Operation
Hob Burners
To light a burner:
F
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.
Fig. 1
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).

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.
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 Service Centre.
Using the Wok Stand
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 double 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.
FO 2237
Pan Supports
To keep the pan supports in the correct position, they
are hooked into hinges at the back of the hob.
Fig. 2
Model ZGF 681 IX: The pan supports can be lifted
for easier cleaning, as shown in Fig. 2.
Model ZGF 681 ICX: The hob has two cast iron
pan supports.
YES
Take care when removing them. They are
heavy and could damage the hob or your
kitchen furniture if you let them fall.
Never turn the pan supports on the hinges, this
could damage them.
To remove the pan supports completely, proceed
as shown in Fig. 3.
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.
NO
After cleaning, be sure to wipe dry with a soft cloth.
The Burners
The burner caps and crowns (Fig. 1) 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.
Fig. 3
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.
