The Andrews Water Heaters part is based near the electrodes. Usually, there are two types of electrodes, ignition electrodes and flame-sensing electrodes. The ignition electrode is responsible for creating the spark that starts off combustion within the burner. The flame sensing electrodes are responsible for monitoring if there is a flame present in the burner.
