Safety distances
A gas appliance shall be installed such
that the surface temperature of any
nearby combustible surface* will not
exceed 65 °C above ambient.
The minimum clearance from a
combustible surface shall be a 200 mm
horizontal distance from the periphery
of any gas burner (AS 5601).
If that horizontal clearance is less than
200 mm, that vertical surface must be
protected by a non-combustible
material for 150 mm above the cooktop
surface across the entire length (depth,
width).
The shown area indicates the protected
surface, which may be ceramic tiles or
other approved material.
*Combustible surface:
A material which will ignite and burn,
and includes material which has been
flameproofed.
