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.

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.

GENERAL

Cleaning and maintenance should be

carried out with the appliance cold

especially when cleaning the

enamelled parts.

Avoid leaving alkaline or acid

substances (lemon juice, vinegar etc.)

on the surfaces.

Avoid using acid or chlorine-based

cleaning products.

ENAMELLED PARTS

All of the enamelled parts must be

washed only with a sponge and soapy

water or with non-abrasive products.

GAS TAPS

Periodic lubrication of the gas taps

must be carried out by specialist

personnel only.

In the event of operating faults in the

gas taps, call the Service Department.

BURNERS AND GRIDS

These parts can be removed and

cleaned with appropriate products.

After cleaning, the burners and their

flame distributors must be well dried

and correctly replaced.

It is very important to check that the

burner flame distributor F and the cap

C has been correctly positioned (see

side figure) - failure to do so can

cause serious problems.

Check that the electrode S is always

clean to ensure trouble-free sparking.

Check that the probe T is always

clean to ensure correct operation of

the safety valves (mod. EHS 733 WH,

EHS 733 BK with safety valve device).

Both the probe and ignition plug must

be very carefully cleaned.

INSTALLATION IN KITCHEN CABINET

WITH DOOR (fig. 13)

The fixture has to be made according

to specific requirements in order to

prevent the gas burners from going out,

even when the flame is turned down to

minimum, due to pressure changes

while opening or closing the cupboard

doors.

It is recommended that a 30 mm

clearance be left between the cooker

top and the fixture surface (fig. 13).

SETTLING THE HOB FOR

INSTALLATION

Every cooker top is provided with a set

of tabs for fitting to the unit with

thickness from 3 to 4 cm and a seal

with adhesive on one side.

– Remove burners and grids.

– Turn the cooker top over and rest

the glass side on a cloth.

– Apply the self-adhesive seal “G” as

illustrated in fig. 14.

– Slot the cooker top into the unit and

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 out-

side walls with a free area of at least 100

cm2.

If the appliance does not have a no-

flame safety device this opening must

have an area of at least 200 cm2.

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.

DISCHARGING PRODUCTS OF

COMBUSTION

Extractor hoods connected directly to

the outside must be provided, to allow

the products of combustion of the gas

appliance to be discharged (fig. 16).

If this is not possible, an electric fan

may be used, attached to the external

wall or the window; the fan should

have a capacity to circulate air at an

hourly rate of 3-5 times the total

volume of the kitchen (fig. 17).

The fan can only be installed if the

room has suitable vents to allow air to

enter, as described under the heading

“Installation room”.

GAS SECTION

TYPES OF GASES

The gases normally used may be

grouped, in view of their features, in

three families:

- L.P.G. (in cylinders) G30

- NATURAL GAS (methane) G20

- CITY GAS G110

INSTALLATION

The appliance is predisposed and

adjusted to operate with the gas indicat-

ed on the specifications plate applied

onto the appliance.

If the appliance must be operated with

a gas different than that indicated on the

plate, it is necessary to execute the fol-

lowing operations:

– gas connection

– replacement of the injectors

– regulating of the minimum

GAS CONNECTION

The connection must be executed by

qualified technician according to the rel-

evant standard.

The fitting (fig. 18) is made up of:

✓1 elbow fitting “A”

✓1 adapter “B” for natural or city gas

✓1 adapter “C” for L.P.G.

✓gaskets “D”, “E” and “F”

The hob must be installed in a room

with adequate ventilation (see page 13).

Make sure the tube is snugly fit at both

ends and use a standard tube clamp

(not supplied) to fasten it.

IMPORTANT:

✓Never attempt to turn the elbow

“A” without having first slackened

off the relative lock nipple.

✓The seals “D-E-F” (fig. 18) are the

elements that guarantees the seal

in the gas connection.

It is recommended that they be

replaced whenever they shows

even the slightest deformation or

imperfection.

✓After connecting to the mains,

check that the couplings are

correctly sealed, using soapy

solution, but never a naked flame.

✓The connection with rigid metal

pipes should not cause stresses to

the hob ramp.

✓If the rubber tube is used for the

gas connection:

- Make sure the tube is snugly fit

at both ends and use a standard

tube clamp (not supplied) to

fasten it.

- The rubber tube must be as short

as possible, without contractions

or kinks.

- The rubber tube must never be at

any point in its lenght in contact

with the “hot” parts.

- From time to time check to make

sure that the rubber is in perfect

condition and substitute it at

printed due date or if it shows

signs of wearing or damage.

OPERATIONS TO BE PERFORMED

WHEN SUBSTITUTING THE

INJECTORS

If the injectors are not supplied they

can be obtained from the “Service

Centre”.

✓Remove the gratings and the burner

covers;

✓Using a wrench, substitute the

nozzle injectors “J” (Fig. 20) with

those most suitable for the kind of

gas for which it is to be used (see

Injector table).

The burners are conceived in such a

way so as not to require the

regulation of the primary air.
