Description
The Nordyne 661027 Natural Gas Main Burner Orifice 27 Drill is a fuel-regulating component that controls the supply of fuel gas to the burner assembly through the HVAC systems. It operates by guiding the gas through a 27-drill-bit-sized hole, which regulates the amount entering the burner tube to combine with the incoming combustion air and ignite. It is installed at the inlet of both primary burners on compatible furnace burner manifolds. It is part of the gas distribution channel, ensuring a stable fuel supply and a stable flame formation during heating.
