11 CONNECTIONS

The position and dimensions of connections are given in the
installation diagram at the start of this manual.
CONNECTION TO THE GAS SUPPLY
Check the compatibility of the gas supply. Check the details
given on the decals on the packing and on the appliance. If
necessary, convert the appliance to the type of gas utilized.
Follow the instructions in the next paragraph "Conversion to a
different type of gas".
On top appliances a rear connection is also available. Remove
the plug present and screw it tightly onto the front connector.
• A rapid-action gas shut-off valve must be fitted upstream of
the appliance in an easily accessible position.
• Do not use connection pipes having a diameter smaller than
that of the appliance's gas connector.
• Once the appliance has been installed, check for leaks at the
connection points.
PROTECTIVE EARTH AND EARTH BONDING CONNEC-
TIONS
Connect the appliance to an efficient ground circuit. Connect
the earth conductor to the terminal with the symbol
ted next to the main terminal board.
Connect the metal structure of the appliance to the equipoten-
tial node. Connect the conductor to the terminal with the symbol
on the outside part of the bottom.
• This symbol indicates that the appliance must be included in
an equipotential system connected in compliance with cur-
rent regulations.
CONNECTION TO THE WATER SUPPLY
The appliance must be connected to a potable water supply.
• Install a mechanical filter and a shut-off valve upstream of the
appliance in an easily accessible point.
• Make sure the water circuit is free from ferrous particles befo-
re connecting the filter and the appliance.
• Seal any unused connectors with a plug.
• Once the appliance has been installed, check for leaks at the
connection points.
• Hot water connection: the water temperature must not exceed
60°C.
• The water inlet pressure must be between 150 kPa and 300
kPa. Use a pressure reducer if the inlet pressure is above the
maximum permitted level.
• The appliance is intended to be permanently connected to
the mains water supply and not via disconnectable fittings.
CONNECTION TO THE WATER DRAIN
The water drainage system must be provided using materials
resistant to temperatures of 100 °C. The bottom of the applian-
ce must not be subjected to steam produced by drainage of
hot water. Install a siphoned floor drain with grating below the
water drain cock of Boiling pans and in front of Bratt pans.

12 CONVERSION TO A DIFFERENT TYPE OF GAS

Table T1 specifies, for each country:
• which gas can be used for the appliance.
• the nozzles and settings foreach gas that can be used.For
nozzles, the number indicated in table T1 is also stamped on
the nozzle body.

To convert the appliance to the local gas type, follow the in-
structions given in atable T1 and carry out the steps below:
• Replace the main burner nozzle ( UM ).
• Adjust the main burner's air regulator to distance A.
• Replace the pilot burner nozzle ( UP ).
• Adjust the pilot burner air flow ( if necessary ).
• Replace the gas valve minimum nozzle ( Um ).
• Affix the adhesive tab indicating the new type of gas used.The
nozzles and adhesive tabs are supplied with the appliance.
