INSTALLATION
BOILER FIXING
➣ Put on the flange (1) the screw and two nuts, (see fig. 2).
➣ Widen, if necessary, the insulating gasket holes (5), (see fig. 3).
➣ Fix the flange (1) to the boiler door (4) using screws (2) and (if necessary) the nuts (3) interposing the
insulating gasket (5), (see fig. 4).
MAINTENANCE POSITION
Access to the combustion head, diffuser disc / electrodes unit and nozzle, (see fig. 5).
➣ Remove the burner out of the boiler, after loosing the fixing nut to the flange.
➣ Hook the burner to the flange (1), by removing the combustion head (6) after loosing the fixing screws (7).
➣ Remove the diffuser disc-holder assembly (9) from the nozzle-holder (8) after loosing its fixing screw.
➣ Screw the nozzle (10).

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.
◆ Check periodically the flexible pipes conditions. Using kerosene, they have to be replaced at
least every 2 years.
◆ A metal bowl filter with replaceable micronic filter must be fitted in the oil supply pipe.

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
carried out by rotating the regulating rod, till the terminal
plane of the blast tube is level with the set-point, as indi-
cated in the schedule.
