Conversion To Another Type Of Gas - Virtus 70/40 FRE8+8 Installation-Emploi-Entretien

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
of the rear panel.
CONNECTION TO THE WATER SUPPLY
- The appliance must be connected to a potable water
supply. The water inlet pressure must be between
placed on the outside
18
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.
CONNECTION TO THE WATER DRAIN
The water drainage system must be made using
materials resistant to temperatures of 100 °C. The
bottom of the appliance 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.
