Description
The Patterson-Kelley 23-0000-0127 P-K Ignition Electrode Ground is a neutralizing element that completes the ignition circuit in a gas-fired burner. It works as the fixed reference point from which the spark electrode generates a high-voltage arc across a precisely set gap to ignite the gas-air mixture at the burner head. The gap distance between the two electrodes directly determines how reliably the arc forms on each ignition attempt. Within HVAC systems, this electrode sits at the burner of a compatible boiler or water heater, where a consistent flue reference prevents misfires and ensures the burner lights cleanly.
