pilot igniting and will be fully on. Keep at this position for a further 10 seconds to allow
the pilot flame to stabilise.
3.
Release the button. The button should automatically spring up by approximately
10mm and the centre radiants should remain fully on.
If the flames go out at this
stage or when checking the rest of the setting positions, try the full lighting sequence
again. If the flames fail after two attempts, investigate the pilot unit. If for any reason
the slider control does not spring up, raise the slider to the off (O) position (Topmost
position) and investigate why the slider is not operating correctly.
4.
Slide the button up to the medium (M) setting, you should feel a check to the
button movement at this position. The outer radiants should light on their low setting.
5.
Slide the control button up again to the high (H) setting, you should feel a check to
the button movement at this position. The outer radiants should now be on their high
setting.
6.
Slide the control button up again to off (O) position. Both pilot and all radiants
should go out. While cooling the radiants may make some crackling noises. This is
quite normal.
7.
The control settings are:
8.2 Flame supervision and spillage monitoring system.
This pilot unit includes a system that will automatically shut off the gas supply if the
pilot flame goes out or if there is insufficient oxygen due to spillage or poor ventilation.
Check that the system operates properly as follows:
1.
Light the appliance. Set the slide control to the high (H) position and leave for one
minute.
2.
Set the control to the low (L) position. Isolate the gas supply at the inlet ‘T’
connector. The pilot and main burner will go out.
Note the time when the pilot goes
out
.
Listen for a snap sound at the gas tap.
Note the time when the sound is
heard
.
This sound is caused by an electromagnetic valve shutting off the gas supply
through the tap. The valve is located in the body of the tap. The valve should operate
within 60 seconds of the pilot going out
.
If the valve does not operate within this
time limit do not allow the appliance to be used until the fault has been corrected.
This monitoring system must not be adjusted, bypassed or put out of
operation.
This monitoring system, or any of its parts, must only be exchanged using
authorised parts.
3.
Set the slider to the off (O) position.
