7. SEQUENCE OF OPERATION
7.1 Power On
• When the Clamshell® is plugged in, 220 Volts is applied to the blower motor. The Clamshell® is
designed to have a constantly running blower motor.
• The air switch then senses the blower motor, closes, and applies the 220 Volts to a 24 VAC transformer.
• The transformer then supplies 24 VAC to the tilt switch, and to the automatic cutoff valve.
• The 24 VAC to the automatic cutoff valve opens the gas valve to the griddle/charbroiler, thus allowing the
base unit to operate.
• When the Clamshell® is lowered, the tilt switch allows 24 VAC to go to the spark module.
• The spark module then supplies 24 VAC to open the Clamshell® gas valve, and high voltage to the spark
igniter.
• When the burner ignites, the sense probe senses the flame is ignited and the spark module turns off the high
voltage to the spark igniter.
• When the Clamshell® is raised the tilt switch opens the 24 VAC to the spark module, which removes the
24 VAC to the gas valve, turning off the Clamshell®.
