MQRB5143 Mantel 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 below.
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.
-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.
Refer below to determine whether your
mantel conforms to the requirements of
a Combustible Mantel.
The advantage to Non-Combu
stible 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.
