PREPARATIONS FOR START UP
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 cause 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). Do not illuminate the 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
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.
