The specified clearances provide the minimum distance to
combustible materials. If the appliance is intended to be
installed into a non-combustible opening the clearance to
the sides and above the appliance can be reduced.
However, it is recommended that the specified clearances
are maintained irrespective of the materials used in the
construction of the opening to allow adequate air flow and
access to controls. The clearance at the rear of the
appliance must always be a minimum of 50mm.
