York S1-9951-1541 Orifice
The York S1-9951-1541 is a precision-machined natural gas burner orifice designed for specific compatibility with York, Coleman, and Luxaire gas-fired systems. This #23 drill size component features a .154-inch bore, which is critical for regulating the gas flow required to achieve specified BTU outputs per burner. As a veteran technician knows, maintaining the correct gas manifold pressure—typically 3.5" W.C. for natural gas—relies entirely on the accuracy of the orifice sizing to prevent over-firing or incomplete combustion. This OEM burner spud is manufactured from high-grade brass to resist thermal degradation and corrosion within the burner box environment. When performing a furnace component replacement or a manifold rebuild, using the S1-9951-1541 ensures the flame pattern remains stable and the heat exchanger operates within designed temperature rises. This part is a direct-fit solution that eliminates the guesswork associated with generic aftermarket orifices that may not meet tight tolerances.
- OEX Accuracy: Specifically engineered for York equipment to ensure precise natural gas delivery.
- Superior Metallurgy: High-quality brass construction prevents thread galling and resists heat-related warping.
- Optimized Combustion: The #23 drill size ensures the correct air-to-fuel ratio for peak efficiency.
- Standardized Fit: Standard thread pitch allows for rapid field replacement during seasonal maintenance.
Common Questions
What happens if the wrong orifice size is used in a York furnace?
Using an orifice that does not match the S1-9951-1541 specifications can lead to serious issues. A larger orifice will over-fire the unit, potentially cracking the heat exchanger, while a smaller orifice will lead to under-firing, causing condensation in the flue and poor heating performance.
Is the S1-9951-1541 compatible with Propane (LP) systems?
No, this part is sized specifically for natural gas. LP applications require much smaller orifices due to the higher BTU content and higher manifold pressure of liquid propane. Do not use this for an LP conversion.
How do I verify if this #23 orifice is correct for my specific model?
You must reference the rating plate on the interior of the furnace cabinet. It will list the required orifice size based on the manifold pressure and the altitude of the installation. For most standard natural gas York units, the S1-9951-1541 meets the factory spud requirement.
