2.5 Discharge of combustion products
Discharge of combustion products must be guaranteed by means of
hoods connected to a natural draught flue with certain efficiency, or by
means of forced aspiration. An efficient aspiration system requires
careful planning by a specialist capable of installing it, respecting the
positions and distances prescribed by standards. After installation, the
installer must issue a certificate of conformity.
2.6 Gas connection
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.
Use a soapy solution to check for proper tightness. Never use a free
flame.
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 “3. ADAPTING
TO DIFFERENT TYPES OF GAS”. The gas intake fitting is ½” gas
external threaded (ISO 228-1).
Connection with rigid copper pipe:
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 flexible pipe: 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.
2.7 Connection to LPG
Use a pressure regulator and make the connection to the tank according
to the provisions of standards regulations in force. Make sure that feed
pressure conforms to the levels shown in the table in paragraph “3.2
Burner and nozzle characteristics table”.
