York S1-029-21182-245 Burner Orifice

Maintain precise combustion and high-efficiency performance with the York S1-029-21182-245 Burner Orifice. As a veteran-grade OEM furnace replacement part, this #45 drill size orifice is engineered to the exact tolerances required for controlled gas metering in residential heating systems. It serves as the direct replacement for the legacy 029-21182-045 part number, delivering the specific gas-to-air mixture necessary to prevent incomplete combustion or thermal stress on the heat exchanger. For contractors performing a furnace burner repair, sourcing authentic York HVAC parts ensures the manifold pressure remains consistent across the burner assembly, preserving the factory-specified BTU output.

Constructed from high-grade, heat-resistant brass, this orifice is compatible with various York gas furnace models, including the CP9C, LP9C, and TM9 series. When troubleshooting York furnace burners that won't stay lit or display poor flame characteristics, replacing a clogged or corroded orifice with a fresh York S1-02921182245 is standard protocol to restore reliable ignition. Its precision-drilled #45 aperture is essential for maintaining the narrow operating window of modern high-efficiency equipment.

• OEM Precision: Genuine #45 burner orifice ensures factory-accurate gas flow regulation.
• Direct Supercession: Seamlessly replaces 029-21182-045 with no field modifications required.
• Enhanced Combustion: Corrects improper flame patterns and supports optimal energy efficiency.
• Durable Brass Build: Resists high-temperature oxidation and chemical corrosion within the burner box.
• Wide Compatibility: Tailored for York, Coleman, and Luxaire gas-fired heating units.

What are the symptoms of a faulty burner orifice?
Technicians typically look for yellow tipping, uneven burner flames, or delayed ignition. In severe cases, a clogged orifice can cause a pressure imbalance, leading to frequent short-cycling or safety lockouts.

Can I use a tool to clean a blocked #45 orifice?
While some use wire brushes, veteran technicians recommend a full replacement. Precision-drilled openings can be easily damaged or enlarged during cleaning, which alters the gas flow rate and can lead to dangerous over-firing of the furnace.

Is this part suitable for LP to Natural Gas conversions?
This specific #45 orifice is matched to specific fuel types and altitudes. Always verify your manifold pressure and local gas specifications against the equipment rating plate to ensure a #45 drill size is the correct selection for your application.
