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
- set the mode selector (1) to summer (reference notch on symbol)
or winter (reference notch on graduated zone) depending on the season
(fig. 5)
Adjust ambient thermostat to desired temperature (approximately 20°C)
Adjustment of the heating water temperature (1)
With changes in outside temperature it may be necessary to increase or
lower the temperature of the heating water by re-adjusting the selector of
the boiler heating water temperature.
Turn clockwise to increase water temperature and anti-clockwise to lower it.
Adjustment of domestic hot water temperature (2)
The hot water temperature can be changed by turning the hot water ther -
mostat clockwise to increase the temperature and anti-clockwise to lower it.
Pre-heating (faster hot water): rotate the domestic hot water temperature
adjustment knob (2 - fig. 3) to the symbol , to activate the pre-heating
function. This function keeps the water in the domestic hot water exchanger
hot, to reduce standby times when a request is made. When the pre-heating
function is enabled, the yellow LED (1) is ON. The monitor (5 - fig. 9) in -
dicates 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 symbol. 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 dome -
stic hot water temperature adjustment knob back to the required position.
This function cannot be activated when the boiler is OFF: function selector
on OFF (fig. 4).
CTR Function
By setting the heating water temperature selector in the zone marked by the
symbols in bold type, the CTR self-adjusting system is activated (frequency
0.1 sec. on; 0.1 sec. off; duration 0.5): according to the temperature set on
the ambient thermostat and the time employed to reach it, the boiler varies
automatically the heating water temperature reducing the operating time,
allowing great operation comfort and energy saving.
On the control panel, the green led flashes with frequency 0.5 second on,
3.5 seconds off. The boiler is standby status until, after a heat request, the
burner switches on and the indicator turns fixed green to indicate flame
presence. The boiler will be in function until the adjusted temperature is
reached, afterwards it will be in “stand-by” again. If faults arise in ignition
or operations, the boiler performs a “SAFETY STOP”: on the control panel,
the green indicator will switch off and the boiler lockout red indicator will
switch on (see chapter light signals and faults).
Reset function
To restore operation set the mode selector to (fig. 4), wait 5-6 seconds
and then take the mode selector to the desired position checking that the
red indicator light is off. At this point the boiler will automatically start and
the red lamp switches on in green.
N.B. If the attempt to reset the appliance does not activate operation, contact
the Technical Assistance Service.
3A SWITCHING OFF
Temporary switching off
In case of absence for short periods of time, set the mode selector to
OFF (fig. 4). Anti-frost device remains active.
Long period switching off
In case of absence for long periods of time, set the mode selector to
OFF (fig. 4). Then, close the gas tap present on the system. In this case,
anti-frost device is de activated: empty the systems, in case of risk of frost
4A CONTROLS
Make sure at beginning of heating period and during use that the water
pressure gauge indicates the pressure values with cold appliance within
0.6 and 1.5 bar: this avoids system noise levels due to the presence of air.
In case of insufficient water circulation, the boiler will switch off. Under no
circumstances, water pressure must be below 0.5 bar.
If this condition is checked, it is necessary to restore water pressure in the
boiler proceeding as follows:
- set the mode selector (fig.4) to OFF
- open the filling tap (B fig. 26) until the pressure value is within 1 and 1.5
bar.
Carefully close the tap.
Replace the mode selector on the initial position.
If pressure drop is frequent, contact the Technical Assistance Service.
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.
This boiler may only be installed and serviced by qualified personnel
who comply with the national and local current 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.
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: pro -
gram 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 discon
-
nected 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 malfun-
ctioning.
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 aes -
thetic 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 con -
nected to a programming clock in order to manage ignition and switching
off during the day or week.
