4. Assemble upper bracket to lower bracket so
that the underside of bracket is dimension 'C'
+ 3mm above floor level. (See Fig. 1b)
Reposition appliance and check that top
bracket engages into appliance back as
shown in Fig. 1b.
Pressure testing
1. The oven injector is used as a pressure test
point. Remove the oven furniture.
Remove oven burner box retaining clips (one
spring clip from each side) and remove box
front cover. Replace one clip back into the
right hand side of the burner box.
Remove oven burner by removing the spring
clip from the right hand side of the oven
burner and slide burner off injector, whilst
easing it forward and taking care not to strain
the F.S.D. phial.
2. Connect the pressure gauge to the oven
injector.
3. Check the supply pressure by turning the
thermostat on and one hotplate tap full on
and light the appropriate burner.
The pressure should be either: -
(i) For Natural Gas 20mbar
(ii) For LP. Gas. The pressure must be set to
28 mbar for use on butane or 37 mbar for
use on propane.
4. Turn off the taps, disconnect the pressure
gauge and replace oven burner and cover,
ensuring that the F.S.D phial is correctly
located into the bracket on the burner.
5. Check operation of the oven.
Checking the grill
• Place the grill pan containing the grid, with
the handle attached, into the grill
compartment. Light the grill burner by turning
the grill tap full on and pressing the ignition
button on the fascia panel. As soon as the
burner is lit the button can be released.
Checking the hotplate
• Lift the lid. Fit the burner crowns and caps
ensuring that they are correctly seated. Fit
the pan supports.
• Check each of the hotplate burners in turn by
turning the hotplate tap to its full on position
and pressing the ignition button. As soon as
the burners are lit the button can be
released.
Checking the second oven
1. Turn the second oven thermostat control
knob to Mk.1 and press the ignition button.
As soon as the burner is alight the button
can be released.
2. When the oven burner lights up there should
be a low gas rate at first to the oven burner,
which is the F.S.D. bypass rate.
3. When the F.S.D. phial has heated up it
opens the F.S.D. valve and the main gas
stream flows to the burner.
4. After 1 minute check that the flame covers
the full width of the burner and is stable.
5. Set the oven control to Mk. 2, close the oven
door and check that after about 10 minutes
the flame size has reduced.
6. Turn off the control knob and check that the
oven flames go out.
Checking the main oven
1. Turn on the oven thermostat control knob to
mark 9. As soon as the burner is alight the
control can be released.
2. There should now be a low gas rate to the
burner, which is the F.S.D bypass rate.
3. When the F.S.D. phial has heated up it
opens the F.S.D valve, which allows the
main gas supply to the oven burner.
4. After 1 minute check that the flame covers
the full width of the burner and is stable.
