Hotpoint-Ariston 641 DD /HA(CH) [7/28] Electrical connection

• 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 at surface with an opening of at least 45 x 560

mm (see diagrams).

560 mm.

45 mm.

! 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 or to a gas

cylinder 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. If this is not the case, follow the instructions indicated in the

paragraph “Adapting to different types of gas.”

When using liquid gas from a cylinder, install a pressure regulator which

complies with current national regulations.

! Check that the pressure of the gas supply is consistent with the values

indicated in Table 1 (“Burner and nozzle specications”). This will ensure the

safe operation and longevity of your appliance while maintaining efcient

energy consumption.

Attention! Before connection remove a transport plug from the connecting

hole of the cooker gas pipeline.

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 tting on the appliance supply ramp

and this is tted with a seal in order to prevent leaks. The seal must always

be replaced after rotating the pipe tting (seal provided with appliance). The

gas supply pipe tting is a threaded 1/2 gas cylindrical male attachment.

Connecting a flexible jointless stainless steel pipe to a threaded

attachment

The gas supply pipe tting 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 exible 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 ttings for leaks

using a soapy solution. Never use a ame.

Adapting to different types of gas

To adapt the hob to a different type of gas other than default type (indicated

on the rating plate at the base of the hob or on the packaging), the burner

nozzles should be replaced as follows:

1. Remove the hob grids and slide the burners off their seats.

2. Unscrew the nozzles using a 7 mm socket spanner, and replace them

with nozzles for the new type of gas (see table 1 “Burner and nozzle

characteristics”).

In the case of the Mini WOK burner, use a

spanner with a 7 mm opening to unscrew the

nozzle (see gure).

3. Reassemble the parts following the above procedure in the reverse order.

4. Once this procedure is nished, replace the old rating sticker with one

indicating the new type of gas used. Sticker are available from any of our

Service Centres.

• Adjusting the burners’ primary air

Does not require adjusting.
