boilers have a new ACC (active combustion control)
combustion control system. This innovative control system, developed
E\ 5LHOOR JXDUDQWHHV IXQFWLRQDOLW\ HႈFLHQF\ DQG ORZ HPLVVLRQV LQ DOO
circumstances. The ACC system uses an ionization sensor immersed in
WKHEXUQHUÀDPHZKLFKWKURXJKLWVLQIRUPDWLRQDOORZVWKHFRQWUROERDUG
to act on the gas valve that regulates the fuel. This sophisticated control
system allows self-regulation of combustion, eliminating the need for ini-
tial calibration. The ACC system is able to adapt the boiler to operate with

(within the expected design limits). The ACC system is also able to carry
out a self-diagnosis which blocks the burner before exceeding emission
thresholds higher than the limits allowed by the regulations.

In the case of a new installation or replacement of the boiler, it is nec-
essary to clean the heating system. To ensure the device works well,
top up the additives and/or chemical treatments (e.g. anti-freeze liquids,

The boiler must be connected to a heating system and a DHW network
both sized according to its performance and output.
Before installation, wash all system piping carefully in order to remove
any residues that may impair the operation of the appliance.
Under the safety valve, install a water collecting funnel with the
corresponding discharge in the event of leaks due to the overpressure
of the heating system. The domestic hot water circuit does not need a
safety valve, but make sure that the pressure of waterworks does not
exceed 6 bar. In case of doubts, install a pressure reducer.

ANTI-FREEZE SY
STEM
The boiler comes as standard with an automatic anti-freeze system,
which activates when the temperature of the primary circuit water
drops below 5°C. This system is always active and provides protec-
tion for the boiler up to an air temperature in the installation area of
>0°C.
b To take advantage of this protection (based on burner opera-
tion), the boiler must be able to switch itself on; any lockout
condition (e.g. a lack of gas or electricity,
or the intervention of a
safety device) therefore deactivates the protection.
If the machine is left without power for long periods in areas where tem-
peratures may fall below >0°C, and you do not want to drain the heating
system, you are advised to add a good quality anti-freeze liquid to the
primary circuit to protect the machine from any risk of freezing. Carefully
follow the manufacturer's instructions with regards not only the percent-
age of anti-freeze liquid to be used for the minimum temperature at which
you want to keep the machine circuit, but also the duration and disposal
of the liquid itself.
For the DHW part, we recommend you drain the circuit.
The boiler components are made of materials resistant to antifreeze liq-
uids containing ethylene glycol.
When the boiler is installed in a place where there is a danger of frost, with
outdoor air temperatures below >0°C, an anti-freeze heater kit - available
on request - must be used to protect the sanitary circuit and condensate
drain (see catalogue price list), which protects the boiler down to -15°C.
b
The assembly of the antifreeze heater kit must only be carried out
by authorized personnel, following the instructions contained in the
packaging of the kit.
MINIMUM CLEARANCES
Access the inside of the boiler for routine maintenance tasks, respecting
the minimum installation clearances.
When positioning the appliance, bear in mind that:
- it must be installed on a wall that can support its weight
- it must not be placed above a cooker or other cooking device;

4.3 Instructions for the condensate discharge
connection
This product is designed to prevent the escape of flue gaseous
through the condensate drainage pipe with which it is equipped; this
is achieved through the use of a special drain-trap located inside the
appliance.
b All the components of the condensate drainage system must
be correctly serviced as per the manufacturer's indications,
and must not be modified in any way.
The condensate drain outlet system downstream from the appliance
must be made in accordance with the relevant legislation and
regulations in force; this is the responsibility of the installer. The system
must be sized and installed so as to ensure the correct evacuation
of the condensate produced by the appliance and/or collected by the
flue gas evacuation systems. All the system components must be
made to the highest standards, using materials able to withstand the
long-term mechanical, thermal and chemical stress created by the
condensate.
Note: if the condensate drain outlet system is exposed to the risk
of freezing temperatures, always ensure a suitable level of pipe
insulation and consider increasing the diameter of the pipe itself.
The pipe must slope sufficiently to prevent the condensate from
stagnating and guarantee it is correctly drained off. There must be an
examinable disconnection between the condensate drain outlet pipe
of the appliance and the condensate drain outlet system.

