Rheem-Ruud FP-15-1PK Conversion Kit

The Rheem-Ruud FP-15-1PK Natural to LP Conversion Kit is a critical OEM component designed for field-converting gas furnaces and water heaters from natural gas to liquid propane. This technical package acts as the direct replacement for FP-15 and legacy part numbers including EP-70H and FP-11, ensuring exact fitment for 80% AFUE efficiency furnaces. As a veteran-grade OEM furnace conversion kit, it includes high-precision #54 orifices and multiple gas valve spring kits compatible with White-Rodgers, Honeywell, and Robertshaw controls. Utilizing an LP conversion kit for Rheem hardware ensures that manifold pressures are correctly regulated for stable combustion and optimal thermal output in areas where natural gas infrastructure is unavailable.

For contractors performing natural gas to propane conversion, this kit provides a ProTech authorized replacement that maintains system integrity without the risks associated with universal aftermarket sets. The inclusion of factory-coded burner orifices and specific spring regulators allows for a seamless transition, preventing soot buildup and ensuring the flame characteristics meet manufacturer specifications for select Ruud gas furnace parts and water heating units.

• Comprehensive Package: Shipments include required spring kits, detailed installation instructions, and mandated conversion labeling for code compliance.

Common Questions

Can I use the FP-15-1PK for 90% AFUE condensing furnaces?
No, this kit is specifically designed for 80+ efficiency (non-condensing) units. High-efficiency 90% systems typically require different orifice sizes and pressure settings; always verify your specific model number on the Rheem LP Conversion Index.

Is this kit compatible with all gas valve brands?
The FP-15-1PK includes spring conversion kits for the three most common gas valves used in Rheem and Ruud equipment: Honeywell, White-Rodgers, and Robertshaw. Verify the brand of the valve currently installed on your unit before starting the conversion.

Why is it necessary to use the included conversion labels?
Applying the conversion label is a safety and code requirement. It alerts future service technicians that the equipment has been modified for liquid propane, ensuring they do not attempt to tune the system back to natural gas pressures.
