Commissioning and Maintenance
The installation and commissioning must be done by qualified personnel only. Before energising the KLC
flame detector please check the cable and wiring connections are in accordance to the diagram and
instructions given above. For good maintenance which will ensure trouble free operation of the KLC flame
detector; please keep the sight glass clean by wiping with a soft dry clean cloth. Warning: Do not use any
kind of cleaning sprays or fluids.
During commissioning and after any cleaning maintenance, the flame detector should be checked, as the
UV tube is subject to a natural ageing process and towards the end of its life span it is prone to
malfunction. To check that the flame detector is sound we recommend the following procedures be
followed:-
•
Start the burner with the fuel supply closed-off or remove the flame detector from its mounting
flange and cover the UV tube using a soft cloth to avoid touching the glass lens. The control box
will lock-out at the end of the safety time due to absence of a flame signal.
•
Remove the flame detector from its mounting flange. Start the burner while exposing the flame
detector to an external UV radiation source such as a cigarette lighter flame, or a small gas flame
(n.b. electric room lighting or a torch is inadequate). The burner Control Box must go to lock-out
due to detecting an extraneous light source either immediately or at the end of the air pre-purge
cycle, depending on the type/model of the Control Box.
•
Close off the fuel supply or remove flame detector from its mounting flange and cover the UV tube
using a soft cloth when the burner is in the "run" position. The control box must go immediately to
lock-out resulting in the burner shutting down.
If any of these safety checks do not function as described i.e. they should always result in burner
shutdown and control box lock-out; then it is essential to replace the flame detector with a new KLC flame
detector. For safety and trouble free burner operation, we recommend that the flame detector should be
replaced after every 10,000 hours of burner operation or approximately every 30months for a burner
operating on an average of 10 hours per day.
