Instructions for use

Once the hob has been installed, it is important to remove any protective
materials, which were put on in the factory.

The hob control knobs

The symbols on the control knobs mean the following:

no gas flow
maximum gas flow
minimum gas flow

All operating positions must be set between the maximum and minimum flow settings,
and never between the maximum setting and the closed position.

Lighting the burners

To obtain a flame more easily, light the burner before placing a cooking utensil
on the pan stand.

To light a burner, proceed as follows: for version with lighting integrated in the
control knob, push the knob of the burner fully down and turn it anticlockwise
to the "maximum flow" setting symbol, or press the button if the appliance has
individual lighting.

After lighting the flame, keep the knob pressed for about 10 seconds; this time
is necessary to heat up the "thermocouple" (Fig. 1-C) and activate the safety
valve, which would otherwise cut off the gas flow.

Then check that the flame is even and turn the control knob to adjust the
flame as required.

In the instance of a power cut, place a flame near the burner and proceed as already
described.

If the flame does not light after a few attempts, check that the "burner cap" and "flame
cap" are correctly positioned.

To turn off the flame, turn the control knob clockwise to the symbol.
Before removing pans from the burners, always lower or turn off the flame.

Correct use of the hob

For lower gas consumption and
to ensure maximum burner effi­ciency, you should only use pots
and pans with a flat bottom fitting
the size of the burner used (see
table). Also, as soon as a liquid
comes to the boil take care to turn
the flame down to a level that will
just keep it boiling.

When cooking with fats or oils, do not leave the pan unattenced because
these substances may catch fire if brought to high temperatures.

If the control knobs become difficult to turn, please contact your local
Service Force Centre.

Medium (semi-rapid) 120 mm. 200 mm.
Small (Auxiliary) 80 mm. 160 mm.
Triple Flame 220 mm. 260 mm.

Cleaning and maintenance

Before any maintenance or cleaning can be carried out, you must DISCONNECT
the hob from the electricity supply.

The hob is best cleaned whilst it is still warm, as spillage can be removed more easily
than if it is left to cool.

General cleaning

Wash enamelled parts with lukewarm water and detergent; do not use abrasive
products which might damage them.
Wash the flame caps and burner caps often with boiling water and detergent, taking
care to remove all deposits.
The hob pan stands can also be washed in a dishwasher.
For stubborn dirt, use ordinary non-abrasive detergents or specific commercial products.
We strongly advise you not to use scouring pads, steel wool or acids for cleaning.

Hob

Clean the hob regularly with a soft cloth wet with lukewarm water and a little liquid
detergent. Do not use the following products:

- household detergents or bleaches;

- soaped scouring pads not suitable for non-stick utensils;

- steel wool scouring pads;

- stain removers for baths or sinks.
Should the hob top become heavily soiled, it is recommended that a cleaning product
such as Hob Brite or Bar Keepers Friend is used.

Ignition plug

Automatic burner ignition is provided (when in­stalled) by a ceramic "plug" and a metal electrode
(B in fig. 1). Periodically clean these parts of the
hob thoroughly. In addition, to avoid ignition
difficulties, check that the cavities in the burner
are not obstructed.
To remove deposits from the burner cavities,
remove the cap and separate the two parts (see
diagram on the right). After cleaning, put the two
parts back together and return them correctly to
their position. After washing, replace the hob pan
stands, checking that they are correctly positioned.

Electrical connection

WARNING: THIS APPLIANCE MUST BE EARTHED.
All external wiring must comply with the IEE
Regulations for the Electrical Equipment of Buildings.
The electrical supply can be by either a plug and
socket or a permanently wired connection via a
double - pole switch. Should the plug (where supplied)
not fit the socket in your home, it should be removed
and replaced with a suitable plug.
Note: If a moulded plug is fitted which is not suitable,
it must be cut off and disposed of properly. To avoid
the risk of electrocution, the moulded plug must not
be left where children might find it and plug it into a
supply socket. It must not be used for any other
appliance. Three pin plugs to BS1363 with a capacity
of not less than 13A must be used and fitted with a
3 amp fuse ‘ASTA’ approved to BS 1362.
With moulded plugs, after replacing the fuse the
cover must be refitted. If the cover is lost, the plug
must not be used until a replacement cover has been
obtained from your supplier. The colour of the correct
fuse cover is that of the coloured insert in the base
of the fuse recess, or stated elsewhere on the plug.
Always state this colour when ordering a replacement
fuse cover. If you wish to make a direct connection
to the mains, an omnipolar switch with a gap between
the contacts of at least 3 mm, of suitable rating for
the load and complying with the regulations in force,
must be installed between the appliance and the
mains.The switch must not break a contact in the
yellow/green earth wire.

Replacing the power supply lead

If the lead has to be replaced, only HO5RR-F or HO5RN-F type cables suitable for
the load and the operating temperature must be used.In addition, the yellow/green
earth wire must be about 2 cm longer than the live and neutral wires.
In all cases, the power supply lead must be positioned so that it does not reach a
temperature 50°C above the room temperature in any point.
One example of an ideal route is shown in the illustration.The cable is guided by
means of band clamps fixed to the side of the cabinet, in order to avoid any contact
with the appliance underneath the hob.

Adapting to the different types of gas

Changing the nozzles

1) Remove the pan stands

2) Remove the burner caps and flame caps from the
burners.

3) Use a size 7 socket wrench to unscrew and remove
the nozzles, replacing them with those corresponding
to the type of gas to be used (see table).

4) Reassemble the parts, reversing the operations
described above.

5) Then replace the setting data plate (close to the
mains gas connection) with the one for the new type
of gas (it is in the bag of nozzles provided).

If the pressure of the gas used is different from that specified (or variable), a suitable
piped gas pressure regulator complying with the standard must be installed on the
supply pipeline.

Setting the minimum level

1) Light the burner as already described.

2) Turn the tap to the minimum flame position.

3) Remove the control knobs.

4) Use a thin straight screwdriver to turn the by-pass pin located
next to the tap rod (see fig. A).If you are converting from natural
gas to LPG, turn the by-pass pin fully clockwise.

The result should be a small, homogeneous flame which is
uniform around the entire burner ring.

5) Finally, check that the burner does not go out when the tap is
turned quickly from the maximum to the minimum position.
