Description
The Fireye 53-121 Orifice Kit provides precision flow restriction components for combustion control systems in HVAC systems, delivering calibrated openings that regulate fuel or air delivery rates to burners for optimal flame features and efficient operation. The kit installs in fuel supply lines or pilot assemblies, creating controlled pressure drops that establish predictable flow volumes matching burner design requirements. Precision-drilled apertures maintain consistent delivery across varying supply pressures, supporting stable combustion and preventing flame instability caused by excessive or insufficient fuel flow. Resistant elements prevent erosion from high-velocity gas streams and corrosion from combustion byproducts.
