VITOFLAME 200 Vitoflame 200 oil burner fitted to Vitorond200 5692452 GB2/2002 File in: Service folder General Information Safety instructions Please follow these safety instructions closely to prevent accidents and material losses. Work on the equipment Installation, initial start−up, maintenance and repairs must only be carried out by a competent person (heating engineers/ installation contractors) (EN50110, part1, and VDE1000, part10, or local regulations). Before working on the equipment/ heating system, isolate the mains electrical supply (e. g. by removing a separate mains fuse or by means of a mains electrical isolator) and safeguard against unauthorised reconnection. Disconnection must be carried out by means of an isolating device which simultaneously isolates all non−earthed conductors with at least 3 mm contact separation. Repair work It is not permitted to carry out repairs on parts that fulfil a safety function. Use only original Viessmann spare parts or equivalent which have been approved by Viessmann. Initial start−up This must be carried out by the system installer or a commissioning engineer designated by him; all actual values should be recorded in a commissioning/service report. Instructing the system user The system installer must hand the operating instructions to the system user and instruct him/her in the operation of the system. This symbol is a reference to other instructions which must be observed. Work requiring the control unit to be opened must not subject internal components to electrostatic discharges.

Check the CO content, CO2 content, flue gas temperature, room temperature and chimney draught after 2minutes operation and at 60 ºC boiler water temperature with fitted burner hood. Remove the burner hood before commencing maintenance work. Initial start−up 1. System start−up Service instructions Boiler control unit Please note: Vitoflame 200 oil burners have excellent combustion values which are achieved without the use of fuel oil additives to improve combustion. We do not therefore recommend the use of such combustion improvers. 1. Check whether the flame tube attachment (for 15 to 33 kW output) has been fitted. 2. Check the heating system pressure and the oil level in the tank. 3. Open the shut−off valves in the oil supply lines on the oil tank and on the filter. 4. Fill the oil suction line and filter with fuel oil using the manual oil suction pump before switching on the burner. 5. Switch on the mains electrical isolator (outside the boiler room). 5692452 GB 6. Switch on system On/Off switchB on the control unit. If fault indicator lampA on the control unit illuminates, press reset buttonC on the burner. Please note: For Vitorond 222: For balanced flue operation the air supply duct should be fitted before burner setup. Observe the following values during this step: H Pressure loss in the air supply duct max. 35 Pa, H Air inlet temperature in the inlet adaptor min. 5°C/max. 30°C. 5 Initial start−up, inspection and maintenance Implementation (cont.) Initial start−up Maint. 2. Oil pressure adjustment and vacuum check Please note: The oil pressure is preset at the factory according to the oil throughput. Adjust the oil pressure, if necessary. 1. Isolate the mains electricity supply and safeguard against reconnection. 2. Unscrew drain plug"P" A from the oil pump. 3. Unscrew drain plug"V" B from the oil pump. Please note: This allows the oil to drain from the oil pump. 4. Insert a pressure gauge (range 0 25bar) and a vacuum gauge (range 0 1bar); seal the gauges only with copper or aluminium rings or O−rings. Please note: Do not use tape to seal these joints. 5. Start up the burner. The solenoid valve opens. 6. Read off the oil and vacuum pressures of the pump on the relevant gauges (vacuum should be max. 0.35bar given a head of 3 m between the oil pump and the bottom of the tank). Where the vacuum measures higher than 0.35bar, check the filter for cleanliness or the pipe run. 7. If necessary, set the oil pressure on oil pump pressure setting screw C (for Danfoss pumps: depending on the model either on the front or the side). Turning clockwise³pressure increases Turning anti−clockwise³pressure decreases. Please note: For standard values for burner settings, see page22. Danfoss oil pump, typeBFP21 8. Check the emission values after checking the oil pressure. 9. Isolate the mains electricity supply and safeguard against reconnection. 10. Remove the pressure and vacuum gauges. 11. Insert drain plugs"P" A and"V" B. 12. Start up the burner and check the plugs for leaks. 6 Please note: Check the plug seal rings for possible damage and replace, if necessary. 5692452 GB Suntec oil pump, typeAL35 Initial start−up, inspection and maintenance Implementation (cont.)

Inspection Maint. 16. System start−up 1. Open the oil filter valve. 2. Switch on the mains electrical isolator (outside the boiler room). 3. Switch on the system On/Off switch on the control unit. Inspection Maint. 17. Checking the oil pipes and connections for leaks The presence of air bubbles in the prefilter is a sign of a leak in the suction line. Check oil pipes and connecting pipes on the oil tanks. Leaks will cause the fuel oil to continue to be injected (run−on) and produce soot deposits on the sensor plate and on the flame tube attachment. Maint. 18. Re−checking the burner Please note: The flue pipe must be sealed on the boiler adaptor. Infiltrating air leads to false readings. 5692452 GB Record all test values in the order of the commissioning/service report on the penultimate page of this manual. 14 Initial start−up, inspection and maintenance Burner control unit You may use the following burner control units with this burner: Burner control unit LOA 14.171B2V For programming sequence, see the wiring diagram on page 25. Sensor current: H min. requirement 50 µA H max. permissible without flame 5.5µA Undervoltage When the mains voltage falls below 165 V~, the burner will be prevented from starting or the oil flow will be interrupted; simultaneously the system will be initiating a fault shutdown. Fault position A lamp in the reset button also indicates the fault shutdown of the burner control unit. Please note: If the power supply is 2×127 V and a red flashing code: 10×flashing (see page 19) refer to your local Viessmann sales office. Control sequence in case of faults The fuel valve outputs and the ignition system are immediately shut down (< 1 s) if the system shuts down because of faults. Burner control unit LMO 14.113A2 For programming sequence, see the wiring diagram on page 25. Sensor current: H min. requirement 40 µA H max. permissible without flame 5.5µA Undervoltage If the mains voltage falls below 165V~ the burner control unit initiates a safety shutdown. The system re−starts when the mains voltage rises again above approx. 175 V~. Cause Response After mains power failure Re−start After falling below the undervoltage level Re−start In case of premature, faulty flame signal during the pre−flush time t1 Fault shutdown at the end of the pre−flush time t1 In case of premature, faulty flame signal during the oil pre−heat time t0 Starting will be inhibited after a maximum of 40sec. fault shutdown If the burner does not light within the safety limit t2 Fault shutdown at the end of the safety period t2 If the flame fails during operation Max. 3 start repeats, then fault shutdown No heating or oil pre−heater enabling within 10 min. Fault shutdown System creates a fault shutdown After a fault shutdown, the burner control unit remains locked out (non−modifiable fault shutdown) and the red lamp illuminates. This state is also maintained after the mains power supply has failed. 5692452 GB Controlled intermittent operation After a maximum of 24 hours non−stop operation, the burner control unit implements an automatic safety shutdown with subsequent re−start. Resetting the boiler control unit The system can be immediately reset after a fault shutdown. Hold down the reset button for approx. 1 sec. (<3 s). Ignition sequence The system is re−ignited, if the flame fails within the safety period, however not later than at the end of the safety period. This allows several ignition attempts within the safety period, see program sequence on page 25. switch−on (through temperature or pressure regulators, thermostat or pressure limiters or safety limiters). Repeat restriction The system may be re−ignited up to 3times, if the flame fails during operation. The fourth flame failure during operation triggers a fault shutdown.
