Fitting a stability bracket
A stability bracket/chain (not supplied 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 (Fig 7-12).
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
(Fig 7-13).
Gas Connection
Must be in accordance with the relevant standards. A hose is
not supplied by with the cooker. Hoses may be purchased at
most builders' merchants.
The Gas supply needs to terminate with a down facing
bayonet.
Because the height of the cooker can be adjusted and
each connection is different it is difficult to give precise
dimensions. The hose should be fitted so that both inlet
and outlet connections are vertical so that the hose hangs
downwards in a 'U' shape (Fig.7-14).
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.
After completing the gas connection, check the cooker is gas
sound with a pressure test.

Pressure testing

The gas pressure can be measured at pressure test point on
the gas inlet. Turn off the gas supply to the cooker. Fit the
pressure gauge to the pressure test point. Turn on the gas
supply and light one of the hotplate burners.
Turn off the gas supply to the cooker and disconnect pressure
gauge.
