How T o Use Y our Appliance

The position of the corresponding gas burner or electric
hot plate (if present) is indicated on each control knob.

Gas Burners

The burners differ in size and power. Choose the most
appropriate one for the diameter of the cookware being
used.
The burner can be regulated with the corresonding control
knob by using one of the following settings:

• Off
High

Low

T o turn on one of the burner s, place a lighted match or
lighter near the burner, press the knob all the wa y in and
turn in the counter-clockwise direction to the "High" setting.
On those models fitted with a safety device (F), the
knob must be pressed in for about 6 seconds until the
device that keeps the flame lighted w arms up.
On those models fitted with an ignitor (D), the "E" ignition

button, identified by the symbol, must first be pressed
and then the corresponding knob pushed all the way in

and turned in the counter-clockwise direction to the "High"
setting.
Some models are equipped with an ignition switch
incorporated into the control knob. If this is the case, the

ignitor (D) is present, but not the "E" switch (the symbol
is located near each knob).

T o light a b urner, simply press the corresponding knob all
the way in and then turn it in the counter-clockwise
direction to the "High" setting, keeping it pressed in until
the burner lights.
Caution: If the burner accidently goes out, turn off the
gas with the control knob and try to light it again after
waiting at least 1 minute.
To turn off a burner, turn the knob in the clockwise
direction until it stops (it should be on the “•” setting).

Electric Hot Plates (only on certain models)
The hot plates vary in diameter and power: "normal" and
"fast". The latter can be identified by a red boss in the
center of the hot plate itself.
The hot plate can be regulated by turning the
corresponding knob in the clockwise or counter-clockwise
direction to any one of the 6 different settings:

0 Off
1 Low
2-5 Medium
6 High

The section entitled, "Practical Cooking Advise", provides
information on the recommended settings for various types
of food or cooking processes.
When the knob is on any of the settings other than "Off",
the "H" operating light comes on.

Cooktop Broiler (only on certain models)
The broiler can be regulated by turning the corresponding
knob in the clockwise or counter-clockwise direction to any
of the 12 possible settings:

0 Off
1 Low
2-11 Medium

How to Keep Your Cooktop in Shape

Before cleaning or performing maintenance on your
appliance, disconnect it from the electrical power supply.

To extend the life of the cooktop, it is absolutely
indispensable that it be cleaned carefully and
thoroughly on a frequent basis, keeping in mind the
following:

• The enameled parts and the glass top, if present, m ust
be washed with warm water without using abrasive
powders or corrosive substances which could ruin
them;

• The removable parts of the burners should be washed
frequently with warm water and soap, making sure to
remove caked-on substances;

• On cooktops with automatic ignition, the end of the
electronic ignition device must be cleaned carefully and
frequently, making sure that the gas holes are not
clogged;

• The electric hobs should be cleaned using a damp cloth
and then rubbed with oil while still warm;

• Stainless steel can be stained if it remains in contact

14

with highly calcareous water or aggressive detergents
(containing phosphorous) for an extended period of
time. It is recommended that these parts be rinsed
thoroughly with water and then dried well. It is also a
good idea to clean up any spills;

• Before using the ceramic glass module, the surface
must be cleaned, using a damp cloth to remove dust
or food residues. The ceramic glass surface should be
cleaned regularly with a soultion of warm water and a
non-abrasive detergent. P eriodically, special products
will need to be used to clean the surface. First, remov e
all food buildup or grease with a cleaning scraper , e .g.

(not supplied) (Fig. A).

Clean the cooking surface when it is still warm with a
suitable cleaning product and paper towels. Then rub
with a damp cloth and dry . Alumin um foil, plastic items,
objects made of synthetic material, sugar or foods with
a high sugar content that have melted onto the surf ace
must be removed immediatley with a scraper while
the cooking surface is still hot. Special cleaning
products for ceramic glass surf aces form a transparent
protective layer which fights diry buildup. This also
protects the surface from damage caused by f ood with
a high sugar content. Do not use abrasiv e sponges or
cleaning products under any circumstances. This holds
true for chemically aggressive cleaners, like oven
sprays and stain remov ers (Fig. B);

Fig. A Fig. B

• When cleaning the grill, it is recommeded that you do

so while it is still hot, using the handles provided to
move it from the cooktop to the sink. To remove the
pan beneath the grill, it is a good idea to wait until the
heating element has cooled (roughly after 15 minutes).

Greasing the Gas Valves

Over time, the gas valv es ma y stick or become difficult to
turn. If this is the case, the must be cleaned on the inside
and the regreased.

N.B.: This procedure m ust be performed by a technician
authorized by the manufacturer.

Practical Advice on Using the Half Fish-Kettle Burner

The two central burners, or Half Fish-Kettle burners, are
eliptic in form and can be turned up to 90°. This makes
the cooktop more flexible in terms of how it can be used.

