Kettle 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.
(GREED) IGNITION LIGHT
This light is on whenever the main burner gas is on.
(RED) COOKING LIGHT
This light is on when the thermostat is calling for heat.
(AMBER) LOW WATER LIGHT
All kettles are supplied with sufficient distilled water in
pressurized jacket. If at any time the water level falls be-
low 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 operat-
ing temperature. The thermostat must be set at a desired
setting in order for the burner to ignite.

PRESSURE GAUGE
The pressure gauge indicates the internal operating pres-
sure of the kettle. When cold, the gauge should point to
the green vacuum zone. If it does not, refer to “Re-estab-
lishing 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 wa-
ter level within the kettle. If water level falls below mini-
mum 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 pre-
vents the internal kettle pressure from exceeding 50 psi.
It should never be tampered with.
