MANTEL CLEARANCES
In addition to meeting noncombustible material
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, page 10).
Determining Minimum Mantel Clearance
When using a Hood
If minimum clearances in Figure 6, page 11 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
Figure 7, page 10 when using hood.
NOTICE: Surface temperatures
of adjacent walls and mantels be-
come hot during operation. Walls
and mantels above the firebox
may become hot to the touch.
If installed properly, these tem-
peratures meet the requirement
of the national product standard.
Follow all minimum clearances
shown in this manual.
NOTICE: If your installation does
not meet the minimum clear-
ances shown, you must do one
of the following:
• operate the logs only with the
flue damper open
• raise the mantel to an accept-
able height
• remove the mantel