To turn the two central burners 90°, proceed as follows:

• Make sure that the burners are cool;

• Lift the burner completely out of its housing;

• Replace it in its housing in the position desired;

• Make sure that the burners are positioned correctly
before use.

In addition, the two cetnral burners can be used in tandem
or speartely with cookware of different shapes and sizes:

• Double burner for a fish-kettle or oval cookware (Fig. A).

• Double burner for a griddle or rectangular/square
cookware with minimum dimensions of 28x28 cm
(Fig. B)

• Double burner for large cookware (diameter of 26-28
cm) (Fig. C).

• Single burner for medium size cookware (diameter of
16-20 cm) (Fig. D).

For best performance, keep in mind the following:

• All types of casseroles can be used on the ceramic
glass cooking surface. Howe ver , it is important that the
bottom be perfectly flat. Casseroles with thicker bottoms
distribute heat more evenly.

• Use cookware the diameter of which is at least as large

as the cooking area so that all of the heat produced by
the heating element is used.

• Make sure that the bottom of the pot is always dry and
clean to insure good contact between the cookware
and the cooking surface. This will also increase the life
of the pots and of the ceramic glass surface as well.

• Do not use the same cookware that you use for gas
burners because the concentrated heat they produce
can deform the bottom of the pot. Therefore, you will
not achieve best results when using these pots on the
ceramic glass surface.

Notice: The glue used to seal the glass surf ace may leav e
traces on the appliance. We recommend that the module
be cleaned with a non-abrasive cleaner before being used
the first time. During the first few hours of use, you may
detect the smell of rubber; this will disappear after a short
time.

Is there a problem?

It may occur that the cooktop does not function or does
not function properly . Before calling customer service for
assistance, lets see what can be done.
First of all, check to see that there are no interruptions in
the gas and electrical supplies, and, in particular, that the
gas valves for the mains are open.

Installation Instructions for built-in

The following instructions are directed at the qualified
installer so that the installation and maintenance
proceedures may be follo wed in the most professional and
expert manner possible. Important: Unplug the electrical

connection before performing any maintenance or
regulation upkeep work.

Positioning for gas hob
Important: this unit may be installed and used only in

permanently ventilated rooms according to the British
Stancards Codes Of Practice: B.S. 6172 / B.S. 5440, Par.
2 and B.S. 6891 Current Editions. The following
requirements must be observed:

a) The room must be fitted with a ventilation system which

vents smoke and gases from combustion to the outside .
This must be done by means of a hood or electric
ventilator that turns on automatically each time the hood
is operated.

In a chimney stack or branched flue. Directly to the Outside
(exclusively for cooking appliances)

b) The room must also allow for the influx of the air needed

for proper combustion. The flow of air for combustion
purposes must not be less than 2 m3/h per kW of installed
capacity . The supply of said air can be effected b y means
of direct influx from the outside through a duct with a
inner cross section of at least 100 cm² which must not be
able to be accidentally block ed. Those appliances which
are not fitted with a safety device to prevent the flame
from accidentally going out must have a ventilation
opening twice the size otherwise required, i.e. a minimum
of 200cm2 (Fig. A). Otherwise, the room can be vented
indirectly through adjacent rooms fitted with ventilation
ducts to the outside as described above, as long as the
adjacent rooms are not shared areas, bedrooms or
present the risk of fire (Fig. B).

Fig. A Fig. B

c) Intensive and prolonged use of the appliance may ne-

cessitate supplemental ventilation, e.g. opening a window
or increasing the power of the air intake system (if present).

d) Liquidified petroleum gases are heavier than air and, as

a result, settle downwards. Rooms in which LPG tanks
are installed must be fitted with ventilation openings to
the outside in order to allow the gas to escape in the
event of a leak. Theref ore, LPG tanks , whether empty or
partially full, must not be installed or stored in rooms or
spaces below ground lev el (cellars, ect.). It is also a good
idea to keep only the tank currently being used in the
room, making sure that it is not near sources of heat
(ovens, fireplaces, sto ves, etc.) that could raise the internal
temperature of the tank above 50°C .

Installation of built-in stove tops

The gas hobs are prepared with protection degree against
excessive heating of type X, the appliance can therefore
be installed next to cabinets, provided the height does not
exceed that of the hob. For a correct installation of the
cooking hob the following precautions must be f ollow ed:
a) The hob may be located in a kitchen, a kitonen/diner

or bed sitting room, but not in a bathroom or shower
room.

b) The fur niture standing next to the unit, that is higher

than the working boards, must be placed at least
110mm from the edge of the board.

c) The cabinets should be positioned next to the hood at

a height of at least 420 mm (Fig. C).

f) In the event the cooktop is not installed above a b uilt-

in oven, a wood panel must be inserted as insulation.
This panel must be placed at least 20 mm from the

bottom of the cooktop itself.
Important: When installing the hob abov e a built-in ov en,
the oven should be placed on two wooden strips; in the
case of a joining cabinet surface, remember to leave a
space of at least 45 x 560 mm at the back.

