Standards requirement
Temperature of nearby surfaces. Australian and New Zealand Gas Installation Standards
(AS/NZS5601.1) require a cooktop to be installed so that the surface temperature of any
nearby combustible surface will not exceed 65°C above ambient.
This is typically achieved by:
■ having the cooktop spaced away from the wall (see gures 2a, 2b);
AND
■protecting the wall to a height of at least 150 mm along its length (minimum height of
non-combustible material when used on adjacent walls) with non-combustible surface
materials such as:
– 5 mm-thick ceramic tiles (these alone are adequate);
– tempered glass or sheetmetal, minimum thickness 0.4 mm (acceptable when used
in front of a re resistant material).
