DURING OPERATION
•
•
YOU OBSERVE THAT
WHAT SHOULD YOU DO:
•
Lighting the burners:
There is no spark when you
press on the knobs or button.
•
When you press on a knob,
there are sparks on all of the
burners simultaneously.
•
There are sparks, but the
burner (burners) does (do) not
light.
•
If the hob has a gas safety:
during lighting, the flames light,
then go out as soon as the knob
is released
•
In reduced heat mode, the
burner goes out or the flames
remain high.
•
The flames look irregular or
uneven.
•
During cooking, the knobs
become hot.
. Check the electrical connection of your appliance
. Check that the spark plugs are clean
. Check that the burners are clean and properly
assembled
. If the hob is attached to the work top, check that the
mounting brackets are not deformed.
. Check that the gaskets under the knobs are not coming
out of their lodging.
This is normal. The lighting function is centralised and
controls all of the burners simultaneously.
. Check that the gas inlet pipe is not pinched.
. Check that the length of the gas inlet pipe is less than
two meters.
. Check that the gas inlet pipe is open.
. If you have gas in a cylinder or tank, check that it is not
empty.
. If you have just installed the hob or changed the gas
cylinder, hold the knob down in maximum open position
until gas arrives in the burners.
. Check that the injector is not clogged; if it is, unclog it
with a safety pin.
. Press firmly down on the knobs and hold them down for
a few seconds after the appearance of flames.
. Check that the parts of the burner are correctly
mounted.
. Check that the gaskets under the knobs are not coming
out of their lodging.
. Avoid strong draughts in the room.
. Light your burner before placing your saucepan on it.
. Avoid strong draughts in the room.
. Check that the gas type being used corresponds to the
injectors installed (Read about markings on the injectors
in the "Changing the Gas Supply" chapter).
Reminder: The cooking hobs are sold pre-set for use with
network gas (natural gas).
. Check that the burner power screws are properly set
(See the "Changing the Gas Supply" chapter).
. Check the cleanliness of the burners and injectors under
the burners, the assembly of the burners, etc.
