line of upflow gas furnaces are designed for utility

rooms, closets, alcoves, or attics. Because of the low-

profile 34 inch [864 mm] height, the upflow model can also be used to satisfy most applications that traditionally call for a horizontal furnace.

• Two stages of operation to save energy and maintain optimal comfort level.

• Furnace operates at 70% capacity for low-heat and 100% capacity for high-heat.

• Compatible with single or two-stage thermostat. (For optimal performance two-stage thermostat recommended.)

• Heat exchanger is constructed of aluminized steel for maximum corrosion resistance and thermal fatigue reliability.

• Low profile “34 inch” design is lighter and easier to handle and leaves room for optional accessories.

• Left or right side gas, electric, and condensate drainage connections on upflow models.

• Integrated control board manages all operational functions and provides hookups for humidifier and electronic air cleaner.

• An insulated blower compartment, a slow-opening gas valve and a specially designed inducer system make it one of the quietest furnaces on the market today.

• Pre-paint galvanized steel cabinet.

• Molded permanent filters.

• Optional indoor or outdoor combustion air. In addition, combustion air may be piped to either the top or side of the cabinet on all upflow models. A special molded fitting is provided to ease installation.

• Transformer and control fuse protection.

• Solid bottom is standard.

• Control board diagnostics.

• A variety of cooling coils and plenums designed to use with the Classic 90 Plus gas furnaces are available as optional accessories for air conditioning models.
