giusp - flues in voids

  1. Flues In Voids. Break in chimney system or signs of distress to the material of the enclosure/ceiling around the chimney system where further investigation is prevented.
    ID

    In the circumstances where an ID situation has been identified, a RIDDOR report needs to be raised.
  2. Flues In Voids. Signs of distress to the chimney system e.g cracking or condensate leakage at joints.
    ID

    In the circumstances where an ID situation has been identified, a RIDDOR report needs to be raised.
  3. Flues in voids. Failure to achieve satisfactory combustion readings when using an electronic combustion gas analyser. Where the CO/CO2 combustion ratio is above 0.008 (appliances incorporating air/gas ratio valves only).
    ID
  4. Flues in voids. Failure to achieve satisfactory combustion readings when using an electronic combustion gas analyser. Where the CO/CO2 combustion ratio is between 0.004 and 0.008 (appliances incorporating air/gas ratio valves only).
    AR
  5. Flues in voids. No access or inadequate access provided to allow satisfactory visual inspection of chimney system/route. This includes the property in question and other properties through which the chimney passes through
    AR

    All installations without appropriate inspection access must be classified as AR and should not be used until access for inspection is provided.
  6. Flues in voids. Incorrect grade of plastic chimney system material used where there are signs of distress e.g. discoloration, or it is not possible to visually inspect the entire chimney system.
    AR

    Where the incorrect grade of plastic chimney system is used but has adequate access to inspect and ensure every joint is intact and the chimney system is appropriately supported then this can be classified as NCS.
  7. Flues in voids. Incorrect jointing methods used e.g. use of lubricant on push-fit fittings, or screws missing from mechanical joints.
    AR
  8. Flues in voids. Upon visual inspection, it is identified that the chimney system is insecure or inadequately supported.
    AR

    Evidence that the chimney system is inadequately supported includes insufficient clipping and sagging of pipe.
  9. Flues in voids. The overall chimney length exceeds the manufacturers specification.
    AR

    The appliance manufacturer should be contacted for their advice. Following this advice and after confirming the safe operation of the appliance (Including CGA) it may be appropriate to classify the installation as NCS.
  10. Flues in voids. For condensing appliances, upon visual inspection, it is identified that the chimney system does not have the manufacturers specified gradient of fall back to the appliance, or other drain points, but the appliance is operating safely.
    NCS
