Riello Electrodes Group 3000650

The Riello Electrodes Group is a burner ignition component supplied by Riello for use in Riello burner assemblies. The electrodes sit in the ignition circuit and provide the spark gap that lights the fuel-air mixture at start-up. It is listed under Riello burner spares and carries the part number 3000650.

• The burner fails to ignite on start-up, with the control box locking out.
• No visible spark at the electrode tips when the ignition circuit is tested.
• Electrode tips are eroded, rounded or bridged with carbon deposits.
• Cracked or brittle ceramic insulation on the electrode bodies.
• Intermittent ignition, with the burner lighting on some attempts and locking out on others.

• Confirm the burner model and serial details against the Riello parts list for your appliance.
• Check the existing electrode assembly and its mounting arrangement match the part number 3000650.
• Inspect the ignition leads and control box at the same time, as lockout faults are not always caused by the electrodes alone.
• Verify the electrode gap and positioning against the burner manufacturer's settings before fitting.
