-Set the gas tap to the MIN flame position then turn the control knob from MIN to MAX several times. If the flame is unstable or is extinguished follow the procedure below.

Procedure:

Re-ignite the burner and set to MIN. Remove the control knob.

You can find two different adjustment screw locations according to the gas tap (sse diagram). The "b" type has the adjustment screw located down the centre of th egas tap control shaft. The "c" type has the by pass screw located to the side of the gas tap itself.
