SKJ72MT
The NORITZ SKJ72MT Ignition Plug W/Gasket initiates ignition by producing the electrical spark required to ignite the gas air mixture at the burner assembly. Its ignition electrode receives high-voltage energy from the ignition circuit and creates a spark across the specified ignition gap. Installed at the burner ignition in HVAC systems, the plug positions the electrode near the fuel-air mixture while the included gasket seals the mounting interface. The gasket maintains the required seal between the plug and its mounting surface during combustion. This ignition arrangement establishes the spark required to initiate combustion during the equipment's startup sequence.
