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.

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
volume of air entering the combustion chamber and
thus diminishing its pressure.
There is a reduction of CO
2
and the adhesion of the
flame to the air diffuser disc improves. (Setting advisa-
ble for ignitions at low temperatures).
Turn to the left: (sign – ), in order to reduce the vol-
ume of air entering the combustion chamber and thus
increasing its pressure. The CO
2
improves and the
adhesion of the flame to the diffuser tends to reduce.
(This setting is not advisable for ignitions at low tem-
peratures).
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 num-
ber of turns.
AIR DAMPER ADJUSTMENT :
The settings indicated in the schedule refer to the burner with its metal cover fitted and the combustion
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-chamber, the need of excess air, etc. All these conditions may
require a different air-damper setting.
It is important to take account of the fact that the
air output of the fan differs according to whether
the burner has its metal cover fitted or not.
Therefore we recommended to proceed as follows:
– adjust the air damper as indicated in the table;
– mount the cover, simply by means of the upper
screw;
– check smoke number;
– should it become necessary to modify the air out-
put, remove the cover by loosening the screw,
adjust the air damper, remount the cover and
finally recheck the smoke number.
NOTE:
When the burner works at a firing rate higher
than 9 kg/h for type 716T81 and 18 kg/h for type
717T81 remove the panel fitted inside the metal
cover. (See figure).

PUMP PRESSURE AND AIR OUTPUT
The burner is provided with an hydraulic device controlled by the economizer which reduces to
approx. 70% the max. output of light oil and air.
1st STAGE ADJUSTMENT
Adjustment of air shutter: place the small plug (9) of the economizer (10) into the position I
(Item A). In this way the burner will remain permanently in the 1
st
stage.
Unloosen the nut (2), turn the screw (3) until the air shutter (1) reaches the position desired.
Then lock the nut (2).
Pressure regulation: this is set at 7 bar at the factory.
Should such pressure be reset or changed, just turn the screw (4). The pressure gauge must be
mounted in place of cap (5).
2nd STAGE ADJUSTMENT
Adjustment of air shutter: place the small plug (9) of the economizer (10) into the position II
(Item B). In this way the burner remains permanently in the 2
nd
stage.
Unloosen the nut (6), turn the screw (7) until the air shutter (1) reaches the position desired. Then
lock the nut (6).
Pressure regulation: this is set at 11 bar at the factory.
Should such pressure be reset or changed, just turn the screw (8). The pressure gauge must be
mounted in place of cap (5).

INSTALACIÓN HIDRÁULICA
Atención: antes de poner en funcionamiento el quemador hay que asegurarse de que el tubo de
retorno del combustible no esté obstruido. Una contrapresión excesiva causaría la rotura
del órgano de estanquidad de la bomba.
No hay que sobrepasar la depresión
máx. de 0,4 bar (30 cm Hg). Por encima
de este valor se produce la gasificación
del combustible.
Las tuberías deben ser perfectamente
estancas. En las instalaciones por de-
presión, la tubería de retorno debe lle-
gar a la misma altura que la de
aspiración. En este caso nose necesita
válvula de pie.
En cambio, si la tubería de retorno llega
por encima del nivel del combustible, la
válvula de pie es indispensable. Esta se-
gunda solución es menos segura que la
precedente debido a la eventual falta de
estanquidad de esta válvula.
CEBADO DE LA BOMBA
Encienda el quemador y espere el ce-
bado. Si el bloqueo del quemador se
produce antes de la llegada del com-
bustible, esperar como mínimo 20 se-
gundos e iniciar de nuevo esta
operación.
◆ Controle periódicamente las condiciones de los tubos flexibles. Cuando se utiliza kerosene estos
se deben sustituir cada 2 años.
◆ Coloque un filtro de taza de metal con filtro micrónico sustituible en el tubo de alimentación de aceite.
ATENCIÓN
La bomba está prevista para funcionar en bitubo.
Para el funcionamiento monotubo se debe quitar el tornillo de
by-pass (A), (ver la figura).
