any damage to persons, animals or property due to errors in
installation, calibration, maintenance or due to improper use.
The safety and automatic adjustment devices must not be
modified, during the system life cycle, by the manufacturer or
supplier.
This appliance produces hot water, therefore it must be
connected to a heating system and/or a domestic hot water
mains, compatible with its performance and output.
In case of water leakage, close the water supply and contact
the Technical Assistance Service immediately.
In case of absence for long periods time, close the gas supply
and switch off the electrical supply main switch. In case of
risk of frost, empty the boiler.
From time to time check that the operating pressure of the
hydraulic system does not decrease under 1 bar.
In case of failure and/or malfunctioning, deactivate the
appliance, and do not try to repair or intervene directly on it.
Appliance maintenance must be carried out at least once a
year: program it with the Technical Assistance Service will
avoid wasting time and money.
The ventilation openings are vital for correct combustion.
When the product reaches the end of its life it should not be
disposed of as solid urban waste but should be brought to a
separated waste collection facility.
Boiler use requires to strictly observe some basic safety rules:
Do not use the appliance in any manner other than its
intended purpose.
It is dangerous to touch the appliance with wet or damp body
parts and/or in bare feet.
Under no circumstances cover the intake grids, dissipation
grids and ventilation vents in the installation room with cloths,
paper or any other material.
Do not activate 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 gas
central tap.
Do not place anything in the boiler.
Do not perform any cleaning operation if the appliance is not
disconnected from the main power supply.
Do not cover or reduce ventilation opening of the room where
the generator is installed.
Do not leave containers and inflammable products in the
installation room.
Do not attempt to repair the appliance in case of failure and/
or malfunctioning.
It is dangerous to pull or twist the electric cables.
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.
Do not intervene on sealed elements.
Do not cover or reduce the size of the ventilation openings
in the room where the boiler is installed. The ventilation
openings are vital for correct combustion.
For better use, remember that:
- a periodic external cleaning with soapy water not only improves
its aesthetic aspect but also preserves panelling from corrosion,
extending its life cycle;
- if the wall-mounted boiler is enclosed in pendant furniture, leave
at least 5 cm for ventilation and maintenance;
- installation of an room thermostat will favour a greater comfort, a
more rational use of the heat and energy saving; the boiler can
also be connected to a programming clock in order to manage
ignition and switching off during the day or week.
2A IGNITION
First ignition must be carried out by personnel from the Technical
Assistance Service. At the same time, if it is necessary to put the
appliance in service again, carefully follow the described operations.
To start-up the boiler it is necessary to carry out the following
operations:
- power the boiler
- open the gas tap present in the system to allow fuel flow
- turn the mode selector (2 - 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 activated. 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
marked + and - (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 indicate 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)
- adjust the room 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
marked + and -.
The boiler is standby status until, after a heat request, the burner
switches on and the digital display shows the hot water system
temperature, 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.
Environment
Automatic
(S.A.R.A.) - fig. 6a
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 temperature according to the closing signal of the room
thermostat. When the temperature set with the heating water
temperature selector is reached, a 20 minutes count begins. If
during this period the room 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 room 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
manually with the heating water temperature selector and the
increase of +10 °C of the S.A.R.A function.
After the second increasing cycle, the temperature value is restored
to the value set by the user and the above mentioned cycle is
repeated until the ambient thermostat request is fulfilled.
