• Position the "B21" type appliance below an extractor hood.
8.3 APPLIANCE TYPE "B11"
• Fit the "B11" type appliance with a suitable flue, available
from the appliance manufacturer. Follow the assembly in
-
structions provided with the flue.
• 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
, if used, is:
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
loca-
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
9.4 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.
9.5 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.
