6.8 Electrode

All burners are equipped with continuous electronic spark electrodes to ensure flame is on at all
times during operation.
Continuous sparking is intended to remain energized until its corresponding ignition control
module senses flame current. Electrical spark generation is then shut off until flame current is no
longer sensed. Refer to the wiring diagrams for proper ignition wire connections to the ignition
module.
Spark gap: min 0.125"(1/8"), and max 0.160"(5/32").
Visual inspection is often sufficient to check for a faulty electrode. Check for bent, damaged
electrodes or cracked ceramics on the electrodes.
