I've converted a Big Easy oil less fryer and a patio heater from LP to
natural gas.  Not that hard.  Other than connecting to just gas line, all
you have to do is figure out what size to drill out the orifice.  You will
need a set of number drills.

Really?! I thought that was a DESA brand, and they went belly up a few
years ago. Pretty sure they made the gas (LP) logs in my place. Maybe
someone bought out the brand names -- oh well, not important.

There is usually some kinda brass orifice that meters the gas flow that
can be swapped out. LP runs like 2 or 3 PSI, and natural gas about 0.25
or 0.5, IIRC. (May be WAY off there, but the pressures are a bunch
different.) I'd google the part or model number and see if you can find
anyone selling parts for it. and are my
first go-to sites for parts. There's a good chance the manufacturer
originally sold conversion parts for it, and you can still buy them. May
even be some carry over or interchangeability between brands.

Don't know of any other way to reliably convert. Unless you had some
good specs and a way to precisely machine new orifice(s) for it (not
totally unthinkable for this crowd.)

Uuhhmm... yeah. Pretty readily and literally!
