60 seconds before lighting it

again.

Correct positioning of the flame­spreader crowns and burner caps

Before lighting the cooktop burners, make
sure that the flame-spreader crowns are
correctly positioned in their housings with
their respective burner caps. Make sure that
the holes in the burners are aligned with the
igniters and thermocouples. Also ensure that
the flame-spreader crowns are correctly
engaged in the burner holes.

EN

13

Use

Correct positioning of the grids

To install the grids follow the instructions and
the following figures.

1. Lay the lateral grids on the cooktop
paying attention to position the front teeth
facing the knobs.

2. Lay the centre grid engaging the notches
in the teeth of the lateral grids.

In addition, pay attention to the mark
"FRONT" under each grid at the front, as a
further help to correctly position the grids on
the cooktop.

• Position the grids so that the marks
"FRONT" are facing the cooktop knobs.

14

Practical tips for using the cooktop

Use

For better burner efficiency and to minimise
gas consumption, use pans with lids and of
suitable size for the burner, so that the
flames do not reach up the sides of the pan.
Once the contents come to the boil, turn
down the flame far enough to ensure that
the liquid does not boil over.

Cookware diameters:

• Aux.: 12 - 18 cm.

• Semi rapid: 14 - 24 cm.

• Rapid: 20 - 26 cm.

• Ultra-rapid: 20 - 30 cm.

To prevent burns or damage to the cooktop
or the counter top during cooking, all pans
or griddles must be placed inside the
perimeter of the grids.

4.1 Instructions

Improper use

Risk of damage to surfaces

• Do not use steam jets to clean the
appliance.

• Do not use cleaning products containing
chlorine, ammonia or bleach on parts
made of steel or that have metallic
surface finishes (e.g. anodizing, nickel­or chromium-plating).

• If it comes into contact with aggressive
detergents, hard water or spills (cooking
water, sauces, coffee, etc.), clean
immediately after having let the cooktop
cool down.

• Do not use rough or abrasive materials
or sharp metal scrapers.

• Do not wash the removable
components such as the cooktop grids,
flame-spreader crowns and burner caps
in a dishwasher.

4.2 Cleaning the appliance

To keep the surfaces in good condition,
they should be cleaned regularly after use.
Let them cool first.

Ordinary daily cleaning

Always use specific products only that do
not contain abrasives or chlorine-based
acids.

Pour the product onto a damp cloth and
wipe the surface, rinse thoroughly and dry
with a soft cloth or a microfibre cloth.

Food stains or residues

Do not use steel sponges and sharp
scrapers, as they will damage the surfaces.

Use normal, non-abrasive products and a
wooden or plastic tool, if necessary. Rinse
thoroughly and dry with a soft cloth or a
microfibre cloth.

Annual service by an authorised
person is recommended, or if any
of the following conditions are
noticed; incomplete ignition,
appreciable yellow tipping,
carbon deposition, lifting, floating,
lighting back or objectionable
odour.

16

Cleaning and maintenance

Cooktop grids

Remove the grids and clean them in
lukewarm water and non-abrasive
detergent. Make sure to remove any
encrustations. Dry them thoroughly and
return them to the cooktop.

The continuous contact between
the grids and the flame can cause
modifications to the enamel over
time in those parts exposed to
heat. This is a completely natural
phenomenon which has no effect
on the operation of this
component.

Igniters and thermocouples

For correct operation the igniters and
thermocouples must always be perfectly
clean. Check them frequently and clean
them with a damp cloth if necessary.
Remove any dry residues with a wooden
toothpick or a needle.

Flame-spreader crowns and burner caps

For easier cleaning, the flame-spreader
crowns and the burner caps can be
removed.

Wash them in hot water and non-abrasive
detergent. Carefully remove any
encrustation, then wait until they are
perfectly dry. Refit the flame-spreader
crowns making sure that they are correctly
positioned in their housings with their
respective burner caps.

Knobs

Do not use aggressive products
containing alcohol or products for
cleaning steel and glass when
cleaning the knobs, as these
products could cause permanent
damage.

The knobs should be cleaned with a soft
cloth dampened with warm water, then
dried carefully. They can easily be removed
by pulling them upwards.

5.7 Adaptation to different types of

gas

If other types of gas are to be used, the
nozzles must be replaced and the primary
air must be adjusted. In order to replace the
nozzles and adjust the burners, the hob top
must be removed.

Removing the hob top

1. Remove the grids from the top; first the
centre one than the lateral ones.

3. Pull the knobs upwards to remove them.

EN

4. Only for models with lateral UR: lift the

appliance from its housing and turn it
upside down.

5. Only for models with lateral UR: remove

the bracket fixing screw.

2. Remove the flame-spreader crowns and
relative burner caps.

27

Installation

6. Only for models with lateral UR: pull out

the bracket.

7. Only for models with lateral UR: put the

appliance back in normal position.

8. For each burner, unscrew the three
screws that fix the burner plates to the
hob top.

9. Remove the seals from the plugs and
thermocouples of each burner.

10. Lift the hob top and remove it.

Replacing nozzles

28

1. Undo the burner work surface fastening
screw.

2. Remove the burner work surface and the
corresponding gas supply hose.

Installation

3. Lift the trigger of the microswitch for the
gas tap (1) then remove it (2).

4. Use a 7-mm spanner to remove the
nozzle and replace it with the new one
for the required gas supply, following the
indications given in the relevant tables
(see Burner and nozzle specifications
tables”).

Primary air adjustment

After removing the top, proceed as follows:

1. Loosen the screw A. Adjust the air flow
by moving the air regulator B to obtain
the distance C given in the relevant table
(see “Burner and nozzle specifications
tables”).

2. After adjusting each burner, reassemble
the appliance correctly.

EN

The nozzle tightening torque must
be no more than 3 Nm.

29

Installation

Adjusting the minimum setting for natural
gas

Light the burner and turn it to the minimum
position. Extract the gas tap knob and turn
the adjustment screw next to the tap rod
(depending on the model) until the correct
minimum flame is achieved.

Refit the knob and verify that the burner
flame is stable. Turn the knob rapidly from
the maximum to the minimum setting: the
flame should not go out. Repeat the
operation on all gas taps.

Adjusting the minimum setting for LPG

• Tighten the screw located at the side of
the tap rod clockwise all the way.

Following adjustment to a gas
other than the one originally set in
the factory, replace the gas setting
label fixed to the appliance with
the one corresponding to the new
gas. The label is inserted inside the
nozzle pack (where present)

Lubricating the gas taps

Over time the gas taps may become difficult
to turn and get blocked. Clean them
internally and replace the lubrication
grease.

Lubrication of the gas taps should
be performed by a specialised
technician.
