15. FULL OPERATING CHECKS
15.1 Check the control settings.
With the ceramic fuel effect in position the control operation must now be fully
rechecked. Make sure that the isolating valve at the elbow is open.
!
When first turned on from cold, the flames will appear predominantly blue.
!
When operating the fire for the first time, some vapours may be given off which
could set off smoke alarms in the vicinity. These vapours are quite normal with new
appliances. They are totally harmless and will disappear after a few hours use
.
15.1.1
Lighting the burner.
1.
If closed
,
open the isolating valve at the inlet elbow.
2.
Depress the control knob and rotate it anticlockwise to the pilot ignition position. A
'click' will be heard as the integral piezo operates. A spark should be seen between the
electrode and pilot tip.
3.
Turn the control knob clockwise to the 'Off' position. Repeat this operation until a
flame appears at the pilot. There may be a delay before the pilot lights due to air being
purged from the system. When a flame appears at the pilot keep the control knob
depressed and hold the pilot ignition position for five seconds. When the control knob is
released the pilot flame should remain lit.
15.1.2
Operating the burner.
1.
When the pilot burner is operating properly, gradually turn the control knob anti-
clockwise to 'HIGH' (Depress the knob slightly to get past the pilot ignition position).
The main burner should now light. Depress the control knob slightly to release from the
'HIGH' position and turn back (clockwise) to 'LOW'. While turning, the burner flames
should gradually become lower but remain alight. Depress the control knob slightly to
release from the 'LOW' position and turn back (clockwise) to the Pilot ignition position.
The main burner should extinguish but the pilot should remain alight. Depress the
control knob slightly and turn back (clockwise) to turn OFF.
This will extinguish the pilot.
If the above checks are satisfactory, continue with the installation. If not, check the
control and ignition circuitry and components as described in the servicing section of
this guide.
While cooling the ceramic fuel effect may make some crackling noises. This is quite
normal.
