SETTING OF THE GAS BURNERS
When the jets have been changed it is necessary to set the correct air gap by keeping
to the setting "X" as shown in the table " gas consumption" fig 7. Warning the value of '
X ' setting varies in relation to the size of gas burner and type of gas chosen.
A good flame must be of medium length (fig.8B), excessive air will cause the flame to
be short and with sharp colour (fig.8C): in this case it is necessary to extend out the tu-
be for the air setting from the burner body, if there is insufficient air the flame will ap-
pear weak and long (fig. 8A): in this case push the tube of the air setting back into the
burner body. To adjust the air setting tube loosen the retaining screw.
Once the air is correctly set secure the screw over the tube ( fig. 7).

REGULATING THE MINIMUM FLAME
After lighting the burners, turn the control knob to the minimum setting and then remo-
ve the knob (this can easily be removed by apply a gentle pressure).
Using a small «Terminal» type screwdriver the regulating screw can be adjusted as in
Fig. 9. Turning the screw clockwise reduces the gas flow, whilst turning it anticlockwise
increases the flow – Use this adjustment to obtain a flame of approximately 3 to 4 mm
in length and then replace the control knob.
When the gas supply available is LPG (Bottle gas)- the screw to set the idle flame must
be turned (clockwise) to the end stop.

This appliance must only be used for the purpose for which it is intended, domestic
cooking, and any other use will be considered improper and could therefore be danger-
ous. The Manufacturer will not be responisble for any damage or loss resulting from
improper use.
USING THE GAS BURNER
To ignite the burners, place a lighted taper close to the burner, press in and turn the
control knob anti-clockwise.
If the burners have not been used for a couple of days, wait for a few seconds before
lighting the burner, this will allow any air present in the pipes to escape.
For appliances fitted with electronic ignition carry out the following:
• push in and turn the knob anticlockwise to the
• ignite the burner by pressing the sparker button.
For hobs fitted with automatic ignition simply push in and turn the knob to the sym-
bol.
The ignition system will continue to generate sparks as long as the gas tap is being
pressed.
If the burner is not ignited within 5 seconds, turn the knob to the 0 position and repeat
the operation.
For models fitted with a safety tap (which cuts-off the flow of gas if the flame is acci-
dentally extinguished) the burners are ignited ad described above, but care must be
taken to keep the knob pressed in for 5 or 6 seconds after the flame is ignited.

ATTENTION: Prior to switching on the gas hob ensure that the burners and bur-
ner caps are correctly placed within their position.
GENERAL ADVICE
For the best results, the flat-bottomed pans size should match the gas burner size as
follows. See fig. 1 pag. 31.
— Front right burner
— Front left burner
— Back right burner
— Back left burner
For smaller containers the gas burner should be regulated so that the flame does not
overlap the base of the pan. Vessels with concave or convex base should not be used.
WARNING: If a burner is accidentally extinguehed, turn the knob to the off posi-
tion and do not attempt to re-ignite if for at least 1 minute.
To protect the glass lid from damage and in the interests of safety, the burners/plates
must be turned off and the burner/pan support/plate area must be cool before closing
the lid down.
