Fulton Electric (FB-L) Steam Boiler - Manual (Page 29)

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 glass
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.
6. Clean water pump strainers.
7. Check operation of all steam traps on
condensate return system.
8. Remove pipe cap at the cross connection
below water column and clean nipple
into boiler. Boiler must be cold and
water level below pipe, (30 - 100 BHP
only).
Recommended Quarterly
Maintenance
1. Shut off the boiler completely and drain.
2. Remove the handholes 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
this inspection will be dependent on the
condition of the water side of the boiler.
3. Replace handhole gaskets using the
following procedure.
a) Remove old gasket and thoroughly
clean the surface on the boiler and
the plate.
b) Place gasket on handhole plate. Be
sure the gasket is pushed down tight
on the plate. Do not use any grease,
lubricant or adhesive.
c) After the plate is in the boiler and the
gasket is in place, set yoke and
tighten nut only enough to provide a
snug fit. Make it hand tight and then
snug with wrench about 1/4 turn. Do
not compress excessively.
d) If the gasket leaks while pressure is
being built up, tighten only enough to
stop leakage. Never tighten more
than necessary to prevent leakage.
Excessive tightening may shorten life
of the gasket.
4. Refill the boiler with fresh water.
Recommended Six
Month Maintenance
1. Steam Safety Valve - Under normal
operating conditions a “try lever” test
should be performed approximately
every six months. Testing should be
performed more often under severe
service conditions or if corrosion or
deposits are noticed within the valve
body. A “try lever” test should also be
performed at the end of any extended
non-service period. Check that the
steam safety valve is operating properly
by conducting a “try lever” test.
CAUTION
Prior to performing the “try lever” test,
be certain to take precautions as a loud
noise and high velocity steam will
discharge freely from discharge port
and through drain hole provided in the
side of the valve body.
a) The test lever is designed to be
activated only when 75% or more of the
relief pressure is reached, otherwise
distortion could result. The valve
should be tested at or near maximum
operating pressure by holding the test
lever fully open for approximately 5
seconds to flush the valve seat free of
any debris or sediment.
b) Permit the valve check to snap shut.
c) If lift lever does not activate and there is
no evidence of valve discharge, shut
down equipment immediately and
replace valve.
