Lennox 49M85 Spark Electrode Ignitor

The Lennox 49M85 Spark Electrode Ignitor is a high-voltage element that is used in the HVAC systems to start combustion in gas-fired equipment. It works by producing a controlled spark upon the electrode tip when excited which forms the ignition source needed to start the gas flame. It requires the location of the ignitor in the combustion chamber and placing it in line with the burner assembly as per the system requirements. The design facilitates stable flame development, sound ignition operation, and similar start-up operation when the electrode is used under normal heating conditions.
