This Standard sets out requirements for consumer piping, flueing, ventilation and appliance installations which are associated with the use or intended use of fuel gases such as Town Gas, Natural Gas, Liquefied Petroleum Gas in the vapour phase, Tempered Liquefied Petroleum Gas, Simulated Natural Gas or any similar substance.
The requirements cover piping systems from the outlet of:
(a) the consumer billing meter installation
(b) the first regulator on a fixed gas installation where an LP Gas container is installed on the same site or,
(c) the first regulator on site (if no meter is installed) where LP Gas is reticulated from storage off the site;
to the inlet of the appliance.
This Standard does not apply to portable or mobile appliances (such as barbecues) which are designed for external use only and are connected directly, or by hose assembly, to a LP Gas cylinder.
Requirements for installations for caravans and marine craft including location of storage cylinders, piping systems and appliances are also provided in this Standard.
NOTES:
1 The location of consumer billing meters is determined by the appropriate Authority having jurisdiction; however, some guidelines for the locating of these meters are detailed in Appendix A.
2 The terms pipe, piping, tube and tubing are used throughout this Standard. They are to be considered to have the same meaning.
Unless specifically covered in this Standard, where consumer piping is to operate at a pressure exceeding 200 kPa, consult with the Authority.
Appliances provided for in this Standard include those approved under an Australian Gas Association scheme (ie. ‘general approval’ and ‘individual approval’ (Second Tier), and those otherwise acceptable to the Authority.
The appliance installation requirements cover location, ventilation, combustion air, flueing and commissioning of the appliance.”
