The Goodman 10716005 Natural Gas Orifice (burner spud) is a genuine OEM part for the Goodman/Amana ADSH800403AXAB gas furnace and compatible 80% AFUE models. The orifice is the precisely machined brass nozzle that meters natural gas into each burner, setting the firing rate and air/fuel mixture. Its drilled bore size is matched to the furnace's rated input BTU and natural-gas supply pressure, so using the correct OEM orifice is critical for clean, efficient, and safe combustion.
Orifice bore diameter is the single most important spec on this part — a few thousandths of an inch changes the BTU input and flame quality. The genuine Goodman 10716005 is drilled to the manufacturer's exact specification for this model. Generic or mis-sized orifices can cause sooting, delayed ignition, or unsafe over-firing, so OEM is strongly recommended.
Shut off gas and power before service. The orifice threads into the manifold/burner rail and is removed with a deep socket or wrench; replace each in its original burner position. Because this part affects combustion, we recommend a licensed technician verify manifold gas pressure and inspect the flame after installation. Do not substitute an LP/propane orifice — confirm the fuel type matches your supply.
