INSTALLATION
Check the appliance is electrically safe and gas sound when you have nished.
Gas Connection
This must be in accordance with the relevant standards.
The exible hose (not supplied with the cooker) must be
in accordance with the relevant standards. Hoses may be
purchased at most builders’ merchants.
The gas supply needs to terminate with a down-facing
bayonet.
The connector is located just below the hotplate level at the
rear of the cooker. If in doubt contact your supplier.
The rear cover boxes limit the position of the supply point.
Because the height of the cooker can be adjusted and
each connection is dierent, it is dicult to give precise
dimensions.
Although a 900 mm hose can be used, a 1250 mm hose
will allow slightly more exibility in the positioning of the
bayonet and make moving the cooker easier.
The hose should be tted so that both inlet and outlet
connections are vertical so that the hose hangs downwards in
a ‘U’ shape.
Ideally the hose supply connection should be within the
shaded area (Fig.7-13).
For Natural Gas, the exible hose must be in accordance with
BS 669. For LP Gas, it should be capable of 50 mbar 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.
After completing the gas connection, make sure that the
cooker is gas sound with a pressure test.When checking for
gas leaks do not use washing up liquid – this can corrode. Use
a product specically manufactured for leak detection.
Natural Gas
The adjustable spring loaded gas pressure regulator is preset
to give a nominal pressure of 1 kPa on Natural gas. Connect to
the Rp½ inlet on the underside of the pressure regulator.
Propane
This cooker is supplied ready for use on Natural gas. A
conversion kit for Propane gas is supplied with the cooker –
see the ‘Conversion to Propane Gas’ section.
Pressure Testing
The pressure test point is accessible on the inlet pipe at the
rear. Remove the test nipple screw and t a pressure gauge to
the test point. Turn on and light two of the hotplate burners.
For Natural Gas cookers the pressure should be between
0.95kPa and 1.0kPa.
For Propane X cookers the pressure should be 2.54 kPa.
