Getting Started

A. Design and Installation Considerations

Heat & Glo direct vent gas appliances are designed to
operate with all combustion air siphoned from outside of
the building and all exhaust gases expelled to the outside.
No additional outside air source is required.

CAUTION

Check building codes prior to installation.

• Installation MUST comply with local, regional, state and
national codes and regulations.

• Consult insurance carrier, local building, fi re offi cials or
authorities having jurisdiction about restrictions, installation
inspection, and permits.

Heat & Glo gas inserts are designed for recessed installa­tions into solid fuel masonry or factory built non-combustible
fi replaces that have been installed in accordance with the
National, Provincial, State and local building codes.

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 certi­fi 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 all joints are properly engaged and the chimney
is properly secured.

When planning an appliance installation, it’s necessary to
determine the following information before installing:

• Minimum fi replace size. See Section 3.A.

• Gas supply piping.

• Electrical wiring.

• Finishing details.

• Existing mantel projections. See Section 10.

• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
