3.6 Filling the heating system (fig. 13)
Once the hydraulic connections have been carried out, fill the heat-
ing system. This operation must be carried out with cold system
following this instructions:
- turn by two or three turns the automatic relief valve cap (I)
- make sure the cold water inlet tap is open
- turn on the filling tap until the pressure indicated by the water
pressure gauge is between 1 and 1.5 bar.
Once filling is complete, close the filling tap.
The boiler has an efficient air separator so no manual intervention is
needed. The burner switches on only if the air relief phase is finished.
3.7 Emptying the heating system
To empty the system, proceed as follow:
- switch off the boiler
- loose the boiler outlet tap (M)
- empty the lowest points of the system.
3.8 Emptying the domestic hot water
When there is risk of frost, the domestic hot water system must be
emptied in the following way:
- close the main tap of the water mains
- open all the hot and cold water taps
- empty the lowest points.
WARNING
When carrying out the discharge of the safety valve (N), it must be
connected to a suitable collection system. The manufacturer is not
responsible for possible damages due to safety valve operation.
4 IGNITION AND OPERATION
4.1 Preliminary checks
First ignition is carried out by competent personnel from an
authorised Technical Assistance Service Beretta.
Before starting up the boiler, check:
a) that the supply networks data (electric, water, gas) corresponds
to the label data
b) that piping leaving the boiler is covered by thermal insulation
sheath
c) that flue gas extraction and air suction pipes work correctly
d) that conditions for regular maintenance are guaranteed if the
boiler is placed inside or between furniture
e) the seal of the fuel adduction system
f) that fuel capacity corresponds to values requested by the boiler
g) that the fuel supply system has the correct capacity for the
necessary capacity to the boiler and that it has all the safety
and control devices prescribed by current regulations.
4.2 Appliance ignition
To start-up the boiler it is necessary to carry out the following op-
erations:
- power the boiler
- open the gas tap present in the system to allow fuel flow
- turn the mode selector (1 - fig. 1a) to the desired position:
Summer mode: turning the selector to the symbol summer
(fig. 2a) the traditional function of only domestic hot water is acti-
vated. If there is a domestic hot water request the digital display
shows the hot water system temperature, the icon to indicate the
hot water supply and the flame icon
Winter mode: by turning the mode selector within the area mar-
ked (fig. 2b), the boiler provides domestic hot water and heating.
If there is a heat request, the boiler switches on and the digital
monitor indicates the heating water temperature, the icon to in-
dicate heating and the flame icon (fig. 3a). If there is a domestic
hot water request, the boiler switches on and the digital display
shows the hot water system temperature, the icon to indicate the
hot water supply and the flame icon (fig. 4a)
Pre-heating (faster hot water): rotate the domestic hot water
temperature adjustment knob (2 - fig. 1a) to the
(fig. 5a), to activate the pre-heating function. This function
keeps the water in the domestic hot water exchanger hot, to
reduce standby times when a request is made. When the pre-
heating function is enabled, the monitor indicates the delivery

temperature of the heating water or the domestic hot water,
according to the current request. During burner ignition follow-
ing a pre-heating request, the monitor indicates the
(fig. 5b). To deactivate the pre-heating function, rotate the
domestic hot water temperature adjustment knob back to the
symbol. Bring the domestic hot water temperature adjust-
ment knob back to the required position. This function cannot be
activated when the boiler is OFF: function selector (1 fig.1a) on
OFF.
Adjust the ambient thermostat to the required temperature (~20°C)
Adjustment of domestic hot water temperature
To adjust domestic water temperature (bathrooms, showers, kitchen, etc.),
turn the knob with symbol
The boiler is standby status until, after a heat request, the burner
switches on and the digital display shows the hot water system tem-
perature, the icon to indicate the hot water supply and the flame icon
The boiler will be in function until the adjusted temperature is
reached, afterwards it will be in "standby" again.
If the red indicator light near the
lights up, this means the boiler is in temporary stop status (see the
chapter about light signals and faults). The digital monitor indicates
the fault code detected (fig. 6a).
Environment Automatic Adjustment System Function (S.A.R.A.)
fig. 7a
By setting the heating water temperature selector to the area marked
by AUTO - temperature value from 55 to 65°C - the S.A.R.A. self-
adjusting system is activated: the boiler varies the delivery tempera-
ture according to the closing signal of the ambient thermostat. When
the temperature set with the heating water temperature selector is
reached, a 20 minutes count begins. If during this period the ambi-
ent thermostat still requests heat, the value of the set temperature
automatically increases by 5 °C.
When the new value is reached, other 20 minutes count begins.
If during this period the ambient thermostat still requests heat, the
value of the set temperature automatically increases by 5 °C.
This new temperature value is the result of the temperature set manu-
ally with the heating water temperature selector and the increase of
+10 °C of the S.A.R.A function.
After the second cycle the temperature value should be kept at the set
value +10°C until the request of the ambient thermostat is satisfied.
4.3 Switching off
Temporary switching off
In case of absence for short periods of time, set the mode selector
(1 - fig. 1a) to
In this way (leaving the electricity and fuel supplies enabled), the
boiler is protected by the following systems:
- Anti-frost device: when the temperature of the water in the boiler
falls below 5°C, the circulator and, if necessary, the burner are
activated at minimum output levels to bring the water temperature
back to the values for safety (35°C). During the anti-frost cycle,
the symbol appears on the digital monitor.
- Circulator anti-blocking function: an operation cycle is activated
every 24 hours.
Long period switching off
In case of absence for long periods of time, set the mode selector
(1 - fig. 1a) to
Then, close the gas tap present on the system. In this case, anti-frost
device is deactivated: empty the systems, in case of risk of frost.
