7. CONTROL AND PRESSURE CHECKS
7.1 Check control settings.
1. If closed
,
open the isolating valve at the inlet ‘T’ connector.
2. To check the control positions temporarily place the fascia loosely over the engine.
Fit the control knob over the gas tap spindle.
3. Depress the control knob and slowly 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 slowly
turn the knob anticlockwise. A second spark should be generated at the pilot while
turning. This spark should ignite the pilot.
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 guide).
5. Check all the control settings. These are: -
7.2 Flame supervision and 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:
1. Light the appliance. Set at position 5 and leave for one minute.
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.
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
Valor Fires authorised parts.
