What do you mean, "flip the regulator cap", when converting from LP to NG?
ANSWER Hello Kevin,
There is a brass nut on top of the regulator. When you remove this nut, there is a small piece, usually white plastic, that will snap off. Before snapping it off, note which way it is installed. You will now flip this part and reattach it to the bottom of the brass nut in the opposite direction from the original direction. This changes the orifice size in the regulator.
