Note 1: From door opening. The depth of a non-combustible shelf in from of the insert
is included in the calculation of the floor protector’s dimensions.
IMPORTANT: The masonry hearth should be at least 4 inches (102mm) higher than
the combustible floor in front of it. If the hearth elevation is lower than 4 inches, the
non-combustible floor protector in front of the insert should have an R value equal or
greater than 1.00.
