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efcientventilationincreasingthemechanicalsuctionpowerifthisistted.
CHOOSING SUITABLE SURROUNDINGS
Theroomwherethegasapplianceistobeinstalledmusthaveanaturalowofairsothat
the gas can burn (in compliance with applicable local regulations).
Theowofairmustcomedirectlyfromoneormoreopeningsmadeintheoutsidewalls
with a free area of at least 100 cm
2
(or refer to applicable local regulations).
Theopeningsshouldbeneartheoorandpreferablyonthesideoppositetheexhaustfor
combustion products and must be so made that they cannot be blocked from either the
outside 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(g.8.9).
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(g.8.10).
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”.
