DISASSEMBLY OF
EXPANSION VESSEL

To disassemble the expansion vessel, pro-
ceed as follows:
– Make sure that the water has been emp-

tied out of the boiler.

– Unscrew the connection and the locknut.
– Remove the expansion vessel.

Before refilling the system, using a pressu-
re gauge attached to the valve make sure
that the expansion vessel is preloaded at a
pressure of 0.8 to 1 bar.

CLEANING AND

MAINTENANCE

Preventive maintenance and checking of
efficient operation of equipment and safety
devices must be carried out exclusively by
authorized technical personnel.

During maintenance operations the
authorised technician must check that
the condensate trap is full of water

(this

check is of importance particularly when
the generator has been out of use for a long
period of time).
Filling is done via the special opening (fig.
25).

4.8.1

Disassembly the control panel
and skirt cover lid

(fig. 26)

To remove the cover, take out the screws
(1 – 2) that hold it in place on the instru-
ment panel. Position side

“A”

of the brack-

et on the skirt side so that the instrument
panel is hooked on the side in order to
facilitate this operation.

4.8.2

Chimney sweep function

To carry out the verification of combustion
in the boiler, turn the selector and stop on
the position ( ) until the orange led (

)

starts to flash intermittently (fig. 27).
From that moment the boiler will start
ignite in heating mode at the maximum
power, switching off at 80°C and restarting
at 70°C.

Before activating the chimney sweep func-
tion make sure that the radiator valves
and any zone valves are open.

The test may be carried out using the hot
water function.
It may be necessary to draw off domestic
water until the cylinder temperature
reduces and the switches on the led (

).

In this condition the boiler ignites at the
maximum output with the primary circuit
controlled between 80°C and 70°C.
During the duration of the testing the hot
water taps must remain open. After verify-
ing the combustion the boiler should be
switched off by placing the selector on the
