oil furnace question

I have an american standard arcoliner furnace that is oil fired,seam heat. Does anyone know what the pressure regulator should be set at? It currently is set at 2.5 lbs.for cut in and at 1 lb on the differential.The system is rated for 15 lbs steam but the pressure only goes to about 3 llbs when the unit is running.Any way to get more pressure out of this unit? Thanks,Steve

More pressure = less heat. You would be better off to reduce the setting to not exceed 2 psi. It is very unusual to need more than 2 psi to heat a house. Excessive pressure (3+ psi) will hold the radiator vents closed and do other nasty things. You may have other problems.
