4. VENTING SYSTEM
CAUTION
CONNECT THIS STOVE ONLY TO A LISTED
PELLET EXHAUST VENTING SYSTEM FOR USE
WITH SOLID FUEL OR TO A LINED CHIMNEY
CONFORMING TO NATIONAL AND LOCAL
BUILDING CODES.
CAUTION
DO NOT CONNECT THIS STOVE TO ANY
OTHER EXISTING VENTING SYSTEM SERVING
ANOTHER APPLIANCE.
CAUTION
THE VENTING SYSTEM MUST BE COMPLETELY
AIRTIGHT AND PROPERLY INSTALLED.
ALL VENT CONNECTOR JOINTS MUST BE
SEALED AND FASTENED IN ACCORDANCE
WITH THE PELLET VENT MANUFACTURER’S
INSTRUCTIONS TO ENSURE CONSISTENT
PERFORMANCE AND AVOID SMOKE AND ASH
SPILLAGE..
CAUTION
DO NOT INSTALL A FLUE DAMPER IN THE
EXHAUST VENTING SYSTEM OF THIS UNIT.
CAUTION
DO NOT CONNECT TO OR USE IN
CONJUNCTION WITH ANY AIR DISTRIBUTION
DUCTWORK.
CAUTION
THE VENTING SYSTEM SHOULD BE CHECKED,
AT LEAST TWICE A YEAR FOR ANY BUILDUP
OF SOOT OR CREOSOTE.
4.1 GENERAL
Even though the chimney draft is mechanical, a sui-
table venting system will ensure a natural draft which
will prevent smoke spillage in your home if a power
outage occurs. Moreover, a suitable venting system
conguration will help getting the best efciency out
of your stove when installed in accordance with the
required EVL.
4.2 RECOMMANDATIONS
In Canada, we recommend that you use a listed pel-
let vent that meets the CAN/ULC S609 or ULC/ORD
C441 Standard. A pellet vent listed to ULC S629M is
also suitable for installation with this stove.
For the United States, we recommend that you use a
listed pellet vent that meets the UL 641 Standard. A
pellet vent listed to UL 103 is also suitable for instal-
lation with this stove.
This stove can be vented in an existing factory-built
or masonry chimney with the addition of a stainless
steel liner, provided the chimney is more than 4" in
diameter. The liner should be listed and should meet
the ULC S635 CAN/ULC S640 standard in Canada
and the UL 1777 standard in the USA. Refer to the
instructions provided by the vent manufacturer,
especially when passing through a wall, ceiling or
roof.
The recommended venting system inner pipe diame-
ter is 3". Use a 4" pipe if you have more than 15 feet
of Equivalent Vent Length (EVL).
To calculate the Equivalent Vent Length of your ins-
tallation, use the following conversions:
Qty Type of pipe Equivalent vent
length (EVL)
1 90° elbow or ‘‘Tee’’ 5 feet
1 45° elbow 3 feet
1 foot horizontal pipe run 1 foot
1 foot vertical pipe run 1/2 foot
4.3 EQUIVALENT VENT LENGTH (EVL)
4.3.1 RECOMMENDED EXHAUST VENTING
DIAMETER

Page 10 INSTALLATION MANUAL ECO-55/ECO-55ST
Here is an example to help you calculate Equivalent
Vent Length. On the following gure the EVL can be
calculated like this:
2 feet of horizontal run (2 X 1' EVL) = 2' of EVL
90° elbow or "Tee" (1 X 5' EVL) =5' of EVL
12 feet of vertical run
(12' X 0.5' EVL)
= 6’ of EVL
Termination cap = 0' of EVL
Total EVL = 13' of EVL
Since the total EVL is less than 15 feet, the re-
commended exhaust venting diameter is 3".
4.3.2 INSTALLATION COMPLIANCE
To determine if your installation is compliant, the
exhaust venting system must end within the grid on
the venting system chart. The previous installation
has 2 feet of horizontal run and 12 feet of vertical
run. It is thus standard since the venting system ends
in the gridded area.
CAUTION
• Horizontal runs shall not exceed 9 feet.
• Never exceed 30 feet of evl.
CAUTION
TO REDUCE THE RISK OF SMOKE SPILLAGE
THERE SHOULD ALWAYS BE AT LEAST ONE
FOOT OF VERTICAL RISE FOR EACH FOOT OF
HORIZONTAL RUN. IN ALL CASES, AT LEAST 3
FEET OF VERTICAL RISE IS NEEDED.
WARNING
TERMINATION OF A SIDE WALL VENT SHOULD
BE LOCATED TO AVOID PERSONAL BURN
INJURY, FIRE HAZARD AND INTERFERENCE
WITH OR DAMAGE TO ADJACENT
PROPERTIES. EXHAUST GASES CAN REACH
TEMPERATURES OF 500°F (260°C) AND CAUSE
SERIOUS BURNS.
WARNING
TERMINATION COLLAR (SPARK ARRESTER)
IS MANDATORY AND MUST BE CLEAR OF ANY
DEBRIS AT ALL TIME.

