7. CONNECTIONS
The position and dimensions of connections are
given in the installation diagram at the end of this
manual.
CONNECTION TO THE GAS SUPPLY
- Check that the appliance is designed to operate
with the type of gas supply present on site. Check
the information given on the decals on the packing
and appliance.
- Convert the appliance to the local gas type, if
necessary. Follow the instructions at 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.
ELECTRICAL CONNECTIONS
Check if 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
dataplate and plaque near the terminal board.
Install upstream of the equipment in an easily
accessible place, an all-pole disconnecting device
with a contact gap of allowing full disconnection
under the conditions of overvoltage category III.
A flexible rubber cable with insulation
specifications not lower than type H05 RN-F must
be used for connection.
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 appliance with a rigid plastic or metal pipe.
If the power supply cable is damaged, it must be
replaced by the manufacturer or his service centre
or by a person with similar qualifications to
prevent any risk.
THE SYMBOL “ HIGH VOLTAGE” IS
PLACED ON A PANEL THAT GIVES
ACCESS TO A PART WITH HIGH
VOLTAGE.
PROTECTIVE EARTH AND EARTH BONDING
CONNECTIONS
- Connect the appliance to an efficient ground
circuit. Connect the earth conductor to the
terminal with the symbol next to the main
terminal board.
Connect the metal structure of the appliance to
the equipotential node. Connect the conductor to
the terminal with the symbol
on the outside
part of the bottom.
CONNECTION TO THE WATER SUPPLY
- The appliance must be connected to a potable
water supply. 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.
- 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 of ferrous
particles before connecting the filter and the
appliance.
- Seal any unused connectors with a plug.
- Once the appliance has been installed, check for
gas leaks at the connection points.
