Fitting a stability bracket
A stability bracket or 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.
3. Mark the centre line for the bracket by measuring
450mm from the left hand side of the cooker.
4. Lower front roller and move cooker forward.
5. Measure back from pencil line 550mm to locate
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 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. When checking for
gas leaks do not use washing up liquid - this can
corrode. Use a product specifically manufactured for
leak detection.
Pressure testing
The gas pressure can be measured at the injector of
one of the LH hotplate burners. Remove the pan
support, burner head and caps. The injector is now
accessible.
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.
