Sorry friend. Despite what you may have been told or think, it takes more than orifice change to convert a vent-free gas heater from one gas type to another. In any event, you "might" get it to work, but it would override the built-in safety features that are designed to shut it down within one minute, if something goes wrong. If you still have your Owners Manual, you will see that it can not be safely converted.
I highly recommend that you don't even attempt it. Is trying to saving a few $$ worth risking your or your family's life?
