Gas Connection; Electrical Connection - Ariston PK 644 D GH E X Operating Instruction

• Where the hob is not installed over a built-in oven, a wooden panel must
be installed as insulation. This must be placed at a minimum distance of
20 mm from the lower part of the hob.
Ventilation
To ensure adequate ventilation, the back panel of the cabinet must be
removed. It is advisable to install the oven so that it rests on two strips of
wood, or on a completely flat surface with an opening of at least 45 x 560
mm (see diagrams).
! The hob can only be installed above built-in ovens with a cooling ventilation
system.

Electrical connection

Hobs equipped with a three-pole power supply cable are designed to operate
with alternating current at the voltage and frequency indicated on the data
plate (this is located on the lower part of the appliance). The earth wire in the
cable has a green and yellow cover. If the appliance is to be installed above
a built-in electric oven, the electrical connection of the hob and the oven must
be carried out separately, both for electrical safety purposes and to make
extracting the oven easier.
Connecting the supply cable to the mains
Install a standardised plug corresponding to the load indicated on the data
plate. The appliance must be directly connected to the mains using an
omnipolar circuit-breaker with a minimum contact opening of 3 mm installed
between the appliance and the mains. The circuit-breaker must be suitable for
the charge indicated and must comply with current electrical regulations (the
earthing wire must not be interrupted by the circuit-breaker). The supply cable
must not come into contact with surfaces with temperatures higher than 50°C.
! The installer must ensure that the correct electrical connection has been
made and that it is compliant with safety regulations.
Before connecting to the power supply, make sure that:
• The appliance is earthed and the plug is compliant with the law.
• The socket can withstand the maximum power of the appliance, which is
indicated on the data plate.
• The voltage is in the range between the values indicated on the data plate.
• The socket is compatible with the plug of the appliance. If the socket is
incompatible with the plug, ask an authorised technician to replace it. Do
not use extension cords or multiple sockets.
! Once the appliance has been installed, the power supply cable and the
electrical socket must be easily accessible.
! The cable must not be bent or compressed.
! The cable must be checked regularly and replaced by authorised technicians
only (see Assistance).
! The manufacturer declines any liability should these safety measures not
be observed.

Gas connection

The appliance should be connected to the main gas supply in compliance
with current national regulations. Before carrying out the connection, make
sure the cooker is compatible with the gas supply you wish to use: G20-
20mbar (Natural Gas).
! Check that the pressure of the gas supply is consistent with the values
indicated in Table 1 ("Burner and nozzle specifications"). This will ensure the
safe operation and longevity of your appliance while maintaining efficient
energy consumption.
Connection with a rigid pipe (copper or steel)
! Connection to the gas system must be carried out in such a way as not to
place any strain of any kind on the appliance.
There is an adjustable L-shaped pipe fitting on the appliance supply ramp
and this is fitted with a seal in order to prevent leaks. The seal must always
be replaced after rotating the pipe fitting (seal provided with appliance). The
gas supply pipe fitting is a threaded 1/2 gas cylindrical male attachment.
Connecting a flexible jointless stainless steel pipe to a threaded
attachment
The gas supply pipe fitting is a threaded 1/2 gas cylindrical male attachment.
These pipes must be installed so that they are never longer than 2000 mm
when fully extended. Once connection has been carried out, make sure that
the flexible metal pipe does not touch any moving parts and is not compressed.
! Only use pipes and seals that comply with current national regulations.
Checking the tightness of the connection
! When the installation process is complete, check the pipe fittings for leaks
using a soapy solution. Never use a flame.
! Should the gas pressure used be different (or vary slightly) from the
recommended pressure, a suitable pressure regulator must be fitted to the
inlet pipe (in order to comply with current national regulations).
