you must have noncombustible material be-
hind it. Noncombustible material must extend
at least 8" up. If noncombustible material is
less than 12", you must install the fireplace
hood accessory. Even if noncombustible
material is more than 12", you may need the
hood accessory to deflect heat away from
your mantel shelf. See Figures 5, 6 and 7, for
minimum clearances.
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 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.
NOTICE: Surface temperatures
of adjacent walls and mantels
become hot during operation.
Walls and mantels above the
firebox may become hot to
the touch. If installed properly,
these temperatures 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
• move the mantel
