  • Inspection of the combustion air supply
  • Visual inspection of all components and fittings
  • Preparation of the adjustment protocol and documentation
  • Fitting of gas lances and nozzles
  • Leak test of all pipes and instruments
  • ...

 

Safety inspection and maintenance of the burner

  • Burner complies with the legal requirements for (periodic) safety inspection
    • Certification
  • Doesn’t the burner meet the legal requirements?
    • Clear and specific description of the problems so that they can be discussed with you and the necessary actions can be taken
