B. Design and Installation Considerations
Heatilator gas inserts are designed for installations into
solid fuel masonry or factory built fi replaces that have
been installed in accordance with the National, Provin-
cial, State and local building codes. Fireplaces are to be
constructed of non-combustible materials and, in the ab-
sence of local or regional codes, meet criteria of NFPA
211. No additional outside air source is required.
Installation MUST comply with local, regional, state and na-
tional codes and regulations. Consult insurance carrier, local
building inspector, fi re offi cials or authorities having jurisdic-
tion over restrictions, installation inspection and permits.
Prior to installing the gas insert:
• Have the chimney and adjacent structure inspected
and cleaned by qualifi ed professionals. Hearth & Home
Technologies recommends that NFI or CSIA certifi ed
professionals, or technicians under the direction of certi-
fi ed professionals, conduct a minimum of a NFPA 211
Level 2 inspection of the chimney.
• Replace component parts of the chimney and fi replace
as specifi ed by the professionals.
• Ensure combustible mantel and surround clearances
comply with applicable codes and regulations for solid-
fuel fi replaces. In the absence of local or regional codes,
refer to NFPA 211.
• Ensure all joints are properly engaged and the chimney
is properly secured.
• Minimum fi replace size. See Section 5.A.
• Gas supply piping requirements.
• Electrical wiring requirements.
• Finishing details.
• Whether optional accessories—devices such as a wall
switch or remote control—are desired.
D. Inspect Appliance and Components
• Carefully remove the appliance and components from
the packaging.
• The vent system components and decorative doors and
fronts may be shipped in separate packages.
• If packaged separately, the log set and appliance grate
must be installed.
• Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.
• Read all of the instructions before starting the instal-
lation. Follow these instructions carefully during the
installation to ensure maximum safety and benefi t.
