Operation
Hob burners
To light a burner:
F
l push in the relevant control knob and turn it
anticlockwise to maximum position;
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).
Burner minimum maximum
diameter diameter
Ultra-rapid
(Triple-crown) 180 mm. 260 mm.
Large (rapid) 180 mm. 260 mm.
Medium (semi-rapid) 120 mm. 220 mm.
Small (Auxiliary) 80 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.
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.
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.
4
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. 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.
