TRANSPORT, INSTALLATION AND CONNECTION
4.5 Installation
All installation and connection work may be carried out by qualified and approved
specialist staff only! The legal regulations as well as adjustment instructions of the
plant operator have to be observed!
NOTICE
The KLC 20 / KLC 21 should be mounted close to the flame with straight alignment. The compact
flame detector should be mounted with the mounting flange KLC or another suitable holder with
Ø14 mm opening. The radial adjustment to the flame is realised with the viewing angle adapter KLC
and replaces the mounting flange KLC. Fix the detector with the holder. The best flame signal will
be achieved from strong flickering parts of the flame radiation. The angle of view, especially with
sight tubes, must be of appropriate dimensions to avoid any reduction of flame radiation. Protect
the sensor against other light sources.
To prevent faults, the direct view of an ignition spark must be avoided. Faults in the prepurge phase
can be caused by this. The maximum cable length of the connection cable must be observed. The
connection cable must be kept separate from high-energy ignition and mains cables and must not
be laid parallel to them over long distances.
Attention: For safety reasons and technical regulations a controlled burner shut down of at least
once per 24 hours must be guaranteed.
For the mounting BST Solutions offers different accessories:
4.5.1 Mounting flange KLC
The mounting flange KLC serves for to the admission, attachment and adjustment of the flame
detector. Two overall heights with 7 and 13 mm are available. By means of an O-ring the mounting
flange KLC can be simply sealed to the burner housing.
