This Gas Appliance Installation & Leak Test SOP (Safe Operating Procedure) covers how a licensed gasfitter connects, tests and commissions a gas appliance such as a cooktop, hot water unit or space heater on natural gas or LPG. It sets out isolating and purging the pipework, connecting the appliance, pressure and leak testing, checking ventilation and flueing, spillage testing, and commissioning and handover.

Common questions
Who can use this SOP?
Only gasfitters who hold the licence required for this class of work and have been assessed as competent and authorised. Licence and endorsements are confirmed as the first check.
Does it cover LPG cylinder storage or general gas installation design?
No. It covers connecting, testing and commissioning a specific appliance. Cylinder storage, exchange, transport and installation design are covered by other procedures.
Does it include carbon monoxide checks?
Yes. It includes checking combustion, testing open-flued appliances for negative pressure and spillage, and what to do if carbon monoxide poisoning is suspected.
Can I change it?
Yes. It's a Microsoft Word file, so you can add, remove or change any step, check or hazard, and add your own logo and details.
Does it suit my state?
Yes. It's written to the model WHS laws and suits all states and territories, including Victoria under the OHS Act and Regulations.
