Flame Recognition

The re-igniter module features flame sensing circuitry for 

each burner. Any active igniter switch applies 120VAC 

to the flame sense circuitry and the sense electrode for 

the appropriate burner. With a flame present, the module 

reads the direct current to ground that passes through 

the flame. If a gas valve is engaged, and the re-igniter 

does not read enough current (0.2µA) on the selected 

burner; the module will begin sparking on all burners 

until flame is established. There is a built in sparking 

delay of approximately 1 second to allow for low or 

waivering flame conditions.

Spark System 

The spark ignition system consists of a 4+0 / 6+0 

re-igniter module, spark igniters, and an igniter micro 

switch harness. Switches are located on the stem of 

each gas valve. Turning a surface burner knob past the 

OFF postion, closes the igniter micro switch. The closed 

circuit signals the reigniter module to begin sparking 

on all burners until flame is detected on the burner 

presently engaged.
The spark module sends approximately 1 spark per 

second to the spark igniters.
