2100-I & 3100-I FIREPLACE INSERT
Page 19
March 1999
NOTE:
Installation into fireplaces without a permit will void the listing.
The factory built chimney must be listed per UL 127 (US) or ULC S610 (Canada), and
meet the type HT requirements of UL 103 (US) or ULC S629M (Canada). Factory built fireplace
chimneys tested to UL 127-1998 are tested to the same criteria as UL 103 HT requirements. If the
chimney is not listed as meeting HT requirements (factory built fireplaces tested prior to 1988), a
full height listed chimney liner must be installed from the appliance flue collar to the chimney
top. The liner must meet type HT requirements (2100ºF) per UL 1777 (US) or ULC S635 (Canada).
The liner must be securely attached to the insert flue collar and the chimney top. To prevent room
air passage to the chimney cavity of the fireplace, seal either the damper area around the chimney
liner with high temperature sealant or the fireplace front with fiberglass batting.
The fireplace must not be altered, except that the damper may be removed to accommo-
date a direct-connect starter pipe or chimney liner, and external trim pieces which do not affect
the operation of the fireplace may be removed providing they can be stored on or within the
fireplace for reassembly if the insert is removed. The permanent metal warning label provided
must be attached to the back of the fireplace, stating that the fireplace may have been altered to
accommodate the insert, and must be returned to original condition for use as a conventional
fireplace.
The air flow within and around the fireplace shall not be altered by the installation of the
insert (no louvers or cooling air inlet or outlet ports blocked). The circulating air chambers (in a
steel fireplace liner or metal heat circulator) shall be blocked.
If the hearth extension is lower than the fireplace opening, the portion of the insert extend-
ing onto the hearth must be supported. Manufacturer designed support kits can be ordered by size
(see page 9).
Final approval of this installation type is contingent upon the authority having jurisdic-
tion.
