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.
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
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.
The pressure reading should be nominally
20mbar and must be between 17 mbar and
25mbar.
Turn off the burner supplies.

Conversion from Natural Gas to LPG
It is important to note that this model is designed for
use with natural gas but can be converted for use with
butane or propane gas providing the correct injectors
are fitted. The gas rate is adjusted to suit.
Method
Ensure that the gas taps are in the 'OFF' position
Isolate the hob from the electrical supply
Remove all pan supports, burner caps, rings,
crowns and control knobs.
With the aid of a 7mm box spanner the burner
injectors can then be unscrewed and replaced by
the appropriate LPG injectors.
To adjust the gas rate
With the aid of a thin bladed screwdriver completely
tighten down the by pass adjustment screw. Upon
completion affix the replacement rating plate on the
under side of the hob.
IMPORTANT
The replacement/conversion of the gas hob should
only be undertaken by a competent person.
