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
conguration will help getting the best eciency 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
