•  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.

Base of the Fireplace

Combustible mantel columns (legs) that protrude 
more than 3/4" (0.75mm) from the glass frame 
must meet the sidewall clearance. If they 
protrude 3/4" (0.75mm) 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.

- 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 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). 

Drywall

Non-Combustible Mantel

Non-Combustible Framing (metal studs)

must be used for the header.
