The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud that meters natural gas into the in-shot burners of Goodman/Amana VMES800804BXAA 80% AFUE furnaces. The orifice's precisely drilled bore sets the fuel flow rate that pairs with the burner venturi to produce the correct air-fuel ratio. A damaged, plugged, or wrong-size orifice causes lazy flames, sooting, poor efficiency, or delayed ignition. Use the drill size specified for your altitude and manifold pressure.
Genuine OEM 10716005 is machined to Goodman's exact orifice drill size and thread, delivering the rated BTU input at spec manifold pressure. A generic or mis-sized orifice changes the firing rate and flame quality, risking incomplete combustion and CO. Because gas metering is safety-critical, OEM is the recommended choice — and always confirm the correct orifice size for your natural-gas application and elevation.
Plan on 30–45 minutes. Shut off the gas and power, remove the manifold, unthread the old orifice, and install the correct replacement. Gas metering directly affects combustion safety — after installation a licensed HVAC technician should verify manifold pressure, flame appearance, and CO levels. Shut off the gas valve before servicing.
