Fulton Classic ICX or FB-F Vertical Tubeless Boilers (Steam) Oil Fired - Manual (Page 34)

Operation
Boiler Controls
a) Flame Safeguard/Burner
Control – this is the main control in
the panel box. The programmer in
conjunction with a sensing device,
either a cad cell (4-15 h.p.)or an
ultra violet scanner (20-60 h.p.),
"supervises" the iginition sequence -
proves the flame is satisfactory -
and finally "monitors" the estab-
lished flame. Should any fault
occur, either during the ignition
sequence or during normal run-
ning, the programmer will immedi-
ately go to "lock-out" and the burn-
er will shut down.
b) Low Water Cut-Off – probe
type--cuts off the unit when water
level is too low. As a standard fea-
ture, Fulton boilers are equipped
with CSD-1 controls which include a
manual reset feature on the burner
low water cut off relay and CSD-1
controls also feature a second low
water cut off relay.
CAUTION
Do not tamper with the safety
features of the low water safety
cut out.
c) Pressure Relief Valve – limits
maximum operating pressure of the
boiler.
d) Operating Steam Pressure
Control – located in the control
panel box and connected to the
steam pressure gauge assembly by
means of a copper tube. The pres-
sure control regulates the on/off
cycle of the burner, shutting the
burner off when maximum pressure
is reached and switching on when
the steam pressure falls below a
predetermined level.
e) Sight Glass Isolation Valves –
The brass sight glass isolation
valves are equipped with an internal
ball check. In the event that a sight
glass should break, the ball will
seat, preventing the discharge of
steam and water. The brass valve
stem must be opened fully to arm
this capability. If the valve is in any
other position than full open, the ball
will not seat. For added safety all
Fulton boilers are equpped with
gauge glass protectors.
f) High Limit Pressure Control –
located in the control panel box
and connected to the steam pres-
sure gauge assembly by means of
a copper tube. The pressure is
usually set 10 to 15 PSI (.703 -
1.054 kg/cm
2 ) above the operat-
ing pressure, but below the maxi-
mum pressure of the pressure
relief valve. If the pressure
exceeds the high limit pressure
control setting, the boiler will auto-
matically shut off. The high limit
pressure control must be manually
reset by depressing the plunger
located on top of the control.
WARNING
When stopping the boiler for any
extensive repairs, shut off main
disconnect switches on both the
boiler side as well as the feed
water side.
NOTE
To ensure that your Fulton Steam
Boiler is kept operating safely
and efficiently, follow the main-
tenance procedures set forth in
Section 4 of this manual.
