FULTON VMP40 Installation, Operation And Maintenance Manual page 47

3. If the feed water is being treated by
compounds, make sure that this
treatment is carried out carefully and
according to the manufacturer's
instructions.
NOTE
Fulton recommends that the feedwater
treatment should be added between the
pump and the boiler.
4. When first starting the boiler each day,
make sure ignition and burner are
working properly.
5. Check water level in sight glass.
6. Check to be sure feed water pump is
working.
7. For float type water level control, blow
down float chamber.
Recommended Weekly
Maintenance Schedule
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-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 low water
electrode in the water column assembly
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.
1. Cleaning the water gauge glass:
CAUTION
Do not clean the gauge or gauge glass
while pressurized or in operation.
a. Clean the water gauge glass using a
commercial non-abrasive
cleaner. Use diluted acids such as
hydrochloric (muriatic) acid when
regular 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.
b. Always replace the high impact
plastic gauge glass protector which is
standard on all Fulton Boilers.
2. Clean water pump strainers.
3. Check scanner or flame rod and ignition
electrodes.
4. Check starter contacts. Burned or pitted
contacts should be replaced. Do not use
sand paper or file to clean.
5. Clean water traps and strainers in fuel
lines.
6. Check operation of all steam traps on
condensate return system.
7. Remove brass pipe plug at the cross
connection below water column and
clean nipple into boiler. Boiler must be
cold and water level below pipe.
Recommended Semi-
Annual Maintenance
Schedule
1. Cleaning the gas burner assembly:
a. Disconnect the gas head from the
burner by disconnecting the union.
Remove the burner plate screws.
Withdraw the burner assembly and
clean the flame rod and ignition
electrode.
b. Check that the settings of the flame
rod, if applicable, and ignition
electrode correspond to those in the
illustration below.
c. Reassemble the burner assembly
and check the flame rod setting or
scanner setting.
glass
d. Check the combustion efficiency of
the burner and adjust if necessary.
e. Clean probe on top of boiler shell and
probes in water column. There must
be no pressure on the boiler during
the removal of the probes.
f. Check refractories for soot or
breakage and inspect the stainless
steel ring (50-100 HP only).
g. With the boiler under no more than 15
PSI pressure, check that the steam
safety valve is operating by lifting the
lever.
2. Drain condensate tank and clean tank
by flushing with hose. Check float valve
operation.
3. Check electrical controls and motors for
correct operation.
4. Check water pump for correct operation.
5. Shut off the boiler completely and drain.
6. Remove the hand holes and inspect the
interior of the vessel for scale or sludge
deposits. The amount of deposits will
indicate the efficiency of the water
treatment being used. The frequency of
the inspection will depend on the
condition of the water side of the boiler.
7. Replace hand hole gaskets using the
following procedure:
a. Remove the hand hole assembly
