INSTALLING ON BOYLER
1) Lock the flange B on the tube of the burner via the supplied screw A and nut C (n° 2 x BTL 20).
2) Position the insulating seal E on the tube, interposing the cord F between flange and seal.
3) Finally, fix the burner to the boiler via the 4 stud bolts and relative nuts (supplied).
N.B. Make sure the tube penetrates into the combustion chamber as per the boiler manufacturer's
instructions.
PREPARATIONS FOR START UP
Control that the nozzle 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 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. Upon completion of the pre-ventilation time, the solenoid valve is
activated. the electrovalve 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
0002901310). 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".
IGNITION AND ADJUSTMENT
Loosen the lock screw "C" (see 0002934112); act on the screw "A"; bring the air regulation damper into the necessary position as
indicated by index "B". Turn the main switch to ON to power the burner and thus ignite it. Correct, if necessary, combustion air delivery
by acting on the intake damper and the position of the deflector disk (adjustable via screw D). The burner is, in fact, fitted with a special
screw to adjust the position of the deflector disk; this device allows for optimisation of combustion by reducing or increasing the air
flow between deflector disk and head. It is normally necessary to reduce the air flow between deflector disk and head when there is
reduced fuel delivery: this passage must be proportionately more open when the burner is working with a higher fuel delivery rate. After
modifying the position of the deflector disk it is, usually, necessary to correct the air damper positions and afterwards check for proper
ignition.
