Mantel Requirements
Combustible Mantels
 Use the table below to determine the maximum mantel depth allowed. The mantel depth (measured
from the face of the fireplace) must fall in the shaded portion of the table.
 Any material that protrudes more than 3/4” (19mm) from the non-combustible facing is considered a
mantel and must meet the mantel requirements.
Examples:
- If you wish to have an 8” (203mm) deep mantel, it must be at least 8” (203mm) above the fireplace face (44-3/4”, 1137mm above the base).
- If you wish to have a mantel 6” (152mm) above the fireplace face, it must be no deeper than 6” (152mm).
Non-Combustible Mantels
Non-combustible mantels must meet the clearances listed for combustible mantels. However, if you do
wish to reduce the clearances by using a non-combustible mantel, the following requirements must be met:
 Non-combustible
mantel and facing
must extend from the
top of the appliance to
the top surface of the
mantel.
 A
non-combustible
header must be used
(metal stud).

Base of the Fireplace
Combustible mantel columns (legs) that protrude
more than 3/4" (.75mm) from the glass frame must
meet the sidewall clearance. If they protrude 3/4"
(.75mm) or less, they must meet the facing
clearance, 2-1/4" (57mm) from the glass frame - to
the side of the fireplace, not in front of it.
Non-combustible mantel columns do not have a
minimum clearance.
