Conversion from Natural Gas to LPG

Method

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

Isolate the hob 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.

TO ADJUST THE GAS RATE

With the aid of a thin bladed screwdriver completely tighten down the by pass adjustment screw, which is located down the centre of the gas tap control shaft.

Upon completion stick the replacement rating plate on the under side of the hob.
