How to use the hob burners
Hob burners
Each hob burner is controlled by a
separate gas tap operated by a control
knob (fig. 5) which has 3 positions marked
on the control panel, these are:
– Symbol ●: tap closed (burner off)
– Symbol : High (maximum)
– Symbol : Low (minimum)
Push in and turn the knob anti-clockwise
to the selected position.
Lighting of the hob burners
To ignite the burner, the following instructions are to be followed:
1) Lightly press and turn the knob anti-clockwise, and position the knob indicator to the
symbol printed on the control panel (fig. 5).
2) Press the knob to operate the electric ignition; or, in the case of a mains failure light the
burner with a match or lighted taper.
3) Adjust the burner according to the setting required.
Low High
To turn the burner off, fully rotate the knob clockwise to the off position: ●.
The maximum setting of the control tap is for boiling, the minimum setting is for slow
cooking and simmering.
All working positions must be choosen between the maximum and minimum setting, never
between the maximum setting and the “OFF” position.
Fig. 5
Electric ignition
The sparks generated by the electrodes close to the burners will ignite the choosen
burner. Whenever the lighting of the burners is difficult due to peculiar conditions of
the gas features or supply, it is advised to repeat the ignition with the knob on
“minimum” position.
Burners Pan diameter
Auxiliary 12 ÷ 14 cm
Semi-rapid 16 ÷ 24 cm
Rapid 24 ÷ 24 cm
Triple-ring 26 ÷ 28 cm
do not use pans with concave or convex bases

Fig. 6a
Choice of burner
The burner must be choosen according to the diameter of the pans and energy required.
Saucepans with handles which are excessively heavy, in relationship to the weight of the
pan, are safer as they are less likely to tip.
Pans which are positioned centrally on burners are more stable than those which are offset.
It is far safer to position the pan handles in such a way that they cannot be accidentally
knocked.
When deep fat frying fill the pan only one third full of oil.
DO NOT cover the pan with a lid and DO NOT leave the pan unattended.
In the unfortunate event of a fire, leave the pan where it is and turn off all controls.
Place a damp cloth or correct fitting lid over the pan to smother the flames.
DO NOT use water on the fire.
Leave the pan to cool for at least 30 minutes.

To use the WOK you need to place the proper stand in order to avoid any faulty
operation of the triple-ring burner (Fig. 7a - 7b).
