G E Conversion; nat. gas to propane

Need to convert from natural gas to propane, GE says no kit is needed, just reverse orffices. How many are there and where are they located and any hints? Thanks

The conversion instructions and LP orifices can be found attached to the range next to the pressure regulator.
