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:

• Do not use steam equipment to clean the appliance.

• 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;

Practical Advice

Practical Advise on Using the Burners

For best performance, f ollo w 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".

• 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 ma y become difficult to
turn. If so , the tap itself m ust be replaced.

N.B.: This operation m ust be performed by a technician
authorised by the manufacturer.

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, P ar.
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.

Detail A Adjacent Room to be

Room Vented

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. Therefore, 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 , stoves, etc.) that could raise the internal
temperature of the tank above 50°C .

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).

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 cooker , the f ollowing precautions must be tak en:
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) The cabinets installed next to the hood must be located

at a height of at least 420 mm from the top, (as sho wn
in Fig. C).

f) In the event the cooktop is not installed abov e 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.
Important: When installing the cooktop above a built-in
oven, the ov en 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.

d) Should the cooktop be installed directly under a

cupboard, the latter should be at least 700 mm
(millimetres) from the top, as shown in Fig. C.

e) The dimensions of the cutout for the appliance must

be those indicated in the figure D . Clamps are pro vided
to fasten the cooktop to counters measuring from 20
to 40 mm in thickness. To fasten the cooktop securely,
it is recommended that all the clamps be used.

When installing the cooktop above a built-in ov en without
forced ventilation, ensure that there are air inlets and
outlets for ventilating the interior of the cabinet adequately .

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 conv enience 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, mak e sure that gas pressure levels comply with
the indications given in Table 1, “Nozzle and Burner
Specifications”.
