HOB BURNERS CONTROL KNOBS
The hob burners control knobs are situated on the hob
right hand side. The s mbols on the knobs mean that :
l there is no gas suppl
there is maximum gas suppl
there is minimum gas suppl
LIGHTING THE BURNERS
 For easier lighting, proceed before putting a pan
on the pan support.
To light a burner, turn the relevant knob anticlockwise to
maximum position and push down the knob to ignite.
After lighting the flame, keep the knob pushed down for
about 5 seconds. This will allow the "thermocouple"
(Fig. 1 lett. D) to be heated and the safet device to be
switched off, otherwise the gas suppl would be
interrupted.
Then, check the flame is regular and adjust it as required.
If ou cannot light the flame even after several attempts,
check the "cap" (Fig. 1 lett. A) and the "crown" (Fig. 1 lett.
B) are in the correct position.
To put the flame out, turn the knob to the s mbol l.
 Always turn the flame down or put it out before
taking the pans off the burner.
USING THE HOB CORRECTLY
To ensure maximum burner efficienc , it is strongl
recommended that ou use onl pots and pans with a
bottom fitting the size of the burner used, so that flame
will not spread be ond the bottom of the vessel (see the
table beside).
It is also advisable, as soon as a liquid starts boiling, to
turn down the flame so that it will barel keep the liquid
simmering.
 Use only pans or pots with flat bottom.
Carefull supervise cookings with fats or oil,
since these t pes of foodstuff can result in a fire,
if over-heated.
