PROBLEMS & SOLUTIONS
• 4
4.1 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.
4.2 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.
4.3 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
• Make sure the cover is properly
positioned (3.1.2).
4.3 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
locations.
• Avoid strong draughts in the room.
• Light the burner before placing a pan
on it.
4.5 IN THE LOW POSITION, THE
BURNER GOES OUT OR FLAMES
REMAIN TOO HIGH.
• Avoid 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).

IRREGULAR APPEARANCE.
• Check that the burners and injectors
underneath them, burner assemblies,
are clean, etc....
4.5 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
burner. It should not sit over the knobs.
