Page 17: Nozzle Assembly Adjustment
General 3.1.2 Nozzle assembly adjustment The burner is equipped with a control which changes the position of the brake plate in the blast tube. This is used to set the correct pressure differential across the combustion device and thereby get a good combustion without pulsations. The setting to be used depends on the set effect and the overpressure in the boiler. -
Page 18: Inlet Cone, Air Control
General 3.1.5 Inlet cone, air control The air flow is also affected by the position of the intake cone. This rarely needs adjustment, however, and should be maintained in the standard position ”STD” for good operation and starts. (A cast-in arrow on the fan housing indicates the position of the inlet cone. -

Page 32: General Instructions
General 6. GENERAL INSTRUCTIONS 6.1 Flame monitoring and ionisation current check The burner is monitored according to the ionisation principle. The ionisation current should be checked at initial starting and at each service visit. The reason for low ionisation current can be leakage current, poor connection to earth, fouling or incorrectly placed ionisation electrode in the combustion head. -
Page 33: Setting Of Air Pressure Switch
General 6.1.4 Setting of air pressure switch The air pressure switch should block the burner if the air quantity is insufficient. The air monitoring device should be set so that, if there is missing air supply at the burner’s max. or min. capacity, it reacts before the monitored pressure is less that 80% of the pressure on the controlled stage and before the CO-level in the flue gases exceeds 1 per cent by volume. -

Page 40: Fault Location Guide
General 8. FAULT LOCATION GUIDE 8.1 Gas Burner A system’s prerequisites for trouble-free operation can be secured only by the tuned interaction of the three factors, electricity, gas flow and air supply. Should any one of these factors change, this can cause a breakdown. It has been shown that most breakdowns are caused by rather uncomplicated things. - Page 41 General Cause Corrective Action No flame creation in spite of faultless start Gas solenoid valve defective Replace The gas solenoid valve does not open in Replace the solenoid valve coil, spite of receiving voltage. possibly the entire valve.
