Nordyne Intertherm 661030 30 Natural Gas Orifice

Product Description

The Nordyne Intertherm 661030 is a Number 30 natural gas orifice designed for use in residential and light commercial gas furnaces. This orifice is a critical component in any gas heating system. It controls the flow of natural gas from the manifold into the burner. The size of the orifice determines how much fuel reaches the burner, which directly affects combustion efficiency and heat output. A properly sized orifice ensures clean, complete combustion, reducing the risk of carbon monoxide production and improving overall furnace performance. HVAC technicians rely on correctly matched orifices when servicing or replacing gas valves, manifolds, or burner assemblies. Using the wrong orifice size can result in poor flame characteristics, yellow tipping, sooting, or unsafe operating conditions. The Nordyne Intertherm 661030 is built to factory specifications for compatible Nordyne, Intertherm, Miller, and related brand furnace units. It is a direct OEM replacement part, ensuring a proper fit without modification. When performing a natural gas conversion, a tune-up, or a burner section repair, having the correct Number 30 orifice on hand is essential. This part is commonly stocked by HVAC supply houses and used by service technicians in the field for quick, reliable repairs. Nordyne is a well-established manufacturer of heating and cooling equipment, and their OEM replacement parts are held to consistent quality standards. Whether you are replacing a damaged orifice, performing routine maintenance, or completing a full burner assembly service, the 661030 delivers reliable performance in natural gas applications.
