Nordyne 660149R LP Pilot Orifice

The Nordyne 660149R LP Pilot Orifice is a metering insert used in a gas burner system to control the flow of liquefied petroleum (LP) gas to the pilot assembly in HVAC systems. It is installed in compatible furnaces and heating equipment, where it fits into the pilot tubing or valve outlet and establishes a precise gas passage size for stable ignition performance. The orifice works within the pilot circuit alongside the gas valve and burner, ensuring a controlled fuel stream that supports consistent flame establishment during system startup. It is commonly used in residential and light commercial heating units during fuel configuration setup, or replacement of control components in compatible LP gas systems.
