Description
The York S1-1NP0820 is a factory-engineered conversion kit designed to convert compatible York furnaces from natural gas (NG) operation to liquid propane (LP) fuel. This kit includes stainless steel burners, delivering superior corrosion resistance and long-term durability compared to standard aluminized steel alternatives — an ideal choice for installations in humid or coastal environments where burner longevity is a priority.
Using a genuine OEM York conversion kit ensures proper fuel metering, combustion performance, and safety compliance. Attempting a fuel conversion with non-OEM components can compromise system efficiency, void manufacturer warranties, and create safety hazards. The S1-1NP0820 is engineered specifically for York equipment, providing a precise fit and reliable operation from day one.

Why Choose Stainless Steel Burners?
Stainless steel burners resist oxidation and corrosion far better than standard burner materials, extending service life and reducing maintenance intervals. This makes the S1-1NP0820 an excellent long-term investment, particularly in applications where moisture, humidity, or aggressive environmental conditions are present.
