Gas Connection; Adapting To Different Types Of Gas - Ariston CP 057 GT S Operating Instructions Manual

! The manufacturer declines any liability should these safety measures
not be observed.
Replacing the cable
Use a rubber cable of the type H05VV-F with a cross section of 3 x 1.5 mm².
The yellow-green earth wire must be 2 ÷ 3 cm longer than the other wires.

Gas connection

Connection to the gas network or to the gas cylinder may be carried out using
a flexible rubber or steel hose, in accordance with current national legislation
and after making sure that the appliance is suited to the type of gas with which
it will be supplied (see the rating sticker on the cover: if this is not the case
see below). When using liquid gas from a cylinder, install a pressure regulator
which complies with current national regulations.
! Make sure that the gas supply pressure is consistent with the values indicated
in the Table of burner and nozzle specifications (see below). This will ensure
the safe operation and durability of your appliance while maintaining efficient
energy consumption.
Gas connection using a flexible rubber hose
Make sure that the hose complies with current national legislation. The
internal diameter of the hose must measure: 8 mm for a liquid gas supply;13
mm for a methane gas supply.
Once the connection has been performed, make sure that the hose:
• Does not come into contact with any parts which reach temperatures of
over 50°C.
• Is not subject to any pulling or twisting forces and that it is not kinked or
bent.
• Does not come into contact with blades, sharp corners or moving parts
and that it is not compressed.
• Is easy to inspect along its whole length so that its condition may be
checked.
• Is shorter than 1500 mm.
• Fits firmly into place at both ends, where it will be fixed using clamps which
comply with current regulations.
! If one or more of these conditions is not fulfilled or if the cooker must be
installed according to the conditions listed for class 2 - subclass 1 appliances
(installed between two cupboards), the flexible steel hose must be used
instead (see below).
Connecting a flexible jointless stainless steel pipe to a threaded
attachment
Make sure that the hose and gaskets comply with current national legislation.
To begin using the hose, remove the hose holder on the appliance (the gas
supply inlet on the appliance is a cylindrical threaded 1/2 gas male attachment).
! Perform the connection in such a way that the hose length does not exceed
a maximum of 2 metres, making sure that the hose is not compressed and
does not come into contact with moving parts.
Checking the connection for leaks
When the installation process is complete, check the hose fittings for leaks
using a soapy solution. Never use a flame.

Adapting to different types of gas

It is possible to adapt the appliance to a type of gas other than the default
type (this is indicated on the rating label on the cover).
Adapting the hob
Replacing the nozzles for the hob burners:
1. Remove the hob grids and slide the burners
off their seats.
2. Unscrew the nozzles using a 7 mm socket
spanner (see figure), and replace them with
nozzles suited to the new type of gas (see
Burner and nozzle specifications table).
3. Replace all the components by following
the above instructions in reverse.
Replacing the nozzles on separate "double flame " burners
1. remove the grids and slide the burners from their housings. The burner
consists of 2 separate parts (see figure);
2. unscrew the burers with a 7 mm wrench spanner. The internal burner
has a nozzle, the external burner has two (of the same size). Replace
the nozzle with models suited to the new type of gas (see table 1).
3. replace all the components by repeating the steps in reverse order.
Adjusting the hob burners' minimum setting:
1. Turn the tap to the minimum position.
2. Remove the knob and adjust the regulatory screw, which is positioned
inside or next to the tap pin, until the flame is small but steady.
! If the appliance is connected to a liquid gas supply, the regulatory screw
must be fastened as tightly as possible.
3. While the burner is alight, quickly change the position of the knob from
minimum to maximum and vice versa several times, checking that the flame
is not extinguished.
! The hob burners do not require primary air adjustment.
! After adjusting the appliance so it may be used with a different type of
gas, replace the old rating label with a new one which corresponds to
the new type of gas (these labels are available from Authorised Technical
Assistance Centres).
! Should the gas pressure used be different (or vary slightly) from the
recommended pressure, a suitable pressure regulator must be fitted to the
inlet hose in accordance with current national regulations relating to "regulators
for channelled gas".
