9 Not using the boiler for an extended period of time involves
the execution of at least the following operations:
- turn the main appliance switch and the main system switch
to "off"
- close the fuel and water taps of the heating system
- drain the heating and domestic hot water circuits if there is
a risk of freezing.
9 The boiler maintenance must be carried out at least once a
year.
9 This booklet and that of the User are an integral part of the
appliance and therefore should be carefully preserved and
should always accompany the boiler even when it is sold to
another owner or user or when transferred to another system.
In case of loss or damage, please contact your local Technical
Assistance Centre for a new copy.
9 This appliance should not be operated by children younger
than 8 years, people with reduced physical, sensory or men-
tal 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. Chil-
dren must not play with the appliance. It is the user’s respon-
sibility to clean and maintain the appliance. Children should
never clean or maintain it unless they are given supervision.
9 The boiler is constructed so as to protect both the user and
the installer from any accidents.After each intervention on the
product, pay special attention to the electrical connections,
especially the stripped parts of the wires, which must not
protrude from the terminal board in any way.
9 Dispose of all the packaging materials in the suitable
containers at the corresponding collection centres.
9 When disposing of waste, be careful not to harm human
health or employ procedures or methods which may damage
the environment.
At the end of its life, the product should be not be disposed of
as solid urban waste, but rather it should be handed over to a
differentiated waste collection centre.
Remember that the use of products requiring fuels, electricity and
water necessitates the respect of certain basic safety rules
such as:
0 it is forbidden to activate electric devices or appliances such
as switches, household appliances and so on if you notice a
smell of fuel or unburnt fuel;
0 in this case:
- ventilate the room by opening the doors and windows

- promptly call the Technical Assistance Centre or
professionally qualified personnel;
0 it is forbidden to touch the boiler while barefoot or if parts of
your body are wet;
0 it is forbidden to carry out any cleaning operations before
disconnecting the boiler from the electricity supply; to do this,
turn the main system switch to “OFF”;
0 it is forbidden to modify safety and adjustment devices without
the boiler manufacturer's permission and relative instructions;
0 it is forbidden to pull, detach or twist the electric cables that
emerge from the boiler, even if the boiler itself is disconnected
from the mains supply;
0 it is forbidden to plug or reduce the size of any openings used
for airing the installation area;
0 it is forbidden to leave Àammable containers and substances
in the room where the boiler is installed;

6WDUW$TXD&RQGHQV%,6 is a wall-hung condensing boiler, with
premix burner and low emission of pollutants for heating and for the
production of DHW use and has a 45 litre steel storage tank.
This is an electronically controlled boilers with automatic ignition,
ionisation flame check and with proportional control system of the
gas and air flows, both in heating and DHW.
It uses an aluminium alloy boiler body, has a sealed combustion
chamber and, based on the gas discharge accessory used, is
classified in categories B23P, B53P, C13-C13x, C33-C33x, C43-
C43x, C53-C53x, C83-C83xC93C93x. The switching of the heating
and DHW modes is performed via a three-way electric valve which
set on DHW when in the rest position. To guarantee the correct
water output in the exchanger, the boiler is equipped with an
automatic by-pass.
The 6WDUW$TXD&RQGHQV%,6 boiler is also equipped with:
- Range Rated - this means the boiler is equipped with a device
that adapts it to the heat requirements of the system, so the
boiler output can be adjusted according to the energy needs of
the building.
- Circulator anti-blocking.
- First-level antifreeze (suitable for indoor installations).
- 8 litre expansion tank.
- 2 litre DHW expansion tank.
- Digital display indicating the operating temperature and alarm
codes.
- Pre-mix low emissions burner.
- Continuous electronic flame modulation for domestic hot water
and heating.

- Premix combustion system which ensures a constant air-gas
ratio.
- Anti-legionella: Legionella is a disease that can be contracted
by inhaling small droplets of water (aerosols) which contain the
Legionella bacteria (bacteria occurs naturally in lakes and rivers
all over the world). The decimation of the bacterium is obtained
by taking the stored water to a temperature over 50/55° C.
It is therefore recommended to position the DHW temperature
selection knob to maximum at least every 2/3 days, taking the
temperature of the stored water to 60° C, and maintaining this
temperature for a minimum time of 5 minutes.
- Ambient thermostat or programmable timer, remote control or
local valve prearrangement.
- Provision for external probe connection that enables the climate
control function.
- Prepared for limit thermostat on reduced temperature systems.
- Self-diagnostics for signalling the cleaning of the primary circuit
heat exchanger.

9 The boiler must not be put in service, even temporarily, with
non-operating or tampered safety devices.
9 The safety devices must be replaced by the Technical

components.
After carrying out the repair, perform an ignition test.

The residual discharge head for the heating system in terms of flow
rate is outlined in the graph (fig. 1-2).
The heating system pipes must be dimensioned bearing in mind
the residual discharge head available.
Note that the boiler is working properly if the heat exchanger for
heating has sufficient water circulation.
For this reason, the boiler is fitted with an automatic by-pass that
sets the correct flow rate for the water in the heat exchanger for
heating in any system condition.
The boilers are equipped with an anti-blocking system which starts
up an operation cycle after every 24 hours of stop, with the mode
selector in any position.
9 The "anti-locking" function is only activated when the boiler is
electrically powered.
