It is necessary that the insulating gasket
(9, fig. 1) is placed between the boiler door
and the burner flange.
This insulating gasket has six holes,
which, if necessary, can be modified as
shown on the drawing on the right.
Verify that the installed
burner is lightly leaned
towards the button.
(See figure 2).

HYDRAULIC SYSTEM
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 air-
tight.
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.
PRIMINGTHE 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.

NOTES
– Wires of 1 mm2section.
– The electrical wiring carried out by the
installer must be in compliance with the
rules in force in the Country.
– To remove the control-box from the
burner, loosen screw (A)
(see figure) and
pull towards the arrow.
– The photoresistance is fitted directly into the
control-box
(underneath the ignition-trans-
former)
on a plug-in support.
TESTING
Check the shut-down of the burner by opening
the thermostats.
ATTENTION
Do not connect burner’s grounding, to failure
indicator terminal .
This may result the destroy of the control box.

COMBUSTION ADJUSTMENT
In conformity with Efficiency Directive 92/42/EEC the application of the burner on the boiler, adjust-
ment and testing must be carried out observing the instruction manual of the boiler, including verifica-
tion 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 and the air damper
opening in accordance with the following schedule.
The values shown in the table are measured on a CEN boiler (as per EN 267).
They refer to 12.5% CO2at sea level and with light oil and room temperature of 20 °C.
RECOMMENDED NOZZLES: Monarch type R - NS; Delavan type W - A - E
Steinen type H - Q ; Danfoss type H - B
Angle: 60° : in most cases.
80° : in case of flame detachment, during ignitions at low tem-
peratures.
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:This is done when fitting the nozzle, with the blast tube
removed.It depends on the output of the burner and is car-
ried 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.

head is set for an output of 0.60 GPH at

dule.

Combustion head settings indicated in the schedule 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) with a 6 mm spanner (2) as follows:
Turn to the right: (sign +), in order to increase the vol-
ume of air entering the combustion chamber and thus
diminishing its pressure.
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 increas-
ing its pressure. 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 setting
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:
The regulation of the air-rate is made by adjusting the air
damper (A), after loosing the screws (B).
When the optimal regulation is reached, screw tight the
screws (B).
The settings indicated in the schedule are purely indic-
ative.
Each installation however, has its own unpredictable
working conditions: actual nozzle output; positive or
negative pressure in the combustion-chamber, the
need of excess air, etc.
All these conditions may require a different air-damper
setting.

BURNER START-UP CYCLE
ADJUSTMENTS,TO AVOID FLAME - DETACHMENT, AT BURNER - IGNITION
This inconvenience can occur, when the temperature of the gas-oil decreases below +8 °C.
1) CORRECT POSITIONING OF THE ELECTRODES
2) NOZZLE: ATOMIZING CONE
Choose empt ies or semi-empt ies cones; Delavan type A - E; Steinen type H; Danfoss type H.
3) PUMP - SETTING
The pump is factory set, at a pressure of 12 bar.
When the temperature of the light oil decreases below +8 °C, increase the pressure to 14 bar.
4) COMBUSTION-HEAD SETTING
Regulate the combustion-head one set-point further ahead than indicated in the instructions.
Example:
the instructions require to set the combustion-head on set-point 2.
Instead, the setting is made on set-point 3.
5) FAN - AIR DAMPER ADJUSTMENT
Adjust the air damper of the fan, such as to obtain a smoke-number not inferior to 1.
(i.e. a combustion with the lowest possible excess-air).
