Pressuretrol Settings

I have a Burnham MegaSteam boiler Model MST396 ST-HB with a Honeywell pressuretrol Model L404F1367. This is the subtractive type. The house is fitted with Hoffman 1A Adjustable steam vents. I would like to know how I should set the pressuretrol. Thanks for the reply.

Set the main (right hand) scale to 2 psi and the differential setting to 1.5 psi. This should yield a shut off of 2 psi and a turn on of 1/2 psi. The maximum steam pressure should never exceed 3 psi on a 1 pipe steam system. Just to be sure; how many pipes are connected to any of the radiators? The answer should be 1.
