7. USING THE COOKTOP
Make sure that the burner rings, the burner caps and the grates have
been assembled correctly. Pan stand C(supplied) should be used for
"woks" (Chinese pots).
Adapter B(supplied) is to be used for small vessels.
7.1 Ignition of the burners with safety device
The corresponding burner for each knob is clearly indicated. The
appliance is equipped with an electronic ignition. Simply press and
simultaneously turn the knob counter-clockwise on the low point flame
symbol until the burner is ignited. For models with valves, push and hold
the knob for approximately 2 seconds in order to keep the flame burning
and to activate the safety device. The burner might go off when the knob
is released. If this happens, repeat the previous operation keeping the
knob pressed for more than 2 seconds.
Should the burners go off accidentally in models with valves, a safety
device will trip after approximately 20 seconds to block the outflow of gas
even if the gas tap valve is open.
7.2 Tips on using the burners
For better burner performance and minimum gas
consumption, flat bottomed, even recipients must
be used, with covers and proportional in size to
the burners (see paragraph “7.3 Diameter of
containers ”).
To avoid overcooking or damage to the surface
top while cooking, all recipients or griddles must
be positioned within the cooktop perimeter and
must be at a minimum distance of 3-4 cm (1-1.6
in) from the knobs.

8. CLEANING AND MAINTENANCE
NEVER USE A STEAM JET TO CLEAN THE APPLIANCE.
Before any intervention, disconnect the power supply to the device.
8.1 Cleaning
After it has cooled, clean the cooktop regularly every time it is used.
8.1.1 Regular daily cleaning of the cooktop
In order to clean and preserve the surface, only use specific products
that do not contain abrasive substances or chlorine-based acid
substances.
How to use: pour the product onto a damp cloth and wipe the surface,
then rinse thoroughly and dry with a soft cloth or deerskin.
8.1.2 Food stains or residues
Do not use metallic scouring pads or sharp scrapers: they will
damage the surface.
Use normal non-abrasive products and remove spots or
residues with non-scratch sponges or, if need be, with wood or
plastic utensils.
Rinse thoroughly and dry with a soft cloth or deerskin.
8.2 Cleaning of cooktop components
Grates, burner caps, burner rings and burners can
be removed for easier cleaning. Wash them in
warm water using a non-abrasive detergent, taking
care to remove all tough spots. Before remounting,
allow the components to fully dry.
CAUTION: do not wash these components in a dishwasher.
Under normal use of the cooktop, the stainless steel burner caps and
grates tend to be burnished by the high temperature. Clean these parts
using very fine abrasive sponges or similar commercially available
products. Then use a specific paste polish to restore the steel’s shine.
Your locally authorised after-sales technician is able to supply
professional products for appliance cleaning and care.
8.2.1 Ignition plugs and safety devices
Keep the lighting ignition plugs and safety devices very clean to maintain
them in good working order.
Check them frequently and if necessary clean them with a wet cloth.
