Vaillant 193590 ignition cable

This Vaillant ignition cable is a used in the electrodes of ecoTEC VU (condensing), ecoTEC VUW (condensing) and ecoTEC VUI (condensing) boilers. An ignition (spark) electrode causes the spark that begins combustion within the burner while flame sensing electrodes are responsible for checking if there is a flame present in the burner to make sure that the boiler doesn't keep supplying gas without a flame.
