Instructions for the installer

4. Gas connection

If the appliance is installed on an oven, the gas pipe must not be passed along the

back of the oven, as this may cause overheating.

Connection to the gas mains may be made with a rigid copper pipe or with a flexible

pipe and conforming to the provisions defined by standard regulations in force.

On models P705 and P64, for easier connection the union A on the back of the

appliance can be adjusted sideways. For this purpose, loosen hexagon nut B, turn

fitting A to the desired position, and retighten hexagon nut B (tightness is ensured by a

biconical brass ring). Use a soapy solution to check for proper tightness. Never use a

free flame.

On model P106 the connection to the pipe must by made using a 90° union. The union

H cannot be turned.

The hob has been inspected for G20 (2H) natural gas at a pressure of 20 mbar. For

use with other types of gases, see Section “5. Adapting to different types of gas ”. The

gas intake fitting is ½” gas external threaded (ISO 228-1).

Connection with rigid copper pipe (P64/P705): the

connection to the gas mains must not provoke stress of

any kind on the hob. Connection may be made by using

biconical adapter D with insertion of gasket C (supplied).

Connection with copper pipe and 90° union (P106):

the connection to the gas mains must not provoke stress

of any kind on the hob. The connection must be made

using a 90° F union, fitting the seal C provided in all

cases. Screw the union F onto the gas train H of the hob

using 2 spanners in opposite directions.

Connection with flexible pipe (All models): use only

flexible pipes conforming to standard regulations in force,

inserting gasket C (supplied) between fitting A and

flexible pipe E.

The flexible pipe has to be installed so that pipe length does not exceed 1.5 meters of

maximum extension. Make sure that the pipes do not touch any moving parts or

become damaged.
