PREPARATIONS FOR START UP
Control that the nozzle (6O° 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 1O.200 Kcal).
Make sure that the return 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 drawing). 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
Loosen the clamp screw (see 0002931131) and put the air shutter regulator in the position considered necessary
in function with the quantity of fuel to be burned. Close the main switch in order to start up the burner. Correct, if
necessary, the combustion air delivery by adjusting the suction regulator and the position of the flame disk
(adjustable by operating screw D - see the relevant drawing). The burner is equipped with screws which
regulate the flame disk position and this device permits a perfection of the combustion by reducing or increasing
the air passage between the disk and the head.
It is normally necessary to reduce (turn in a clockwise direction screw D) the air pasasge between the disk and
the head when operating with a reduced fuel delivery. This passage must be proportionately opened more
(turn screw D in an anti-clockwise direction) when the burner is working with a higher fuel delivery.
After having modified the flame disk position, it is normally necessary to correct the air shutter regulator
positions and, subsequently, verify if ignition occurs correctly.
The burner model SPARK 3 is supplied with a device which heats the light oil at the nozzle. This heater helps
to, provide better atomization and therefore better combustion.
