SFC 99 / SFB 99  - Fuel Conversion to 
Propane - P-804

 

Note

If converting from propane to natural gas, order the natural gas conversion parts kit (IBC Part # P-
805) from your authorized IBC distributor.

Use the propane gas conversion parts kit if the fuel source at the site uses propane and the appliance has 
been set up (factory fire-tested) to operate with natural gas. Check the rating plate on the appliance 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.

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.

The appliance will automatically de-rate the maximum input at a rate of approximately 2% per 1,000' above 
4,500'. The gas valve's zero-governor ensures that the gas-air mixture is not affected at altitude.
