The Vokera ignition electrode and lead. There are two kinds of electrodes, ignition electrodes and flame-sensing electrodes. The ignition electrode generates the spark that ignites combustion within the burner. The flame-sensing electrodes oversee ensuring that there is a flame present in the burner. This is a critical task that ensures the boiler does not continue to supply gas while there is no flame present.
Comes with lead, seal and screws
