York S1-9951-0821 Orifice
The York S1-9951-0821 Orifice is a precision-engineered #45 (.082) LP gas orifice designed for liquid propane conversions and manifold pressure adjustments in residential and light commercial heating equipment. As a genuine HVAC OEM replacement part, this component ensures the precise fuel-to-air ratio required for clean combustion and optimal BTU input. This York burner orifice is critical for technicians performing LP gas conversion for York furnaces, mitigating issues like soot accumulation or incomplete combustion caused by incorrect aperture sizing. Built to exact factory tolerances, the S1-9951-0821 maintains the integrity of the heat exchanger by preventing over-firing. Whether you are conducting routine maintenance or a full system conversion, using this propane gas orifice replacement ensures the manifold pressure remains within manufacturer specifications for stable flame characteristics across the burner assembly. This part is compatible with select York, Luxaire, and Coleman units requiring a #45 drill size.
Key Benefits for HVAC Professionals
- Precision Metering: The #45 (.082) orifice size provides exact gas flow regulation for liquid propane applications.
- OEM Compatibility: Guaranteed fit for York HVAC gas manifolds, eliminating the need for field modifications.
- Combustion Efficiency: Maintains proper manifold pressure to support the designated AFUE rating of the furnace.
- Direct Replacement: Simplifies service calls by matching the exact physical and flow specifications of the original factory component.
Common Technical Questions
Is this orifice suitable for Natural Gas to Propane conversions?
Yes, the S1-9951-0821 is specifically sized at #45 (.082) for LP (Liquid Propane) applications. Technicians should verify the required BTU input and manifold pressure against the unit rating plate when converting from natural gas.
Which HVAC brands are compatible with this part?
While branded as a York component, this orifice is a standard Johnson Controls (JCI) part used across York, Coleman, and Luxaire furnace models that utilize the S1-9951 series orifice configurations.
Why is the #45 drill size significant?
The .082-inch diameter is the calibrated opening required to deliver the correct volume of propane, which has a higher energy density than natural gas, ensuring the burner does not overheat the heat exchanger.
