INSTALLATION

Check the appliance is electrically safe and gas sound when you have finished.

Although a 900mm hose can be used, a 1250mm hose will allow slightly more flexibility in the positioning of the bayonet and make moving the cooker easier. The hose should be fitted so that both inlet and outlet connections are vertical so that the hose hangs downwards.

The connector is located just below the hotplate level at the rear of the cooker.

For Natural Gas the flexible hose must be in accordance with B.S.669.

For LP Gas it should be capable of 50mbar pressure, 70°C temperature rise and carry a red stripe, band or label.

If in doubt contact, your supplier.

Screw connect the threaded end of the hose into the gas inlet in the underside of the connector block on the back of the cooker.

After completing the gas connection, check the cooker is gas sound with a pressure test.

Pressure testing

The gas pressure can be measured at one of the centre hotplate burner injectors (not the Wok burner). Lift off a burner head. Fit the pressure gauge to the injector. Turn on and light one of the other hotplate burners. Turn on the control knob for the burner with the pressure gauge fitted to let gas through.

Turn off the burners. Reassemble burner top, making sure it is reassembled in the correct way on the burner body.

Electrical Connection

This appliance must be installed by a qualified electrician to comply with the relevant Institute of Electrical Engineers (I.E.E.) regulations and also the local electricity supply company requirements.

WARNING: THIS APPLIANCE MUST BE EARTHED

Note

The cooker must be connected to the correct electrical supply as stated on the voltage label on the cooker, through a suitable cooker control unit incorporating a double pole switch having a contact separation of at least 3mm in all poles. This cooker must not be connected to an ordinary domestic power point.

Single phase

Access to the mains terminal is gained by removing the electrical terminal cover on the back panel.

When preparing the electrical supply leads, make sure that the earth wire is longer that the phase or neutral wires. The earth lead should be long enough that it is never under any strain.

Connect the mains cable to the correct terminals for your electrical supply type (see fig.). Check that the links are correctly fitted and that the terminal screws are tight. Secure the mains cable using the cable clamp.

These appliances are of type X with regard to protection against over heating of the surrounding surfaces.

Current Operated Earth Leakage Breakers

Where the installation is protected by a 30 milliamp sensitivity residual current device (RCD), the combined use of your cooker and other domestic appliances may occasionally cause nuisance tripping. In these instances the cooker circuit may need to be protected by fitting 100mA device. This work should be carried out by a qualified electrician.

Hotplate

Check each burner in turn. There is an ignition system that works when the control knob is pressed in. Push in tap and turn to the large flame symbol.

Check that the burner lights correctly.
