the pump leaves the factory set at this value.
8 bar:
10 bar: maximum pressure for kerosene.

Combustion head adjustment
This is done when fitting the nozzle, with the blast tube removed.
It depends on the output of the burner and is carried out by rotat-
ing the regulating rod, till the terminal plane of the blast tube is
level with the set-point, as indicated in the Tab. F.
Exsemple:
in the sketch on the left, the combustion head is set for an output
of 1.25 GPH at 8 bar, while the shutter is level with set-point 3, as
required by the Tab. F.
Combustion head settings indicated in the Tab. F are valid for
most cases.
The setting of the fan output according to the installation should
normally be done only through the air damper.
Should one subsequently want to retouch also the setting of the
combustion head, with the burner running, operate on the rod
1)(Fig. 15) with a 6 mm spanner 2) as follows:
TURN TO THE RIGHT: SIGN +
In order to increase the volume of air entering the combustion
chamber and thus diminishing its pressure.
There is a reduction of CO

air diffuser disc improves.
(Setting advisable for ignitions at low temperatures).
TURN TO THE LEFT: SIGN –
In order to reduce the volume of air entering the combustion
chamber and thus increasing its pressure.
The CO
improves and the adhesion of the flame to the diffuser
2
tends to reduce.
(This setting is not advisable for ignitions at low temperatures).
In any case do not bring the combustion head setting more than
one point away from that indicated in the Tab. F.
One set-point corresponds to 3 turns of the rod; a hole 3)(Fig. 15)
at its end facilitates counting the number of turns.
