NOTICE
The stainless steel grease pan and the cast-iron grill, located in the burner and grate packing box, must be
installed, respectively, below and above the electric heating element so that tile element is enclosed
between the two.
How To Use Your 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 corresponding control knob by using one of tile following settings:
OFF
High
Low
4

To turn on one of the burners, place a lighted match or lighter near the burner, press the knob all the
way 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 warms 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).
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).
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, 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 electronic ignition device must be cleaned carefully
and frequently, making sure that the gas holes are not clogged;
●Stainless steel can be stained if it remains in contact 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 solution of warm water and
a non-abrasive detergent, periodically, special products will need to be used to clean the surface. First,
remove all food buildup or grease with a cleaning scraper, e.g.
CERA (not supplied) (Fig. 1).
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. Aluminum foil, plastic items, objects made of synthetic material, sugar or
foods with a high sugar content that have melted onto the surface must be removed immediately with a
scraper while the cooking surface is still hot. Special cleaning products for ceramic glass surfaces form a
transparent protective layer which fights dirty buildup. This also protects the surface from damage caused
by food with a high sugar content. Do not use abrasive sponges or cleaning products under any
circumstances. This holds true for chemically aggressive cleaners, like oven sprays and stain removers
(Fig.2);

Fig.1 Fig.2
●When cleaning the grill, it is recommended 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 valves may stick or become difficult to turn. If this is the case, they must be cleaned on
the inside and then regreased
N.B.:This procedure must be performed by a technician authorized by the
manufacturer.
Practical Advice
Practical Advice on Using the Burners
For best performance, follow these general guidelines:
●Use the appropriate cookware for each burner (see table) in order to prevent the flame from reaching the
sides of the pot or pan;
●Always use cookware with a flat bottom and keep the lid on;
●When the contents come to a boil, turn the knob to "Low".
Burner
Ø Cookware diameter (cm)
Semi–rapid burner 16 - 20
Auxiliary burner 10- 14
Rapid burner 16 - 20
Triple ring wok burner
24 - 26
To identify the type of burner, refer to the designs in the section entitled, "Burner and Nozzle Specifications".
Practical Advice on Using the Half Fish-Kettle Burner
The two central burners, or Half Fish-Kettle burners, are elliptic 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 central burners can be used in tandem or separately with cookware of different
For best performance, keep in mind the following:

●All types of casseroles can be used on the ceramic glass cooking surface. However, 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 tile 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 surface may leave 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, let’s 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.
The burner does not light or the flame is not uniform around the burner.
Check to make sure that:
●The gas holes on the burner are not clogged;
●All of the movable parts that make up the burner are mounted correctly;
●There are no draughts around the cooking surface.
The flame does not stay lighted on the model with the safety device.
Check to make sure that:
●You press the knob all the way in;
●You keep the knob pressed in long enough to activate the safety device.
●The gas holes are not clogged in the area corresponding to the safety device.
The burner does not remain on when set to "Low".
Check to make sure that:
●The gas holes are not clogged.
●There are no draughts near tire cooking surface.
7

●Tile minimum has been adjusted correctly (see the section entitled, "Minimum Regulation").
The cookware is not stable.
Check to make sure that:
●The bottom of the cookware is perfectly flat.
●The cookware is centered correctly on the burner or electric hot plate.
●The support grids have not been inverted.
Installation Instructions for built-in
The following instructions are directed at the qualified installer so that the installation and maintenance
procedures may be followed 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
Standards 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 by means of direct influx from the outside through a duct with an inner cross section of
at least 100cm² which must not be 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
opening twice the size otherwise required, i.e. a minimum of 200 cm² (Fig. 3). 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. 4).

Fig.3Fig.4
c) Intensive and prolonged use of the appliance may necessitate 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. Therefore, LPG tanks, whether empty or partially full, must not be
installed or stored in rooms or spaces below ground level'(cellars, etc.). 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, stoves, etc.) that could raise the internal
temperature of the tank above 50ºC.
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 followed:
a) The hob may be located in a kitchen, a ketone/diner or bed sitting room, but not in a bathroom or shower
room.
b) The furniture standing next to the unit, that is highe1 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. 5).
Fig.5
d) Should the hob be installed directly under a cupboard the letter should be at least 700mm (millimeters)
from the worktop, as shown in Fig. C.
e) The dimensions of the room for the furniture must those indicated in the figures in the last two pages the
cover. Fixing hooks are provided which allow place the hob plate on work tops that measure 20 to 40 mm
in thickness (see Fig. 6).To obtain a of the hob plate it is advisable to use all the fixing supplied.

f) In the event the cooktop is not installed above a built-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.
lmportant: When installing the hob above a built-in oven, 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.
When installing on a built-in oven without forced 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 convenience
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 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 flexible
metal tube does not touch any moving parts and is not crushed.
Check the Seal
11

Once the appliance has been installed, make sure all the connections are properly sealed, using a soapy
water solution. Never use a flame.
Electrical Connection
The cooktops fitted with a tripolar electrical supply cord are designed to 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 color.
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 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 equipped with an efficient earth hook-up according to the norms and
regulations prescribed by law;
●That the plug or switch are easily accessible.
Important: the wires in the mains lead are colored in accordance with the following code:
Green & Yellow - Earth
Blue - Neutral
Brown - Live
As the colors of the wires in the mains lead may not correspond with the colored markings identifying the
terminals in your plug, proceed as follows: Connect the Green & Yellow wire to terminal marked "E"
or or colored Green or Green & Yellow.
Connect the Brown wire to the terminal marked "L" or colored Red.
Connect the Blue wire to the terminal marked "N" or colored Black.

Note.
It is up to the used to request converting the appliance to another gas type if so required by the local conditions at a
licensed gas fitter/ service.
Flame selection
At the burners adjusted correctly, the flames should be light blue, and the inner cone should be clearly visible. The
size of flame depends on the position of the related burner control knob.
-Burner ON，large flame -Burner ON，small flame（saxing mode）-Burner OFF
Fig.8
See also fig.8 for various operating options (flame size selection); the burner should be set at a large flame during
the initial phase of cooking to bring the food to boiling, and then the knob should be turned to the saving flame
position to maintain the cooking. It is also possible to adjust the flame size stepless.
It is prohibited to adjust the flame in the range between the Burner OFF and Burner ON large flame
positions.
Significant quantities of energy can be saved if the appliance is used correctly, parameters set correctly, and
appropriate cookware is used. The savings can be as follows：
·Up to 60 per cent savings when proper pots are used,
·Up to 60 per cent savings when the unit is operated correctly and the suitable flame size is
chosen.
It is a prerequisite for efficient and energy-saving operation of the cooktop that the burners are kept clean at all times
(in particular the flame slots and nozzles). Adapting to different types of gas
