Safety distance when installing the appliance near a wall with additional
niche cladding
If a niche cladding is installed, a minimum safety distance must be maintained
between the worktop cut-out and the cladding, since high temperatures can dam-
age these materials.
If the niche cladding is made from a combustible material (e.g. wood) a minimum
safety distance  of 50 mm must be maintained between the worktop cut-out and
the cladding.
If the niche cladding is made from a non-combustible material (e.g. metal, natural
stone, ceramic tiles) the minimum safety distance  between the worktop cut-out
and the cladding will be 50 mm less the thickness of the cladding.
Example: 15 mm niche cladding
50 mm - 15 mm = minimum safety distance of 35 mm
