Introduction
PELLET QUALITY:
Pellet quality is important, please read the following:
Your Vista Flame 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.
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.

Introduction
IMPORTANT SAFETY DATA:
Please read this entire Owner’s Manual before installing or operating your Vista Flame 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 Vista Flame 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).
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 (4.5 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 Vista Flame
dealer. The VF100’s maximum power requirement is 520 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 Vista
Flame 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
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 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).
SLIDER/DAMPER SETTING:
The slider/damper must be set at time of installation. This is used to regulate the airflow through
the pellet stove. 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
HIGH: Pull out
handle until
an efficient
flame is
achieved
LOW: Push
handle
slightly in.
Figure 1: Slider /
damper positions.
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 the fire should happen to go 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 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.
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). The best settings are a reading of 0.12 inches of water column (30 Pa) on the
high fire setting. Some fuels may require higher or lower settings. Taking a reading of vacuum
pressure inside the firebox with a magnehelic gauge can be used to set the slider for best combustion.

Operating Instructions
STOVE CONTROLS:
1. AUGER TRIM: The Auger Trim Button is used to increase or decrease the feed rate on LOW, ONLY.
Push the Auger Trim button until the number 1 and 5 lights appear on the Heat Level Indicator. This
will increase the feed rate to 4 seconds ON time Auger pulse. This is done only on LOW to allow the
burning of poor quality fuels. Push the button until the number 1 and 4 lights appear, this will reduce
the Auger On time to 2 second. This setting is for high-grade fuel only. Push the button until just
the number 1 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. If the blower
is left off, and the sensor located on the air jacket reaches 160 °F (71 °C), the convection blower
will automatically come on HI speed to cool the unit. Leave the convection blower ON for peak
efficiency

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 (see
“OPERATING INSTRUCTIONS; STOVE CONTROLS”).
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, 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; 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 “OPERATING INSTRUCTIONS; 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.

Routine Cleaning and Maintenance
NOTE: Do not use abrasive cleaners to clean the surface or any part of the stove.
The following should be inspected periodically to ensure that the appliance is operating at its optimum
and giving you excellent heat value:
2-3 Days / Weekly Bi-Annually 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 & Door gaskets All Hinges
Door Latch Post Season Clean-up
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.
Ensure the unit is cold before cleaning. 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 the front of the burn pot up
first, then sliding the assembly from the air intake tube and the ignitor cartridge. Using a metal scraper,
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 and the front tabs are placed in the firebox. 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.
INSIDE FIREBOX (weekly)
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.
ASH PAN AND DOOR GASKETS (weekly)
After extended use the gasket may come loose. To repair or replace this, glue the gasket on, using high-
temperature fiberglass gasket glue. This is important to maintain an airtight assembly.

ASH PAN (2-3 days)
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.
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 ash pan and inside the pedestal. CAUTION: 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 non-combustible
container.
FREESTANDING ASH PAN:
The VF100 pellet stove freestanding’s ash pan 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 ash pan
and then pull the pan out.
INSERT ASH PAN:
The VF100 pellet stove insert’s ash pan is located behind the lower grill.
Routine Cleaning and Maintenance

HEAT EXCHANGER TUBES (2-3 days)
The handle for the heat exchanger cleaning rod is pointed out in Figure
5. This handle 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.
FRESH AIR INTAKE (season)
Inspect periodically to be sure that it is not clogged with any foreign
materials.
EXHAUST PASSAGES (season)
For bi-weekly clean out, ash may be removed from behind the steel
plates by rotating the circular covers located behind the right and left side panels. Loosen the screw on
the disks and open, this will allow vacuuming behind the firebox liner’s plates.
Removal of the firebox backing for bi-annual cleaning:
• Remove the top baffle.
• Lubricate and then remove the seven (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 and vacuum all passages thoroughly.

11
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 (season)
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.
BLOWER MECHANISMS (season)
Unplug the stove then open the right/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 drops of SAE 20 light oil to lubricate every six
months. Excess oil may damage the motor. The 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. 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 use
only part EF-062.
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 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.
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.

CLEARANCES TO COMBUSTIBLES - FREESTANDING:
When installing this unit on a combustible floor (for example linoleum, hardwood flooring) a non-
combustible hearth pad must be under the unit. The pad must extend at least the width of the appliance
[22” (558 mm)] and at least the depth of the appliance plus 6” (153 mm) in front of the appliance [30”

CLEARANCES TO ALCOVE - FREESTANDING:

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.
6. When installing an FPI the chimney must be fully lined. Unless the chimney’s inside diameter is less than 6”
(15 cm) around or has a cross section area of 28 inches² (180.6 cm²), we strongly recommend lining all masonry
chimneys.
NOTE: Venting terminals shall not be recessed into walls or siding.

HORIZONTAL EXHAUST THROUGH WALL INSTALLATION - FREESTANDING:
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 2” (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.
THROUGH WALL WITH VERTICAL RISE AND HORIZONTAL TERMINATION INSTALLATION - FREESTANDING:
A 45° elbow with a rodent screen may be used in place of the termination cap (or stainless steel
termination hood).
Figure 22 is the recommended installation set up.
Figure 23 is the installation to use if there is a concrete or retaining wall in line with exhaust vent on
a pellet stove. The termination must be 12” (30 cm) from the outside wall and 12” (30 cm) above the
ground.
