Figure 6 - Minimum Mantel Clearances Without Using Hood
Mantel Clearances
In addition to meeting non-combustible
material clearances, you must also meet
reaquired clearances between fireplace open-
ing and mantel shelf. If you do not meet the
clearances listed below, you will need a
hood.
Determing 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 Clear-
ance When using a Hood
If your installation does not meet the above
minimum clearances, you must:
• operate the logs only with the flue
damper open, OR
• raise the mantel to an acceptable height,
OR
• remove the mantel.
