Introduction

IMPORTANT SAFETY DATA:

Please read this entire manual before installation and use of this pellet fuel burning room heater. Failure
to follow these instructions could result in property damage, bodily injury or even death.

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.

Contact local building officials about restrictions and installation inspection requirements in your area.

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 use of grates or other methods of supporting the fuel is not permitted.

This unit is designed to burn pelletized wood fuel only. Do not use any other type of fuel, this will void
any warranties stated in this manual.

THE USE OF CORDWOOD IS PROHIBITED BY LAW.

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.

It is advisable to clean the exhaust vent bi-annually or every two tons of pellets.

The grounded electrical cord should be connected to a standard 220-240 volts, 50 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 520 watts. (2.26-2.46 Amps).

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

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.

Be sure to maintain the structural integrity of the home when passing a vent through walls, ceilings, or
roofs.

The ash pan and viewing door must be locked securely for proper and safe operation of the pellet
stove.

Introduction

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, we grant no warranty
implied or stated for the installation or maintenance of your stove. Therefore, Sherwood Industries Ltd.
assumes no responsibility for any consequential damage.

PELLET QUALITY:

PELLET QUALITY IS IMPORTANT, PLEASE READ THE FOLLOWING PAGE.

Your pellet stove has been designed to burn wood pellets only. Since there are many manufacturers
of wood pellets, it is important to select pellets that are free of dirt or any impurities. 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 DIFFER,
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 caused by the quality of wood pellets used.

P.F.I. PELLET STANDARDS:

Fines ...................................1% maximum through a 1/8” screen

Bulk Density.........................40 lbs. per cubic foot minimum

Size.....................................1/4” to 3/8” diameter 1 – 1.5” long maximum

Ash Content .........................1% maximum

Moisture Content..................8% maximum

Heat Content .......................approximately 8200 Btu per lb. minimum

Check the burn-pot liner periodically to ensure that the holes are not blocked with clinkers, (clinkers are
silica in the fuel that form a hard mass during the burning process). If they are blocked, remove the liner
(when the unit is cold) and clean the clinkers out. The liner should be cleaned or scraped once every 2-3
days depending on wood pellet quality. Clean the holes in the lines with a small pointed object.

Store pellets at least 36” (1 m) away from the pellet stove.

WARNINGS AND RECOMMENDATIONS:

A. Do not abuse the glass by striking or slamming the door shut.

B. Do not attempt to operate the stove with broken glass.

C. Do not attempt to open the door and clean the glass while the unit is in operation. 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.

4

Introduction

D. Do not use abrasive cleaners to clean the surface or any part of the stove.

E. It is recommended that the unit be secured into its’ position in order to avoid any displacement.

F. Never use gasoline, gasoline-type lantern fuel, kerosene, or similar liquids to start the fire. Keep all

such liquids well away from the pellet stove while it is in use.

G. 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. The ashes should be retained in the closed container until all cinders have
thoroughly cooled before disposing of them.

H. Make sure the ash pan is closed tightly during the operation of the stove.

I. Fresh air intake is strongly recommended. Failure to install intake air may result in the unit smoking

during power failures as well as improper combustion.

NOTE: Fresh air is mandatory on all units installed in “Mobile Homes” and “Air Tight” homes.

J. GOLD BARS: Please clean all fingerprints off of all gold parts, with denatured alcohol on a soft cloth,

before firing the unit each time. Fingerprints, etc. can become permanently etched into the gold if not
removed before operating the pellet heater.

K. 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.

KEEP ASH PAN FREE OF RAW FUEL. DO NOT PLACE UNBURNED OR NEW PELLET FUEL IN
ASH PAN. A fire in the ash pan could be the result.

AUTOMATIC SAFETY FEATURES OF YOUR PELLET STOVE:

A. The stove will shut off when the fire goes out and the exhaust temperature drops below 120°F

(49°C) for Circuit Board and 140°F (60°C) for Timer Control.

B. The stove has a high temperature safety switch. If the temperature at the back of the firebox

reaches 200°F (93°C), the auger will automatically stop and the stove will shut down when the
exhaust temperature cools. If this happens, call your local dealer to reset the 200°F (93°C) high
limit switch. ALSO FIND THE REASONS WHY THE UNIT OVERHEATED.

C. The unit has a convection fan control over-ride. This function causes the convection fan to reach

its’ full speed when the temperature at the back of the firebox reaches 160°F (71°C). This is a
normal safety feature of your unit. To compensate for the fan cycling action that may occur, turn
up the blower control proportionately to the heat output.

D. If the power goes out, the unit will stop running. When the power comes back on, the stove will

not restart unless the exhaust temperature is still above 120°F (49°C) for Circuit Board and 140°F
(60°C) for Timer Control.

HOW TO TURN ON AND OPERATE YOUR PELLET APPLIANCE (TIMER CONTROL):

1. Check and fill hopper with pellets.

2. Switch on power by pushing the start-up switch
once only.

3. Turn the Dial-A-Fire knob to the 12 o’clock
position. (Lower grade pellets may need a

higher setting on the feed rate).

NOTE: unit will take longer to light if the hopper

has been completely emptied.

4. Wait until the fire is established, then turn knob
“B” to the desired heat output. (The stove may
not be able to burn in the BLUE ZONE if poor
quality wood pellets are being used.) Adjust
the Slider Damper to the appropriate setting.

5. If the stove should shut off after 15 minutes
and there is still a fire in the firebox – press
the start-up switch once more. If the fire went
out, return to step number 2 and re-light the
stove.

6. Adjusting the blower speed control knob will vary the rate of airflow into the room by varying the
speed of the convection blower.

*Note: The convection blower may cycle to high automatically, depending on the setting of the controls.

