3.9 Ventilation in rooms with 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.
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
2
.
For the essential air intake into the room, it is necessary to prepare a similar opening of at least
100 cm
2 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 than
2 m
3
/h
per kW
of power (see total power in kW shown on the appliance plate).
In all other cases, i.e. when other gas appliances are present in the same room, or, if it is not
possible to have natural direct ventilation, it is necessary to create natural, indirect ventilation or
forced ventilation:
for this type of operation, it is necessary to contact a qualified technician
for installing and creating the ventilation system in strict compliance with the guidelines set
out in current standards.
The openings should be positioned so as not to allow the formation of any unpleasant air current
for the occupants. Furthermore, it is forbidden to use flues already used by other appliances to
expel products of combustion.
