PREPARATIONS FOR START UP

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.
Should it be necessary to purge air, this can be done by
!
loosening the special fitting which the pump is provided
with. 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".

After having installed the nozzle, check the correct position of
the electrodes and disk according to the following levels. It's
adviseable to check levels after every intervention on head.
To prevent damage to the support or the pre-heater
!
effect nozzle assembly/disassembly tasks with the
aid of a wrench and counter-wrench.

IGNITION AND ADJUSTMENT

Check that there is no electrical connection (bridge) between the
2nd flame thermostat terminals and that this thermostat is not
connected. Operate the 1st flame air regulation screw to put the
shutter which regulates the air for the first flame in the position
considered necessary to allow for a flow of air in proportion to the
amount of fuel delivered for the 1st flame (see 8920/2 and 8943/1).
Close the main switch in order to connect the burner, and wait for
it to start up. With the burner operating at the 1st flame, correct, if
necessary, the combustion air delivery by operating the regulating
cam of the 1st flame. After regulating the air, disconnect the burner
and re-connect it again to make sure that ignition occurs correctly.
It should be remembered that, normally, the quantity of air required
for a soft ignition is the minimum indispensable. If ignition occurs
softly, disconnect the burner from the main switch and make a
direct connection (bridge) between the 2nd flame thermostat
terminals. By operating the cam, regulate the combustion air to
the extent considered necessary for the insertion of the 2nd flame
(see 8920/2 and 8943/1).
Now re-connect the burner and it will start operating with the 1st
flame. Operate the air regulation cam of the 2nd flame in order to
obtain the quantity of air considered necessary for the specific
conditions. The burner is supplied with regulating screws for the
flame disk position and this device permits a perfection of the
combustion by reducing (tight the screw n°2), or increasing (untight
the screw n°2), the air passage between the disk and the head. It
is normally necessary to reduce the air passage between the disk
and the head when operating with a reduced fuel delivery. This
passage must be proportionately opened more when the burner is
working with a higher fuel delivery (see 0002933230). After having
modified the flame disk position, it is usually necessary to correct
the air regulation shutter positions of the 1st and 2nd flame, and
subsequently, verify that ignition occurs correctly.
