A permit may be required for installations, final approval is
contingent of the authority having local jurisdiction. Consult
insurance carrier, local building, fire officials or authorities
having jurisdiction about restrictions, installation inspection,
and permits.
Inspect the existing fireplace and chimney for any damage
or flaws such as burnouts, metal or refectory warping.
Inspection to a minimum of
NFPA 211
Level II is
recommended. All repairs must be made prior to installing
an insert. The fireplace must be structurally sound and be
able to support the weight of the solid-fuel insert
The factory-built chimney must be listed per
UL 127 or
ULC 610-M87
for all installations. Install thermal protection
per this appliance listing requirements.
A full height 6 inch diameter stainless steel full height
listed chimney liner must be installed meeting type HT
(2100°F) requirements per
UL 1777 (USA) or ULC S635
with “0” clearance to masonry (Canada). The full liner must
be attached to the insert flue collar and to the top of the
existing chimney.
The flue liner top support attachment must not reduce the
air flow for the existing air-cooled chimney system. Re-
install original factory-built chimney cap only; see section
on
Prefabricated Metal Chimney

To prevent room air passage to the chimney cavity of the
fireplace, seal either the damper area around the chimney
liner or the insert surround. Circulating air chamber (i.e. in a
steel fireplace liner or metal hearth circulatory) may not be
blocked. The air flow within and around the fireplace shall
not be altered, blocked by the installation of the insert. (i.e.
no louvers or cooling air inlet or outlet ports may be blocked
by the insert or the insert surround.
