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.
You can find two different adjustment screw
locations according to the gas tap (see
diagram). The "b" type has the adjustment
screw located down the centre of the gas tap
control shaft. The "c" type has the by pass
screw located to the side of the gas tap
itself.
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 procedure for all burners.
Pressure Testing
Remove left hand pan support and front left
burner cap and crown.
Fit manometer tube over the injector.
Turn on the burner gas supply and ignite
another burner supply.
The pressure reading should be nominally
20mbar and must be between 17 mbar and
25mbar.
