Henny Penny OFG-390 High Limit, Ignition Modules, Spark Ignitors, Flame Sensors, Airflow Switch

	Model OFG- 390
3-1. OPERATING COMPONENTS
(Continued)
High Limit	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

Figure 3-1
Ignition Modules	The two ignition modules send 24 volts to the gas control valve and
	high voltage to the ignitors
Spark 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
Flame Sensors	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
Gas Control Valve	Adual controller, in which, one side of the valve controls the pilot
	light and the other side controls the main burner
Airflow Switch	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.
Blower	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
Air Valve	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
