The Goodman 10716005 Natural Gas Burner Orifice is a genuine OEM spud that meters the precise gas flow into each in-shot burner on ACEC800805CXAA gas furnaces. The orifice drill size sets the furnace's firing rate and BTU output, so using the correct factory orifice is essential for safe, efficient combustion. Damaged threads, a clogged port, or the wrong drill size can cause underfiring, sooting, or improper flame.
The OEM orifice is drilled to the exact size Goodman specifies for this furnace's input rating. Substituting an incorrect orifice changes the firing rate and can create a safety hazard. Always match the OEM part number for natural gas applications, and use the correct LP orifice if the furnace is converted.
Moderate (3/5). Shut off gas and power, remove the burners or manifold for access, then unthread the old orifice and install the new one. Leak-test all connections with soapy water afterward. If unsure, use a licensed technician.
