Pressure?

in THE MAIN WALL
I have two single radiator line propane fired steam boilers. One 20+ years old and the other a 16 year old Peerless 61 series. What is the purpose of the cut-in settings and the cut-out settings (cut-in + number on knob). What would be the optimum settings?
Thanks

    pressure

    the cut-in pressure is the pressure at which the boilers burner will start. you add the diffrential to this an that is the point at which the boiler will shut off.if you have subtractive style you set the cut-out at the pressure you want the burner to shut off at.you subtract your diff. pressure from that and that will give you your cut-in pressure.set the cut-i at .5 psi then set your diff. at 1 this will do the trick.
    get a copy of dans book THE LOST OF STEAM he explains all of this beautifully.
