extend at least 8" up (for all models). If noncombustible material
is less than 12", you must install the fireplace hood accessory (24"

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 inch thick. With sheet metal, you must
have noncombustible material behind it. Noncombustible material
must extend at least 8 inches up (for all models). If noncombus-
tible 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 9, for minimum clearances.
IMPORTANT: If you cannot meet these minimum clearances, you
must operate heater with chimney flue damper open. Go to Installing
Damper Clamp Accessory for Vented Operation, page 10.
