You must have noncombustible material(s)

be at least 1/2 inch thick. With sheet metal, you
must have noncombustible material behind
it. Noncombustible material must extend at
least 8" up (for all models). If noncombustible
material is less than 12", you must install the
fireplace hood accessory (for all models). See
Figure 5 for minimum clearances.

If Using Mantel
You must have noncombustible material(s)
above the fireplace opening. Noncombustible
materials (such as slate, marble, tile, etc.) must
be at least 1/2" thick. With sheet metal, you
must have noncombustible material behind it.
Noncombustible material must extend at least
8 inches up (for all models). If noncombustible
material is less than 12", you must install the
fireplace hood accessory (24" Models Only).
Even if noncombustible material is more than
12", you may need the hood accessory to
deflect heat away from your mantel shelf. See
Figure 5, and Figures 6 and 7 (page 11) for
minimum clearances.
IMPORTANT: If you cannot meet these mini-
mum clearances, you must operate heater
with chimney flue damper open. Go to Install-
ing Damper Clamp Accessory for Vented
Operation, page 11.
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).
