Operation
Hob burners
F
To light a burner:
l push in the relevant control knob and turn it
anticlockwise to maximum position;
l upon ignition, keep the knob pushed down about 5
seconds. This will allow the "thermocouple" (Fig. 1 -
letter D) to be heated and the safety device to be
switched off, otherwise the gas supply would be
interrupted.
l then adjust the flame as required.
If the burner does not ignite, turn the control knob to
zero, and try again.
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 on the right).
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.
Take care when frying food in hot oil or fat, as
the overheated splashes could easily ignite.
As soon as a liquid starts boiling, turn down the
flame so that it will barely keep the liquid simmering.
If the control knobs become difficult to turn, please
contact your local Service Force Centre.

The Hob Broiler (mod. ZGF 991)
The appliance is supplied with an electric broiler situated
in the central zone of the hob.
To switch on the broiler, turn the relevant control knob to
the required heat setting. The control knob is numbered
0 (OFF) - 8 (Maximum).
The broiler may smoke a little and produce a
slightly unpleasant odour when used for the first
time. This is quite normal and will disappear after
a few minutes.
Preheat the broiler on a full setting for 15 minutes, then
adjust the heat setting as desired.

intended as a guide only. It may be necessary to increase
or decrease the temperatures to suit individual
preferences and requirements. When cooking fat foods
(bacon, sausages, etc.) it is recommended to use
intermediate settings in order to avoid smoke.After
switching off the broiler, especially after long cooking
sessions, its front part will remain hot for at least 45
minutes. Always use oven gloves to remove and replace
food on the broiler.

Using the Wok Stand (mod. ZGF 981)
A wok stand is provided to enable you to use a round
bottomed wok on the hob. The wok stand must only be
used on the triple crown burner, and should not be used
with any other type of wok or pan.
When fitting the wok stand, ensure the recesses in the
frame fit securely onto the bars of the pan supports, as
shown in the diagram.
Maintenance and Cleaning
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 washing 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.
The Burners
The burner caps and crowns can be removed for cleaning.
Wash the burner 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.
Ignition candle
The electric ignition is obtained through a ceramic
"candle" and a metal electrode (Fig. 1 - letter C). Keep
these components well clean, to avoid difficult lighting,
and check that the burner crown holes are not
obstructed.
The electric broiler (mod. ZGF 991)
Always clean the hob broiler after it has cooled down
using a soft cloth well wrung out in warm water.
Dry the broiler before using it. From time to time it will be
necessary to oil the broiler when it is still warm, using a
little vaseline or food oil.
Important! For the proper functioning of the broiler, refit
its screen (as shown in the relevant diagramm).

Page 6
Wok Stand (mod. ZGF 981)
The Wok Stand is dishwasher proof. If washing it by hand,
take care when drying it as the enamelling process
occasionally leaves rough edges. If necessay, remove
stubborn stains using a paste cleaner.
Cast Iron Pan Supports
The hob has cast iron pan supports.
Take care when removing them. They are fair heavy and
could damage the hob or your kitchen furniture if you let
them fall down.
To keep the pan supports in the correct position, they
are hooked into hinges at the back of the hob. When
removing the pan supports, lift them up as shown in the
diagram (Fig. 2). Never turn the pan supports on the
hinges, this could damage them.
Wash the pan supports using hot soapy water. If
necessary, a paste cleaner or a soap impregnated steel
wool pad can be used with caution.
