Switching On And Operation - Beretta Ciao Green 25 C.S.I. Installer And User Manual

1. Ø80 check valve kit with integrated siphon
- Install the split PP system kit.
- Mount the check valve (A) on the flue gas exhaust reduction (B)
previously mounted on the concentric outlet of the air box.
b
DO NOT fasten the check valve to the flue exhaust reduction with
screws. The piercing of the valve would cause the lack of tightness of
the integrated siphon, with consequent leakage of condensate and/
or fumes into the environment.
b
The installation of the check valve requires the application of the
label 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.
A
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.
b
The installation of the check valve requires the application of the
label 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
b
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.
B
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
minutes. During this phase the symbol
25). To interrupt the automatic purge cycle proceed as follows:
access the electronic board by removing the housing, turning the instrument
panel towards you and opening the board casing (fig. 16).
Then:
- using a small screwdriver included, press the CO button (fig. 26).
b
Live electrical parts.
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
temperature to the changes in external temperature.
To increase or decrease 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: 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 temperature
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
temperature adjustment knob back to the
hot 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
