MANTEL CLEARANCES

In addition to meeting noncombustible mate- rial clearances, you must also meet required clearances between fireplace opening and mantel shelf. If you do not meet the clear- ances 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 Clearances when Using a Hood

If minimum clearances in Figure 6 are not met, you must have a hood. When using a
