Ventilation Requirements - BORETTI CFBG901AN Prescriptions De Montage Et Mode D'emploi

VENTILATION REQUIREMENTS

The appliance must be installed in compliance with applicable local regulations
concerning ventilation and the evacuation of exhaust gases.
Intensive and prolonged use may require extra ventilation, e.g. opening a window,
or more efficient ventilation increasing the mechanical suction power if this is fitted.
CHOOSING SUITABLE SURROUNDINGS
The room where the gas appliance is to be installed must have a natural flow of air so that
the gas can burn (in compliance with applicable local regulations).
The flow of air must come directly from one or more openings made in the outside walls
with a free area of at least 100 cm
The openings should be near the floor and preferably on the side opposite the exhaust for
combustion products and must be made so that they cannot be blocked from either the
inside or the outside.
When these openings cannot be made, the necessary air can come from an adjacent
room which is ventilated as required, as long as it is not a bed room or a danger area (in
compliance with applicable local regulations).
In this case, the kitchen door must allow the passage of the air.
DISCHARGING PRODUCTS OF COMBUSTION
Extractor hoods connected directly to the outside must be provided, to allow the products
of combustion of the gas appliance to be discharged (fig. 7.9).
If this is not possible, an electric fan may be used, attached to the external wall or the
window; the fan should have a capacity to circulate air at an hourly rate of 3-5 times the
total volume of the kitchen (fig. 7.10).
The fan can only be installed if the room has suitable vents to allow air to enter, as described
under the heading "Choosing suitable surroundings".
