Fitting the splash back
The cooker can be installed with or without the supplied
splashback. To fit splash remove the two fixing screws (3mm
hexagonal socket head) and nuts that pass through the top
of the rear flue grille. Hold the splash back in position. From
the rear refit the 2 fixing screws and nuts.
Fitting a stability bracket
A stability bracket or chain (not supplied by with the
cooker) should be fitted when the cooker is connected to a
flexible gas supply.
When fitting a stability bracket read these instructions
together with the leaflet supplied with the bracket.
1. Place the cooker in its intended position and level the
cooker.
2. Draw a pencil line 100mm from the front edge of the
levelling feet.
3. Mark the centre line for the bracket by measuring
550mm from the left hand side of the cooker.
4. Lower the front roller and move the cooker forward.
5. Measure back from the pencil line 550mm to locate the
front edge of the bracket. Fix the bracket to the floor.
6. Measure the height from floor level to engagement
edge in back of cooker. Add 3mm to this dimension and
assemble the stability bracket to this height. (i.e. from
floor level to underside of the top member) and ensure
the bracket does not foul the oven burner assembly.
Gas Connection
The Gas supply needs to terminate with a down facing
bayonet. The rear cover boxes limit the position of the
supply point.

Because the height of the cooker can be adjusted and
each connection is different it is difficult to give precise
dimensions. Ideally the house supply bayonet should be in
the shaded area shown in the diagram. 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 fl exible 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 burners). Lift off a
burner head. Fit the pressure gauge to the injector. Turn on
the hotplate burner and turn on and light one of the other
hotplate burners.
For Natural Gas cookers the pressure should be 20mbar.
For LP Gas cookers the pressure should be 29mbar for
Butane
37mbar for Propane.
Reassemble burner top, making sure it is reassembled in the
correct way on the burner body.
