The Ideal ignition lead is part of the Esprit 2, Icos, Istor, Mexico, Esprit, Evo, Isar and Elise 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.
