MANTEL CLEARANCES
In addition to meeting noncombustible mate-
rial clearances, you must also meet required
clearances between fireplace openings and
mantel shelf on each side of the fireplace. 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 clear-
ances required. Follow minimum clearances
shown in Figure 7 when using hood.
