Boiler use requires strict observation of some basic safety rules:
a
Do not use the appliance in any manner other than its intended
purpose.
a
It is dangerous to touch the appliance with wet or damp body parts
and/or when barefoot.
a
Under no circumstances cover the intake grids, dissipation grids and
ventilation vents in the installation room with cloths, paper or any
other material.
a
Do not use electrical switches, telephone or any other object that
causes sparks if there is a smell of gas. Ventilate the room by opening
doors and windows and close the central gas tap.
a
Do not place anything in the boiler.
a
Do not perform any cleaning operation if the appliance is not
disconnected from the mains power supply.
a
Do not cover or reduce ventilation opening of the room where the
generator is installed.
a
Do not leave containers and inflammable products in the installation
room.
a
Do not attempt to repair the appliance in case of failure and/or
malfunctioning.
a
It is dangerous to pull or twist the electric cables.
a
Do not access the inside of the boiler. Any work on the boiler should
be carried out by the Technical Assistance Centre or by professionally
qualified personnel.
a
Do not carry out operations on sealed elements.
For better use, remember that:
- periodic external cleaning with soapy water not only improves its appear-
ance but also preserves panelling from corrosion, extending its life cycle;
- if the wall-mounted boiler is enclosed in a hanging unit, leave at least 5
cm for ventilation and maintenance;
- installation of a room thermostat will greatly improve comfort, a more ra-
tional use of the heat and energy saving; the boiler can also be connected
to a programmable timer in order to control the switching on and off of the
appliance during the day or week.
2a 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
4a - fault A09); the automatic purge cycle then starts, lasting around 2 min-
utes. During this phase the symbol
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 -.
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
monitor indicates the domestic hot water 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 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",
activates the automatic temperature control system: according to the tem-
perature set on the room thermostat and the time taken to reach it, the
boiler varies automatically the heating water temperature reducing the op-
erating time, allowing greater ease of operation and energy saving.
