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 (see table on page 12).

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 must only
be undertaken by a competent person, who is CORGI
REGISTERED.
