Rinnai rl75i Gas Conversion Kit Natural to Propane

Product Description

The RINNAI rl75i Gas Conversion Kit is a genuine OEM replacement part engineered to convert compatible Rinnai water heater units from natural gas to propane fuel operation. Designed to match original factory specifications, this kit delivers a precise, reliable fit that maintains safe and efficient combustion performance after conversion. The kit ships in a package measuring 15.5 inches long, 15.4 inches wide, and 4 inches tall, and weighs 5 pounds. Licensed plumbing or HVAC technicians handling gas appliance fuel conversions will find all necessary OEM components included for a complete, code-compliant transition from natural gas to LP service.

This conversion kit is intended for use with Rinnai RL75i and V75i series tankless water heater units. It is suited to residential and light commercial applications where a fuel source change is required — for example, when a property transitions from utility natural gas service to on-site propane supply.

Installation Notes

Gas conversion work must be performed by a licensed plumber or gas fitter in accordance with local codes and the appliance manufacturer's service instructions. Shut off the gas supply and disconnect power to the unit before beginning any conversion procedure. Do not attempt fuel-type conversion without the correct OEM kit for the specific model; use of non-matching parts can create unsafe operating conditions. After installation, verify for gas leaks at all connections using an approved leak-detection method before returning the unit to service.
