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
&RPEXVWLEOH0DQWHO
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 below.
Conversely, a
1RQ&RPEXVWLEOH0DQWHO
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 below.

If appliance is installed
directly on carpeting or other
combustible material other than
wood flooring, a metal or wood
panel extending the full width
and depth of the appliance must
be used. Carpet may extend 1
inch above the floor of the
appliance.

Combustible objects must not be placed
on a Non-combustible Mantel unless the
mantel meets the dimensional
requirements for a Combustible Mantel.
Refer below to determine whether your
mantel conforms to the requirements of
a Combustible Mantel.
