SAUNIER DUVAL 0020018434 ELECTRODE+ SCREW + GASKET

Usually, there are two types of electrode, Ignition electrodes and flame sensing electrodes. The Ignition electrode is responsible for causing the spark that starts off combustion. The flame sensing electrodes are responsible for monitoring whether 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.

This part is present in 7 different boilers in the Saunier Duval range including the Saunier Duval ULTRACOM 2 12 , ULTRACOM 2 18 , ULTRACOM 2 30 , ULTRACOM 2 24 , ULTRACOM 2 30 .
