PROBLEMS & SOLUTIONS
Lighting burners.
There are no sparks when I push
down on the knobs:
o Check that your hob is electrically
connected; check that the igniters are
clean-,
o Check that burners are clean and
properly assembled,
o If the hob is fixed to the worktop,
make sure that the fixing clamps
have not been twisted,
o 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.
o Check that the gas inlet is open,
o If you use gas tanks or cylinders
check that they are not empty.
o 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.
o 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.
o Press the knobs as far as they will
go and maintain the pressure for
several seconds after flames appear.
o Check that the burner components
are correctly positioned.
o Check that the sealing washers
under the knobs have not come out
of their locations.
o Avoid strong draughts in the room.
o Light the burner before placing a
pan on it.
In the low position, the burner
goes out or flames remain too high.
o Void strong draughts in the room.
o 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).
o Check that the retarder screws are
properly adjusted (see "Changing gas
type" paragraph).
The flames have an irregular
appearance.
o Check that
injectors underneath them, burner
assemblies, etc. are clean.

cooking
o Use smaller pans on the burners
close to the knobs. Put large pans on
the larger burners, further away from
the knobs.
o Place the pan in the centre of the
burner. It should not sit over the
knobs.
