• Connect the flue to a 150/155 mm diameter hose, heat resi-
stant to 300°C.
• Vent to the outside or into an efficient flue. The hose length
must not exceed 3 metres.

9 CONNECTIONS

The position and dimensions of connections are given in the
installation diagram at the start of this manual.
9.1 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.Con-
vert the appliance to the local gas type, if necessary. 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 gas leaks at
the connection points.

9.2 ELECTRICAL CONNECTIONS

Check that the appliance is designed to operate at the voltage
and frequency of the power supply present on site. Check the
details given on the appliance data plate.
The meaning of symbol
WARNING DANGEROUS VOLTAGE.
• Install an adequately rated omnipolar circuit-breaker upline
of the appliance in an easily accessible point, in compliance
with installation regulations; the circuit breaker must guaran-
tee immediate omnipolar disconnection from the mains, with
a minimum contact opening that allows complete disconnec-
tion in overvoltage category III conditions. The maximum per-
mitted current dispersion is 1mA/kW.
• For electrical connection, use a rubber-sheathed flexible ca-
ble which is oil resistant, type H05RN-F or H07RN-F, for ca-
ble size consult the technical data table.
• Connect the power supply cable to the terminal board as
shown in the wiring diagram supplied with the appliance.
• Secure the power supply cable with the cable clamp.
• Protect the power supply cable on the outside of the applian-
ce with a rigid plastic or metal pipe.
• If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons
in order to avoid a hazard.
9.3 PROTECTIVE EARTH AND EARTH BONDING CON-
NECTIONS
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

10 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.
10.1 REPLACING THE MAIN BURNER NOZZLE AND ADJU-
STING THE PRIMARY AIR FLOW.
• Slacken screw V.
• Remove nozzle UM (fitted to air regulator Z) and replace it
with the one indicated in table T1.
• Retighten nozzle UM (fitted to air regulator Z).
• Adjust air regulator Z to distance A as shown in table T1.
• Retighten screw V fully.
• Re-assemble all parts. For assembly, proceed in reverse or-
der.

10.2 REPLACING THE PILOT BURNER NOZZLE

• Undo connector R.
• Remove nozzle UP and replace it with the one indicated in
table T1.
• Retighten connector R.
• Re-assemble all parts. For assembly, proceed in reverse or-
der.
