York S1-1PS3314 High Altitude Furnace Conversion Kit — Overview
The York S1-1PS3314 is a factory-engineered high altitude conversion kit designed specifically for York 33-inch furnaces. When a furnace is installed at elevated locations, reduced air density can negatively impact combustion efficiency, heat output, and safe operation. This conversion kit provides the necessary components to recalibrate and adapt the furnace for reliable, code-compliant performance at high altitude installations.
Key Features
- Designed for York 33-inch furnace models requiring high altitude adaptation
- Factory-engineered OEM conversion kit for precise fit and function
- Ensures proper combustion air-to-fuel ratios at elevated installations
- Supports safe, efficient furnace operation where standard sea-level settings are insufficient
- Helps meet local building codes and manufacturer specifications for high altitude use
- Direct OEM replacement — no modification or fabrication required
Why High Altitude Conversion Matters
At higher elevations, thinner air reduces the oxygen available for combustion. Without proper adjustment, furnaces can run rich, produce excess carbon monoxide, and suffer reduced efficiency or nuisance lockouts. The York S1-1PS3314 conversion kit addresses these challenges with components calibrated for high altitude conditions, restoring safe and efficient furnace operation.
Application
- Compatible with York 33-inch furnace configurations
- Intended for installations at high altitude locations (typically above 2,000 ft elevation)
- Suitable for residential and light commercial York furnace applications
