    GENERAL INSTRUCTION Flame monitoring and measurement of ionisation current The burner is monitored according to the ionisation principle. Check the ionisation current on start-up and on each service call. The reason for a low ionisation current may be leaking currents, bad connection to earth, dirt or a faulty position of the flame electrode in the burner head.
  • Page 21 GENERAL INSTRUCTION UV-detector This should not be exposed to temperatures exceeding 60°C. The current passing through the UV-detector, when it is being illuminated, should be at least 70 µ A for LFL1.. This current can be measured by means of a moving coil instrument.
  • Page 22 GENERAL INSTRUCTION Adjustment of air pressure switch The air pressure switch should stop the burner, if the air volume is reduced. The air proving device shall be adjusted in such a way that if there is insufficient air supply at the highest or lowest burner operating stage, the device operates before the supervised pressure is less than 80% of the pressure at the controlled stage and the CO content of the combustion products exceeds 1% by volume.
