7.1 Check Control Settings

7.1.1 If closed open the isolating valve at the inlet elbow.
,
7.1.2 To check the control positions temporarily place the outer case loosely over the
engine. Fit the control knob over the gas tap spindle.
7.1.3 Depress the control knob and turn anticlockwise partially towards the 1/IGN
position until some resistance is felt. Keep depressed at this position for a few seconds to
purge air from the system then, while keeping it depressed, turn fully to the 1/IGN
position. A spark should be generated at the pilot while turning. The spark should ignite
the pilot. If it does not, keeping the knob depressed, continue to turn the knob
anticlockwise. A second spark should be generated at the pilot while turning. This spark
should ignite the pilot
7.1.4 When pilot ignition has been achieved, keep the control knob depressed for
approximately ten seconds to allow the thermocouple probe to warm up and then release
it. If the pilot does not remain alight, ensure that the air has been purged, that the pilot
orifice is clear and that the thermocouple connections are sound. Replace the pilot unit if
necessary (see servicing section of this manual).
7.1.5 Check all the control settings. These are: -
Knob Radiants Condition
Position
2 Centre radiant on low. Outer radiants off.
3 Centre radiant fully on. Outer radiants off.
4 Centre radiant fully on. Outer radiants on low.
5 All radiants fully on.
7.2 Flame Supervision & Spillage Monitoring System
The pilot unit incorporates 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 lack of
ventilation.
Check that the system operates properly as follows;
7.2.1 Light the appliance. Set at position 5 and leave for one minute.
7.2.2 Turn back to "OFF" to extinguish the pilot. 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. An
electromagnetic valve shutting off the gas supply through the tap causes this sound. 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.
