USE OF COOKING HOB
Fig. 2
✓ To light one of the gas burners, hold
a flame (e.g. a match) close to the top part of the burner, push in and turn the relative knob in an anti-clockwise direction, pointing the knob indicator towards the large flame symbol (i.e. max. gas flow).
✓ To reduce the gas flow to minimum,
rotate the knob further anti-clockwise to point the indicator towards the small flame symbol.
✓ The maximum aperture position
permits rapid boiling of liquids, whereas the minimum aperture position allows slower warming of food or maintaining boiling conditions of liquids.
✓ Other intermediate operating
adjustments can be achieved by positioning the indicator between the maximum and minimum aperture positions, and never between the maximum aperture and closed positions.
GAS BURNERS
Gas flow to the burners is adjusted by turning the knobs illustrated in fig. 2 which control the safety valves. Turning the knob so that the indicator line points to the symbols printed on the panel achieves the following functions:
– full circle
● = closed valve
– symbol = maximum
aperture or flow
– symbol = minimum
aperture or flow

Lighting the burners WITH ELECTRIC IGNITION (without safety valve device)
mod. EH 733 WH, EH 733 BK with ignition incorporated in the burner knobs
These models can be identified by the ★ symbol near the flame position symbol (Fig. 3). To light one of the burners, press and turn the corresponding knob to the maximum flow position (large flame) and keep the knob pressed down until the gas is lit.
Turn the gas tap to the position required. Whenever special conditions of the gas
supplied locally make it difficult to light the burner with the knob in the maximum flow position, repeat the operation with the knob in the minimum flow position.
The device shall not be operated for more than 15 seconds. If after 15 seconds the burner has not lit, stop operating the device and open the compartment door and/or wait at least 1 minute before attempting a further ignition of the burner.
Lighting the burners WITH ELECTRIC IGNITION (fitted with safety valve device)
mod. EHS 733 WH, EHS 733 BK model with ignition incorporated in the
burner knobs
These models can be identified by the ★ symbol near the flame position symbol (Fig. 3).In order to light the burner, you must:
1 – Turn the knob in an anti-clockwise
direction up to the maximum aperture, push in and hold the knob (fig. 3); the sparks produced by the electrode situated next to the burner will light;
2 – Wait for about ten seconds after
the gas burner has been lit before letting go of the knob (valve activation delay);
3 – Adjust the gas valve to the desired
position.
If the burner flame should go out for some reason, the safety valve will automatically stop the gas flow. To re-light the burner, return the knob to the closed
● position and repeat the
operations for lighting. If your local gas supply makes it
difficult to light the burner with the knob set to maximum, set the knob to minimum and repeat the operation.

ATTENTION: The cooktop becomes very hot
while in operation. Keep children away.
CHOICE OF THE BURNER
On the control panel, near every knob, there is a diagram that indicates which burner is controlled by that knob. The suitable burner must be chosen according to the diameter and the capacity used. As an indication, the burners and the pots must be used in the following way:
Fig. 4
It is important that the diameter of the pots or pans suitably match the heating potential of the burners in order not to jeopardise the efficiency of the burners, bringing about a waste of gas fuel. A small diameter pot or pan placed on a large burner does not necessarily mean that boiling conditions are reached quicker.
BURNERS POT DIAMETER
Semi-rapid 12 - 24 cm Triple-ring 24 - 28 cm
wok max. 36 cm
NOTE: Only used flat bottomed pans.
Page 8
8
Do not place anything, e.g. flame tamer, asbestos mat, between pan and pan support as serious damage to the appliance may result.
Locate pan centrally over the burner so that it is stable and does not overhang the appliance.
Use only a wok support supplied or recommended by the manufacturer of the appliance.
Do not remove the pan support and enclose the burner with a wok stand as this will concentrate and deflect the heat onto the hotplate.
Do not use large pots or heavy weights which can bend the pan support or deflect the flame onto the hotplate.

INSTALLATION ROOM
The room where the gas appliance is to be installed must have a natural flow of air so that the gas can burn.
The flow of air must come directly from one or more openings made in the out­side walls with a free area of at least 100 cm
2
. If the appliance does not have a no­flame safety device this opening must have an area of at least 200 cm
2
.
The openings should be near the floor and preferably on the side opposite the exhaust for combustion products and must be so made that they cannot be blocked from either the outside or the outside.
When these openings cannot be made the necessary air can come from an adjacent room which is ventilated as required, as long as it is not a bedroom or a dangerous area. In this case the kitchen door must allow the passage of the air.

IMPORTANT: Installation has to be carried out according to the instructions provid­ed by the manufacturer. Incorrect installation might cause harm and damage to people, animals or objects, for which the manufactur­er accepts no responsibility.
DETAILS
✓ Connection to the electric power
supply must be carried out by a qualified technician and following the appropriate safety regulations;
✓ Before carrying out the connection to
the power supply, the voltage rating of the appliance (stamped on the appliance identification plate) must be checked for correspondence to the available mains supply voltage, and the mains electric wiring should be capable of handling the hob’s power rating (also indicated on the identification plate);
✓ The power point must be connected to
a suitable earth wiring, in conformity to current safety regulations.
✓ If the appliance is supplied without
plug, fit a standard plug which is suitable for the power consumed by the appliance.
✓ The colours of the wires in the hob
power cable may not correspond with the colours marked on the terminals of your electrical plug. The plug should in any case be wired as follows:
– connect the green/yellow wire to the
terminal marked with the letter E or the earth symbol or coloured green/yellow;
– connect the blue wire to the
terminal marked with the letter N or coloured black;
– connect the brown wire to the
terminal marked with the letter L or coloured red.
✓ It is possible to connect the appliance
directly to the mains supply by means of a heavy duty switch with 3 mm minimum distance between the contacts.
✓ The power supply cord must not touch
against any hot surfaces and must be placed so that its temperature does not exceed 75°C at any point along its length.
✓ After having installed the appliance,
the power switch or power plug must always be in a accessible position.
N.B. For connections to the mains power supply, never use adapters, reductions or multiple power points as these may overheat and catch fire.
In the event that installation should require modifications to the mains supply wiring system or if the power plug is not suitable for the type of power point available, it is recommended that a qualified technician be called to carry out substitution. The technician will also have to verify that the cross-section of the electric cables on the power point match the appliance’s power rating.
