INSTALLATION
INSTALLATION IN TO A FACTORY BUILT (METAL) FIREPLACE
When installing into a factory built fi replace, the fi rebox must accept the insert without modifi cation other than re-
moving bolted or screwed together pieces such as smoke shelf/defl ectors, ash lips, screen or door tracks and damper
assemblies. These items must be reinstalled to restore the fi replace to its original operating condition if the insert is
removed and not replaced. The removal of any part must not alter the integrity of the listed fi replace in any way.
The factory built fi replace must be listed per UL 127. Installation must include a full height listed chimney liner meet-
ing type HT requirements (2100
o
F) per 1777 (U.S.). The liner must be securely attached to the insert fl ue col
lar and
the chimney top. The damper area must be sealed to prevent room air passage to chimney cavity.
Alteration of the fi replace in any manner is not permitted except with the following exceptions:
• External trim pieces, which do not affect the operation of the fi replace, may be removed proving they can be stored
on or within, the fi replace for re-assembly if the insert is removed.
• The fi replace damper may be removed to install the chimney liner.
Circulating air chambers, louvers or cooling air inlet or outlet ports (i.e. in a steel fi replace liner or metal heat circulator)
shall not be blocked.
Means must be provided for removal of the insert to clean the chimney fl ue.
A permanent metal warning label must be attached to the back wall of the fi replace opening stating the following:
• “This fi replace has been altered to accommodate a fi replace insert and should be inspected by a qualifi ed person
prior to re-use as a conventional fi replace.”
• This label is available upon request.
Final approval is contingent on the authority having jurisdiction.
