Many installed gas cooking appliances are failing to comply with clearance requirements and thermal protection in relation to combustible surfaces.
Clearance requirements :
The specified clearance, measured from the outer edge of the nearest burner to any vertical combustible surface, should be at least 200mm.
When the distance is less than 200mm :
Where the distance is less than 200mm, the combustible surface is required to be protected to a minimum height of 150mm above the outer edge of the nearest burner for the full area (width and depth) of the cooking surface area (refer to label C in the image below) with a suitable fire-resistant material.
Certification of toughened glass :
Toughened safety glass may be used to protect the combustible surface, however, certification of the toughened safety glass is required and must be installed on appropriate fire-resistant backing material.
Note : Toughened safety glass used as a splashback must comply with AS/NZS 2208 and needs to be marked accordingly to indicate it is fit for purpose. Alternatively, a certificate from the manufacturer must be supplied to demonstrate that the safety glass is compliant and fit for purpose
