26INSTALLATION Check the appliance is electrically safe and gas sound when you have finished.LevellingYou are recommended to use a spirit level on a shelf in one ofthe ovens to check for level. Place the cooker in its intendedposition taking care not to twist it within the gap betweenthe kitchen units as damage may occur to the cooker or theunits. The front feet and rear rollers can be adjusted to levelthe cooker.To adjust the height of the rear of the cooker, use a 13 mmspanner or socket wrench to turn the adjusting nuts at thefront bottom corners of the cooker.To set the front turn the feet bases to raise or lower.Gas ConnectionThis must be in accordance with the relevant standards.The flexible hose (not supplied with the cooker) must bein accordance with the relevant standards. Hoses may bepurchased at most builders’ merchants.We recommend that a Micropoint gas hose is used wheninstalling this appliance.The gas supply needs to terminate with a down facingbayonet (Fig. 8.11).The connector is located just below the hotplate level at therear 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 andeach connection is different, it is difficult to give precisedimensions.Although a 900 mm hose can be used, a 1100 mm hosewill allow slightly more flexibility in the positioning of thebayonet and make moving the cooker easier.The hose should be fitted so that both inlet and outletconnections are vertical so that the hose hangs downwardsin a ‘U’ shape. Ideally the hose supply connection should bewithin the shaded area ‘A’ (Fig. 8.12).For Natural Gas, the flexible hose must be in accordance withBS 669. For LP Gas, it should be capable of 50 mbar pressureand 70 °C temperature rise. If in doubt contact, your supplier.Screw connect the threaded end of the hose into the gasinlet. After completing the gas connection, make sure thatthe cooker is gas sound with a pressure test.Pressure TestingThe gas pressure can be measured at one of the hotplateburner injectors (not the wok burner). Lift off a burner head.Fit the pressure gauge to the injector. Turn on and light oneof the other hotplate burners. Turn on the control knob forthe burner with the pressure gauge fitted to let gas through.See the data badge for test pressures.Turn off the burners. Make sure that you reassemble theburner top in the correct way on the burner body.Fig. 8.11Fig. 8.12Flexible hosePipework PipeworkFlexible hose470350675A315All dimensions in millimetresGas inlet
