Description

Product Information:
Usually, there are two types of electrodes, Ignition electrodes and flame sensing electrodes. The Ignition electrode is responsible for causing the spark that begins combustion. The flame-sensing electrodes are responsible for checking if there is a flame present in the burner. This is an important safety device that makes sure the boiler isn’t still supplying gas without a flame.
