USING THE GAS COOKTOPS
GAS BURNERS
Gas flow to the burners are adjusted by turning the knobs(illustrated in (fig.2.1)
which control the valves.
Turning the knob so that the indicator line points to the symbols printed on the
panel achieves to following functions:
=closed valve
=maximum rate
=minimum rate
The maximum aperture position permits rapid boiling of liquids whereas the minimum
aperture position allows slimming or warming of food and maintaining boiling conditions
of liquids.
To reduce the gas flow to minimum, rotate the knob further anti-clockwise to point the
indicator towards the OFF position.
Other operating adjustments can be achieved by positioning the indicator between the
maximum and minimum aperture positions and never between the maximum aperture
and OFF positions.
N.B. When the cooktops is not being used, set the gas knobs to their OFF positions and
also close the gas shut-off valve placed on the main gas supply line.
LIGHTING GAS BURNERS
In order to light the burner, you must:
1- turn the knob in an anti-clockwise direction up to the
position (maximum
rate), push in and hold the knob until the flame has been lit (fig.2.2).
If after 15 seconds the burner has not lit, stop operating the device and open the
compartment door and /or wait at least 1 min before attempting a further ignition
of the burner.
In the event of the burner flames being accidentally extinguished, turn off the burner
control and do not attempt to re-ignite the burner for at least 1 min
2- Adjust the gas valve to the desired position.
To re-light the burner, return the knob to the OFF position and repeat the
operations for lighting.
CHOICE OF BURNER(fig.2.4)
The symbols printed on the panel beside the gas knobs (see fig.2.3)
indicate the correspondence between the knob and the burner.
The most suitable burner is to be chosen according to the diameter and
volume capacity of the container to be warmed.
It is important that the diameter of the pots or pans suitably match the heating
potential of the burners in order not to jeopardize the efficiency of the burners,
bring about a waste of gas fuel.
A small diameter pot or pan placed on a large burner does not necessarily mean
that boiling conditions are reached quicker.
This instruction is based on safety considerations.
Caution!
The cooktops becomes very hot during operation. Keep children well out of reach.
