Recommended Weekly Maintenance
Schedule
Weekly maintenance and inspection must include
checking that the low water cut-off relay is operating
correctly in the following manner:
1. Make sure that the boiler is cool with little or no
pressure showing on the steam pressure gauge.
2. With burner operating, open the boiler blow-
down valves. When the water drops below the
required level (note the level in the water gauge
glass), the burner should shut off; this is when
the water level falls below the primary low water
cutoff device in the water column assembly and/
or the boiler shell. Manual reset of the secondary
low water cutoff device is required.
! CAUTION
Correct combustion air adjustment is essential for the
efficient operation of this boiler. If an adjustment to
the combustion is necessary, the flue gas composition
should be checked with a combustion analyzer to set
conditions.
