The Goodman 10716005 Natural Gas Orifice is a genuine OEM brass burner spud for ACES800804BXAA gas furnaces and compatible Goodman/Amana models. Threaded into the gas manifold, the orifice meters the precise amount of natural gas delivered to each in-shot burner, setting the firing rate and ensuring a clean, correctly sized flame. A worn, enlarged, or incorrectly drilled orifice causes over- or under-firing, sooting, and poor combustion efficiency. Using the factory-spec orifice keeps the furnace operating at its rated BTU input.
The genuine OEM Goodman orifice is drilled to the exact size required to deliver the rated input at the design manifold pressure. Generic or mis-drilled orifices alter the firing rate and can create dangerous combustion conditions. Orifice sizing is safety-critical — always use OEM and never re-drill a used spud.
Moderate (3/5). Shut off gas and power, remove the manifold or burner as needed, and unthread the old orifice with the correct nut driver. Thread the new orifice to spec (do not overtighten), then leak-check and verify manifold pressure. Recommended for an HVAC professional.
