The Vulcan Hart 00-944255 Rotary Ignitor is a three-pole ignition control used with compatible gas griddles and cooking equipment. Its rotary mechanism produces the spark needed to initiate burner ignition when the control is turned. The unit features three spark outputs with 1/8-inch round recessed pins, making these specifications useful when identifying the correct ignition part for service work. It is associated with Vulcan Hart equipment as well as certain Imperial and Jade Range.
