USER
1A GENERAL WARNINGS
The instruction manual is an integral part of the product and it must
therefore be kept carefully and must accompany the appliance; if the
manual is lost or damaged, another copy must be requested from the
Technical Assistance Service.
Boiler installation and any other assistance and maintenance
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 instal-
lation, 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 con-
nected 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.
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.
Children or unskilled persons must not use the appliance.
Do not intervene on sealed elements.
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 ambient 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 opera-
tions.
To start-up the boiler it is necessary to carry out the following op-
erations:
- power the boiler
- open the gas tap present in the system to allow fuel flow
- turn the mode selector (1 - 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 ac-
tivated. 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 mar-
ked (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 in-
dicate 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. The 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 (2 - fig. 1a) to the
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
play 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. The 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 domestic hot water temperature
To adjust domestic water temperature (bathrooms, showers, kitchen, etc.),
turn the knob with symbol
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 tempe-
rature, 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
panel lights up, this means the boiler is in temporary stop status
(see "Light signals and faults"). The digital monitor indicates the
fault code detected (fig. 6a).
Environment Automatic Adjustment System Function (S.A.R.A.,
fig. 7a)
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 green LED flashes (frequency
0.1 sec. on; then 0.1 sec. off; for 0.5 seconds): the boiler varies the
delivery temperature according to the closing signal of the ambient
thermostat. When the temperature set with the heating water tem-
perature selector is reached, a 20 minutes count begins. If during
this period the ambient 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 ambient thermostat still requests heat, the
value of the set temperature automatically increases by 5 °C.
