### 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).
