You want as low a pressure as possible. Look in the cover of your pressure switch. There should be a label that tells if the differential is additive or subtractive. The reading on the wheel is added or subtracted from the pressure setting. Some people will have two scales on the front, one being differential. Set your pressure to the minimum and your differential for 0.5psi and give that a try. The pressure will rise to the higher pressure and the burner will "cut-out" and then the pressure will drop to the lower and the burner will "cut-in"
