Note
If converting from natural gas to propane, order the propane conversion parts kit (IBC Part # P-802) from your
authorized IBC distributor.
Use the natural gas conversion parts kit if the fuel source at the site uses natural gas and the modulating water heater
has been set up to operate with propane. Check the rating plate on the water heater to see which fuel source the
particular unit has been set up with.
Using this conversion kit, a qualified technician will need to:
1. Perform a fuel conversion.
2. Perform a combustion test.
3. Fill in the information required on the fuel conversion labels, and affix them to the unit after the conversion is
completed.
Warning
This conversion kit shall be installed by a qualified service agency in
accordance with the manufacturer’s instructions and all applicable codes and
requirements of the authority having jurisdiction. If the information in these
instructions is not followed exactly, a fire, an explosion or production of carbon
monoxide may result causing property damage, personal injury or loss of life.
The qualified service agency is responsible for the proper installation of this kit.
The installation is not proper and complete until the operation of the converted
appliance is checked as specified in the manufacturer’s instructions supplied
with the kit.
