Conversion from Natural to LPG Gas

IMPORTANT

The replacement/conversion of the appliance should only be undertaken by a registered engineer or competent person.

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.

The oven burner and the hob burners do not need any primary air regulation.

Replacement of gas hob burner nozzles

Ensure that the gas taps are in the 'OFF' position

Isolate the appliance from the electricity 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 (see Technical Data).

Minimum level adjustment of gas hob burners

With the aid of a thin bladed screwdriver completely tighten down the by pass adjustment screw. Upon completion, stick the replacement gas type label on the back plate of the appliance.
