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 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.
IMPORTANT
The replacement/conversion of the gas hob should
only be undertaken by a competent person
Repais may only be carried out by
CORGI registered engineers.
