Mantel Leg Clearances
Before installing any mantels it is
important to determine the
combustibility of its material(s). There
are two types of mantels to consider:
Combustible and Non-Combustible.
A
Combustible Mantel
is one that
consists of material(s) that may
discolor, combust, or lose its integrity
in the presence of heat. These types
of mantels must strictly conform to the
dimensional requirements shown.
Conversely, a
Non-Combustible
Mantel
is one that is constructed with
material(s) that will not combust.
Check your local codes and
regulations to determine whether your
mantel is Combustible or Non-
Combustible.
The advantage to Non-Combustible
Mantels is that it may extend right up
to the tile lip of the fireplace.
Combustible mantels must adhere to
the dimensional restrictions shown.
-Combustible Objects on Non-
Combustible Mantel Warning-
Combustible objects must not be placed on
a Non-combustible Mantel unless the
mantel meets the dimensional requirements
for a Combustible Mantel. Determine
whether your mantel conforms to the
requirements of a Combustible Mantel.
