the air
may be correct for proper operation - monitor for build up.
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 this happens, pull the Slider Damper out slightly to increase the air flow to the fire.

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 AJAR
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.
To OPERATE:
When a fire has been established, the System Light will turn solid, the Auger Light will continue to flash to the
corresponding Heat Level setting. The Heat Level button can now be pressed 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. When the air jacket reaches 160° F (71° C) the convection blower will come ON High, cooling the unit. 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 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
STOVE CONTROLS).
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 STOVE CONTROLS). 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.

Pot
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. Open the
door using the door handle provided located on the right-hand side of the stove, swing the door open. 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 burn-pot. 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.
ASH PAN AND DOOR GASKETS (weekly)
After excessive use the gasket may come loose. To repair this, glue the gasket on using high-temperature fiberglass
gasket glue available from your local ENVIRO dealer. This is important to maintain an airtight assembly.
ASH PAN (weekly)
The ash pan is located under the burner. 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.
DO NOT PLACE UNBURNED OR RAW PELLET FUEL IN ASH PAN.
Freestanding:
To remove the ash pan, simply turn the knob and pull out towards the front.
Insert:
To remove the ash pan open the door, remove the burn pot, then pull the ash pan out.

Routine Cleaning and Maintenance
���� ������� ���
HEAT EXCHANGER TUBES (weekly)
Open the door and the rod is located under the unit top, in the center
of the stove just behind the door (see figure to left). This handle is to
be pushed in and out 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.
EXHAUST PASSAGES (season)
Removal of the firebox backing for biannual cleaning:
• Open the door by lifting the handle, Remove
the burn pot and burn pot liner.
• Lubricate all screws with penetrating oil.
• Remove the four screws that hold the Brick
liner retainers in place. Remove Side Brick
liner by sliding forward then out.
• Pull the center panel out.
• Vacuum thoroughly.
Installation of firebox backing:
• Insert center panel with backing.
• Place the two side panels back into the
firebox and reinstall the two retainers using
two screws on each side.
• Replace the burn pot and burn pot liner
• Close the glass door and secure.
• Clean thoroughly.
EXHAUST VENT (season)
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.
DOOR GLASS
It is recommended that your dealer replace the glass if broken.
The door glass is made of high temperature PYRO CERAMIC 5 MM thick. The center panel is 15.4 x 9.0 inches (39.0
cm x 22.9 cm) and side panels are 2.6 x 9.0 inches (6.7 cm x 22.9 cm). They must be replaced with (PART # EF062). Substitute materials will not be permitted.
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.
11
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” (15.2cm) in diameter, or over 28 sq. inches (180.6 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 YOUR PELLET APPLIANCE FROM THE PALLET:
To remove your new stove from its pallet, remove the two screws securing the bottom to the pallet. On the
freestanding model one can be easily seen from behind but to access the second the ashpan must be removed. On
the insert model there is one screw on either side of the bottom.

VENT TERMINATION REQUIREMENTS:
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 Sherwood Industries Ltd’s. control, we grant no guarantee
against such incidents.
IT IS RECOMMENDED THAT AN AUTHORIZED DEALER/INSTALLER INSTALL YOUR PELLET STOVE

THROUGH WALL INSTALLATION:
The MERIDIAN can be vented through the wall using two different methods. Only use vent of (L or PL) type with
an inside diameter of 3 or 4 inches (7.6 or 10.1 cm)
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.
STRAIGHT THROUGH THE WALL.
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.
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.
3.
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” (254 mm) diameter hole for a 3” (76 mm) vent pipe or
an 11” (279 mm) hole for a 4” (101 mm) vent pipe.
4.
Install the wall thimble as per the instructions written on the thimble. Maintain an effective vapour barrier
in accordance with local building codes.
5.
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.
6.
Install the fresh air intake.
7.
Connect the exhaust vent pipe to the exhaust pipe on the stove. Seal all connections with high temperature
silicone
8.
Push the stove straight back, leaving a minimum of 3” (7.6 cm) clearance from the back of the stove to the
wall. Seal the vent pipe to the thimble with high temperature silicone.
9.
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.
10. 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 with rodent screen can be used as a termination. The elbow must be turned down to prevent rain
from entering.

