distributor.

Use the Natural Gas Conversion  kit if the fuel source at the site uses natural gas and the modulating boiler has been set 

up (factory fire-tested) to operate with propane. Check the rating plate on the boiler to see which fuel source the particular 

boiler 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 boiler after the conversion is 

completed.
