required for regular combustion of the gas and for

ventilating the same room. Air must be taken in

naturally through permanent apertures made in the

outside walls of the room or through single or

branching collective ventilation ducts in compliance

with the standards in force. The air must be taken

directly from the outside, from an area far from

sources of pollution. The ventilation aperture must

have the following characteristics (fig.11A):

• total free cross section of passage of at least 6

cm² for every kW of rated heating capacity of the

appliance, with a minimum of 100 cm² (the

heating capacity is indicated on the rating plate);

• it must be made in such a way that the aperture

cannot be obstructed both on the inside and

outside of the wall;

• it must be protected, e.g. with grills, wire mesh,

etc. in such a way that the above-mentioned free

section is not reduced;

• it must be situated as near to floor level as

possible.

The air inflow may also be obtained from an

adjoining room, provided the latter is not a bedroom

or a room where there is a risk of fire, such as

warehouses, garages, fuel stores, etc. and is

ventilated in compliance with the standards in force.

Air from the adjoining room to the one to be

ventilated may be made to pass freely through

permanent apertures with a cross section at least

equal to that indicated above. These apertures may

also be obtained by increasing the gap between the

door and the floor (fig.11B). If an electric fan is used

for extracting the combustion products, the

ventilation aperture must be increased in relation to

its maximum performance. The electric fan should

have a sufficient capacity to guarantee an hourly

exchange of air equal to 3 ÷ 5 times the volume of

the kitchen. Prolonged, intensive use of the

appliance may require extra ventilation, e.g. an open

window or a more efficient ventilation system by

increasing the extraction power of the electric fan if

installed. Liquid petroleum gas descends towards

the floor as it is heavier than air. Apertures in the

outside walls in rooms containing LPG cylinders

should therefore be at floor level, in order to allow

any gas from leaks to be expelled. Do not store

LPG cylinders (even when empty) in basements/

rooms below ground level; it is advisable to keep

only the cylinder in use in the room and connected

far from heat sources which could raise its

temperature to above 50°C.

Gas supply

• Check that the appliance is set for the type of gas

available and then connect it to the mains gas

piping or the gas cylinder in compliance with the

applicable norms in force.

• This appliance is designed and set to work with

the gas indicated on the label situated on the

actual hob. If the gas supply is different from the

type for which the appliance has been set,

replace the corresponding nozzles (provided),

following the instructions given in the paragraph

"Adaptation to different types of gas".

• For trouble-free operation, suitable use of energy

and a longer life cycle for the appliance, make

sure that the supply pressure complies with the

values indicated in table 1 "Burner and nozzle

specifications", otherwise install a special

pressure regulator on the supply pipe in

compliance with current standards and

regulations.

• Connect in such a way that the appliance is

subjected to no strain whatsoever.

Either a rigid metal pipe with fittings (fig. 12-D) in

compliance with norms must be used for connecting

to the nipple union (threaded - cylindrical ½"G fitting

"F") situated at the rear of the appliance (fig. 12), or

a flexible steel pipe with a continuous wall and

fittings (fig. 12-C) in compliance with norms, which

must not exceed 2000 mm in length. Check that the

connecting pipe cannot come into contact with

moving parts which could damage or crush it. For

installation with a flexible rubber pipe, apply the

special hose support for

liquid gasliquid gas

natural gas (fig. 12-B). The gasket "G" (provided)

must be utilised in every type of connection. The two

ends of the pipe must be fastened with the purpose

designed pipe collars "E", in compliance with the

norms. The flexible pipe should comply with the

norms, and be specific for the type of gas used. In

addition:

• it should be as short as possible, with a maximum

length of 1.5 metres;

• it should not be bent or kinked;

• it should not be in contact with the rear panel of

the appliance or in any case with parts which may
