Recommended Daily Maintenance
Schedule
! WARNING
Check daily that the boiler area is free and clear of any
combustible materials , including ammable vapors
and liquids.
! CAUTION
Observe operating temperature and general conditions.
Make sure that the ow of combustion and ventilating
air to the boiler is not obstructed.
The following procedures should be carried out daily
as recommended maintenance. They are designed to
prevent the buildup of scale, silt, or sludge in the bottom
of the boiler and in the pipes leading to the water gauge.
In addition to these procedures, the advice of a water
treatment supplier should be sought and followed. An
ASME Section VIII blowdown tank must be provided.
1. Blow down the boiler each morning by starting the
boiler and generating not more than 10 PSI (.7 kg/
cm2) of steam. Turn on cooling water to blowdown
tank, if equipped, then open the boiler blow o
valve for approximately 10 seconds, then close
valve. See Figure 19. Be sure that the slow opening
valve (Y-Valve) is adjusted properly. The slow
opening valve is to be adjusted so that only 1-2”
of water empty from the boiler sight glass during
the 4-10 second bottom blowdown. During each
blowdown, there should be 1-2” of level drop in the
sight glass. If a manual method of cooling water is
used, be sure to shut o the cooling water supply.
If there are two bottom blowdown connections on
the boiler, both should be blown down daily.
2. Blow down water column each morning when
boiler is at 10 PSI (.7 kg/cm2) by opening the water
column and the water gauge blowo valves (see
Figure 20) for approximately ve seconds, then
close the valves. On boilers with oat type level
devices, refer to the water column cut sheet for
proper blowdown technique. Any water column on
the system should be blown down daily following
the above procedure.
3. If the feed water is being treated by chemical
