Buying safe gas appliances

What to look for when buying a gas appliance

The right appliances

To protect your investment and safety, choose gas appliances that have been certified by the Australian Gas Association (AGA), SAI Global, IAPMO, Global-Mark or Vipac. Look for the certification label that indicates the appliance meets certain safety standards in its design and manufacture.

Appliance retailers are required to sell appliances that comply with the relevant safety standards, and have been labelled or badged to indicate acceptance under current standards.

Compliance marks may look like the following:

The right gas

Check the identification plate to find out if the appliance is suitable for the available gas. If in doubt, check with the appliance retailer, your gas supplier or your licensed gasfitter.

Natural Gas and LP Gas (LPG) are not the same, and operating an appliance on the wrong type of gas can be hazardous.

If you buy a second-hand appliance, always check the identification plate to ensure it is a certified natural gas or LP Gas appliance, and have it serviced by a licensed gasfitter when installed.

Never connect an LP Gas appliance to a natural gas supply unless it has been converted to run on natural gas – not all LP Gas appliances can be converted to run on natural gas. Conversion of gas appliances at your home from one gas to another must be done by a licensed gasfitter who is endorsed for gas conversion work.

Common appliance problems

Gas appliances need regular servicing as:

  • Burners in water heaters and space heaters can become blocked with dust or lint and congest the heat exchanger and flue passageways,
  • Air filters, air passageways and fans can become blocked or limited by lint and dust, leading to overheating and burner problems, and
  • Safety controls can wear out and fail.

As appliances age, these problems can become critical.

Get your appliance serviced

Annual servicing of water heaters and space or central heaters is recommended, especially after the first few years. Annual servicing is essential for older appliances in confined spaces, e.g. instantaneous gas water heaters in laundries or hall cupboards – these appliances should be removed from toilets or bathrooms.

Always follow the manufacturer’s service plan. Make sure the service person is qualified – only use a registered or licensed gas fitter who has completed the Master Plumbers CO training course. Keep a note on the appliance of the date it was serviced.
