Just to re-iterate what bobjohnson said, I did not have to do any reworking to get the Blichmann Floor Burner (linked above) to run on natural gas.
Initially, I ran it on propane using the included regulator. Later on, when I was able to invest in the natural gas quick disconnect and hose, I separately purchased the Natural Gas Conversion Kit, , which consists of a needle valve and a different orifice. Supply line connection to needle valve is 3/8" flare, so you may need an adapter (Lowes / HD plumbing section) to step down from 1/2" flare, or whatever your supply line fitting may be.
You can find the burner and the Natural Gas Conversion kit on most of the major homebrew supply websites - do some searching around if it is out of stock.
