Lighting the fire
Manual version
The positions of the control valve are depicted on the control panel fitted around the control knob.
If the main burner or pilot light are extinguished for any reason,
do not attempt to relight the pilot
within 3 minutes.
The OFF
Ɣ
position is self explanatory - preventing any gas from passing through the control valve
to either the pilot burner or to the main burner.
By pressing the control knob in it is possible to turn it anti-clockwise. The first function is to turn on
the gas to the pilot - this occurs just before reaching the PILOT position. (If the fire has not been lit
for some time it may be necessary to hold the knob in this position for some seconds to clear the air
from the pipe and allow gas to reach the pilot burner.) Once gas is available at the pilot, continued
rotation anti-clockwise will cause the piezo igniter to spark. This is accompanied by a click at the
valve, and should result in the pilot burner igniting.
Once the pilot is lit, the control knob should be held pressed in for 10-12 seconds. In this time the
pilot flame will have heated the flame supervision thermocouple sufficiently to operate a hold-on
magnet within the valve. The knob should then be turned so that the pointer is approximately
vertical. This allows gas at a low rate to enter the burner and be ignited by the pilot flame. Once
ignition has taken place, the fire may be set to any level between MAX. and MIN. by adjusting the
control knob accordingly.
To turn off the main burner, turn the control to MIN. - press the knob in gently until it will turn
clockwise to the PILOT position. To turn off the pilot press knob and turn to OFF
Ɣ
Thus the sequence is:
To light
1. Remove the ash pan cover.
2. From OFF
Ɣ
press the control knob in and turn slowly anti-clockwise.
3. When the ignition click occurs check that the pilot is lit. (If not repeat 2 and 3).
(If the ignition system fails the appliance may still be lit using a taper to ignite the pilot, instead of
the spark. The taper should be introduced between the front and rear bed coals on the right
hand side).
4. Hold the knob in for 10 - 12 seconds.
5. Release knob and check pilot remains alight.
6. Turn knob until pointer is vertical, the fire should then ignite.
7. Adjust flames to required level without pressing the knob.
To extinguish
1. Turn control knob clockwise to MIN. position.
2. Press knob gently until able to continue turning clockwise to PILOT.
3. To extinguish the pilot, press knob and turn to OFF
Ɣ
, although it is in order to leave the pilot
permanently lit.
