MANTEL CLEARANCES
In addition to meeting noncombustible material
clearances, you must also meet required clearances
between fireplace opening and mantel shelf. If
you do not meet the clearances listed below, you
will need a hood.
Determining Minimum Mantel Clearance
If you meet minimum clearance between mantel
shelf and top of fireplace opening, a hood is not
required (see Figure 6).
Determining Minimum Mantel Clearance
When Using a Hood
If minimum clearances in Figure 6 are not met, you
must have a hood. When using a hood there are
still certain minimum mantel clearances required.
Follow minimum clearances shown in Figure 7
when using hood.
