Australian Standards for electric/gas oven installation are used to make sure kitchen appliances are safely used and correctly installed.
For electrical appliances, only a licenced electrician can install as there are electrical circuits and multiple wires involved. The electrician also needs to look into your existing wiring to ensure that your wiring is capable of handling the requirements of your new oven or cooktop. Newer models can often require increased circuitry.
If you need to upgrade your wiring to suit the power needs of your new oven, a site inspection can be arranged to provide a quote to do this.
For gas appliances, ONLY a licenced gas fitter/plumber can install. Gas is dangerous and the gas needs to be connected to the correct gas line and adhere to regulations around minimum clearances for combustible materials.
When the installation is completed, your electrician or plumber will provide you with a Compliance Certificate.
