Recommended Daily
Maintenance Schedule
a ) The following procedures should be
carried out daily. They are designed to
prevent the build up of scale, silt, or
sludge in the bottom of the boiler and
in the pipes leading to the water
gauge. In addition to these proce-
dures, the advice of a water treatment
supplier should be sought and fol-
lowed. An ASME Section VIII blow off
receptacle must be provided for the
appropriate pressure.
b ) Blow down the boiler each
morning by starting the boiler and
generating not more than 10 PSI
(.703 kg/cm 2 ) of steam. Turn on tap
water to blow-off separator, then
open the boiler blow off valve for
approximately 10 seconds, then
close the valve. Shut off tap water
to blow-off separator.
Blow Down Boiler Daily. Shown is the
blow down "Y" valve.
NOTE
If the boiler is being operated auto-
matically on a time clock, the blow
off operation may be done once
during the working day and once at
the end of the day when at 10 PSIG
or less.
c
) Blow down water column each
morning when boiler is at 10 PSI (.703
kg/cm 2 ) by opening the water column
and the water gauge blow off valves
for approximately 5 seconds, then
close the valves.
Blow down water column each morning
by opening the water column and the
water gauge blow-off valves.
d) If the feed water is being treated by
compounds, make sure that this treat-
ment is carried out carefully and
according to the manufacturer's
instructions.
NOTE
Fulton recommends that the feed-
water treatment should be added
between the pump and the boiler.
e)
When first starting the boiler each
day, make sure ignition and burner are
working properly.
f) Check water level in sight glass.
g) Check to be sure feed water pump
is working.
h) For float type water level control,
blow-down float chamber.
Recommended Weekly
Maintenance Schedule
a) Check 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 the burner operating, open the
boiler blow off valve. 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 low water
electrode in the water column assem-
bly and/or the boiler shell. Manual
reset of the low water relay is required.

Maintenance Schedule
WARNING
Make sure main power switch is off
before starting work.
a)
Clean the water gauge glass.
CAUTION
Do not clean the gauge or gauge
glass while pressurized or in opera-
tion.
1)
Clean the water gauge glass using
a commercial non-abrasive glass
cleaner. Use diluted acids such as
hydrochloric (muriatic) acid when regu-
lar cleaners do not seem to work. Do
not use wire brushes or any other
abrasive materials which could scratch
the glass. If any leakage is evident,
replace the gaskets.
Clean Glass; Replace Gaskets If
Leaking
2) Always replace the high impact
plastic gauge glass protector which is
standard on all Fulton Boilers.
b) Clean water pump strainers.
c) Check scanner or flame rod and
ignition electrodes.
d) Check starter contacts. Burned or
pitted contacts should be replaced.
Do not use sand paper or file to clean.
e) Clean water traps and strainers in
fuel lines.
f) Check operation of all steam traps
on condensate return system.
