Most LP appliances work on 10 to 11 in w.c. of manifold pressure. NG work at 3.5 to 5 in w.c.. 1 psi is 27.68 in w.c. to put things in perspective.
The LP orifice is indeed smaller.
LP gas has a BTU rating of 2500 BTU per cubic feet where NG is 1000 BTU per cubic feet. This is the test standard ratings for these 2 gases. Actually very slightly.
Some appliances are equipped with a flip flop gas valve as others have mentioned. A single screw in the center can be removed, flippd around and changing the gas pressure from one type to the other. This would only take care of the gas pressure, not the orifice.
I am a combustion engineer for a gas heater manufacture. We test run all heaters on LP gas. We only have to run the heaters for 20 seconds. If we kept a NG running on LP for any longer than this it will melt the blower wheel.
A 40,000 BTU burner set up for NG will burn at 60,000 BTU if connected to LP.
A 225,000 BTU burner set up for NG will burn at 331,000 BTU if connected to LP.
Please find someone who can work on gas appliances to check this one out for you.

I was suppressed when I looked up the part number of the auxiliary drive shaft because for some reason the part number went through a radical change and it lost its "Basic Part Number". Ford part numbers follow the following rules. Most part numbers are in three parts. The middle part is called the
