Commissioning
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.

Fit manometer tube over the injector.

another burner supply.
