What it is
The Riello block electrode (3005721) is an ignition component used in Riello oil burner assemblies, referenced in the product name against the R40 and Mectron 2/3 burner ranges. It forms part of the burner's ignition circuit, where the electrode establishes the spark that lights the oil and air mixture at start-up. It is listed here as an oil burner spare for boiler applications.
Before you order
- Confirm the burner model on the appliance matches the R40 or Mectron 2/3 references given here.
- Check the part number stamped or printed on the existing electrode against 3005721.
- Examine the electrode block and its mounting arrangement on the burner before ordering, as electrode assemblies vary between burner builds.
- If the burner has been serviced recently, confirm which ignition components were replaced to avoid duplicate ordering.
