York S1-029-20422-056 Orifice

Ensure reliable ignition in gas-fired heating systems with the York S1-029-20422-056 Pilot Orifice. Specifically engineered for use in York-branded HVAC units and gas control applications, this #56 Pilot Orifice features a precise .0465-inch diameter to regulate the fuel-to-air ratio required for consistent pilot flame stability. As an authentic OEM replacement part, the S1-029-20422-056 is critical for maintaining the proper gas flow to the pilot burner, preventing common field issues such as delayed ignition, soot buildup, or nuisance lockouts caused by inadequate pilot flame sensing.

In the field, a clogged or corroded heating system pilot orifice is a primary contributor to intermittent burner operation. This precision-drilled component is designed to withstand the thermal stresses found in York pilot burner assemblies, providing the durability needed for high-demand residential and commercial rooftop units (RTUs). When performing seasonal maintenance or a call for "no heat," checking the S1-029-20422-056 orifice for debris or obstruction is standard protocol to ensure efficient combustion and system safety.

• Precise .0465" Diameter: Factory-calibrated (#56) for accuracy, ensuring the exact gas volume necessary for reliable pilot ignition.
• Direct OEM Compatibility: Designed by York for seamless integration with original gas control and heating systems, eliminating guesswork during installation.
• Enhanced Flame Stability: Correct sizing helps prevent misfires and flame lift-off, which are common symptoms of an incorrectly sized or worn orifice.
• Durable Construction: Manufactured using high-quality materials to resist standard wear and corrosion in demanding HVAC environments.

• What does a #56 orifice size mean for my furnace? The #56 designation corresponds to a .0465-inch hole size, specifically metered to provide the Btu/hr input required to sustain a stable pilot flame in compatible York systems.
• Can I clean the orifice if the pilot won't light? While debris can be removed, using a drill bit or wire can resize the hole and cause unsafe burner conditions. Technicians recommend replacing with a genuine S1-029-20422-056 to maintain factory specifications.
• How do I confirm the York S1-029-20422-056 fits my unit? Check the rating plate of your furnace or rooftop unit. This part is a standard replacement for many mid-efficiency and older high-efficiency York gas furnaces.
