•The original factory-built zero clearance fi replace chim-
ney cap must be re-installed after installing the approved
chimney liner meeting type UL 103 HT requirements

•If the chimney is not listed as meeting HT requirements,
or if the factory built fi replace was tested prior to 1998, a
full height listed chimney liner must be installed from the
appliance fl ue collar to the chimney top.
•The liner must be securely attached to the insert fl ue collar
and the chimney top.
•The

fl ow of the factory-built zero-clearance fi replace
system must not be altered. The fl ue liner top support
attachment must not reduce the air fl ow for the existing
air-cooled chimney system.
•No dilution air is allowed to enter the chimney.

this cannot be accomplished, it will be necessary to
remove the damper.
2. Seal damper area of chimney around chimney
connector with a high temperature sealant or seal
insert against the face of the fi replace.
3. Both methods must be removable and replaceable
