ELECTRICAL CONNECTION

The electrical lines should be at an adeguate distance from hot
parts.It is advisable to make all the connections with flexible elecric
wire. Conductor's minimun section 1,5 mm
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
E
cause a breakage in the sealing surface situated on the pump shaft.
Close the main switch and the boiler thermostats in order to
N
start up the motor and the ignition transformer. Upon completion
G of the pre-ventilation time, the solenoid valve is activated. the
electrovalve will cut in and expose the photoresistant cell to
L
a source of light until the burner stops (shut down).
When the pipelines have been filled up (and when fuel has come
I
out of the nozzle), stop the burner and put the photoresistant cell
S back in its seat.
NOTE: Should it be necessary to purge air, this can be done by
H
loosening the special fitting which the pump is provided with
(see 0002900480). 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 "A" clamp screw (see draw) and put the air shutter
regulator in the position considered necessary in function with the
quantity of fuel to be burned. Close the main swich in order to start
up the burner. Correct, if necessary, the combustion air delivery by
adjusting the suction regulation (see screw "10").
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 an antidockwise
direction the relative screw) the air passage between the disk and
the head when operating with a reduced fuel delivery. This pas-
sage must be proportionately opened more (turn relative screw in
a clockwise direction) when the burner is working with a highter
fuel delivery.
After having modified the flame disk position, it is normally neces-
sary to correct the air shutter regulator positions and, subsequently,
verify if ignition occurs correctly.
The burner is provided with the pump set at 12 bar, to adjust this
value rotate the relative screw.
