PRESSURISED COLLECTIVE CHIMNEY 3CEp
3CEp installations are available only with the dedicated accessory
(optional).
The B23P/B53P configuration is forbitten in case of installation in
pressurised collective chimney.
Maximum pressure of the pressurised collective chimney must not
exceed the 35 Pascal.
Maintenance in case of pressurised collective chimney must be perfor-
med as indicated in the specific chapter "Maintenance instructions".
For 3CEp installations with dedicated accessory, it is necessary
change the setting of minimum fan speed according the accessory
instructions.
4 - SWITCHING ON AND OPERATION
4.1 Switching on the appliance
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 symbol
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).
Live electrical parts (230 V AC).
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
+ and -, the boiler provides domestic hot water and heating. If there is a heat
request, the boiler switches on. 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.
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 + and -.
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 temperature
is automatically chosen by the system which rapidly adjusts ambient tem-
perature to the changes in external temperature.

To increase or decrease the temperature with respect to the value automa-
tically 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: turning the selector to the summer mode symbol
28) activates the traditional domestic hot water only function.
If there is a domestic hot water request, the boiler switches on. The digital
display shows the hot water system temperature, the icon to indicate the
hot water supply and the flame icon (fig. 30).
Pre-heating (faster hot water): turning the domestic hot water tempera-
ture adjustment knob to the
function, the monitor indicates the fixed
water temperature adjustment knob back to the required position.
This function keeps the water in the domestic hot water exchanger hot, to
reduce standby times when a request is made.
The monitor indicates the delivery temperature of the heating water or
the domestic hot water, according to the current request. During burner
ignition following a pre-heating request, the monitor indicates the flashing
symbol and the flame icon.
To deactivate the pre-heating function, rotate the domestic hot water tem-
perature adjustment knob back to the
water temperature adjustment knob back to the required position.
This function cannot be activated when the boiler is OFF: function selector
(fig.32) to (OFF).
Adjustment of the domestic hot water temperature
To adjust the domestic hot water temperature (bathrooms, shower, kitchen,
etc.), turn the knob with the
the temperature and anticlockwise to reduce it.
The boiler is standby status until, after a heat request, the burner switches
on. 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 symbol (fig. 34) on the control panel lights up, this means the
boiler is in temporary shutdown status (see the chapter on "Light signals
and faults"). The digital monitor indicates the fault code detected (fig. 34).
Automatic Temperature Control System function (S.A.R.A.) fig. 35
Setting the heating water temperature selector to the area marked "AUTO"
(temperature range 55 to 65°C), activates the automatic temperature con-
trol system: according 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.
Reset function
To restore operation, set the function selector to
onds then set the function selector to the required position.
N.B. If the attempt to reset the appliance does not activate operation, con-
tact the Technical Assistance Service.
4.2 Switching off