560 mm.

When installing on a built-in oven without f orced ventilation,
ensure that there are air inlets and outlets for ventilating
the interior of the cabinet adequately .

Gas connection for gas hob

The cooker should be connected to the gas-supply by a
corgi registered installer. During installation of this product
it is essential to fit an approved gas tap to isolate the supply
from the appliance for the conv enience of any subsequent
removal or servicing. Connection of the appliance to the
gas mains or liquid gas must be carried out according to
the prescribed regulation in force, and only after it is

ascertained that it is adaptable to the type of gas to be
used. If not, follow the instructions indicated in the
paragraph headed “Adaptation to different gas types”. In
the case of connection to liquid gas, by tank, use pressure
regulators that conform to the regulation in force.
Important: For safety, for the correct regulation of gas use
and long life of the appliance, ensure that the gas pressure
conforms to the indications given in table 1 “Nozzle and
burner characteristics”.

Connection to non-flexible tube

(copper or steel)
Connection to the gas source must be done in such a way
as to not create any stress points at any part of the
appliance.
The appliance is fitted with an adjustable, "L" shaped
connector and a gasket for the attachment to the gas supply .
Should this connector have to be turned, the gasket must be
replaced (supplied with the appliance).
The feeding connector of the gas to the appliance is
threaded 1/2 gas male cylinder.

Connection to flexible steel tube

The gas feed connector to the appliance is a threaded,
male 1/2" connector for round gas pipe. Only use pipes
and sealing gaskets that that conform to the standards
currently in force. The maximum length of the flexible pipes
must not exceed 2000 mm. Once the connection has been
made, ensure that the flexib le metal tube does not touch
any moving parts and is not crushed.

Check the Seal

Once the appliance has been installed, make sure all the
connections are properly sealed, using a soapy water
solution. Ne v er use a flame .

Electrical Connection

The cooktops fitted with a tripolar electrical supply cord
are designed to be be used with alternating current
according to the indications on the rating plate located
under the cooktop. The earthing wire can be identified by
its yellow-green colour .
In the case of installation over a b uilt-in electric oven,
the electrical connections for the cooktop and oven
should be independent, not only for safety purposes, b ut
also to facilitate remov al of one or both in the future .

Electrical Connection for Gas Cooktop

Fit the supply cord with a standard plug for the demand
rate indicated on the rating plate or connect it directly to
the electrical mains. In the latter case , a single pole switch
must be placed between the appliance and the mains,
with a minimum opening between the contacts of 3 mm in
compliance with current safety codes (the earthing wire
must not be interrupted by the switch). The power supply
cord must be positioned so that it does not reach a tem­perature in excess of 50°C above room temperature at
any point.
Before actual connection make sure that:

• The fuse and electrical system can withstand the load

required by the appliance;

• That the electrical supply system is equiped with an

efficient earth hook-up according to the norms and
regulations prescribed by law;

20

• That the plug or switch are easily accessible.

Important: the wires in the mains lead are coloured in
accordance with the following code:
Green & Yellow - Earth
Blue - Neutral
Brown - Live
As the colours of the wires in the mains lead may not
correspond with the coloured markings identifying the
terminals in your plug, proceed as follows:
Connect the Green & Yellow wire to terminal marked “E”

or or coloured Green or Green & Yellow.
Connect the Brown wire to the terminal marked “L” or

coloured Red.
Connect the Blue wire to the terminal marked “N” or
coloured Black.

Adapting the Cooktop for Different T ypes of Gas

To adapt the cooktop to a different type of gas than that
for which it was designed, (see the stic k er under the hob
or on the packaging), the burner nozzles must be changed,
as follows:

• Remove the pan supports and slide the burners out of

the cooktop.

• Unscrew the nozzles using a 7mm sock et wrench and

replace them with those for the new type of gas. (See
table 1, “Burner and Nozzle Specifications”).

• Reassemble the parts following the instructions in

reverse order.

• On completing the operation, replace the old rating label

with the one showing the new type of gas; the sticker

is availab le from our Service Centres.
If the gas pressure is different than that prescribed, a
pressure regulator must be installed at the source, in
compliance with national standards governing the use of
piped gas regulators.

Regulation of Air Supply to the Burner

The burners do not need any primary air regulator.

Minimum Regulation

Minimum regulation:

• Turn the gas valve to minim um.

• Remove the knob and turn the regulator screw
(positioned either on the side of the top or inside the
shaft - Figs. A and B) cloc kwise until the flame becomes
small but regular.

N.B.: In the case of liquid gas, the regulation screw must
be fully screwed in (clockwise).

• Make sure that, when the knob is turned rapidly high

to low, the flame does not go out.

• In the event of a malfunction on appliances with the

security device (thermocouple) when the gas supply
is set at minimum, increase the minimum supply levels
using the regulator screw in Fig. A - B.

Once the adjustment has been made, apply sealing wax,
or a suitable substitute, to the old seals on the by-pass.
