Safety distance from the wall covering
If a wall covering is installed, a minimum safety distance must be maintained be‐
tween the countertop cut-out and the covering, since high temperatures can dam‐
age these materials.
If the covering is made of a combustible material (such as wood), the distance be‐
tween the countertop cut-out and the wall covering must be a minimum of 2"
(50 mm).
For coverings made of non-combustible materials (such as metal, marble, granite,
ceramic tiles) the minimum safety distance between the countertop cut-out and
the wall covering must be 2" (50 mm) minus the thickness of the covering. For ex‐
ample: thickness of wall covering 2" (50 mm) - ⁹/₁₆" (15 mm) = minimum safety
distance 1 ³/₈" (35 mm).
