Beckett BurnerParts: 5781 Electrode Assembly Kit (cat#2611)
The electrode provides the elctric spark to ignite the fuel nozzle. The electrode is a metal rod that is threaded on one end and bent or curved on the other end. Two of these rods are paired and curved toward each other so that electrical arcing will occur at and only between the tips of the roda. The electroded are inserted through a ceramic insulator . the insulator prevents arcing between the back portions of the rod and other metal components.
