Riello G20 electrodes are 220 mm ignition electrodes for the Riello G20 burner.
Set the gap as the manual shows.
What are riello g20 electrodes?
Burners need a spark to light and a sensor to prove the flame. Ignition electrodes carry the spark from the transformer into the fuel spray. Photocells such as the Siemens QRB series see the light of an oil flame, and UV sensors such as the QRA2 see ultraviolet light from the flame.
If the sensor cannot see the flame, the control box locks the burner out. Therefore, keep sensors clean and use the type the control box expects.
