    GENERAL INSTRUCTIONS Adjustment of burner The burner is from the factory pre-set to an average value that must then be adjusted to the boiler in question. All burner adjustments must be made in accordance with boiler manu-facturers instructions.These must include the checking of flue gas temperatures, average water temperature and or O concentration.
  • Page 19: General Instruction

    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 20: Uv-Detector

    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 21 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 insufficien 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.
  • Page 22 FINAL TEST OF THE INSTALLATION - Make repeated start attempts to ensure that the adjustments function. - Close the ball valve during operation to check that the gas switch switches off at the set value. - Remove the hose for the air pressure switch to check that the burner locks out.
