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:

1) Re-ignite the burner and set to MIN.

2) Remove the control knob.

3) To adjust, use a thin bladed

screwdriver and turn the
adjustment screw (see diagram)
until the flame is steady and does
not extinguish, when the knob is
turned from MIN to MAX. Repeat
this procedure for all burners.

Pressure testing

The pressure testing must be carried out on
the burners.

Proceed as follows:

1) Remove the pan supports and the

burner caps and crowns.

2) Fit manometer tube over the

injector.

3) Turn on the burner gas supply and

ignite another burner supply.
The pressure reading should be
nominally 20 mbar and must be
between 17 mbar and 25 mbar.

4) Turn off the burner supplies.
