HYDRAULIC JACK OPERATION 7)(Fig. 1)
It is strongly recommended a periodic check of
the pump pressure operation (annually or bet-
ter every six months, if the burner operation is
continuous).
If the value is lower than 1 bar, compared to
that one of the initial setting, please check the
cleaning of the pump and line filters.
In case the pressure setting was not restora-
ble, please replace the pump, in order to guar-
antee that the pump pressure during the pre-
purge time is at least 3.7 bar.

HYDRAULIC SYSTEMS
Warning: before starting the burner make sure that the return pipe-line is not clogged: any obstruc-
tion would cause the pump seals to break.
The pump vacuum should not exceed a
maximum of 0.4 bar (30 cm Hg).
Beyond this limit gas is released from
the oil.
Oil lines must be completely airtight.
The return line should terminate in
the oil tank at the same level as the
suction line; in this case a non-return
valve is not required.
When the return line arrives over the
fuel level, a non-return valve must be
used.
This solution however is less safe than
previous one, due to the possibility of
leakage of the valve.
PRIMING THE PUMP
Start the burner and wait for the priming.
Should lock-out occur prior to the arrival
of the fuel, await at least 20 seconds
before repeating the operation.
A filter must be installed on the suction fuel line.

NOTE:
The burner is provided with a socket for the direct electrical connection to the boiler’s
plug (see diagram at page 5). Should the boiler be without plug, it is then necessary:
– remove the socket and respective cable mounted on the burner;
– carry out the electrical connection direct to the wiring terminal block of the burner as shown on
the diagram below.

COMBUSTION ADJUSTMENT
In conformity with Efficiency Directive 92/42/EEC the application of the burner on the boiler,
adjustment and testing must be carried out observing the instruction manual of the boiler, includ-
ing verification of the CO and CO2concentration in the flue gases, their temperatures and the
average temperature of the water in the boiler.
To suit the required appliance output, fit the nozzle then adjust the pump pressure, the setting of
the combustion head and the air damper opening in accordance with the following schedule.

advisable to use, if possible,
full cones.

PUMP PRESSURE
12 bar : The pump leaves the factory set at this
value.
14 bar : Improves flame retention; it is therefore
suitable for ignitions at low temperatures.
COMBUSTION HEAD SETTING
(see fig. 4 and 5)
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 rotating the regulating
rod, till the terminal plane of the blast tube is level
with the set-point, as indicated in the schedule.
The combustion head is set for an output of 1.50
GPH at 12 bar, while the shutter is level with set-
point 3, as required in the table.
Combustion head settings indicated in the table 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 sub-
sequently want to retouch also the setting of the
combustion head, with the burner running, operate
on the rod (1) 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 pres-
sure. There is a reduction of CO2and the adhesion
of the flame to the 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 pres-
sure. The CO2improves and the adhesion of the
flame to the diffuser tends to reduce. (This setting
is not advisable for ignitions at low temperatures).
In any case do not bring the combustion head set-
ting more than one point away from that indicated
in the schedule. One set-point corresponds to 3
turns of the rod; a hole (3) at its end facilitates
counting the number of turns.
AIR DAMPER ADJUSTMENT (see fig. 6)
The mobile air damper (A) operated by the jack (B) assures the complete opening of the air
intake. The regulation of the air-rate is made by adjusting the fixed air damper (C), after loosing
the screws (D). When the optimal regulation is reached, screw tight the screws (D) to assure a
free movement of the mobile air damper (A).
The settings indicated in the schedule refer to the burner with its metal cover fitted and the com-
bustion chamber with “zero” depression.
These regulations are purely indicative. Each installation however, has its own unpredictable
working conditions: actual nozzle output; positive or negative pressure in the combustion-cham-
ber, the need of excess air, etc. All these conditions may require a different air-damper setting.