6. MOBILE HOME INSTALLATION
NOTICE
For mobile home installation, it is mandatory to
connect the stove to an outside combustion air
source. Insulated pipe should never exceed 10
feet.
When installed in a mobile home, the stove must be
anchored to the oor with two screws. Use the two
anchoring holes located on each side of the pedes-
tal, as shown on the right gure.
For use in a mobile home in Canada, this pellet
stove must be connected to a vent system certied
according to the standard or ULC/ORD-C441 CAN/
ULC-S609. A vent system meeting the requirements
of ULC S629M can also be used.
For use in a manufactured home in the United States,
this pellet stove must be connected to a venting sys-
tem that meets the requirements of UL 641 standard.
A vent system that meets the requirements of UL 103
standard may also be used.
7. INSTALLING A THERMOSTAT
Using a thermostat will help you maintain a constant
temperature throughout the house. A low voltage
thermostat (24 volts) is required. A xed wall mount
or hand held model can be used.
NOTICE
Thermostat manufacturer’s instructions always
override the information published in the following
section.
7.1 THERMOSTAT LOCATION
Location of the thermostat is very important to obtain
comfort and efciency from your stove.
Locate the thermostat 4 to 5 feet above the oor in
accordance with applicable building codes.
Install the thermostat in a location that provides
good airow characteristics and avoid areas behind
doors, near corners, air vents, direct sunlight or heat
generating devices.
If the thermostat is installed in the same room as the
stove, it should also be located at least 15 to 20 feet
from the stove. To prevent cycling, you should avoid
installing the thermostat on a poorly insulated outside
wall or directly in front of the stove.
A Thermostat
BMinimum 15'
NOTICE
Installing the thermostat in front of the stove or
in front of a window will tend to make the stove
cycle too often and wear components prematurely.
See operation’s manual for more details on how to
operate the stove with the proper pilot mode.

Page 16 INSTALLATION MANUAL ECO-55/ECO-55ST
7.2 WIRED THERMOSTAT
Before installing the thermostat, unplug the power
cord from the power outlet.
First, connect the two thermostat wires to the terminal
block located at the rear on the right hand side of the
stove when facing it. Loosen the two middle screws
and insert the wires in the terminals. Tighten the two
screws. Open the thermostat and connect the wires
as per the manufacturer’s instructions.
Open the thermostat and connect the wires as per
the manufacturer’s instructions.
Connect one wire on “RH” and the other wire on “W”.
Red wire jumper can remain installed. For further in-
formation refer to the manufacturer’s instructions.
7.3 WIRELESS THERMOSTAT
If you are using a wireless thermostat or a hand
held thermostatic remote control, connect the two
thermostat wires to the terminal block located at the
rear on the right hand side of the stove while facing it.
If the receiver wires are equipped with quick-connect
terminals you can connect them directly to the stove’s
wiring harness.
To do so, open the right hand side decorative panels
and disconnect wires (B) and (C) attached to the rear
of the terminal block (A) and connect them to the re-
ceiver.
8. COMBUSTION AIR SUPPLY
NOTICE
For mobile home installation, it is mandatory to
connect the stove to an outside combustion air
source. Insulated pipe should never exceed 10
feet.
It is recommended to install an outside air inlet in or
near the room where the stove is installed. When
doing so, it is preferable to choose a wall which is
not exposed to dominant winds, depending on the
conditions surrounding your house.

Page 17INSTALLATION MANUAL ECO-55/ECO-55ST
An insulated 3” inside diameter metallic pipe, either
exible or rigid, must be attached to the fresh air in-
take (D).
To complete the installation, make a hole of 1/4" to
1/2" (6 mm à 13 mm) bigger than the insulate pipe
diameter in the outside wall of the house at the
chosen location. From outside, place the outside air
inlet cap (E) in the hole (open side down) and fasten
the register to the wall, with screw.
Place the insulated pipe (A) over the register tube
and over the replace outside air connector (D).
At each end, carefully pull back the insulation and
plastic cover, exposing the exible pipe. Attach the
exible pipe using pipe clamps(C).
For a better seal, you may also use aluminum tape.
Wrap the tape around the joint between the exible
pipe and the air inlets. Carefully push the insulation
and plastic cover back over the pipe. Fix the plastic
in place using aluminum tape.
A rodent guard (minimum 1/4” wire mesh) must be
used at the termination. All connections must be
secured and airtight by either using the appropriately
sized hose clamp and/or UL-181-AP foil tape.
Make sure that the fresh air intake back draft shutter
functions freely. The fresh air intake back draft shutter
is located in the back of the stove.
8.1 SOURCES OF OUTSIDE COMBUSTION
AIR
CAUTION
IT IS FORBIDDEN TO DRAW COMBUSTION AIR
FROM A BASEMENT, AN ATTIC, A GARAGE OR
ANY CONFINED SPACE
• You can draw air from a ventilated crawl space
underneath the oor.
• You can draw air directly from an outside wall,
behind the stove.
