Description
The Noritz SKJ71VZ Ignition Plug with Gasket transfers high-voltage electrical discharge from the ignition module into the burner chamber of a tankless water heater, activating the gas-air mixture the moment a startup sequence activates. A molded sealant at the base creates a pressure-tight seal against the housing, containing combustion pressure without additional sealing compounds. The plug threads into a dedicated port on the burner body, torquing to the specified value through a standard wrench. Water heating appliances connected to HVAC systems count this plug as the final link in the ignition chain, where each electrical pulse initiates flame establishment under fluctuating gas pressure conditions.
