Initial operating procedures
If the boiler is installed inside the apartment, make
sure that all provisions relating to the air inlet
and room ventilation (in compliance with current
legislation) are respected.
Check the water pressure on the pressure gauge
regularly and make sure that the gure is between
0.6 and1.5 bar when the system is cold. If the
pressure is just under the minimum value, reestablish the correct pressure by lling loop.
If the pressure drops very frequently, there may be a
water leak at some point in the system. If this is the
case a plumber should be contacted
Ignition procedure
Press the ON/OFF button on the control panel to
switch on the boiler.

The green led 3 will illuminate indicating that the
boiler is ready to operate.
The electronic control unit will ignite the burner,
without any manual intervention but in response
to the request for Domestic Hot Water or heating. If,
after approximately 10 seconds, the burner has not
ignited, the boilersafety devices will shut o the gas
and the red Led 8 illuminates. To reset the ignition
system, the Reset button must be pressed and
released.
Should the boiler fail toignite a second time, check
that the external gas cock is open. If the problem
persists, contact an Authorised Service Centre.

In the “winter” operating mode, the boiler will produce both Central Heating and Domestic Hot Water. In
the “summer” operating mode, the boiler will produce only Domestic Hot Water. Using the knob on the
control panel, the user can select “winter” or “sum-
mer” operating mode. Keeping the knob 5 at the
position selects the “summer” operating mode. “Winter” operating mode may be selected by positioning
the knob 5 between the min. and max. settings.
Adjusting the heating
It is possible to set the temperature of the heating
water by adjusting the knob 5. By positioning the
indicator somewhere between min. and max., a
temperature may be obtained which varies from
about 40°C to about 82°C.
The water temperature in the primary circuit may be
checked by means of the green leds 1.
Domestic hot water temperature adjustement
It is possible to set the temperature of the domestic hot water by adjusting the knob 6 a temperature
may be obtained which varies from about 36°C to
about 60°C.

Boiler protection devices
The boiler is protected from malfunctioning by
means of internal checks performed by the electronic
microprocessor P.C.B., which stops the boiler from
operating if necessary.
In the event of the boiler being shut o in this
manner, the leds code show the type of shut-o and
the reason behind it.
There are two types of shut-o:
Safety shut-o
This type of error is “volatile”, which means that the
boiler starts up again automatically as soon as the
problem which caused the shut-o is removed; the
yellow led 9 ash and the C.H. Temperature leds 1
indicate the error code. (see table)
In fact, soon as the cause of the shut-o disappears,
the boiler starts up again and continues to operate
normally.
If the boiler still indicates a safety shut-o , switch
it o. Make sure the external electric switch is
in the OFF position, shut o the gas valve and
contact a quali ed technician.
Shutdown due to insucient water circulation
If the green leds 1 ash and the boiler is o , one
possible cause for this stateis an insucient pressure
of water in the system - green leds 40-50 blink. Check
the water pressure on the pressure gauge 4 and make
sure that is between 0.6 and 1.5 bar when the system
is cold. If the pressure is just under the minimum rell
the system by open the valve under the boiler.
If the pressure drops very frequently, there may be a
water leak at some point in the system. If this is the
case a plumber should be contacted.
Operation shutdown
This type of error is “non-volatile”, which means that
it is not removed automatically (the red led 8 will
illuminate and the C.H. Temperature led 1 will indicate
the error code). In this case the boiler does not restart
automatically, but it may be reset by pressing the
button. If the problem manifests itself again
after several attempts to reset the appliance, contact
a qualied technician.
Important
If this shutdown occurs frequently, contact an
authorised service centre for assistance. For
safety reasons, the boiler will allow a maximum
of 5 reset operations to take place in 15 minutes
(individual presses of the button). If the shutdown
is occasional or an isolated event, this is not a
problem.
Temporary shutdown due to defective discharge
of exhaust fumes.
The boiler is tted with safety devices, which in the
event of a defective discharge of exhaust fumes,
automatically interrupts the gas supply, there by
shutting o the boiler.
The shut-o of the boiler is temporary and is
indicated by the illuminationof the yellow led 9 for a
period of about 12 minutes.
Once this time period has passed and the discharge
state of exhaust fumes has returned to normal, the
boiler automatically turns back on.
IMPORTANT! If this situation occurs
frequently, contact an Authorised Service
Centre. So that they may check that the
exhaust fumes are being expelled correctly
and that the area is ventilated properly.
Anti-frost Device.
The anti-frost function acts on the central heating
ow temperature probe, independently from other
regulations, when the electrical supply is turned on.
If the primary circuit temperature is between
3°C and 8°C the pump will run (with the diverter valve switching between central heating and
hot water every 1 minute) until the temperature
reaches > 9°C.
If the ow temperature remains between 3°C and
8°C the pump will continue to run for a maximum of
20 minutes unless a temperature above > 9°C is detected in the central heating ow, after this the the
burner will re (heating position) until a temperature
of > 30°C is detected.
If the central heating ow temperature is < 3°C, the
burner will re (heating position) at minimum power
until the temperature reaches > 30°C, the burner will
go out.
If lockout is caused by overheat the burner will not
re but the pump will continue to run (heating position).
The anti-frost device activates only when (with the
boiler operating correctly):
- the system pressure is correct;
- the boiler is electrically powered;
- there is a supply of gas.
