Ideal Ignition Electrode Kit 170919

The Ideal ignition electrode kit, part number 170919, is a replacement ignition electrode assembly for Ideal gas boilers. It sits in the combustion area and delivers the spark that lights the burner when there is a call for heat. This is an Ideal Spares component listed for the Classic M and Icos M appliance families.

• The boiler attempts to light but the burner does not fire, or fires intermittently.
• Repeated lockouts on start-up, often after the fan and gas valve have run through their sequence.
• No visible spark at the electrode when the ignition sequence is observed.
• Cracking, crazing or heavy sooting on the electrode body or its ceramic insulator.
• Arcing or a snapping noise from the combustion area instead of a clean spark at the burner.

• Confirm the appliance GC number against the compatibility list, as the same model name can appear across several build variants.
• Note the alternative part number 1177949 when cross-referencing an existing electrode or an old stock label.
• Inspect the electrode lead, gasket and sealing washer at the same time, as these are disturbed during replacement.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
