Operat ion
HOB BURNERS
To light a burner, turn the relevant control knob
anticlockwise to maximum position. At the same time
push the electric ignition button which is marked with
a little spark.. Then adjust the flame as required.
If the burner does not ignite, turn the control knob to
zero, and try again.
When switching on the mains, after
installation or a power cut, it is quite normal
for the spark generator to be activated
automatically.
i
To ensure maximum burner efficiency, you should
only use pots and pans with a flat bottom fitting the
size of the burner used (see table).

Medium (semi-rapid) 120 mm.
Small (Auxiliary) 80 mm.

240 mm.
220 mm.
160 mm.
If you use a saucepan which is smaller than
the recommended size, the flame will spread
beyond the bottom of the vessel, causing the
handle to overheat.
As soon as a liquid starts boiling, turn down
the flame so that it will barely keep the
liquid simmering.
i
Take care when frying food in hot oil or fat,
as the overheated splashes could easily
ignite.
If the control knobs become difficult to turn,
please contact your local Zanussi Service
Centre.

Main t en an ce an d Clean in g
Before any maintenance or cleaning can be
carried out, you must DISCONNECT the
hob from the electricity supply.
The hob is best cleaned whilst it is still warm, as
spillage can be removed more easily than if it is left
to cool.
The Hob Top
Regularly wipe over the hob top using a soft cloth
well wrung out in warm water to which a little
wasing up liquid has been added. Avoid the use of the
following:
- household detergent and bleaches;
- impregnated pads unsuitable for non-stick saucepans;
- steel wool pads;
- bath/sink stain removers.
Should the hob top become heavily soiled, it is
recommended that a cleaning product such as Hob
Brite or Bar Keepers Friend is used.
Pan Supports
The pan supports are dishwasher proof. If washing
them by hand, take care when drying them as the
enamelling process occasionally leaves rough edges.
If necessay, remove stubborn stains using a paste
cleaner.
The Burners
The burner caps and crowns can be removed for
cleaning.
Wash the burners caps and crowns using hot soapy
water, and remove marks with a mild paste cleaner. A
well moistened soap impregnated steel wool pad can
be used with caution, if the marks are particularly
difficult to remove.
After cleaning, be sure to wipe dry with a soft cloth.
