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 Zanussi Service Force Centre.
Maintenance and Cleaning
Before any maintenance or cleaning can be carried
out, you must DISCONNECT the hob from the
electricity supply.

Cast Iron Pan Supports
The hob has cast iron pan supports.
Take care when removing them. They are very 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. 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.
NO
After cleaning, be sure to wipe dry with a soft cloth.
Ignition electrode
The electric ignition is obtained through a ceramic
"electrode" and a metal electrode (Fig. 1 - letter C). Keep
these components very clean, to avoid lighting difficulties,
and check that the burner crown holes are not
obstructed.
Something Not Working?
If the hob is not working correctly, please carry out the following checks before contacting your local Zanussi Service
Force Centre.

competent person.
The manufacturer will not accept liability, should
the above instructions or any of the other safety
instructions incorporated in this book be ignored.
WHEN THE HOB IS FIRST INSTALLED
Once the hob has been installed, it is important to
remove any protective materials, which were put
on in the factory.
On the end of the shaft, which includes the G 1/2"
threaded elbow, adjustment is fixed so that the washer
is fitted between the components as shown in the
diagram. Screw the parts together without using
excessive force.
FO 0264
Gas Connection
Connection to the gas supply should be with either rigid
or semi-rigid pipe, i.e. steel or copper.
The connection should be suitable for connecting to R
1/2" (1/2 BSP male thread).
A) End of shaft with nut
B) Washer
C) Elbow
It is important to install the elbow correctly, with
the shoulder on the end of the thread, fitted to the
hob connecting pipe.
Failure to ensure the correct assembly will cause
leakage of gas.
When the final connection has been made, it is essential
that a thorough leak test is carried out on the hob and
installation. Ensure that the main connection pipe does
not exert any strain on the hob.
