This kit includes the final burner component fitted with a 34 orifice, delivering properly metered gas flow for consistent ignition and combustion performance. It is a direct service part intended for use in natural gas-fired water heater applications and is typically installed by licensed plumbers or gas appliance technicians during burner replacement or combustion system service.\u003c\/p\u003e\n\u003cp\u003eThis burner assembly kit is suited for heating applications where the original final burner has worn, corroded, or failed. The 18-inch size and 34 orifice specification make it a fit-specific replacement rather than a universal part.
