and keep the safety features, performance and
reliability, which distinguish it, unchanged over
time, you must at least execute maintenance
operations on a yearly basis in compliance
with what is stated in the relative point at “an-
nual check and maintenance of the appliance”,
in compliance with national, regional, or local
standards in force.
2.2 VENTILATION OF THE ROOMS.
In the room in which the boiler is installed it
is necessary that at least as much air ows as
that requested for by normal combustion of the
gas and ventilation of the room. e provisions
relative to ventilation, the ue pipes, chimneys
and caps are stated in Par. 1.8, 1.9 and 1.10. If in
doubt regarding correct ventilation, contact an
authorised company.
2.3 GENERAL WARNINGS.
Never expose the wall-mounted boiler to direct
vapours from a cooking surface.
Use of the boiler by unskilled persons or children
is strictly prohibited.
If temporary shutdown of the boiler is required,
proceed as follows:
a) drain the heating system if anti-freeze is not
used;
b) shut-o all electrical, water and gas supplies.
In the case of work or maintenance to structures
near ducting or devices for ue extraction and the
relative accessories, switch o the appliance and
on completion of the operations make sure that
an authorised company veries the eciency of
the ducting or the devices.
Never clean the appliance or connected parts
with easily ammable substances.
Never leave containers or ammable substances
in the same environment as the appliance.
It is prohibited and dangerous to obstruct the air
intake, even partially, for the ventilation of the
room in which the boiler is installed.
Due to the danger, functioning is also prohibited
in the same room as suction devices, chimneys
or similar at the same time as the boiler unless
there are additional openings dimensioned in a
way to satisfy the further necessity for air. For the
dimensioning of these additional openings, refer
to an authorised company. In particular, an open
re must have its own air supply.
On the contrary, the boiler cannot be installed
in the same room.
