Latest information on AS NZS 5601 1 the gas installations standard

Issue 51 – July 2013

The Gas (Safety and Measurement) Regulations now cite AS/NZS 5601.1:2010 Gas installations – Part 1: General installations instead of NZS 5261.2003 Installation of gas burning appliances and equipment. Energy Safety; the Plumbers, Gasfitters and Drainlayers Board; and Standards New Zealand have developed a short presentation on what this means for practitioners.

This presentation outlines aspects of AS/NZS 5601.1 that differ from NZS 5261. AS/NZS 5601.1 also incorporates several technical and editorial amendments.

Major changes in this revision include:

  • additional requirements for the use of proprietary multilayer piping systems
  • changes to the installation of a freestanding cooking appliance connected with a hose assembly
  • revision of the appendix on pipe sizing – Appendix F
  • inclusion of a new appendix on gas in high-rise buildings – Appendix K
  • inclusion of a new appendix with diagrammatical representation of outdoor areas – Appendix I.

The presentation also discusses the mandatory change on negative air pressures, along with several key changes to means of compliance.
