Gas Burner Set Up
a. Open the manual gas cocks on
the pilot and main lines of the gas
head.
b. Switch on the main power to the
burner. The water level relay is
equipped with a manual reset.
Depress the button on the box.
c. The flame programmer is the
main control in the panel box. The
programmer in conjunction with a
UV scanner “supervises” the ignition
sequence - proves the flame is satis-
factory, and finally “monitors” the
established flame. Should any fault
occur, either during the ignition
sequence or during normal running,
the programmer will immediately go
to “lock-out” and the burner will shut
down.
d. When the pilot flame is estab-
lished, the ultra-violet scanner sens-
es the flame. This signal is transmit-
ted back to the flame programmer
which opens the main gas valve giv-
ing a main flame.
e. If the installation is new or the
burner has been disassembled, the
burner may not fire at the first
attempt due to air which must be
purged from the gas lines. This will
result in the burner flame program-
mer going to lockout. Repeat the
procedure for starting the burner.
f. The main gas valve will remain
open as long as there is a demand
for heat and the flame is carrying a
sufficient signal to the flame pro-
grammer.
g. If the flame is not established at
the start, the safety switch in the
flame programmer control will open
the contacts and shut off the burner.
h. Push the reset button on the con-
trol to reset. If trouble persists, it
may be necessary to check the UV
scanner. See Maintenance Section
for procedure to check UV Scanner.
Air adjustment for Fulton LE Gas
Fired Steam Boilers.
a. The primary air adjustment or
main air control is located at the fan
housing inlet. This control is used to
supply the burner with air needed to
facilitate good combustion. Too
much or too little air will result in
poor combustion. Using a CO
2
or O
2
tester, it is possible to determine the
percent of excess air in the combus-
tion mixture. Refer to Factory Test
Fire Report for acceptable ranges.
