It includes the burner component positioned at the end of the burner tray, which ignites and sustains the flame used to heat the water supply. At 14 inches in length and fitted with a 37 orifice, this kit delivers the correct fuel metering and combustion geometry for the target appliance. Licensed plumbers and gas appliance technicians handle this type of repair when the existing burner shows erosion, clogging, or flame-pattern failure. The kit format means the critical hardware ships together, reducing the risk of mismatched components during a field repair.\u003c\/p\u003e\u003cp\u003eThis burner assembly is intended for natural gas-fired residential water heaters. The 14-inch length and 37 orifice size point to a specific heater configuration, so verifying the model number on the water heater data plate before ordering is essential. It is suited for service work where the original burner has degraded and a full burner replacement is required rather than a simple orifice swap.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNatural gas configuration with 37 orifice for precise fuel metering\u003c\/li\u003e\n\u003cli\u003e14-inch burner length matches the target heater combustion chamber\u003c\/li\u003e\n\u003cli\u003eKit format includes all required burner assembly components\u003c\/li\u003e\n\u003cli\u003eOEM-style replacement designed for direct installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement final burner assembly for AO SMITH natural gas water heaters requiring a 14-inch burner with a 37 orifice.

Before beginning work, shut off the gas supply at the isolation valve and allow the burner assembly to cool completely.
