STARTING UP AND REGULATION
Check that there is fuel in the tank.
• Make sure that the combustion head is long enough to enter
the furnace following the measure specified by the boiler ma-
nufacturer.
• The nozzles fitted on the burner should match the boiler capaci-
ty but, if necessary, replace them with others. In no case should
the quantity of fuel delivered exceed the maximum amount re-
quired by the boiler and the maximum amount allowed for the
burner.
• Remember that the combustion head is designed for nozzles
with a 45° spray angle.
• Only in special cases can nozzles with a different spray angle
be used. In these cases, however, make sure that the nozzle
with a different spray angle will not cause problems, such as:
blowoff, disk or combustion head fouling, violent ignition, etc...
Make sure that there is not an electrical connection (jumper)
between the second stage thermostat terminals or that the ther-
mostat is not connected.
Make sure that the return pipe to the tank has no clogging, e.g.
closed gate valves, plugs, etc.
Close the main switch and the boiler thermostats in order to start
up the motor and the ignition transformer and, after approximately
10”, the solenoid valve. On inserting the latter expose the pho-
to-resistance to a light source so that the burner does not “lock-
out”.
When the piping is filled (when fuel comes out of the nozzle) stop
the burner and put the photo-resistance back in its place.
CAUTION / WARNING
Should it be necessary to purge air, this can be done by
loosening the special fitting which the pump is provided with
(see 8945/2). Do not illuminate the photo-resistance before
the solenoid valve has cut in because, in this case, the con-
trol box will go to “shut down”.
• Slightly open the air regulator to allow the flow of air deemed
necessary for burner operation in the first stage and lock it in
this position.
• With the burner running in the first stage, regulate the air accor-
ding to the amount required to ensure proper combustion.
• We recommend keeping the air quantity for the first stage at a
low level to ensure a perfect ignition even in the most difficult
conditions.
• Using the second stage air regulation cam for the models fit-
ted with servomotor, Set the air damper opening for the second
stage to the position deemed necessary for the required fuel
output.
Make sure that there is not an electrical connection (jumper)
between the second stage thermostat terminals or that the ther-
mostat is not connected.
• Now the equipment is activated again and moves to the second
stage automatically, according to the program set by the pro-
grammer.
The burner is equipped with a flame disc adjustment screw that
allows you to optimise combustion, reducing or increasing the air
passage between the disc and head.
When the fuel output is low, unscrew the adjustment screw to re-
duce the air passage between the disk and head. If the output is
higher, screw it to increase the air passage.
After changing the flame disk position, adjust the positions of the
air regulation damper and then check for proper ignition.
