• The ignitor, sometimes called spark generator. Sends an electronic pulse when activated (button pushed, knob turned).
   
• A ceramic and metal electrode that delivers the spark that ignites the gas, much like an automobile spark splug.
   
• Wires that connect the spark generator to the electrodes. The connectors on each end of the wire must be of the same type and opposite sex as the connector to which it is to be atached.

• Outlets are typically male round connectors
• Require connecting wire with female round connector
• Does not require a battery

• Outlets are typically male round connectors
• Require connecting wire with female round connector
• Sometimes have an extra flat male spade connector grounding lug that can also power a side burner
• Does not require a battery

• Outlets are typically flat male spade connectors
• Require connecting wire with female spade connector
• Require a battery (usually AA or AAA, although there are some 9V systems)
• AA Electronic ignitors usually require a slightly larger
  mounting hole than the AAA ignitors

There are a variety of electrodes, but they all do the same thing: provide the spark that ignites the gas when the ignitor button is depressed, or the knob is turned. They're the spark plug of the grill. They may be burner-mounted, casting-mounted, frame-mounted, with or without a collector box, with or without integral wire.

If the electrode has an integral wire, you don't have to worry about getting the connector right. If not, make sure the connecting wire (wire from the ignitor) is the same connector type (round or flat spade) on the end that connects to the electrode. We carry some short wires designed to convert one type to the other.

Ignitors (spark generators) are connected to electrodes with a wire, usually one wire for each electrode. The wire is integral on some electrodes (built in), and separate on others.
