Introduction
* This manual is designed for the home owner in conjunction with the technical manual. *
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 ⅛” screen
Bulk Density..................40 pound per cubic foot minimum
Size..............................¼” to 5/16” diameter ½ – 1½” 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).

Operating Instructions
Slider/Damper Set-Up:
This is used to regulate the airflow through the pellet stove.
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.
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.
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).
Figure 7: Efficient Flame.
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.

Figure 8: EF5 Burn pot and Liner
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
8). 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.
11
Routine Cleaning and Maintenance
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 fly 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.
FRESH AIR INTAKE (biannually)
Inspect periodically to be sure that it is not clogged with any foreign materials.
EXHAUST PASSAGES (biannually)

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. Tthe convection and the exhaust blower’s motors have sealed bearings, DO NOT lubricate
these motors. 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.
