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.
9.4 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.
In order to connect the insert to the liner, refer to Section 9.5 Chimney liner installation.
ATTENTION INSTALLER: 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.
