Cambridge Pellet Stove Installation and Operation Manual 15
4VENTING SYSTEM
4.1 General
Even though the chimney draft is mechanical, a suitable 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 configuration will help getting the best efficiency out of your stove when installed in
accordance with the required EVL (see Section 4.3 Equivalent Vent Length (EVL)).
Even the best stove will not function safely and efficiently as intended if it is not connected to a
suitable venting system.
4.2 Recommendations
In Canada, we recommend that you use a listed pellet 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 installation 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.
4.3 Equivalent Vent Lengt (EVL)
4.3.1 Recommended Ex aust Venting Diameter
Recommended venting system inner pipe diameter 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 installation, use the following conversions:
Qty Type of pipe Equivalent Lengt (EVL)
1 90° elbow or “T” 5 feet
1 45° elbow 3 feet
1 foot Horizontal pipe run 1 foot
1 foot Vertical pipe run 0.5 foot
CAUTION
•HORIZONTAL RUNS SHALL NOT EXCEED 9 FEET.
•NEVER EXCEED 30 FEET OF EVL.

16 Cambridge Pellet Stove Installation and Operation Manual
Here is an example to help you calculate Equivalent Vent Length. On the following figure the EVL can
be calculated like this:
•2 horizontal run of 1’ = (2 X 1’) X 1’ = 2’ of EVL
•1 elbow 90° or "Tee" = 5’ of EVL
•3 vertical length of 4’ = (3 X 4’) X 0.5’ = 6’ of EVL
•Total EVL = (2’ + 5’ + 6’) = 13’
Since t e total EVL is less t an 15 feet, t e recommended ex aust venting diameter is 3".
NOTE
DO NOT INCLUDE THE EXTERIOR WALL TERMINATION IN THE
EVL CALCULATION (45° ELBOW AND TERMINATION COLLAR).

Cambridge Pellet Stove Installation and Operation Manual 17
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.
WARNING
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.
4.4 Termination Location
Termination should not be located so that hot
exhaust gases can be a hazard. They can reach
temperatures of 500°F (260°C) and cause serious
burns.
CAUTION
TERMINATION COLLAR (SPARK ARRESTER) IS MANDATORY.

4.5.1 Installation Warnings, Cautions and Recommendations Reminder
CAUTION
•PROFESSIONNAL INSTALLATION IS HIGHLY RECOMMENDED.
•THIS STOVE USES A PRESSURIZED VENTING SYSTEM. ALL VENT CONNECTOR JOINTS MUST BE
SEALED AND FASTENED. YOU MAY USE RTV SILICONE (ROOM TEMPERATURE VULCANISATION),
METALLIC TAPE, AND A MINIMUM OF THREE SELF-TAPING SCREWS AT ALL JOINT
CONNECTIONS TO ENSURE A TIGHT SEAL. CONSULT THE PELLET VENT MANUFACTURER’S
INSTRUCTION TO ENSURE PROPER INSTALLATION, CONSISTENT PERFORMANCE, AND TO
AVOID SMOKE AND ASH SPILLAGE.
•THE CHIMNEY CONNECTOR SHALL NOT PASS THROUGH AN ATTIC OR ROOF SPACE, CLOSET OR
SIMILAR CONCEALED SPACE OR FLOORS OR CEILING.
