Ideal Ignition Electrode 178126

The Ideal 178126 is an ignition electrode manufactured for Ideal Commercial appliances. It sits in the combustion path and produces the spark that lights the burner at the start of each firing cycle, so the appliance can move from a call for heat to a stable flame. It is listed against the alternative number 9051211 and is used across the Ideal Commercial Imax XEL range.

• The appliance attempts to fire but does not light, or locks out shortly after the ignition sequence begins.
• Repeated ignition attempts with no flame established, often followed by a fault code on the controls.
• A visible spark tracking to earth rather than across the electrode gap, or an audible arcing noise at the burner.
• Cracking, crazing or heavy soot and carbon build-up on the electrode tip or its ceramic insulator.
• Intermittent ignition that becomes more frequent over time as the electrode tip erodes.

• Confirm the appliance model and serial number against the compatibility list, as the electrode is used across several Imax XEL outputs.
• Check the existing electrode against the alternative number 9051211 to make sure the correct item is being replaced.
• Inspect the ignition lead and any associated gasket or seal at the same time, as these are commonly disturbed during replacement.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
