Section 2 START-UP AND OPERATION STEAM BOILERS

The steam pressure in the boiler is regulated by the Boiler Operator. This is a pressure control which senses the steam pressure and turns the boiler on and off accordingly. This control must be operationally tested. Adjust the pressure setting on the control to a pressure less than the boiler pressure (as shown on the boiler pressure gauge).

Water-tube boiler - Wikipedia

High Pressure Water Tube Boiler: The heated water then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam will reenter the furnace through a superheater to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure.

Proper Pressure Settings for Residential Steam Boiler

You want as little pressure in the system as is possible so the fact you don't see the gauge move, but you get steam to all of the radiators is a GREAT thing. The boiler must be properly sized and working well. The Pressuretrol should actually be a safety devise and should not have to control the pressure in a system that is properly sized.
