How To Use Your Appliance
The position of the corresponding gas burner or electric
hot plate (if present) is indicated on each control knob.
To light a burner, simply press the corresponding knob
all the way in and then turn it anti-clockwise to the
"High" setting, keeping it pressed in until the burner
lights.
Caution: If the burner accidently goes out, turn off the
gas on the control knob and wait at least 1 minute before
you try to to light it again.
To turn off a burner, turn the knob clockwise until it stops
(it should be on the “•” setting).
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
The “separate double flame” burner (only on some
models)
This burner consists of two concentric burners which can
operate either together or separately.
Use of the double flame on the maximum setting gives a
very high power which reduces cooking times with respect
to conventional burners.
Moreover the double flame crown provides a more uniform
distribution of heat on the bottom of the pan, when using
both burners on minimum.
Pots and pans of all sizes can be used. In the case of the
smaller pots and pans we recommend the use of only the
internal burner.
There is a separate control knob for each of the “separate
double flame” burners.
High
Low
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 it anti-clockwise 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 lit 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 anti-clockwise to the "High"
setting.
Some models are equipped with an ignition button
incorporated into the control knob. If this is the case, the
ignitor (D) is present, but not the "E" button.

To turn off a burner, turn the knob clockwise until it stops
(it should be on the “•” setting).
How to Keep Your Hob in Shape
Before cleaning or performing maintenance on your
appliance, disconnect it from the electrical power supply.
To extend the life of the hob, it is absolutely
indispensable that it be cleaned carefully and
thoroughly on a frequent basis, keeping in mind the
following:
· Do not use steam equipment to clean the appliance.
• The enamelled 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 hobs 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
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.
Greasing the Taps
The taps may jam in time or they may become difficult to
turn. If so, the tap itself must be replaced.
N.B.: This operation must be performed by a technician
authorised by the manufacturer.

Practical Advice
Before using the hot plates for the first time, you
should heat them at maximum temperature for
approximately 4 minutes, without any pans. During
this initial stage, their protective coating hardens and
reaches its maximum resistance.
Practical Advise 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;
• Alwasy use cookware with a flat bottom and keep the
lid on;
• When the contents come to a boil, turn the knob to
"Low".

Installation Instructions for built-in
Detail A
The following instructions are intended for the installer so that
the installation and maintenance procedures may be followed in
the most professional and expert manner possible. Important:
Disconnect the appliance from the electrical supply before
performing any maintenance or regulation upkeep work.
Positioning the Cooktop
Important: this unit may be installed and used only in
permanently ventilated rooms in accordance with British
Standard Codes Of Practice: B.S. 6172 / B.S. 5440, Par. 2 and
B.S. 6891 Current Editions.The following requirements must be
observed:
Adjacent
Room
Room to be
Vented
A
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.
Examples of ventilation holes
for comburant air.
Enlarging the ventilation slot
between window and floor.
Fig. A
Fig. B
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, 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, stoves, etc.) that
could raise the internal temperature of the tank above 50°C.
In a chimney stack or branched flue.
Installation of Built-in Cooktops
The appliance can be installed next to furniture units which
are no taller than the top of the cooker hob. The wall in
direct contact with the back panel of the cooker must be
made of non-flammable material. During operation the
back panel of the cooker could reach a temperature of
50°C above room temperature. For proper installation of the
cooktop, the following guidlines must be followed:
a) If the cabinet(s) located next to the cooktop are higher than
the cooktop itself, the cabinet(s) must be installed at least
110 mm from the edge cooktop;
b) Hoods must be installed in accordance with the instructions
contained in the installation manual for the hoods themselves,
and no less than 650 mm from the cooktop;
c) In the case of the 600 mm cooker hoods, besides following
the recommendations in point b), the cabinets should be
positioned next to the hood at a height of at least 540 mm
from the top since this will make it possible to install the lid
and move it correctly.The cabinet should always be installed
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 a inner cross
section of at least 100 cm² 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. 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).

Gas Connection for Cooktop
The cooktop should be connected to the gas supply by an
authorized 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 tanks
must be carried out according to the safety standards currently
in force, and only after it is ascertained that it is suitable for the
type of gas to be used. If not, follow the instructions indicated in
the section entitled, “Adapting the Cooktop for Different Types of
Gas”. If the cooktop is to be connected to tanks containing liquid
gas, use pressure regulators that comply with current safety
standards.
Important: To insure that the appliance operates safety, the gas
is regulated correctly and your appliance lasts over time, make
sure that gas pressure levels comply with the indications given
in Table 1, “Nozzle and Burner Specifications”.

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 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.
Gas Connection to Flexible Steel Pipe
The gas feed connector to the appliance is a threaded, male 1/
2" connector for round gas pipe. Only use pipes, tubes and
gaskets that comply with current safety codes. 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
Once the appliance has been installed, make sure all the
connections are properly sealed, using a soapy water solution.
Never use a flame.
Replacing the nozzles on separate “double flame “
burners:
• remove the grids and slide the burners from their
housings. The burner consists of 2 separate parts (Fig.
C and fig. D);
• unscrew the burers with a 7 mm wrench spanner. The
internal burner has a nozzle, the external burner has
two (of the same size). Replace the nozzle with models
suited to the new type of gas (see table 1).
• replace all the components by repeating the steps in
reverse order.
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 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 making the 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;
• That the plug or switch is 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 the 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.

Regulation of Air Supply to the Burner
The burners do not need a primary air regulator.
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) clockwise
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.
Once the adjustment has been made, apply sealing wax, or a
suitable substitute, to the old seals on the by-pass.
Adapting the Cooktop for Different Types 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 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 socket wrench and