This is a normal safety feature of the unit.

TURNING OFF YOUR PELLET STOVE:

To turn your stove off, simply turn the HEAT OUTPUT knob (knob “B”) counter-clockwise until the knob
clicks to the “off” position. This will stop the feed of pellets. The blowers will continue to run and cool
the stove. When cool enough the stove will shut down.

SPECIAL NOTES: The flashing green light corresponds to the auger feed rate.
The scale on the Dial A Fire knob represents a range, not exact times. Wood pellets of differing quality
may affect the performance of the stove. If the stove has trouble operating at the ends of its’ range,
turn the heat output knob back slightly.

ROUTINE CLEANING AND MAINTENANCE:

The following list of components should be inspected and maintained routinely to ensure that the appliance is
operating at its’ optimum and giving you excellent heat value:

2-3 DAYS/WEEKLY SEASON or 2 TONS OF FUEL
Burn Pot and Liner Exhaust Vent
Ash Pan Fresh Air Intake Tube
Inside Firebox Blower Mechanisms
Door Glass Heat Exchanger Tubes
Heat Exchanger Tubes Behind Firebox Liners
Ash Pan and Door Gaskets All Hinges
Door Latch Post-Season Clean-up

BURNER POT AND LINER

This is the ‘pot’ where the pellets are burned. Every two to three days (when the unit is cold), remove the burn­pot 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. Push the liner up against
the ignitor tube.

TOOLS REQUIRED TO CLEAN UNIT:

Torx T-20 Screwdriver, 5/16” wrench or
socket, Brush, Soft Cloth, Vacuum with fine
filter bag

ASH PAN AND DOOR GASKETS

After excessive use, the gasketing may come
loose. To repair this, glue the gasketing on
using high-temperature fiberglass gasket
glue available from your local dealer. This is
important to maintain an airtight assembly.

DO NOT PLACE UNBURNED OR RAW
PELLET FUEL IN ASH PAN.

To remove the burn pot and burn pot liner, open the door using the door handle provided (located on the left­hand 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.

ASH REMOVAL:

CAUTION WHEN VACUUMING FLY ASH: BECAUSE THE FLY ASH IS VERY FINE, THE USE OF A FINE
FILTER VACUUM BAG WILL BE REQUIRED TO PREVENT ASH FROM BEING BLOWN BACK INTO THE
ROOM. Please pay special attention that there are no hot ashes in the firebox or there could be a possibility of

a fire hazard inside the vacuum cleaner. Place all hot ashes into a noncombustible container.

FREESTANDING ASH PAN:

This part is located under the burner, in the pedestal, and has a latching mechanism to secure it. To remove the
ash pan, unlock the latch on the 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.

DO NOT PLACE UNBURNED OR RAW PELLET FUEL IN ASH PAN

BLOWER MECHANISMS:

Unplug the stove then open the right/left side panels to access the two blowers. Only the convection blower
motor (on the right side of the stove) will require lubrication. The convection motor has two lubrication holes
on it. Use two drops of SAE 20, light oil to lubricate every six months. Excess oil may damage the motor. The

10

Operating Instructions

exhaust blower’s motor has sealed bearings. DO NOT lubricate this motor.

DOOR GLASS

It is recommended that your dealer replace the glass if broken.

The door glass is made of 5 mm thick, high temperature PYROCERAMIC. The center panel is 229 mm x 330 mm.
To replace the glass, unscrew and remove the four glass retainers. Remove the glass and any broken pieces.
High temperature fiberglass tape should be used around the glass. Replace the glass, center the glass assembly
in the frame, then screw the glass retainers back to the frame. The use of substitute materials is prohibited.

FRESH AIR INTAKE

Inspect periodically to be sure that it is not clogged with any foreign materials.

INSIDE FIREBOX

For bi-weekly clean out, ash may be removed from behind the steel plates by rotating the circular cover to
allow vacuuming behind the plates.

EXHAUST PASSAGES

Removal of the firebox backing for bi-annual cleaning

• Remove the top baffler.

• Lubricate and then remove the 7 screws that hold the brick liner in place. Tilt the top of the brick panel
towards the firebox opening and remove from the firebox.

• Remove the top rod by first removing the screw that holds it in place, then slide the rod sideways.

• Pull the side panels into the center of the firebox, then out.

• Pull the center panel out.

• Clean all passages thoroughly (vacuum recommended).

Installation of firebox backing:

• Install the side panels in place. Insert center panel, hold the panels in place

• Install the top rod by sliding it into one side panel then across into the other panel. Screw rod in place.

• Re-install steel brick liner and screw in place.

• Replace top baffle.

EXHAUST VENT

Soot and Flyash: Formation and Need for Removal - The products of combustion will contain small

particles of flyash. The flyash will collect in the exhaust venting system and restrict the flow of the flue gases.
Incomplete combustion, such as occurs during startup, shutdown, or incorrect operation of the room heater
will lead to some soot formation which will collect in the exhaust venting system. The exhaust venting system
should be inspected at least once every year or after two tons of pellets to determine if cleaning is necessary.
We recommend contacting your dealer for professional cleaning. To remove dust from the vent pipe, tap lightly
on the pipe to dislodge any loose ash. Open the bottom of the “T” to dump the ash, then vacuum as much of
the ash out of the vent pipe as possible.

HEAT EXCHANGER TUBES

This cleaning rod is to be pulled back and forth a few times (ONLY WHEN THE UNIT IS COLD) in order
to clean away any fly ash that may have collected on the heat exchanger tubes. As different types of pellets
produce different amounts of ash, cleaning of the tubes should be done on a regular basis to enable the unit to
run efficiently.

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.
