3.4 Ventilation in rooms gas appliances
this appliance is not connected to an exhaust device for products of
combustion. It must therefore be installed and connected in compliance with
current installation standards. Pay particular attention to standards applied to
room aeration.
This appliance can only be installed in ventilated rooms, according to current
standards, so as to allow, with openings onto external walls or appropriate
ducts, for correct natural or forced ventilation that permanently and sufficiently
ensures both the air intake necessary for correct combustion and the expelling
of vitiated air. It is recommended that the appliance have a rangehood fitted
directly above or ceiling fan in close proximity to the appliance.
Note:
Using a gas cooking appliance produces heat and humidity in the room
where it is installed. Ensure good room ventilation: keep natural ventilation
grilles open or install a mechanical ventilation device (ducted extraction
hood). Intensive and prolonged appliance use may require supplementary
ventilation, for example, opening a window, more effective ventilation, or
increasing the extraction hood power, if installed.
If this is the only gas appliance in the room, it is necessary to install a hood so
as to expel vitiated air naturally and directly, with a rectilinear vertical duct at
least twice as long as its diameter and having a minimum section of at least
100 cm .

For the essential air intake into the room, it is necessary to prepare a similar
opening of at least 100 cm2 that communicates directly outside, situated
close to floor level so as not to be obstructed from either inside or outside and
so as not to disturb the combustion of the burners and the correct expelling
of vitiated air and with a height difference from the exit opening of at least
180 cm.
Remember that the quantity of air necessary for combustion must not be lower
