for heat unless the steamer will not be in use for an
extended period. If the pilot flame goes out, wait 5
minutes before relighting.
Main Burners (Gas Boilers). The main burners heat
the water in the boiler to generate steam.
Combination Control Valve (Gas Boilers). This gas
solenoid valve opens to allow gas flow when a call for
heat is made and also regulates the manifold gas
pressure.
Pressure Regulating Valve (Direct & Regenerated
Steam).
This valve regulates the manifold steam
pressure between 10-12 psi.
Magnetic Contactor (Electric Boilers). This
contactor, when energized, supplies power to the
electric heating elements.
Heating Elements (Electric Boilers). These heat the
water in the boiler to generate steam.
Cooking Compartment Controls
The upper section of the steamer consists of two
separate cooking compartments. Each compartment
functions independently with its own set of controls.
Power is supplied to the controls only after the steam
pressure rises above 3 psi to close the compartment
pressure switch. The switch remains closed as long
as steam pressure stays above 3 psi but will open if
the pressure drops below that setting.
Ready Light (Green) (Fig. 7). When lit, indicates
steamer is ready to cook.
Cooking Light (Red). When lit, indicates steamer is
in a cooking cycle.
Cooking Timer. Used to set desired cooking cycle
time between 0-60 minutes. When a timer is set, the
steam supply solenoid valve is energized to allow
steam into the cooking compartment but only after the
boiler has reached its operating pressure. Also,
energizes the buzzer when time expires.

Buzzer (Fig. 8). This signals end of a cook cycle, must
be turned off manually.
Door Switch. The door switch removes electrical
power to the timer.
Steam Solenoid Valve. This valve, when energized,
opens to allow steam into the cooking compartment
(normally closed valve).
Compartment Pressure Switch. This switch
supplies power to the controls only after the steam
pressure rises above 2.3 psi to close the compartment
pressure switch. The switch remains closed as long
as steam pressure stays above 2.3 psi but will open if
the pressure drops below that setting.
Manifold Pressure Gauge. This gauge indicates the
amount of steam pressure in manifold. The intake
shut-off valve should be adjusted so manifold
pressure remains at 9 psi with both compartments on.
Intake Shut-Off Valve. This valve is the main steam
supply shut-off from the boiler to the steam supply
manifold. This valve should NOT be left fully OPEN to
boiler steam supply. See INTAKE SHUT-OFF VALVE
ADJUSTMENT for additional information.
