Installation
4.7 Securing the burner to the boiler
Before securing the burner to the boiler, check (through the
opening of the blast tube) that the probe and electrode are
correctly positioned, as in Fig. 16.
Separate the combustion head from the rest of the burner,
(Fig. 12):

loosen the 4 screws 3) and remove the cover 1).

Disengage the articulated coupling 7) from the graduated
sector 8).

Remove the screws 2) from the two slide bars 5).

Remove the two screws 4) and pull the burner back on slide
bars 5) by about 100 mm.

Disconnect the probe and electrode cables, then completely
unthread the burner from the slide bars.

Fix the flange 11) to the plate of the boiler interposing the
insulating gasket 9) supplied.
Use the 4 screws, also supplied, after protecting their thread
with an anti-locking product.
4.8 Calibration of the thermal relay
The thermal relay serves to avoid damage to the motor due to an
excessive absorption increase or if a phase is missing.
For calibration 2), see the table in the wiring diagram.
To reset, in case of an intervention of the thermal relay, press the
"RESET" button 1) of Fig. 13.
The red “TEST” button 3) opens the NC (95-96) contact and
stops the motor.
4.9 Motor rotation
As soon as the burner starts, place yourself in front of the cooling
fan of the fan motor and check that it turns anticlockwise
(Fig. 14).
If this is not the case:

put the switch of the burner to “0” (off) and wait until the
control box carries out the switching off phase.

Invert the phases on the three-phase motor power supply.
Provide an adequate lifting system of the burner.
ATTENTION
The burner-boiler seal must be hermetic; after
burner start-up check there is no leakage of flue
gases into the external environment.
