yes!

That is not true. The actual burner has nothing to do with NG or LP. The only differences between an appliance fabricated to use LP or NG is the gas orifices and gas regulator are different and the valves and burner carburetor has to be adjusted. The burners are the same in both LP and NG models.

You have to change the size of the gas suypply orifice.

Yes, if you change the orfice out, the lp orfice is smaller than ng. Orfices sized by BTU's.

That's less than half the btu's required what do you think!
