11. Operating and Modulating Controls
The operating controls will not be used during the
burner setup, except that the high limit and operating
controls can cycle the burner off and should be set for
the highest allowable pressure for the application.
The high limit control should be set at the maximum
temperature or pressure allowed for the boiler vessel
or piping. The operating control should be set at a high
enough pressure to prevent this control from turning
the burner off unless the operating temperature or
pressure is at the maximum value. The modulating
control should be set at a value below the operating
control to prevent the unit from modulating immediately
after starting.
