When the hob has been fully installed it will be necessary

to check the minimum flame setting. To do this, follow

the procedure below.

- Turn the gas tap to the MAX position and ignite.

- 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.

The adjustment screw is located down the

centre of the gas tap control shaft or on the

lower right hand side of the shaft (see diagram).

To adjust, use a thin bladed screwdriver and

turn the adjustment screw until the flame is

steady and does not extinguish, when the knob

is turned from MIN to MAX. Repeat this proce-

dure for all burners.
