This high temperature control senses the temperature of the short-
ening; if the temperature of the shortening exceeds 450°F
(230°C), this control will open and shut off the heat to the frypot;
when the temperature of the shortening drops to a safe operation
limit, the control must be manually reset by pressing the red reset
button, located under the control panel, in the front of the fryer
The two ignition modules send 24 volts to the gas control valve and
high voltage to the ignitors
When the pilots are being lit, the spark ignitors are electrically
energized and the tip of the ignitors spark to ignite the pilot lights
Sense the pilot lights when the power switch is turned on; if the
pilots go out, or do not light, the flame sensors shutd the gas off, via
the modules
A dual controller, in which, one side of the valve controls the pilot
light and the other side controls the main burner
Senses the flow of air coming from the blower; if the airflow is
reduced below a set amount, the switch cuts power to the gas
control valve, which shuts down the burners
To avoid property damage, do not tamper with or disas-
semble this component. It is set and sealed form the
factory and is not to be adjusted.
Adds the proper amount of air into the burner tubes, so an efficient
combustion takes place, and also, pulls the flue gases out to the flue
Pumps air into the shortening, periodically, to keep the shortening at
a uniform temperature; this only functions when the unit has been
sitting idle for a period of time and when heating up from a cold
start
