The Goodman 10716003 Natural Gas Orifice is a genuine OEM brass burner spud for the Amana/Goodman AMH81405DNAB 80% AFUE gas furnace. The orifice threads into the manifold and meters the exact volume of natural gas delivered to each in-shot burner. Its precision-drilled bore is what sets the furnace's input BTU rating, so using the factory-specified orifice is essential for correct firing rate, clean combustion, and rated efficiency.
Orifice bore diameter is drilled to a specific number for the burner and altitude the furnace was rated for. The OEM 10716003 guarantees the correct metering; a generic or mis-drilled orifice can over- or under-fire the furnace, causing sooting, poor efficiency, or a safety hazard. Never substitute an unverified bore size.
Easy (2/5). Shut off the gas, back the orifice out of the manifold with a nut driver, and thread in the replacement — do not over-tighten the soft brass. Verify no gas leaks with soap solution before firing. Confirm the correct part for LP conversions or high-altitude derating.