High voltage connections
The connection to the mains supply must be made via a separation device
with an omnipolar opening of at least 3.5 mm (EN 60335/1 - category
3). The appliance works with alternating current at 230 Volt/50 Hz, and
is in compliance with Standard EN 60335-1. It is obligatory to make the
connection with a safe ground/earth, in compliance with current directives.
b
The installer is responsible for ensuring the appliance is suitably
earthed; the manufacturer will not be liable for any damage result-
ing from an incorrect or absent earth connection.
b
It is also recommended to uphold the phase-neutral connection
(L-N).
b
The ground/earth wire must be a couple of cm longer than the others.
b
To create the seal of the boiler use a clamp and tighten it on the
cable grommet used.
The boiler can operate with a phase-neutral or phase-phase supply. It is
forbidden to use gas and/or water pipes to earth electrical appliances.
Use the power cable supplied to connect the boiler to the mains power
supply. If the power cable has to be replaced, use a HAR H05V2V2-F
cable, 3 x 0.75mm
2
, Ø max external 7 mm.
4.6 Gas connection
The connection of the gas supply must be carried out in compliance with
current installation standards. Before making the connection:
- check that the gas supplied corresponds to that for which the boiler has
been prepared (see nameplate).

b If the front panel is damaged, it must be replaced.
b
The noise-absorbing panels in the front and side walls ensure
the airtight seal of the air supply pipe in relation to the place of
installation.
b
It is therefore ESSENTIAL that components are repositioned cor-
rectly after disassembly in order to guarantee the tightness of
the boiler.

5.2 Initial start-up
On first start-up, in the event of prolonged non-use and in the event of
maintenance work, it is essential to proceed as described in the following
paragraphs before putting the appliance into operation.
At the first start-up, the calibration procedure (GAC) is also recommen-
ded to allow the boiler to reach its optimal performance.
5.2.1 Condensate trap filling
Fill the condensate collection drain-trap, pouring about 1 litre of water
into the boiler combustion analysis outlet, and check that:
- the water leaving the boiler via the discharge tube is running off cor-
rectly
- the seal on the condensate discharge connection line.

When the vent cycle is running all heat requests are inhibited
except for DHW requests when the boiler is not in OFF.
The cycle can also be interrupted by a DHW request, if the boiler is not
OFF.
5.4 Manual calibration procedure (GAC)
The GAC procedure, which is useful to calibrate the gas valve and
combustion control system, is mandatory following: gas conversion - gas
valve replacement - board replacement - fan replacement - cleaning of

If the procedure is not carried out when it is mandatory to do so, it may
lead to a limited operation and the possibility of abnormal combustion

If a fault occurs during the procedure, or if the heat request is interrupted,
the procedure would be prematurely terminated by displaying the fault
status or automatically returning to the main screen. In this case, the
procedure must be repeated.
5.5 Setting the thermoregulation
Thermoregulation is only available with an outdoor temperature sensor
connected and is only active for the HEATING function.
THERMOREGULATION is enabled in the following way:
access the parameter P4 3 .
With 3  or the outdoor temperature sensor disconnected, the boil-
er ZRUNVDWDIL[HGVHWSRLQW.
The temperature value measured by the outdoor temperature sensor is
displayed in the "6.3 INFO menu" at I009.
The thermoregulation algorithm will not use the measured outdoor tem-
perature value directly, but rather a weighted outdoor temperature value,
which takes account of the insulation of the building: in well-insulated
buildings, external temperature variations have less influence on the
room temperature than in less insulated buildings.
This value can be displayed in the INFO menu at I010.
REQUEST FROM OT CHRONOTHERMOSTAT
In this case, the delivery setpoint is calculated by the timed thermostat
on the basis of the outdoor temperature value, and by the difference
between the real ambient temperature and the required ambient tem-
perature.
REQUEST FROM ROOM THERMOSTAT
In this case, the delivery setpoint is calculated by the adjustment board
on the basis of the outdoor temperature value, to obtain an estimated
ambient temperature of 20° (reference ambient temperature).
There are 2 parameters that are used to calculate the delivery setpoint:
slope of the compensation curve (KT) - modifiable by technical per-
sonnel
offset to reference ambient temperature - can be modified by the user.
TYPE OF BUILDING (parameter P433)
It is indicative of the frequency with which the value of the calculated
outdoor temperature for thermoregulation is updated, a low value for this
value will be used for buildings that have little insulation.
REACTIVITY SEXT (parameter P434)
It is an indication of the speed with which variations of the measured
outdoor temperature affect the calculated outdoor temperature value for
thermoregulation, low values indicate high speeds.

