Mounting instructions
The KLC 20 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 avoid any disturbance, do not align the detector direct to the ignition spark. Breakdowns during pre-
ventilation procedure may occur. The maximum length of the connection must be in accordance with the
technical data. Install the detector connection cable with most possible distance to the ignition cable.
Attention:
For safety reasons and technical regulations a controlled burner shut down of at
least once per 24 hours must be guaranteed.
