Page 5

2 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, fire officials or authorities having jurisdiction about restrictions, installation inspection, and permits.

Heat & Glo gas inserts are designed for recessed installa- tions into solid fuel masonry or factory built non-combustible fireplaces 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 qualified professionals. Hearth & Home Technologies recommends that NFI or CSIA certified professionals, or technicians under the direction of certi- fied professionals, conduct a minimum of a NFPA 211 Level 2 inspection of the chimney.

•Replace component parts of the chimney and fireplace as specified 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 fireplace size. See Section 3.A.

•Gas supply piping.

•Electrical wiring.

•Finishing details.

•Existing mantel, mantel legs and wall projection loca- tions. See Section 3.C.

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