VENTILATION REQUIREMENTS

The appliance must be installed in compliance with applicable local regulations con-

cerning ventilation and the evacuation of exhaust gases.

Intensive and prolonged use may require extra ventilation, e.g. opening a window,

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 200 cm

(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 com-

pliance 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. 6.3).

If this is not possible, an electric fan may be used, attached to the external wall or the win-

dow; the fan should have a capacity to circulate air at an hourly rate of 3-5 times the total

volume of the kitchen (Fig. 6.4).

The fan can only be installed if the room has suitable vents to allow air to enter, as descri-

bed under the heading “Choosing suitable surroundings”.
