The cooker should be connected to the gas-supplyby a corgi registered installer. During installation of this product it is essential to fit an approved gas tap to isolate the supply from the appliance for the convenience of any subsequent removal or servicing. Connection of the appliance to the gas mains or liquid gas must be carried out according to the prescribed regulation in force, and only after it is ascertained that it is adaptable to the type of gas to be used. If not, follow the instructions indicated in the paragraph headed “Adaptation to different gas types”. On some models the gas supply can be connected on the left or on the right, as necessary; to change the connection, reverse the position of the hose holder with that of the cap and replace the gasket (supplied with the appliance). In the case of connection to liquid gas, by tank, use pressure regulators that conform to the regulation in force. The gas supply must be connected to the left of the appliance. Be sure that the hose does not pass through the rear of the cooker touching hot parts.


600 mm

Important: make sure the supply pressure conforms with the values shown in the table entitled “Caracteristics of the burners and nozzles”.When the cooker is installed between cabinets (recessed), the gas connection must be effected by an approved flexible hose with bayonet fitting (BS 669 Current Edition).The gas inlet for the cookers is a threaded G 1/2 gas female fitting.

Connecting the gas supply

To make the connection, a flexible hose should be used corresponding to the current gas regulations which are:

the hose must never be at any point in its lenght in contact with the “hot” parts of the cooker;

the hose must never be longer than 1,5 metre;

the hose must not be subject to any tension or torsional stress and it must not have any excessively narrow curves or bottlenecks;

the hose must be easy to inspect along its entire length to check its condition;

the hose must always be in good condition, never attempt to repair.

Important: the installation must comply with gas safety (installation and use) regulations 1984. In all cases for the above, by low, a qualified, corgi approved engineer must be called for installation.

Important: Before using the oven, position the oven burner deflector "A" (provided with the appliance) in the correct place by inserting the lower tab into the support slot (see figure).


Disposing of the appliance

When disposing of the appliance please remove the plug by cutting the mains cable as close as possible to the plug body and dispose of it as described above.

Adapting the cooker to different types of gas

In order to adapt the cooker to a different type of gas with respect to the gas for which it was produced (indicated on the label attached to the lid), follow these steps:

a)replace the hose holder mounted on the appliance with that supplied in the bag of “cooker accessories”.

b)Replacing the burner nozzles on the hob:

remove the grids and slide the burners from their housings;

unscrew the nozzles using a 7 mm socket spanner, and replace them with nozzles for the new type of gas (see table 1 “Burner and nozzle characteristics”).


replace all the components by repeating the steps in reverse order.

c) Minimum regulation of the hob burners:

turn the tap to minimum;

remove the knob and adjust the regulation screw, which is positioned in or next to the tap pin, until the flame is small but steady.

N.B.: in the case of liquid gas, the regulation screw must be screwed in to the bottom.

check that the flame does not turn off when you turn the tap quickly from high to low.

d) Regulating the primary air of the burners:

The primary air of the burners requires no regulation.

Adapting to different types of gas

Electrical connection

Power supply voltage and frequency: 220-240Va.c. 50 Hz.

Note: the supply cable must be positioned so that it never reaches at any point a temperature 50°C higher than the room temperature.The cable must be routed away from the rear vents. Should you require it, you may use a longer cable, however, you must ensure that the cable supplied with the appliance is replaced by one of the same specifications in accordance with current standards and legislation.

Your appliance is supplied with a 13 amp fused plug that can be plugged into a 13 amp socket for immediate use. Before using the appliance please read the instructions below.



Replacing the fuse:

When replacing a faulty fuse, a 13 amp ASTA approved fuse to BS 1362 should always be used, and the fuse cover re-fitted.If the fuse cover is lost, the plug must not be used until a replacement is obtained.

Replacement fuse covers:

If a replacement fuse cover is fitted, it must be of the correct colour as indicated by the coloured marking or the colour that is embossed in words on the base of the plug. Replacements can be obtained directly from your nearest Service Depot.

Removing the plug:

If your appliance has a non-rewireablemoulded plug and you should wish to remove it to add a cable extension or tore-routethe mains cable through partitions, units etc., please ensure that either:

the plug is replaced by a fused 13 amp re-wireableplug bearing the BSI mark of approval.


the mains cable is wired directly into a 13 amp cable outlet, controlled by a switch, (in compliance with BS 5733) which is accessible without moving the appliance.

Please note: for appliances with a rating greater than 13 amp (eg: electric hob, double ovens and freestanding electric cookers etc.) the mains cable must be wired into a cooker output point with a rating of 45 amp. In this case the cable is not supplied.

Disposing of the plug:

Ensure that before disposing of the plug itself, you make the pins unusable so that it cannot be accidentally inserted into a socket. Instructions for connecting cable to an alternative plug:

Important: the wires in the mains lead are coloured in accordance with the following code:

Green &Yellow

- Earth


- Neutral


- Live

If the colours of the wires in the mains lead do not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:

Connect Green & Yellow wire to terminal marked “E” or$or coloured Green or Green &Yellow. Connect Brown wire to terminal marked “L” or coloured Red.

Connect Blue wire to terminal marked “N” or coloured Black.

If a 13 amp plug (BS 1363) is used it must be fitted with a 13 amp fuse. A 15 amp plug must be protected by a 15 amp fuse, either in the plug or adaptor or at the distribution board. If you are in any doubt about the electrical supply to your machine, consult a qualified electrician before use.
