Conversion from Natural to LPG Gas
IMPORTANT
The replacement/conversion of the gas hob should
only be undertaken by a CORGI registered engineer.
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 undo the by
pass screw about 1/4 of a turn (45°). Upon completion
stick the replacement rating plate near the gas supply
pipe.
Replacement of gas oven
burner nozzle

c) with a socket spanner 7 unscrew and remove the
nozzle, situated in the bottom of the oven, and replace
it with the proper one (see Technical data);
d) reassemble the burner following the same procedure
backwards.
Minimum level adjustment
of gas oven burner
After setting the oven on maximum temperature with door
closed for about 10 minutes, turn the knob on minimum.
To reach the thermostat by-pass screw and adjust the
minimum level, act as follows:
– take out the knobs;
– remove the front panel;
– in case of conversion from natural gas to LPG, tightly
screw the by-pass screw of thermostat (see fig.);
– to convert from LPG to natural gas, unscrew the by-
pass screw, until a regular small flame is reached.
– finally check that turning quickly the tap from
maximum position to minimum position, the flame
does not go out;
– reassemble the front panel and the knobs.
The oven burner does not need any primary air regulation. FO 1061
