I'm toying with the idea of running a buried natural gas line out to
the garage for a hot air furnace as well as my foundry furnace (now
propane)

Now that everybody has given you the answers to code problems and other
such stuff, there's one problem with using the natural gas with your
foundry furnace. After the gas goes through the meter it comes out at
about, IIRC, at 7psi or something like that. Not enough pressure and
volume to run a foundry furnace.
