operation must be carried out by qualified personnel
according to current local and national regulations.
For installation, it is advisable to contact specialised personnel.
The boiler must only be used for the application foreseen by
the manufacturer. The manufacturer shall not be liable for
any damage to persons, animals or property due to errors in
installation, calibration, maintenance or due to improper use.
This appliance should not be operated by children younger
than 8 years, people with reduced physical, sensory or
mental capacities, or inexperienced people who are not
familiar with the product, unless they are given close
supervision or instructions on how to use it safely and are
made aware by a responsible person of the dangers its use
might entail. Children must not play with the appliance. It is
the user's responsibility to clean and maintain the appliance.
Children should never clean or maintain it unless they are
given supervision.
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
(3 - 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 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. 4a)
.
Winter mode:
by turning the mode
selector
within the
area marked (fig. 2b), the boiler provides domestic hot water and
heating. If there is a heat request, the boiler switches on and
the
boiler status indicator 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. 3a). 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.
T
he digital display
shows the hot water system temperature, the icon to indicate the
hot water supply and the flame icon (fig. 4a)
Pre-heating (faster hot water)
: turning the domestic hot
water temperature adjustment knob (4 - fig. 1a) to the
symbol (fig. 5a), to activate the pre-heating function. This
function keeps the water in the domestic hot water exchanger
hot, to reduce stand-by times when a request is made. When
the pre-heating function is enabled, the yellow LED next to
the
symbol is lit.
The digital display 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 display indicates the
symbol
(fig. 5b). To deactivate the pre-heating function, rotate the
domestic hot water temperature adjustment knob back to the
symbol. T
he yellow LED will switch off. Bring the domestic hot
water temperature adjustment knob back to the required position.
This function cannot be activated when the boiler is OFF: function
selector (fig.6b) on OFF.
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the knob with symbol
(within the area divided into segments fig. 2b).
Adjustment of domestic hot water temperature
To adjust domestic water temperature (bathrooms, showers, kitchen,
etc.), turn the knob with symbol (fig. 8a) within the area marked 1 and
6. Rotate clockwise to increase the temperature and anticlockwise
to reduce it.
On the control panel, the green LED flashes with ON
for 0.5 seconds, OFF for 3.5 seconds.
The boiler is stand-by status
until, after a heat request, the burner switches on and the
indicator
LED turns fixed green to indicate flame presence. 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.
If the red LED indicator light near the
symbol on the control panel
lights up, this means the boiler is in temporary stop status (see
chapter "Light signals and faults"). The digital monitor indicates the
fault code detected (fig. 6a).
