Why Choose the Rheem-Ruud FP-21?
When a job site requires LP fuel instead of natural gas, using the correct OEM conversion kit is critical for safety and equipment warranty compliance.

This eliminates guesswork and reduces the risk of improper combustion, gas leaks, or equipment damage that can result from using non-OEM parts.
Applications
