PROBLEMS & SOLUTIONS
❐
LIGHTING BURNERS.
There are no sparks when I push down
on the knobs:
• Check that your hob is electrically
connected; check that the igniters are
clean,
• Check that burners are clean and
properly assembled,
• If the hob is fixed to the worktop, make
sure that the fixing clamps have not been
twisted,
• Check that the sealing washers under
the knobs have not come out of their
locations.
❐
WHEN I PRESS A KNOB, THERE
ARE SPARKS ON ALL BURNERS AT
ONCE.
This is normal. The lighting system is
centralised and all the burners spark at
the same time.
❐
THERE ARE SPARKS BUT THE
BURNERS DO NOT LIGHT.
• Check that the gas inlet is open,
• If you use gas tanks or cylinders check
that they are not empty.
• If you have just installed your hob or
changed a gas cylinder, keep the knob
fully pressed for a few seconds to allow
gas to arrive at the burners.
• Check that the injector is not blocked
and, if it is, unblock it with a safety pin.
❐
WHEN LIGHTING, FLAMES IGNITE
BUT GO OUT WHEN THE KNOB IS
RELEASED.
• Press the knobs as far as they will go
and maintain the pressure for several
seconds after flames appear.
• Check that the burner components are
correctly positioned.
• Check that the sealing washers under
the knobs have not come out of their lo-
cations.
• Avoid strong draughts in the room.
• Light the burner before placing a pan on it.
❐
IN THE LOW POSITION, THE
BURNER GOES OUT OR FLAMES RE-
MAIN TOO HIGH.
• Void strong draughts in the room.
• Check that the injectors fitted are the
right ones for the gas being used (see the
identification on the injectors in the
"Changing gas type" section).
Reminder: remember that gas hobs are
delivered set up for use with mains gas
(natural gas).
• Check that the retarder screws are
properly adjusted (see "Changing gas
type" paragraph).
❐
THE FLAMES HAVE AN IRREGULAR
APPEARANCE.
Check that the burners and injectors
underneath them, burner assemblies,
etc. are clean.
❐
KNOBS BECOME HOT DURING
COOKING
• Use smaller pans on the burners close
to the knobs. Put large pans on the larger
burners, further away from the knobs.
• Place the pan in the centre of the bur-
ner. It should not sit over the knobs.
