Introduction
* This manual is designed for the home owner in conjunction with the technical manual. *
Rating Label Location:
The rating label is located on the inside of the hopper.
Pellet Quality:
Pellet quality is important, please read the following:
Your Enviro pellet stove has been designed to burn ¼” (6mm) dia wood pellets only. DO NOT
use this appliance as an incinerator. DO NOT use unsuitable and non recommended fuels,
including liquid fuels 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.
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 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.
FILLING FUEL HOPPER: Open lid on top of unit, check hopper for foreign objects, empty the bag into
the hopper, DO NOT OVER FILL, and ensure hopper lid closes completely.
Store pellets at least 36” (1 m) away from the pellet stove.
WARNING: Parts of the appliance, especially the external surfaces, will be hot to touch
when in operation so use due care.
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.

Safety Warnings & Recommendations
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.
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 80cm (31½”)
of the front of the unit, 20cm (7⅞”) from each side, and 10cm (4”) 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 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. 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.
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.
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 (3.6 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 432 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.
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 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).

Operating Instructions
Slider/Damper Set-Up:
The Slider / Damper must be set at time of installation. A Qualified Service Technician
or Installer must set the Slider Damper.
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,
refer to Figure 7.
Exhaust Channel
Exhaust Fan
Housing
Slider Damper
Figure 6: 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, adjusting the air to fuel ratio.
Figure 7: Efficient Flame.
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).
Guidelines For Fine-Tuning For Fuel Quality:
Due to fuel quality the slider damper and control board trims may need to be fine-tuned.
1.If the unit builds up on all settings, the slider damper rod should be pulled out in small increments to
give the unit more air.
2.If the unit has excesses ash build-up in the liner on the lower feed settings, the Combustion Blower
Trim should be increased one setting at a time until the problem improves (Factory Setting is #2).
3.If the fire is going out on low because the airflow is too great, the Combustion Blower Trim can be
lowered to the #1 setting.
4.If the stove has excesses ash build-up in the liner on the higher settings the Feed Rate Trim should be
trimmed down a setting at a time until the problem improves (Factory setting is #4).
5.If you need more heat and the fuel has long pellets, the majority are over 1” (2.5cm) in length, the
Feed Rate Trim can be moved up to the #5 setting. NOTE: Only do this if the fuel burns without
building up.

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. 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.

TOOLS REQUIRED TO CLEAN UNIT:
Torx T-20 Screwdriver, ¼”, 5/16” ⅜”, & 7/16” wrench and/or socket, Ash Pan Tool, Brush, Soft Cloth, and
Vacuum with fine filter bag
BURNER POT AND LINER (Checked Daily/Emptied Weekly)
To remove the burn pot and burn pot liner, open the door using the door handle provided (located on the
right-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. 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 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.
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 (Weekly)
There are two (2) sets of exchanger tube scrapers; the
handles are located under the top grill (trivet). Lift the
grill and move the handles all the way 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.

Figure 9: Maxx Burn Heat Exchanger Cleaning.
Routine Cleaning and Maintenance
DOOR GLASS CLEANING (Weekly)
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 fly ash to clean the glass. After the glass has
been cleaned use the dry soft cloth to wipe down the outside and inside of the glass.
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.
ASH BOX (Weekly)
IMPORTANT: The unit must be OFF while the ash pan is removed.
The ash box is located behind the lower door (see Figure 10). To remove the ash box, lift the latch on the
right, open the ash box door, and lift it 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 “Safety
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.
Insert the ash box fully and close ash box
door.
DO NOT PLACE UNBURNED OR RAW
PELLET FUEL IN ASH PAN.
EXHAUST PASSAGES (Biannually)
• Open the firebox door by lifting the handle.
• Remove the burn pot and burn pot liner;
clean both.
• Using a ⅜” socket, remove the two (2) bolts
that hold the firebox liner in place. Vacuum
the firebox and firebox liner thoroughly.
• Open the ash box door; remove the ash box
and cleanout the cavity.
• Clean out the transition box to the
combustion blower (located behind the ash
box)
• Lubricate all screws with penetrating oil.
• Re-install the ash box, firebox liner, burn
pot, and burn pot liner
• Close the firebox and ash pan doors and
secure.

