Some local Codes of Practise may stipulate a shut off valve to stop the gravity flow of oil into the supply line during burner shut down. -weishaupt- recommend the use of a solenoid valve ➁ in ➀ ➀ the supply line. The solenoid valve must be slow closing so as to relieve any oil pressure back to the oil tank.
4.5 Burner installation Prepare heating appliance Refractory and drilling dimensions The diagram shows the refractory for a heating appliance without a cooled front. The refractory can be flat faced, or Refractory take a conical shape (≥ 60°). Refractory may not be required on boilers with water-cooled fronts, unless the Flange gasket manufacturer gives other instructions.
4.6 Electrical connection Check polarity of the connection plugs. Electrical connection Wiring diagram see Ch. 5.5. Connection to the mains supply should be carried out to the wiring diagram relevant for the type of unit. Notes for Austria Electrical isolation with a minimum of 3 mm contact gap, acting on all poles, must be fitted adjacent to the burner.
5 Commissioning and operation 5.1 Safety notes on initial commissioning The initial commissioning must only be carried out by the Furthermore the correct fusing of the circuits and the supplier, manufacturer or their appointed agent. At this measures for contact protection of electrical equipment time, all the control and safety equipment must be and of all wiring must be checked.
5.3 Commissioning and setting Initial setting values for diffuser and air damper Generally, CO values between 12.0% and 13.0% are The burner can be preset for first commissioning using the achievable at the presetting stage. Presetting does not scale values for setting the diffuser and the air damper. replace the necessary flue gas measurements and The setting values are based on maximum combustion combustion optimisation.

7 Servicing 7.1 Safety notes on servicing Failure to carry out maintenance and service Qualified personnel work properly can have severe consequences, Only qualified and experienced personnel must carry out including the loss of life. Pay close attention to maintenance and service work. the following safety notes.
7.3 Removing and refitting nozzle Removal Changing the nozzle WL10/2-C 1. Remove burner and place into service position (see Ch. 4.5) 2. Remove ignition cables 3. Remove screw 4. Remove diffuser from the nozzle assembly 5. Remove nozzle When changing the nozzle support the nozzle assembly.
7.5 Mixing head setting If the combustion head and the diffuser have heavy soot Setting the mixing head deposits, or are very oily internally, the combustion head settings must be checked. Dimension S1 (distance from the diffuser to the front edge of the flame tube) can only be checked when the burner is mounted onto a hinged boiler door.
7.8 Service position 7.9 Removing and refitting oil pump, fan motor and fan wheel Screw accessible via hole in fan wheel. When fitting, the screw should sit in the recess of the motor shaft.
