8.3 Suitable Chimneys
Your wood insert will provide optimum efficiency and performance when connected to a 6-
inch diameter chimney liner. The connection to a chimney having a diameter of at least 5
inches (Canada only) is permitted, if it allows the proper venting of combustion gases and
that such application is verified and authorized by a qualified installer. Otherwise, the
diameter of the flue should be 6 inches. The reduction of liner diameter to less than 6”
should only be done if the total height of the masonry chimney is greater than 20 feet.
8.4 Liner installation
We recommend the use of a chimney liner
(rigid or flexible) to ensure satisfactory
performance. To ensure an optimal draft, we
also strongly recommend adding a minimum of
12” rigid liner between the top of the masonry
chimney and the rain cap. In all cases, liners
should be installed in accordance with the liner
manufacturer’s instructions, including
instructions for extension above the masonry.
Use Listed Chimney Liners – UL 1777,
CAN/ULC S635 and CAN/ULC S640.
In order to connect the insert to the liner, refer
to Section 9.5 Chimney liner installation.
WARNING: When positioning the unit in a
fireplace opening prior to the flue installation,
install the insert into the opening until the top lip
of air jacket is flush with fireplace facing.
If lag-bolts or anchors are to be used to secure
the insert, the hole locations should be marked
with the unit in place. Remove the insert and
locate the anchors.
