    All the way to the bottom (.5 psi).

    But don't try to force it past the bottom. Just turn the top screw just until the indicator gets just to the bottom of its slot there.

    Then you can loosen that bottom screw and carefully remove the cover and ensure the white dial in there is displaying the "1" toward you (1 is the correct setting for that white dial).,

    Make sure you test the operation of the P trol after adjustment. If the cut in is to low the boiler may not restart and you may have to tweak the setting up slightly. If you haven't cleaned the pigtail that is also something that should be done every couple of years.
