FRONT PANEL CONTROLS
POWER SWITCH : ........................ This switch turns the main power to the unit on and off. It must be turned on to heat the
kettle. It should be turned off when the kettle will not be in use for long periods.
IGNITION LIGHT (GREEN) : ......... This light is on whenever the main burner gas is on.
COOKING LIGHT (RED) : ............. This light is on when the thermostat is calling for heat.
LOW WATER LIGHT (AMBER) : .. All kettles are supplied with sufficient distilled water in pressurized jacket. If at any time
the water level falls below that required for proper operation, the kettle will not heat and
this light will come on. See “Adding Water” in Service section.
THERMOSTAT : ............................. The thermostat selects the desired internal kettle operating temperature. The
thermostat must be set at a desired setting in order for the burner to ignite. Reference
Dial Setting table below.

PRESSURE GAUGE :.................... The pressure gauge indicates the internal operating pressure of the kettle. When
cold, the gauge should point to the green vacuum zone. If it does not, refer to
“Re-establishing Vacuum” section. Under normal operation with the kettle empty
(thermostat set at 10 or 275°F) the pressure should reach 30 psi. When loaded the
pressure may be considerably less.
SIGHT GLASS : ............................. The sight glass indicates the minimum and maximum water level within the kettle.
If water level falls below minimum level more distilled water should be added. See
“Adding Water” in Service section.
PRESSURE RELIEF VALVE : ....... The pressure relief valve is a safety device which prevents the internal kettle pressure
from exceeding 50 psi. It should never be tampered with.
