Control that the nozzle (60° spray angle) applied is
suitable for the boiler potentiality. The table shows the
delivery rates in kg/h of light oil with respect to the nozzle
size and the pump pressure (normally 12 bar). It should
be remembered that 1 kg of light oil is equivalent to
approximately 10.200 kcal). Make sure that the retum
pipe in the tank has no obstructions, e.g. gate valves,
closed plugs etc. Any eventual obstruction would cau-
se a breakage in the sealing surface situated on the
pump shaft. Close the main switch and the boiler
thermostats in order to start up the motor and the ignition
transformer and, after approximately 10 seconds, the
electric valve will cut in and expose the photoresistant
cell to a source of light until the burner stops (shut down).
When the pipelines have been filled up (and when fuel
has come out of the nozzle), stop the burner and put
the photoresistant cell back in its seat.
Note: Should it be necessary to purge air, this can be
done by loosening the special fitting which the
pump is provided with (see 0002900480,
0002900680).
photoresistant cell before the electric valve has
cut in because, in this case, the control box will
go to "shut down".
STARTING UP AND REGULATION
By acting on the regulating cam of 1st flame (see drawings n° 0002932270, 0002932092, 0002900621) set the 1st
flame air shutter to let in an amount of air deemed to be necessary for burner operation with 1st flame. Close isolating
switch and start the burner. With the burner running on 1st flame adjust, if necessary, the amount of combustion air by
acting on the regulating cam.
Stop the burner and then staff it again to be sure that ignition takes place correctly. Open isolating switch to stop the
burner and connect the terminals of the thermostat of 2nd flame. Now connect the burner again: it will staff with 1st
and 2nd flame. With the burner running on 2nd flame adjust, if necessary, the amount of combustion air means of the
regulating cam. The burner is provided with a regulating cam of combustion head. Make the regulation so as to obtain
Co
from 10 to 13% with smoke number not exceeding 2 of Bacharach scale.

USE OF THE BURNER
The burner operates fully automatically, therefore it is non necessary to carry out any kind at adjustment during its
operating. The "block" position is a safety position reached by the burner automatically when some of the components
of the burners or the plant do not work properly. It is necessary to check then whether the cause to the problem is a
dangerous one before unblocking the burner. The causes to the block may be temporary, for example when air in
inside the pipes. When it is unblocked, the burner starts operating properly.
If the burner stops three or four times at a stretch, it is necessary either to loock for the problem and solve it or ask for
the intervention of the after sales service. The burner can remain in the "block" position without any limit in time.
In emergency cases it is advisable to close the fuel valve, and disconnect the burner electrically.
MAINTENANCE
At the end of the heating season, it is usually advisable to clean the filter, blast tube (disc, insulators, electrodes,
nozzles), combustion air passages and photoconductive cell. To clean nozzle passages, use soft material
(e.g.wood,plastic). Replacement of nozzles every 12 months of operation is recommended.
SAFETY CHECKS
Checks the following:
1)
Burner stoppage by opening the thermostats;
2)
"Blocking" by shading the photoconductive cell.
To unblock push the appropriate button.
