At this point it is possible to install the curves and extensions, available as
accessories, depending on the type of installation desired.
2. Ø80/125 check valve kit with integrated siphon
- Install the adapter from Ø60/100 to Ø80/125, with flue pipe in PP, on the
concentric outlet of the air box.
- Mount the check valve (C) on the adapter (D) previously mounted on the
concentric outlet of the air box.
The installation of the check valve requires the application of the la-
bel supplied with the kit on a visible part of the boiler casing. The
application of the label is essential for safety purposes during the
maintenance or replacement of the boiler and/or collective pipe.
At this point it is possible to install the curves and extensions, available as
accessories, depending on the type of installation desired.
With C(10) installation, in any case, register the fan speed (rpm) on the
label on the side of the product serial number.
4 - SWITCHING ON AND OPERATION
4.1 Switching on the appliance
The first time you turn the boiler on and in case of maintenance work,
before using the appliance you must fill the siphon with water and
make sure that the condensation is evacuated correctly.
Fill the condensation collection siphon pouring 1 litre of water into the
boiler combustion-analysis outlet with the boiler off, and check that:
- the safety cut-off device is floating
- water is flowing correctly from the discharge pipe out of the boiler
- the condensate outlet connection line is watertight
If the condensate outlet circuit (siphon and pipes) is working correctly, the
condensation level will not exceed the maximum. Filling the siphon before
using the appliance, and the use of a safety cut-off device inside the siphon,
prevent exhaust gases from being released into the environment.
Repeat during standard and non-standard maintenance work.
Every time the appliance is powered up, a series of data is shown on the
display including the flue gas sensor meter reading (-C- XX) (see paragraph
4.3 - fault A09); the automatic purge cycle then starts, lasting around 2 min-
utes. During this phase, the three LEDs light up alternately and the symbol
is shown on the monitor (fig. 25).
To interrupt the automatic purge cycle proceed as follows:
access the electronic board by removing the housing, turning the instru-
ment panel towards you and opening the board casing (fig. 16).
Then:
- using a small screwdriver included, press the CO button (fig. 26).

To start up the boiler it is necessary to carry out the following operations:
- power the boiler
- open the gas tap to allow the flow of fuel
- set the room thermostat to the required temperature (~20°C)
- turn the mode selector to the desired position:
Winter mode: by turning the mode selector (fig. 27) within the area marked
with segments, the boiler provides hot water for heating and, if connected
to an external storage tank - supplies hot water for DHW.
If there is a heat request, the boiler switches on and the boiler status indica-
tor LED lights up with a fixed green light. The digital monitor indicates the
heating water temperature, the icon to indicate heating and the flame icon
(fig. 29).
If there is a domestic hot water request, the boiler switches on and the
boiler status indicator LED lights up with a fixed green light.
The digital display shows the hot water system temperature, the icon to
indicate the hot water supply and the flame icon (fig. 30).
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the knob with symbol
(fig. 27) within the area marked with segments.
Depending on the type of system, it is possible to pre-select the suitable
temperature range:
- standard systems 40-80°C
- floor systems 20-45°C.
For further details, consult the "Boiler configuration" section.
Adjusting heating water temperature with an external probe connected
When an external probe is connected, the value of the delivery tempera-
ture is automatically chosen by the system which rapidly adjusts ambient
temperature to the changes in external temperature. To increase or decre-
ase the temperature with respect to the value automatically calculated by the
electronic board, turn the heating water selector clockwise to increase and
anticlockwise to decrease. Adjustment settings range from comfort levels - 5
to + 5 which are indicated on the digital display when the knob is turned.
Summer mode (only active when the external storage tank is
connected): turning the selector to the summer mode symbol
28) activates the traditional domestic hot water only function, the boiler
supplies water at the temperature set on the external storage tank.
If there is a domestic hot water request, the boiler switches on and the
boiler status indicator LED lights up with a fixed green light. The digital di-
splay shows the hot water system temperature, the icon to indicate the hot
water supply and the flame icon (fig. 30).
Adjustment of the domestic hot water temperature
CASE A heating only with storage tank - adjustment does not apply.
CASE B heating only + external storage tank with thermostat - adjustment
does not apply.
CASE C heating only + external storage tank with probe - to adjust the
temperature of the domestic hot water in the storage tank, turn the knob-but
with the symbol (fig. 32) clockwise to increase water temperature and
anti-clockwise to lower it.
On the control panel, the green LED flashes with ON for 0.5 seconds, OFF
for 3.5 seconds.
The boiler is standby status until, after a heat request, the burner switch-
es on and the indicator LED turns fixed green to indicate flame presence.
The boiler continues to operate until the temperatures set on the boiler are
reached, or the heat request is met; after which it goes back on standby.
If the red LED indicator near the
lights up, this means the boiler is in temporary shutdown status (see chap-
ter "Light signals and faults").
The digital monitor indicates the fault code detected.
Automatic Temperature Control System function (S.A.R.A.) fig. 34
Setting the heating water temperature selector to the area marked "AUTO"
(temperature range 55 to 65°C), activates the automatic temperature con-
trol system (frequency 0.1 sec. on; then 0.1 sec. off; for 0.5 seconds): ac-
cording to the temperature set on the room thermostat and the time taken
to reach it, the boiler varies automatically the heating water temperature
reducing the operating time, allowing greater ease of operation and energy
saving. On the control panel, the green LED flashes ON for 0.5 seconds,
OFF for 3.5 seconds.
Reset function
To restore operation, set the function selector to
onds then set the function selector to the required position, checking that
the red indicator light is OFF.
At this point the boiler will automatically start and the red lamp switches on
in green.
NOTE: If the attempt to reset the appliance does not activate operation,
contact the Technical Assistance Service.
