Most gas range model#'s will have at least 1 G in it.
I found the manual and it said that you can adjust how low the flame gets by pulling off the knob and turning the screw inside the stem. adjusting each burner individually
Many ( not all ) can be adjusted like that...

Have any older wire coat hangers around?....file down one end like a flat screwdriver and use to adjust.
