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. 7. 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.

When you have carried out the new gas regulation, replace the old gas rating pla-
te on your appliance with one (supplied with hob) suitable for the type of gas for
which it has been regulated.
