blown through and checked for correct reading. When the steam
pressure is about 300 kPa (3 bar) below the normal operating value the
safety valves should be lifted and released using the easing gear.

bypasses should then be closed. The water level in the boiler should be
carefully checked and the automatic water regulating arrangements
observed for correct operation.