Exclusions and Limitations:
1. This Warranty does not cover tarnish, discoloration or wear on the plating or paint.
2. This Warranty excludes wear and tear or breakage caused by cleaning, moving or service on log set.
3. A qualified installer must install this stove or fireplace. This Limited Warranty covers defects in materials
and workmanship only if the product has been installed in accordance with local building and fire codes;
in their absence, refer to the owner’s manual. If the product is damaged or broken as a result of any
alteration, willful abuse, mishandling, accident, neglect, or misuse of the product, the Limited Warranty
does not apply.
4. The stove must be operated and maintained at all times in accordance with the instructions in the
Owner’s Manual. If the unit shows signs of neglect or misuse, it is not covered under the terms of this
Warranty policy. Performance problems due to operator error will not be covered by the Limited Warranty
policy.
5. As this is a heating appliance some changes in colour of surface finishes may occur. This is not a flaw
and as such is not covered under this warranty.
6. Some minor expansion, contraction, or movement of certain parts and resulting noise, is normal and not
a defect and, therefore, is not covered under this Limited Warranty.
7. Misuse includes over-firing. Over-firing this appliance can cause serious damage and will nullify the
Limited Warranty.
8. The Limited Warranty will cover glass thermal breakage only and will not cover misuse of the stove glass,
including but not limited to glass that is struck, has surface contaminates or has had harsh or abrasive
cleaners used on it.
9. This warranty does not cover products made or provided by other manufacturers and used in conjunction
with the operation of this stove without prior authorization from Sherwood Industries Ltd. The use of
such products may nullify the Limited Warranty on this stove. If unsure as to the extent of this Limited
Warranty, contact your authorized Enviro dealer before installation.
10. Sherwood Industries Ltd. will not be responsible for inadequate performance caused by environmental
conditions.
11. The Limited Warranty does not cover installation and operational related problems such as spillage
caused by environmental conditions. Environmental conditions include but are not limited to nearby
trees, buildings, roof tops, wind, hills, mountains, inadequate venting or ventilation, excessive offsets,
negative air pressures or other influences caused by mechanical systems such as furnaces, fans, clothes
dryers etc.
12. The Limited Warranty is void if:
a) The stove has been operated in atmospheres contaminated by chlorine, fluorine or other damaging
chemicals.

c) Any damage to the unit, combustion chamber or other components due to water, or weather damage
which is the result of, but not limited to, improper chimney/venting installation.
c) Salt air in coastal areas or high humidity can be corrosive to the finish; these environments can cause
rusting. Damage caused by salt air or high humidity is not covered by the Limited Warranty.
13. Exclusions to the Limited Warranty include: injury, loss of use, damage, failure to function due to
accident, negligence, misuse, improper installation, alteration or adjustment of the manufacturer’s
settings of components, lack of proper and regular maintenance, alteration, or act of God.
14. The Limited Warranty does not cover damage caused to the fireplace or stove while in transit. If this
occurs, do not operate the stove and contact your courier and/or dealer.
15. The Limited Warranty does not extend to or include firebox paint, door or glass gaskets with damage
caused by normal wear and tear, or exterior paint discoloration or chipping, worn gaskets, etc.

Warranty
17. Damage to plated surfaces caused by fingerprints, scratches, melted items, or other external scores and
residues left on the plated surfaces from the use of abrasive cleaners or polishes is not covered in this
warranty.
18. The Limited Warranty does not cover tarnish, discoloration or wear on the plated surfaces.
19. The paint on the Metal Brick Liner may peel. This is due to the extreme conditions applied to the paint
during normal usage. It is not a flaw and is not covered under warranty.
20. Sherwood Industries Ltd. is free of liability for any damages caused by the fireplace or stove, as well as
inconvenience expenses and materials. The Limited Warranty does not cover incidental or consequential
damages.

component or apparatus to or from the Enviro fireplace or stove without the express written permission

advertising, packaging literature, or printed material is not part of the Limited Warranty.
23. The Limited Warranty is automatically voided if the fireplace or stove’s serial number has been removed
or altered in any way. If the stove is used for commercial purposes, it is excluded from the Limited
Warranty.
24. No dealer, distributor, or similar person has the authority to represent or warrant Enviro products beyond
the terms contained within the Limited Warranty. Sherwood Industries Ltd. assumes no liability for such
warranties or representations.
