Description
The York S1-029-20423-037 is a genuine OEM #37 burner orifice designed as a direct replacement for compatible York furnaces and heating equipment. With a precisely drilled aperture of .104 inches (corresponding to a #37 drill size), this orifice meters gas flow to the burner with accuracy, ensuring consistent flame characteristics, proper combustion efficiency, and safe system operation.
Using the correct OEM orifice is critical to maintaining the manufacturer-specified fuel-to-air ratio. An improperly sized orifice can result in incomplete combustion, sooting, carbon monoxide production, or reduced heating efficiency. This York-specified replacement eliminates guesswork and keeps your system operating within designed parameters.
