Operation
Gas Burner Set Up
NOTE: Refer to Section LE
for LOW EMISSIONS BURNERS
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 program-
mer in conjunction with a sensing
device, either a flame rod or a UV
scanner, "supervises" the ignition
sequence - proves the flame is satis-
factory, and finally"monitors" the estab-
lished flame. Should any fault occur,
either during the ignition sequence or
during normal running, the program-
mer will immediately go to "lock-out"
and the burner will shut down.
d) When the pilot flame is estab-
lished, the flame rod (or ultra-violet
scanner) senses the voltage which
is created in the flame between the
flame rod and the gas nozzle
(ground). This signal is transmitted
back to the flame programmer
which opens the main gas valve
giving a main flame.
e) Fulton 4 - 30 h.p. natural gas fired
boilers can be equipped with flame
rods or UV scanners.
f) All Fulton propane or butane boil-
ers and 50 and 60 HP Fulton natural
gas boilers are standardly furnished
with UV Scanners.
1) 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 programmer going to
lockout. Repeat the procedure for
starting the burner.
2) The main gas valve will remain
open as long as there is a demand for
heat and the flame is carrying a suffi-
cient signal to the flame programmer.
3) 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.
4) Push the reset button on the
control to reset. If trouble persists,
it may be necessary to check the
flame rod setting or the UV scanner.
See Maintenance Section 4 for pro-
cedure to check flame rod setting or
UV Scanner.
