11. Flame failure controller
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.
Operating Indicator LED:
LED is OFF: KLC is not switched on – no power supply
or ‘no flame’ is detected.
LED is FLASHING: KLC has detected a flame; the quality of the flame signal is indicated by the intensity of the
flashing of the LED – fast flashing indicates a healthy
flame signal and vice versa - slow flashing indicates a
weak flame signal.
LED is ON: KLC has detected the strongest level of
flame signal.
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.
E. 30.07.07 • G. 07.06.11

Page 6
• 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.
12. Oil connection
Oil lines must be routed to the burner as far as necessary to allow the oil hoses to be connected without
tension. Care must be taken to ensure that the burner can easily be moved into the service position.
Important: an oil filter must be installed before the oil pump.
The tables for single and double line installation show the maximum possible pipe length in dependence
on 3 factors with reference to heating oil type EL 4.8 cST.
• Height differential between pump and tank,
• nozzle delivery rate or pump type,
• pipe diameter.
4 brackets, 1 valve and 1 check valve for resistance were factored into the suction line length. Due to possible degassing of the oil, dimension "X" should not exceed a length of 4 m.
To convert the pump for operation on a single line system, the following points must be observed:
remove the return line and the connection nipple. Unscrew the bypass plug in the return line port and tightly
seal the port with a sealing plug. The pump suction flow will then be identical to the flow rate through the
nozzle.

The gas pressure monitor serves to monitor the gas inlet pressure. The burner is shut down if the gas inlet
pressure drops below the set minimum value (preset at factory). The burner starts up automatically again
when the minimum pressure is exceeded.
20. Function test
The flame monitor must undergo a safety test both at initial start-up and after modifications or if the system
has been out of use for a lengthy period of time.
Start-up test with blacked-out flame sensor:
The burner must go into lockout mode after expiry of the safety interval.
Start-up with exposed flame sensor:
The burner must go into lockout mode after approx. 20 s of pre-ventilation.

Screw the measuring nipple for combustion chamber pressure into the gas jacket at the top.
Route the connecting hose between the measuring nipple for combustion chamber pressure and the gas train in a loose loop.
The air pressure connection nipple must be screwed into the gas jacket at the top.
Connect the blue hose to the "AIR" connection on the gas train and the air pressure connection on the gas
jacket. The blue hose serves as a control line for the gas train and must be routed in a loose loop without
kinking.
Remove the plate for covering the adjustment screws from the gas pressure regulator.
Start the burner.
1. Setting the air surplus in high and low-load operation
• Set the air flap positions P9 for high-load operation and P1 for low-load operation according to
29. Adjustment tables. Follow the setting procedure described in 19. Adjustment mode for pneumatic
gas-fired operation with MPA 22 display.
• In high-load operation, set the air surplus with the "large flame" adjustment screw on the gas pressure
regulator. The CO2 level in the flue gas should be 9-10% for natural gas.
• In high-load operation, set the air surplus with the "small flame" adjustment screw on the gas pressure
regulator. The CO2 level in the flue gas should be 9-10% for natural gas. The low-load setting influ-
ences the high-load setting.
• In high-load operation, check the air surplus and, if necessary, correct the setting with the "large
flame" adjustment screw on the gas pressure regulator.
2. Setting the output in high and low-load operation
• Check the high-load setting via the gas flow at the gas meter or compare the nozzle pressure with the
values stated in 27. Adjustment tables. The output can be increased by opening the air flap (to
increase P9) and reduced by closing the air flap (to reduce P9). The air surplus is not affected by this
adjustment.
• Check the low-load setting via the gas flow at the gas meter or compare the nozzle pressure with the
values stated in 27. Adjustment tables. The output can be increased by opening the air flap (increase
P1) and reduced by closing the air flap (reduce P1). The air surplus is not affected by this adjustment.

Screw the air pressure measuring nipple into the gas jacket at the top.
Route the connecting hose between the air pressure measuring nipple and the gas train in a loose loop.
The air pressure connection nipple must be screwed into the gas jacket at the top.
The blue hose serves as a control line for the gas train and must be routed in a loose loop without kinking.
Cut the blue hose into two sections. Connect the first sections of blue hose to the "pL" connection on the
gas train and the air pressure connection on the gas jacket, and connect the other section to the "pF" measuring point on the combustion chamber. The hose must be routed in such a fashion that any condensate
forming inside the combustion chamber flows back, and not into the gas train.
Start the burner.
1. Setting the air surplus in high and low-load operation
• Set the air flap positions P9 for high-load operation and P1 for low-load operation according to
29. Adjustment tables. Follow the setting procedure described in 19. Adjustment mode for pneumatic
gas-fired operation with MPA 22 display.
• In high-load operation, set the air surplus at the adjustment screw "V" on the gas pressure regulator.
The CO2 level in the flue gas should be 9-10% for natural gas.
• In low-load operation, set the air surplus with the adjustment screw "N" on the gas pressure regulator.
The CO2 level in the flue gas should be 9-10% for natural gas. The low-load setting influences the
high-load setting.
• In high-load operation, check the air surplus and, if necessary, correct the setting using the adjustment
screw "V" on the gas pressure regulator.
2. Setting the output in high and low-load operation
• Check the high-load setting via the gas flow at the gas meter or compare the nozzle pressure with the
values stated in 27. Adjustment tables. The output can be increased by opening the air flap (to
increase P9) and reduced by closing the air flap (to reduce P9). The air surplus is not affected by this
adjustment.
• Check the low-load setting via the gas flow at the gas meter or compare the nozzle pressure with the
values stated in 27. Adjustment tables. The output can be increased by opening the air flap (increase
P1) and reduced by closing the air flap (reduce P1). The air surplus is not affected by this adjustment.
