Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites


Course Description

This unit of competency specifies the outcomes required to design, size and document a consumers gas installation, including consumer piping operating up to a pressure of 200Kpa, fluing, ventilation and appliance installation associated with natural gas (NG), simulated natural gas (SNG),liquefied petroleum gas (LPG) and tempered liquefied petroleum gas (TLPG) for a building of minimum four floors and multiple buildings supplied through one gas source (billing meter or storage tank).
It covers preparing for work, determining gas installation design requirements, detailed planning of the layout, and completing work finalisation processes, including records and documentation.
