Some models are equipped with an ignition switch
incorporated into the control knob. If this is the case, the
ignitor(D)is present, butnot the "E" switch(the symbol
is located near each knob).
To light a burner, 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
correspondingknob in theclockwiseor counter-clockwise
direction to any one of the 6 different settings:

How to KeepYour 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:
• Theenameled parts andthe glass top,if present, must
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
electronicignitiondevice mustbecleaned carefully and
frequently, making sure that the gas holes are not
clogged;
• Theelectrichobs 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.Periodically, special products
willneed to be used toclean the surface. First,remove
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
witha damp cloth and dry.Aluminumfoil,plastic items,
objectsmade of synthetic material, sugar orfoodswith
ahigh sugar content that have melted onto the surface
must be removed immediatley with a scraper while
the cooking surface is still hot. Special cleaning
productsforceramicglass surfacesforma transparent
protective layer which fights diry buildup. This also
protects the surface from damage caused by food with
a high sugar content. Do not use abrasive sponges or
cleaningproductsunder anycircumstances.Thisholds
true for chemically aggressive cleaners, like oven
sprays and stain removers (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
heatingelement has cooled (roughlyafter 15 minutes).
Greasing the GasValves
Over time, the gas valves may stick or become difficult to
turn.If this is the case, the must be cleaned on the inside
and the regreased.
N.B.:This proceduremustbeperformedbyatechnician
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
beforeuse.
Inaddition, the twocetnralburners can beused 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).

bottombeperfectly flat.Casseroleswith thickerbottoms
distribute heat more evenly.
•Usecookwarethe diameterof which is atleast 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:Theglueused to sealthe glass surfacemayleave
traces on the appliance.We recommend that the module
becleaned with anon-abrasivecleaner beforebeing 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.

Installation Instructions for built-in
The following instructions are directed at the qualified
installer so that the installation and maintenance
proceeduresmaybe followedinthe most professional and
expertmannerpossible.Important: Unplug the electrical
connection before performing any maintenance or
regulation upkeep work.
Positioning forgas 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
ventilatorthat turnson automatically each timethe 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
purposesmustnotbelessthan2m3/hperkWofinstalled
capacity.Thesupply ofsaidaircanbe effectedbymeans
of direct influx from the outside through a duct with a
innercross section ofatleast100cm²which mustnotbe
able to be accidentally blocked.Those appliances which
are not fitted with a safety device to prevent the flame
from accidentally going out must have a ventilation
openingtwicethesizeotherwiserequired,i.e.aminimum
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).

c) Intensive and prolonged use of the appliance may ne-
cessitatesupplementalventilation,e.g.openingawindow
orincreasingthepoweroftheairintakesystem(ifpresent).
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.Therefore, LPG tanks, whether empty or
partially full, must not be installed or stored in rooms or
spacesbelowgroundlevel(cellars,ect.).It isalsoagood
idea to keep only the tank currently being used in the
room, making sure that it is not near sources of heat
(ovens,fireplaces,stoves,etc.)thatcouldraisetheinternal
temperature of the tank above 50°C.
Installation of built-in stove tops
Thegas hobs are preparedwith protection degreeagainst
excessive heating of type X, the appliance can therefore
beinstalled nextto cabinets, provided the height does not
exceed that of the hob. For a correct installation of the
cooking hob the following precautions must be followed:
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 furniture 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).

Gas connection for gas hob
The cooker should be connected to the gas-supply by a
corgiregistered installer.Duringinstallationof this product
itisessentialtofitanapprovedgastaptoisolatethe supply
fromthe appliance for the convenience of anysubsequent
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
thecase of connection to liquidgas,bytank,use pressure
regulators that conform to the regulation in force.
Important: Forsafety,forthe correct regulation ofgas use
andlonglifeof the appliance,ensure that thegaspressure
conforms to the indications given in table 1 “Nozzle and
burner characteristics”.
Connection to non-flexible tube

and sealing gaskets that that conform to the standards
currentlyinforce.Themaximumlengthof the flexiblepipes
mustnot exceed2000 mm. Once the connectionhasbeen
made, ensure that the flexible 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.Never use a flame.
ElectricalConnection
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 built-in electric oven,
the electrical connections for the cooktop and oven
should be independent, not only for safety purposes, but
also to facilitate removal 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
theelectrical 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 tem-
perature 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 DifferentTypes of Gas
To adapt the cooktop to a different type of gas than that
for which it was designed, (see the sticker under the hob
oronthepackaging),theburner nozzles must be changed,
as follows:
•Remove the pan supports and slide the burners out of
the cooktop.
•Unscrew the nozzles using a 7mm socket 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.
•Oncompleting the operation,replacetheoldratinglabel
with the one showing the new type of gas; the sticker
is available 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.
MinimumRegulation
Minimum regulation:
•Turn the gas valve to minimum.
• Remove the knob and turn the regulator screw
(positioned either on the side of the top or inside the
shaft-Figs.A and B)clockwiseuntil 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
isset 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.
