I have an Onan 2500 LP generator. What is the red knob on the LP regulator for? It has adjustment numbers from 0 to 6 molded into the knob.

That knob should be to bring pressure up and down with 0 being off or the lowest range of the regulator. This regulator is adjustable for different applications apparently.