VERTICAL INSTALLATION:
1. Choose a stove location that is ideal. See the section Deciding Where to Locate Your Pellet Appliance.
2. Place the unit on the hearth pad (if installed on a carpeted surface) and space the unit in a manner so
when the pellet vent is installed vertically, it will be 3” (7.6 cm) away from a combustible wall.
3. 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 2 1⁄8” (5.4 cm) in diameter.
4. Install the fresh air intake pipe.
5. Install the tee with clean out.
6. Install the pellet vent upward from there. When you reach the ceiling, make sure that the vent goes
through the ceiling fire stop. Maintain a 3” (7.6 cm) distance to combustibles and keep attic insulation
away from the vent pipe. Maintain an effective vapor barrier
7. Finally, extend the pellet vent to go through the roof flashing.
8.
Ensure that the rain cap is approximately 36” (91.4 cm) above the roof.

There are two parts to the Meridian insert pedestal and they can be found
inside the hopper. Place unit on its’ back. Two hex head screws are used
on each side of the pedestal (refer to figure on right). Using a 5/16”
wrench or socket attach the pedestal to the bottom of the unit.
OPTIONAL:
There are two leveling legs and they can be found
inside the manual bag. Each leveling leg consists of
a long bolt, a hex nut, a washer, and a square bolt
with clip (shown to left). For installation of the leveling
legs the unit should be on its’ back and a 1⁄2” wrench
is required for adjustments.
Install the square bolts into the square holes in the back corners of the
bottom. The square bolt should be inserted from inside the unit so that
the clip will be facing up.
Leveling Legs
Thread hex nut onto the bolt till it is approximately 1” (2.5cm) from the bolt head, slide washer onto bolt. Thread the
bolt into the square nut so length of the bolt shown is the approximately height needed for leveling. When the unit is
up right and the bolts can be adjusted to the exact height required. To lock the bolts at a height tighten the hex nut
and washer against the square bolt
INSTALLING HOPPER COVER AND ADJUSTING HOPPER HEIGHT:
The hopper cover initially comes upside-down on top of the hopper. To install the hopper cover flip the cover over
and fasten in place with four T20 screws shown in bottom left figure.
The back height of this unit can be set to one of three heights; 19” (48.3cm), 211⁄8” (53.7cm), 221⁄4” (56.5cm). The
hopper should be set to the maximum height that can be used in the installation.
To change the height of the hopper back up or down, remove the seven T20 screws, three on each side and one on
the back. The screw placement is shown in bottom right figure. Move the hopper assembly to the required setting
and replace the screws. When the hopper back is in place it is recommended that silicone is used to seal the bottom
lip of the hopper back and sides

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:
The stove will not start.
The stove will not operate when hot.
The exhaust blower will not function normally.
The convection blower will not function normally.
Ignitor : The pellets will not light.
The auger motor does not function normally.
Control settings (heat level) has no effect on fire.
The stove will not shut off.
The stove keeps going out.
*NOTE: All troubleshooting procedures should be carried out by qualified technicians or
installers.
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.
üCheck the Heat Level Indicator. - If the # 2 light is flashing (see the # 2 light is flashing)
üIf the unit still does not start, contact your local service dealer for service.
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. (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.
29
Troubleshooting
üCheck the Exhaust Blower voltage across the blower wires (>=114V on #5 setting and >= 82V on #1 setting).
– Replace the Circuit Board if the Voltage reading is less than 82V. with a line voltage >115Vac.
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.
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.
The exhaust motor will not function normally
üOpen the left side access panel; check all connections against the wiring diagram.
üSee above section.
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 (>=114V on #5 setting and >= 82V on #1 setting). Replace the Circuit Board if the Voltage reading
is less than 82V. with a line voltage >115Vac.
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

Troubleshooting
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**
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 sensor, does the Convection blower come on high if not replace the blower?
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.
Igniter- 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.
NOTE: The ignitor should be bright orange in color. If not replace the ignitor.
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.
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.
