Rand and Reardon 106939-01 is a gas conversion kit that can be used to convert an RRG gas boiler from natural gas to LP/propane or vice versa. This can be useful if you are moving to a new home with a different type of gas supply, or if you want to change the type of gas you are using for financial or environmental reasons. The kit includes a new gas valve, pilot assembly, main burner orifices, pilot tubing, and a converted boiler rating label.

Installing the conversion kit requires some technical expertise, so it is recommended to have a qualified service agency perform the installation. The instructions included with the kit provide detailed steps on how to remove the existing gas valve, main burner orifices, and pilot assembly, and how to install the new components. It is important to follow the instructions carefully to ensure that the conversion is done correctly and safely.
