Panels must be cleaned with ordinary soap and water only.
BURNER CLEANING
The fl ame side of the burner is made with an innovative material of the
latest generation.
- Be especially careful during the dismantling, handling and installation
of the burner and the components next to it (e.g.. electrodes, insulation
panels, etc.)
- Avoid direct contact with any cleaning device (e.g. brushes, vacuum
cleaners, blowers, etc.).
In general, the burner does not require maintenance, but particular cases
may occur where cleaning is necessary (e.g.. distribution network of gas
containing solid particles and in the absence of a fi lter on the line, suction
air containing excessively adhesive particulates, etc.).
For this reason, perform a visual control of the burner in order to ensure the
proper functioning of the product:
- remove the front cover of the air box
- unscrew the fastening nut of the gas train to the valve, remove the gas
train spring clip to the mixer and turn the gas train outwards
- remove the silencer from the mixer
- disconnect the connectors of the wiring from the fan and the connecting
cables of the electrodes
- unscrew the fi xing screws and remove the exchanger-fan cover assembly
from its seat
- unscrew the fi xing screws and remove the burner from its seat checking
it condition.
If necessary, clean the burner with compressed air, blowing
from the metal side of the burner.
It is possible that with ageing, the fi bres constituting the fl ame
side of the burner can tone the colour.
- Reassemble everything in reverse order
If necessary, proceed with the replacement of the sealing
gaskets.
The manufacturer declines all responsibility for any damage caused from
the failure to observe that stated above.

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 modifi ed,
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. If there is a risk of frost,
drain the boiler.
From time to time check that the operating pressure of the hydraulic
system does not go below 1 bar.
In case of failure and/or malfunctioning, deactivate the appliance, and
do not try to repair or operate directly on it.
Appliance maintenance must be carried out at least once a year:
scheduling it with the Technical Assistance Service will avoid wasting
time and money.
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 strict observation of 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 when barefoot.
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 use 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 central gas tap.
Do not place anything in the boiler.
Do not perform any cleaning operation if the appliance is not
disconnected from the mains power supply.
Do not cover or reduce ventilation opening of the room where the
generator is installed.
Do not leave containers and infl ammable 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
qualifi ed personnel.
Do not carry out operations on sealed elements.
For better use, remember that:
- periodic external cleaning with soapy water not only improves its appear-
ance but also preserves panelling from corrosion, extending its life cycle;
- if the wall-mounted boiler is enclosed in a hanging unit, leave at least 5
cm for ventilation and maintenance;
- installation of a room thermostat will greatly improve comfort, a more ra-
tional use of the heat and energy saving; the boiler can also be connected
to a programmable timer in order to control the switching on and off of the
appliance during the day or week.
