Indirect Gas Fired Unit Installations

Units are listed for installation in the United States and Canada.

•Installation of gas fired duct furnaces must conform with local building codes. In the absence of local codes, installation must conform to the National Fuel Gas code, ANSI Z223.1 or in Canada, CAN/ CGA-B149 installation codes.

•All electrical wiring must be in accordance with the regulation of the National Electrical Code, ANSI/ NFPA 70.

•Unit is approved for installation downstream from refrigeration units. In these conditions, condensate could form in the duct furnace and provision must be made to dispose of the condensate.

Clearance to combustibles is defined as the minimum distance required between the heater and adjacent combustible surfaces to ensure the adjacent surface’s temperature does not exceed 90 degrees above the ambient temperature.

*Reference venting guidelines for combustion blower clearances.

Recommended Minimum Service Clearances

42 inches (1067 mm) on the

and less

controls side of the unit

Clearances for component removal (such as evaporative cooler media) should be 6 in. wider than the width of the module itself.
