2
PUMP PRESSURE
The pump leaves the factory set at 12 bar.
To change it act on pump pressure adjust screw (5, fig.
7, page 4).
3
COMBUSTION HEAD SETTING (see fig. 14)
It depends on the output of the burner and is carried out
by rotating clockwise or counterclockwise the setting
screw (2) until the set-point marked on the regulating
rod (3) is level with the outside plane of the diffuser noz-
zle-holder assembly (1).
– In the sketch the combustion head is set for an output
of 0.65 GPH at 12 bar.
The set-point 3 of the regulating rod (3) is at the same
level with the outside plane of the nozzle-holder
assembly (1) as shown in the schedule.
4
AIR DAMPER ADJUSTMENT (see fig. 14)
To vary the setting adjust the screw (4) after loosing the
nut (5).
When burner shuts down the air damper automatically
closes till a max. chimney depressure of 0.5 mbar.

4.3 POSITIONING OF THE OPTICAL FIBRE,

To position the optical fibre, you must proceed as follows:
. Insert optical fibre (1) in the diffuser disc support assembly (3), making sure it is pushed in all the way.
. Tighten screw (4) carefully to hold optical fibre (1) in place.

ELECTRODES ADJUSTMENT

WARNING
MEASURES MUST BE
RESPECTED.
Lean the diffuser disc-holder as-
sembly (3) on the nozzle-holder
(2) and lock it by screw (4).
For prospective adjustments of
the electrodes assembly (5), loo-
sen screw (6).
To have access to the electro-
des carry out operation as de-
scribed in chapter 4.1 (page 6)
"RECOMMENDED NOZZLES".

FUEL HEATING

In order to assure regular ignition and working also at low temperature the burner has an oil pre-heater fitted in
combustion head. The pre-heater starts when thermostats close.
When the required temperature for ignition is reached the thermostat fitted on the nozzle holder starts the burn-
er. The pre heater remains energised during working and cuts out when burner shuts-down.
