Pressure Testing
1. Remove left hand pan support and front left burner cap and crown. 2. Fit manometer tube over the injector. 3. Turn on the burner gas supply and ignite another burner. 4. The pressure reading should be nominally 20mbar and must be between 17 mbar and 25mbar. 5. 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
1. Ensure that the gas taps are in the 'OFF' position 2. Isolate the hob from the electrical supply 3. Remove all pan supports, burner caps, rings, crowns and control knobs. 4. With the aid of a 7mm box spanner the burner injectors can then be unscrewed and replaced by the appropriate LPG injectors (see "Characteristics of gas burners" on the back cover of this book).
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.
