The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud sized for the ADSH800804BXAC gas furnace. The orifice meters the precise volume of natural gas delivered to each burner, setting the furnace's rated BTU input and ensuring a clean, stable flame. A correctly sized orifice is essential for safe, efficient combustion — an over- or under-drilled hole leads to sooting, poor flame carryover, delayed ignition, or reduced heat output.
OEM vs. Generic: The OEM 10716005 is precision-drilled to Goodman's specification for this furnace at standard manifold pressure. Generic orifices are frequently sold by nominal drill size only and can vary enough to shift the firing rate outside spec, causing incomplete combustion or elevated CO. For a combustion component, the factory-matched orifice is the safest choice.
Install difficulty: Moderate (2/5). Shut off gas and power, remove the burner assembly or manifold, and thread the orifice into place — do not overtighten the brass spud. After installation, verify manifold pressure and inspect flame quality; a combustion analysis is recommended. This orifice is for natural gas only; do not use on an LP-configured furnace without the correct LP orifice and conversion kit.
