Escape 1800 Insert Installation and Operation Manual
9.3 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.
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

ATTENTION
INSTALLER:
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.
