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 Fig- ure 7 when using hood.

•operate the logs only with the flue damper open

•raise the mantel to an acceptable height

•remove the mantel

FLOOR CLEARANCES

A.If installing appliance on the floor level, you must maintain the minimum distance of 14" to combustibles (see Figure 8).
