Page 5: Conventions In This Manual
Conventions in this Manual Read these instructions carefully before installation, commissioning or maintenance of the burner. The given instructions must be followed. Throughout this manual, the following three symbols are used to point out very important information: WARNING! A warning alerts you to possible danger to person, if the instructions are not followed. -
Page 6: General
The oil supplied to the burner must be filtered before the burner oil pump. Filtration degree is from 20 - 40 μm. We recommend mounting of an Oilon Plus filter and deaerator unit. Oil atomizing pressure 800 - 1400 kPa (8 - 14 bar). Factory setting approx. 10 bar. - Page 7 CAUTION! The burner must be installed firmly. Vibrations may damage burner or its components. CAUTION! Disconnect the plug connector before burner maintenance or removal from the boiler. See chapter ”Connecting the Burner to the Mains”. WARNING! In case of fire or other danger: switch off the main switch close the main fuel shut-off valve outside the plant take appropriate actions.

Page 13: Burner Installation
Burner Installation 4.1. Burner Mounting The furnace, which has a flame-shaped design, does not require refractory. Boilers without bottom cooling require refractory to prevent heat from reaching boiler foundations. The flame must at no point come into contact with the furnace walls. If this cannot be avoided, such points must be covered with refractory. -

4.2. Hinged Burner Housing As standard the burner can be hinged to both sides. 4.3. Electric Connections The burner must be connected according to the electrical diagrams delivered together with the burner. General and local standards and regulations as well as requirements of electrical equipment on electrical connections must be adhered to. -

Page 21: Burner Adjustment
Burner Adjustment 7.1. Capacity Regulation Adjust the burner thermal output by changing the size of the nozzle or the oil pump pressure. Combustion air quantity (and position of the adjustment ring on burner types J50 and LJ50) must be checked after having changed the nozzle. See chapter ”Change of Nozzle”. 7.1.1. -
Page 22: 7.1.2. Oil Pump Pressure Regulation
7.1.2. Oil Pump Pressure Regulation Fit a pressure gauge in the connection (see chapter ”Oil Pumps”). Adjust the oil pressure by turning the pressure regulating screw.

Page 24: Nozzle And Ignition Electrode Settings
7.3. Nozzle and Ignition Electrode Settings The measures shown are for guidance. They may vary according to the nozzle type being used. The oil spray must not come into contact with the electrodes and the diffuser disc. The electric arc should be created at that point in the oil where the spray begins. The ignition electrodes must not come into contact with diffuser disc. -

7.5. Adjusting the Air Velocity in the Combustion Head J50, LJ50 Adjust the air velocity in the combustion head by turning the setting screw (5), to change the distance between the adjustment ring and the edge of the diffuser disc (4). There is a scale with four grooves in the combustion head, which is directed to the back edge of the adjustment ring according to the capacity. -
Page 26: Adjusting The Distance And Centrality Of The Nozzle
7.6. Adjusting the Distance and Centrality of the Nozzle Distance Loosen the locking screws (2) but not more than that the cover plate keeps contact with the burner housing. Move the cover plate in the direction of slots (see for L-measure the chapter ”Nozzle and Ignition Electrode Settings”) and tighten locking screws (2). -
Page 27: Combustion Air Adjustment
7.7. Combustion Air Adjustment Make sure that air, required by the burner, enters the boiler room through the fresh air ventilator. The ventilator must not be closed. The fresh air inlet must be led to the top of the room. Eventual outlet valve has to be closed in wintertime. Check, that the self-closing air flap (5) moves easy and that it is positioned according to the drawing. -

Page 30: Control Functions In The Event Of Faults
8.2. Control Functions in the Event of Faults Extraneous light / premature flame signal During pre-purge and/or pre-ignition period there must never be a flame signal. If there is a signal during this period, caused possibly by premature ignition due to a leaking oil valve, extraneous light, a short-circuit in the flame detector (photo resistor) or its wiring, a fault in the flame signal amplifier, etc., the control unit locks out on expire of the pre-purging and safety period. -
