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
