Cast Iron
:
usable, but not recommended. Poor performance.
May scratch the surface.
Copper Bottom /
stoneware:
heavy weight recommended. Good
performance, but copper may leave residues which can appear
as scratches. The residues can be removed, as long as the hob
is cleaned immediately. However, do not let these pots boil
dry. Overheated metal can bond to glass hobs. An overheated
copper pot will leave a residue that will permanently stain the hob.
Porcelain/enamel : Good perfomance only with a thiny smooth,
flat base.
Glass-ceramic
:
not recommended. Poor performance. May
scratch the surface.
7 • HOW TO OPERATE THE GLASS CERAMIC
HOB
•
Locate the sign corresponding to the cooking zone that you need
:
Each surface unit is regulated by a control knob which provides
access to any power levels.
•
It is recommended that heat setting is at its highest until it has
properly warmed up and then lower to the desired cooking setting.
•
The residual heat indicator lights up when the heat zone
temperature reaches 60°C and above. It will stay on, even if the
unit is switched off, until the surface has cooled down. It will
switch off when the temperature of the heat zone falls below 60°C.
•
To switch off an heat zone, turn the corresponding knob back
on the "0" setting.
•
Positions
:
the examples below are intended as a guide. When
you become familiar with using your hob you will be able to work
out the settings which suit you best.
1-2 Very low
To keep a dish hot, melt butter and chocolate...
3-4 Low
Slow coocking, sauces, stews, rice pudding, poached eggs...
5-6 Moderately
Beans, frozen foods, fruit, boiling water...
7-8
Medium
Steamed apples, fresh vegetables, pasta, crepes, fish...
9-10 High
More intense coocking, omelettes, steaks...
11-12 Very high
Steaks, chops, frying...

Some tips....
9. PROBLEM SOLVING
The cooking zones do not simmer or only fry gently
•
Only use flat-bottomed pans. If light is visible between the pan
and the hob, the zone is not transmitting heat correctly.
•
The pan bottom should fully cover the diameter of the selected
zone.
The cooking is too slow
•
Unsuitable pans are being used. Only use flatbottomed
utensils, that are heavy and have a diameter at least the same
as the cooking zone.
Small scratches or abrasions on the hob’s glass surface
•
Incorrect cleaning or rough-bottomed pans are used; particles
like grains of sand or salt get between the hob and the bottom
of the pan. Refer to the “CLEANING” section; make sure that
pan bottoms are clean before use and only use smooth bottomed
pans. Scratches can be lessened only the cleaning is done
correctly.
Metal marks
•
Do not slide aluminium pans on the hob. Refer to the cleaning
recommendations.
•
You use the correct materials, but the stains persist.
Use a razor blade and follow the “CLEANING” section.
Dark stains
•
Use a razor blade and follow the “CLEANING” section.
Light surfaces on the hob
•
Marks from an aluminium or copper pan, but also mineral, water
or food deposits; they can be removed using the cream cleaner.
NB:
Do not use a sponge which is too wet.
Never use a knife or a screwdriver.
A scraper with a razor blade will not damage the surface,
as long as it is kept at an angle of 30°.
Never leave a scraper with a razor blade within the reach
of children.
Never use abrasive products or scouring powders.
•
The metal surround
:
to safely clean the metal surround wash
with soap and water, rinse, then dry with a soft cloth.
•
The control knobs
:
can be removed by pulling them upwards.
Only clean with soapy water and dry well before placing them. Be
careful not to let any water get into the holes and take care when
replaced the control knobs.
30° Maxi
•
Before carrying out any maintenance work on the hob, allow it
to cool down.
•
Only products, (creams and scrapers) specifically designed for
glass ceramic surfaces should be used. They are obtainable
from hardware stores.
•
Avoid spillages, as anything which falls on to the hob surface
will quickly burn and will make cleaning more difficult.
•
It is advisable to keep away from the hob all substances which
are liable to melt, such as plastic items, sugar, or sugar-based
products.
MAINTENANCE:
- Place a few drops of the specialised cleaning product on the
hob surface.
- Rub any stubborn stains with a soft cloth or with slightly damp
kitchen paper.
- Wipe with a soft cloth or dry kitchen paper until the surface is
clean.
If there are still some stubborn stains:
- Place a few more drops of specialised cleaning fluid on the
surface.
- Scrape with a scraper, holding it at an angle of 30° to the hob,
until the stains disappear.
- Wipe with a soft cloth or dry kitchen paper until the surface is
clean.
- Repeat the operation if necessary.
A
FEW HINTS:
Frequent cleaning leaves a protective layer which is essential to
prevent scratches and wear. Make sure that the surface is clean
before using the hob again. To remove marks left by water, use
a few drops of white vinegar or lemon juice. Then wipe with
absorbent paper and a few drops of specialised cleaning fluid.
The control knobs can be removed for a complete cleaning.
However, you must care not to let any liquid go into the open
zones, and then to push the knobs fully on fitting back.
The glass ceramic surface will withstand scraping from flat-
bottomed cooking vessels, however, it is always better to lift them
when moving them from one zone to another.
