How to Replace the Ignition Electrode on a Ideal Vogue Gen2 32 (UK)

Step-by-step UK guide to replacing the spark / ionisation electrode on a Ideal Vogue Gen2 32. Part numbers, torques, commissioning.

Ideal

The part

Renew the ignition and flame-sense electrodes on Ideal Vogue Gen2 32 when you get F27 / EA / L2 flame-detection faults after a clean burn.

Isolate safely

Both electrodes on Ideal Vogue Gen2 32 use ceramic insulators — never re-use if chipped.

Fit and commission

Set the spark gap to 3.5–4.0 mm and the ionisation gap so the tip sits 4–5 mm above the burner surface.

Recommission checklist

Refill the Ideal Vogue Gen2 32 to 1.2 bar cold. Bleed high-point radiators and the internal AAV.

Run a full flue-gas analysis after 15 minutes. Log the reading against the OEM commissioning envelope in the Benchmark book.
