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
tankless water heater has been set up to operate with propane. Check the rating plate on the tankless water
heater to see which fuel source the particular appliance 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 appliance after the
conversion is completed.

Disconnect power supply before any wiring/service is performed. Failure to do so could
result in damage to appliance and/or electric shock.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
