13221 a EFFICIENCY RATING CERTIFIED ama Downflow/Horizontal Induced-Draft Gas Furnace GENERAL Before starting installation of this furnace, read these instructions carefully and completely. After installation is complete, remove the Energy Guide tag from the furnace. Also read the Procedures for Induced-Draft Gas-Fired Furnaces (packaged with furnace) for important information concerning combustion, venting, piping and other standard installation practices. Further reference can be made to the current edition of the American National Standard Z223.1 National Fuel Gas Code. The induced-draft vent system of this furnace is designed to operate at zero or negative pressure at the vent connector outlet. This furnace, therefore, complies with the National Fuel Gas Code (NFPA 54-1980 or ANSI Z223.1-1980), Part 7.14.3.b. This furnace is also listed by AGA for use with the type B1 gas vent, as described in the National Fuel Gas Code, Part 7.3.2. Each furnace is shipped from the factory completely assembled with multispeed direct-drive blower, and wired ready for indoor heating installation. All sizes feature a blower control center with easy-to-read low-voltage terminal strip to ensure proper connections. The output capacity and any representations of efficiency for this product are based on standard Department of Energy test procedures. The installed operation may vary, depending on installation, weather and other factors. ( \l NON Doiu'i n Mill!
