York S1-1PS3307 Conversion Kit
The York S1-1PS3307 High Altitude Conversion Kit is a critical component for ensuring proper combustion and operational safety in high-elevation installations above 5,000 feet. Specifically engineered for York residential furnaces, including the TM9X single-stage series and select 95% AFUE models, this kit includes a high-altitude pressure switch factory-calibrated to 0.80 IWG. At elevated altitudes, lower oxygen density can lead to suboptimal air-to-fuel mixtures, causing sooting or incomplete combustion. This OEM pressure switch prevents these issues by accurately monitoring the draft inducer performance under reduced atmospheric pressure.
For technicians servicing HVAC systems in mountain regions, the S1-1PS3307 provides a precise field-conversion solution to maintain furnace efficiency and equipment reliability. It is compatible with specific 40 MBH and 80 MBH 95% furnaces but is not intended for use with Ultra LoNOx models. By replacing the standard factory switch with this high-altitude variant, you ensure the inducer motor maintains the correct safety threshold, protecting the heat exchanger from premature failure and maintaining combustion stability throughout the heating cycle.
Key Benefits:
- Precise Pressure Calibration: Features a dedicated 0.80 IWG pressure switch for accurate signal detection at high elevations.
- Combustion Protection: Prevents carbon monoxide production and sooting caused by improper air-to-fuel ratios.
- OEM Compatibility: Designed strictly for York, Luxaire, and Coleman TG9S and TM9X furnace series to ensure seamless integration.
- Safety Compliance: Meets manufacturer requirements for safe operation in altitudes exceeding 5,000 feet.
Common Questions:
Can I just adjust the factory pressure switch for high altitudes?
No, adjusting the original pressure switch is unsafe. You must install the S1-1PS3307 kit to ensure the burner shuts down correctly if venting or combustion air becomes restricted at high altitudes.
Is this kit required for all installations above 2,000 feet?
Standard York units are usually rated up to 5,000 feet without a switch change, though local codes may require manual derating. This specific kit is mandatory for the specified models at 5,000+ feet.
Does this kit include gas orifices?
This kit primarily focuses on the pressure switch conversion. Depending on the specific altitude and fuel type (Natural Gas or LP), separate manifold derating or orifice changes may be required per the National Fuel Gas Code.
