BOILER FIXING
Remove 4 screws (1), insert the
flange (2) and tighten screws (1)
again. Insert the insulating gasket
(3) (if necessary increase the holes
as shown in fig. 2) and fix the burner
to the boiler, (see fig. 3).

PRIMING PUMP
On the system in fig. 5 it is sufficient to loosen the suction gauge
connection (8, fig. 4) and wait until oil flows out.
On the systems in fig. 6 and 7 start the burner and wait for the priming.
Should lock-out prior to the arrival of the fuel, await at least 20 seconds before
repeating the operation.
The pump suction should not exceed a maximum of 0.4 bar (30 cm Hg).
Beyond this limit gas is released from the oil. Oil pipes must be completely
tight. In the vacuum systems the return line should terminate within the oil tank
at the same level as the suction line. In this case a non-return valve is not
required.
Should however the return line arrive over the fuel level, a non return valve is
required. This solution however is less safe than previous one, due to the
possibility of leakage of the valve.
It is necessary to install a filter on the fuel supply line.
H= difference of level; L= max. lenght of the suction line; I.D. = internal diameter.

OBefore starting the burner make sure that the return
pipe-line is not clogged. An excessive back pressure
would cause the damage of the pump seal.
OThe pump is designed for operation on a two line sys-
tem. In order to convert it for single line system it is
necessary to unscrew the return plug (2), remove the
by- pass screw (3) and then to tighten the plug (2)
(see fig. 4).

– Disconnect the oil pipe fitting (1) from the pump. Take out the
photoresistance (2), loosen the retainer screws (3) of the cover.
– Remove the nozzle holder assembly after turning and sliding it
out. The nozzle holder assembly must stay on the left side of the
burner during its sliding.

– Remove the protection crankcase (8,
fig. 1, page 1) after removing the 3
retainer screws. Widen the upper slit
and remove the protection crankcase,
inserting the oil pipe and the flexible oil
lines.
– Insert PG 13.5 cable-gland (1) into the
wire access hole and tighten it with the
nut.
– Insert the electrical cable into the con-
nector and make electrical connec-
tions as shown in fig. 9.
– Put the protection crankcase back in
place.
TESTING:
Check the shut-down of the burner by
opening the thermostats and the lock-out
by darkening the photoresistance.
TO REMOVE THE CONTROL BOX FROM
THE BURNER PROCEED AS FOLLOWS:
– Take out the photoresistance (2, fig. 8).
– Remove the nozzle holder assembly
(see fig. 8).
– Remove the protection crankcase
(8, fig. 1, page 1), as above men-
tioned.
– Disconnect the main voltage cable
(3, fig. 9).
– Remove screws (2, fig. 9) and discon-
nect wires of motors, photoresistance
and coil.

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, including 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, choose the proper nozzle and adjust the pump pressure, the setting of
the combustion head, 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.
PUMP PRESSURE: 12 bar, the pump leaves the factory set at this value.
RECOMMENDED NOZZLES: Delavan type W -B; Danfoss type S - B; Monarch type R; Steinen type S - Q.

COMBUSTION ADJUSTMENT
– Remove the nozzle holder assembly from the
burner (see page 3).
– Remove the diffuser-disc assembly (1) from the
nozzle holder (2) after loosening the screw (3).
– Insert the proper nozzle (6) into the nozzle holder
and tighten securely.
– REPLACE THE DIFFUSER-DISC ASSEMBLY (1)
AND INSERT IT IN THE NOZZLE HOLDER (2)
UNTIL THE END. LOCK WITH SCREW (3).
– Remove the nozzle holder assembly (see page 3).
– Loosen the screw (4), move the electrodes assem-
bly (5) and lock the screw (4).
It depends on the output of the burner and is carried
out by rotating clockwise or counterclockwise the set-
ting screw (1) until the set-point marked on the regu-
lating rod (2) is level with the outside plane of the
nozzle holder assembly (3).Loosen the screw (1) and move the indicator towards
the required set-point and then lock the screw (1).
