Ionisation Electrode

• 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 within the burner.
• The flame sensing electrodes are responsible for detecting whether there is a flame present in the burner. This is an important task and if the flame is not detected the boiler knows to re-attempt ignition.

It is recommended that only original Ariston spare parts are fitted to their boilers.
