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 6-3/4" (171mm) above the fireplace face (44-3/4", 1137mm above the base).
- If you wish to have a mantel 8" (203mm) above the fireplace face, it must be no deeper than 9" (229mm).
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).

Combustible mantel columns (legs) that protrude
more than 3/4" (20mm) from the glass frame
must meet the sidewall clearance (1" (25mm)
from fireplace, 3-1/4" (83mm) from the glass
frame). If they protrude 3/4" (20mm) or less, they
must meet the facing clearance 2-1/4" (57mm)
from the glass frame.
Non-combustible mantel columns do not have a
minimum clearance.
