Lennox’s discontinued GCS16 air conditioner, first introduced in 1989, is a combination packaged gas heat/dx cool unit for residential and light commercial use. It is available in sizes ranging from 2 to 5 tons for residential applications or 6 to 25 tons for commercial use. The unit can be installed on rooftops or on the side of buildings, with discharge air directed from beneath or horizontally. The GCS16 has an AFUE of up to 80 percent and a SEER of up to 12.70. The unit uses R-22 refrigerant.
Lennox manufactures cabinets from heavy gauge galvanized steel and coats them with an electrostatically bonded powder enamel paint. The internal components are accessed via removable cabinet panels. The control box’s placement and removable aluminized steel burners were designed to be serviced easily.
The GCS16’s heat exchanger is made with aluminized steel, providing resistance to corrosion and rusting. The curved, rounded shape of the heating surface was designed for improved heat transfer, and direct spark ignition improves efficiency by sparking intermittently.
The Lennox GCS16 is equipped with fan guards made with corrosion-resistant PVC coated steel wire. GCS16 models have either one or two fans, and each unit’s motor is permanently lubricated and protected from overload.
Both the residential and commercial models of the GCS16 can accept various thermostat control systems. Several accessories are available, including the economizer, warm-up kit and Honeywell control products. The cabinet has a low voltage terminal strip enabling field wiring.
