York S1-029-20423-044 Orifice

The York S1-029-20423-044 #44 Burner Orifice is a precision-engineered component designed for exact gas flow regulation in residential gas furnaces. Featuring a .086 drill diameter, this orifice is critical for technicians performing manifold pressure adjustments or burner manifold maintenance on York, Luxaire, and Coleman heating systems. Using an OEM S1-029-20423-044 replacement ensures that the BTU input remains consistent across the burner assembly, preventing issues such as under-firing or over-firing which can lead to heat exchanger stress or soot accumulation. This furnace burner orifice is machined from high-quality brass to provide thermal stability and internal corrosion resistance, maintaining the integrity of the gas-to-air mixture over long-term operation. For contractors, installing the correct #44 burner orifice is essential for achieving a clean flame pattern and ensuring the combustion process meets manufacturer specifications. This part is a standard requirement when addressing HVAC burner nozzles that have become clogged or damaged during service.

• Precision Flow Control: The .086 burner orifice size ensures accurate fuel delivery for optimized combustion.
• OEM Compatibility: Specifically designed for seamless fitment in York, Luxaire, and Coleman furnace manifolds.
• Durable Construction: Machined brass design resists fouling and withstands the high-temperature environment of the burner box.
• Efficiency Restoration: Replaces worn or incorrect orifices to restore factory-spec furnace performance and efficiency.

What is the drill size for the York S1-029-20423-044?
This component is a #44 orifice, which corresponds to a .086 drill diameter.

Is this orifice compatible with propane (LP) conversions?
The S1-029-20423-044 is typically sized for natural gas applications. For LP conversions, refer to the specific unit’s conversion kit instructions and altitude adjustment charts to verify the required drill size.

How do I identify a clogged burner orifice?
A clogged orifice often results in a weak, yellow flame or a failure to cross-light across the burner assembly. Inspect the burner burner orifice for debris or oxidation that may be restricting gas flow.
