Energy Guide tag may be removed from furnace when installation is complete. G efficiency RATING certified ama INTRODUCTION Before installing the furnace, refer to Procedures for Gas-Fired Furnaces (packaged with the equipment) for information concerning combustion, venting, piping, and other standard installation practices. Further reference is made to the current edition of the National Fuel Gas Code, NFPA54-1984/ ANSI Z223.1-1984. Each furnace is shipped from the factory completely assembled with multispeed direct-drive blower and wired ready for counterflow indoor heating installation only. All sizes feature a printed-circuit board control center with easy-to-read, low-voltage terminal strip to ensure proper connections. A CAUTION Do not install furnace in a corrosive or contaminated atmosphere. Make sure all combustion and circulating air requirements listed in Procedures for Gas-Fired Furnaces are adhered to, in addition to all local codes and ordinances. A CAUTION Do not block openings in front of furnace or on furnace top along side vent pipe. These openings provide air for combustion and ventilation. Never store anything on or in contact with furnace, such as: aerosol cans, rags, brooms and mops, cleaning tools and aids, powders, bleaches, waxes, plastic items, gasoline, kerosene, lighter fluids, cleaning fluids, thinners, painting compounds or paper products. The design of the counterflow gas-fired furnace is A.G.A certified for installation on combustible flooring (with optional floor base), in alcoves, basements, closets or utility rooms. This furnace line is not A.G.A. certified for installation in a mobile home, recreation vehicle, or outdoors Installation Procedures: Page Inspection......................................* Location, Ventilation and Air for Combustion................................* Gas Piping.....................................* Venting........................................* Supply-Air Plenum Installation...................1 Electrical Connections...........................3 Sequence of Operation...........................4 Filter Arrangement..............................5 Start-Up and Adjustment.........................6 Care and Maintenance...........................6 *Refer to appropiiate sections in Pioceduies foi Gas-Fired Furnaces packed with this furnace For accessory installation details, refer to applicable installation literature.
