INSTALLATION & SERVICE CONNECTIONS
SECTION 2: MODELS: GC-2 & GC-3
Steamers are made of two sections, the Cooker and the Cabinet. These Steamers are
intended for use in commercial establishments. They are floor supported, are steam
heated and incorporate steel enclosures to contain live electrical parts.
Gas, Power, hot and cold water, must be supplied to these Steamers. Refer to Section 1,
Service Connections.
The Cooker consists of two or three compartments and is the upper portion of the Steamer. Each
compartment is provided with its own Solenoids, Interlock Switches, Timer, Pilot Light, Operating
Handle and Door. When a compartment is off, or de-energized, the Exhaust Solenoid Valve is
open and the inlet Steam Solenoid Valve is closed. Pans, containing food properly portioned, are
placed into guided racks or unto wire shelves provided in each compartment. When the door is
closed, the Timer dialed and the Operating Handle is pulled out to the locked position, (which also
locks the door and engages the Interlock Switches), the valves are energized. Steam reduced to
maximum 6 psi pressure by the Pressure Regulating Valve will then be permitted to enter the
compartment but not exit. Air, captured in the sealed compartment is allowed to exhaust through
the Compartment Vent which will close at approximately 180°F, whence the compartment becomes
an entirely sealed chamber. The duration of the cooking cycle is controlled by the Timer and when
desired time has elapsed. Timer will read '0' and will set off an audible Buzzer and de-energize
valves. Buzzer must be silenced by releasing the Operating Handle and presumably door opened
to remove cooked food. -
The Cabinet is the lower portion of the Steamer and contains components which control the
functioning of the Gas Boiler. A switch located on the front face of the Generator Control Box, when
turned ON will provide power for the appliance and also initiate the Gas Burners to maintain steam
generation in the boiler which in turn supplies steam to the compartment.
The Gas Boiler is designed to ASME Code and approved as a steam heating boiler restricted
to operate at pressures not to exceed 15 psi and the burner system is UL tested and Certified.
Refer to Periodic Maintenance, Section 4, for detailed version of components and controls.