described in paragraph "4.10 Filling the heating system and removing air".
b
If the drop in pressure is very frequent, request the intervention of
the Technical Assistance Centre.
Fault E060
The boiler is working normally, but does not guarantee the stability of the
DHW temperature that is, however, supplied at a temperature of around
50°C. Intervention of the Technical Assistance Centre is required.
Fault E091
The boiler has an auto-diagnostic system which, based on the total num-
ber of hours in certain operating conditions, can signal the need to clean
the primary exchanger (alarm code E091).
Once the cleaning operation has been completed, reset to zero the total
hour meter with special kit supplied as an accessory following procedure
indicated below:

- disconnect the boiler from the power supply for at least 10 seconds;
then reconnect to the mains power supply.
Once the replacement is complete, a new "
GAC
” procedure must be car-
ried out (see chap. 5.4).
b
If the gas valve is replaced, also replace the relative sealing
gaskets.
To tighten the gas valve ramp nut, apply a torque equal to 25 Nm, limiting
the rotation of the valve.

5.16 Replacing the interface
System configuration operations must be carried out by professionally
qualified personnel of the Technical Assistance Centre.
If the interface card is replaced, the user may be asked to reset the time
and day of the week values at power on (see "5.2 Initial start-up"); also
check and reset, if necessary, information on hourly heating and DHW
programming (see "8.1 Time band scheduling function (room thermostat)
") and the Feeder Bottle function (see "8.12 FEEDER BOTTLE function");
note that no reprogramming of the configuration parameters is necessary,
the value of which is retrieved from the regulation and control board in
the boiler. Instead
, it may be necessary to reset the DHW and/or heating
setpoint values.
5.17 Board replacement
If the adjustment and control board is replaced, it may be necessary to
reprogram the configuration parameters. After replacing the board, we

sential to the safety, efficiency and duration of the boiler. It allows for the
reduction of consumption, polluting emissions and keeping the product
safe and reliable over time. Before starting maintenance operations:
turn off the fuel and water taps of the heating and domestic hot water
system.
To ensure product characteristics and efficiency remain intact and to
comply with prescriptions of current regulations, it is necessary to ren-
der the appliance to systematic checks at regular intervals. For mainte-
nance, follow the instructions in chapter "1 WARNINGS AND SAFETY".
This normally means the following tasks:
removing any oxidation from the burner
removing any scale from the heat exchangers
check the state of deterioration of the electrodes and, if they have
deteriorated, replace them together with their seals
check and general cleaning of exhaust and intake pipes
checking the external appearance of the boiler
checking the ignition, switch-off and operation of the appliance, in
both DHW mode and heating mode
checking the seal on the couplings and the gas/water/condensate
connection pipes
checking gas consumption at maximum and minimum output
if the DHW pressure is less than 3 bar, empty the boiler's DHW circuit
and check that the heating circuit pressure is maintained
checking the integrity of the insulation of electrical cables, particularly
in the vicinity of the primary heat exchanger
checking the gas failure safety device

b
When servicing the boiler, the use of protective clothing is
recommended in order to avoid personal injury.
b
After maintenance work has been carried out, an analysis of the
combustion products must be carried out to check that they are
functioning properly.
b
If, after any replacement of electronic board, heat exchanger, fan/
mixer and gas valve, or having carried out maintenance on the
ignition and detection electrodes or on the burner, the flue gas
analysis returns out-of-tolerance values, it is necessary to repeat
the "GAC" procedure (see chap. 5.4).
