MANTEL CLEARANCES
In addition to meeting noncombustible ma-
terial clearances, you must also meet re-
quired 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 clear-
ances shown in Figure 7 when using hood.
