ArtNo.110-0011 110 DF gas hose connections
Because the height of the cooker can be adjusted and
each connection is different, it is difficult to give precise
dimensions.
Although a 900 mm hose can be used, a 1250 mm hose
All dimensions in millimetres
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 in
a 'U' shape.
Ideally the hose supply connection should be within the
shaded area 'A' (Fig. 7.11).
For Natural Gas, the flexible 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.
Pressure Testing
The gas pressure can be measured at one of the hotplate
burner injectors (not a wok burner).
Lift off a burner head. Fit the pressure gauge to the injector.
Turn on and light one of the other hotplate burners.
Turn on the control knob for the 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 the
burner top in the correct way on the burner body.
