below and fig. 2).
- When boiling point is reached, turn the knob to the
“Minimum” position (small flame fig. 1).
- Always use pans with lids.
“DUAL” burner:
separate regulation of the inner and outer rings (in
practical terms, a dual burner controlled by a single
knob), offering very flexible use thanks to the
possibility to light either the inner flame only or the
whole burner (inner and outer flame at the same
time).
LIGHTING AND USING THE “DUAL” BURNER
Stand the pan on the burner before lighting.
Despite being controlled by a single knob, the
“DUAL” burner can be used in two different ways.

USE
Notes:
use of a gas cooking appliance produces heat and moisture in the room in which it is installed.
The room must therefore be well ventilated.
Intensive and lengthy use of the appliance may require additional ventilation. This can be
achieved by opening a window or by increasing the power of the mechanical exhausting system if
installed.
WARNING!
NEVER use this appliance as a space heater
to heat or warm the room. Doing so may result
in carbon monoxide poisoning and
overheating ot the oven.

CLEANING
CAUTION:
before cleaning the appliance, disconnect it
from the gas and electricity supplies.
- Traces of liquid spilled from pans can be
eliminated with vinegar or lemon juice.
- Never allow sugar or sugary foods to fall on the
hob while cooking. Should this occur, switch off
the hob and clean it immediately with hot water,
using a scraper on hot spills.
4) WORKTOP
If you wish to maintain the shine of the ceramic
surface, treat the glass with a silicon-based film
product before use to protect the surface against
water and dirt. This protective film is not durable,
so it is advisable to repeat the application of the
product frequently.
- As time goes by metallic reflections, colouring or
scratches may appear due to poor cleaning and
the incorrect movement of pans. Scratches are
hard to eliminate but do not affect the correct
operation of your hob.
- Do not use jets of steam to clean the appliance.
It is very important to clean the hob every time you
use it, while the glass is still warm.
Do not clean using abrasive metal scourers, powder
abrasives or corrosive sprays.
Depending on the degree of dirt, we recommend:
- for light stains, a damp sponge is sufficient.
- Tough, encrusted dirt is easily eliminated using a
scraper (fig. 3), not supplied with the hob, but
easy to find in local stores. Use the scraper
carefully to avoid damaging the hob.

CLEANING
The enamelled grids, enamelled covers “A”, “B” and
“C”, and burner heads “M” (see fig. 4 and 4/A) must
also be washed and the ignition elements “AC” and
safety cut-off sensors “TC” (see fig. 4/B) must be
cleaned. Do not wash them in the dishwasher.
Cleaning operations must be carried out when the
hob and components are not hot and the use of
metal scouring pads, powder abrasives and
corrosive sprays must be avoided.
- If the opening and closing of any valve is
awkward, do not force it but request urgent
intervention by the technical assistance
service.
- Do not use jets of steam to clean the
appliance.
- To prevent difficulties with lighting, regularly
clean the ignition elements (ceramic and
electrode) and safety cut-off devices.
Do not allow vinegar, coffee, milk, salt water, lemon
juice or tomato juice to remain in prolonged contact
with the surfaces.
IMPORTANT:
when removing the burners to clean them, ensure
that all parts are correctly positioned before
relighting them. In particular for the “Dual” burner,
never remove the central disc underneath the
lid (particular A - fig. 5), for cleaning. Should this
operation be necessary, it must be carried out
exclusively by qualified personnel.
WARNINGS:
when reassembling the components, observe
the following recommendations:
- check that the holes in the burner heads “M”
(fig. 4) are not blocked by foreign bodies.
- Ensure that the enamelled covers “A”, “B”
and “C” (fig. 4 and 4/A) are correctly
positioned on the burner head. The covers are
correctly positioned on the head when they
are perfectly stable.
Do not remove the metal disc “B” screwed onto the
burner.
