You must have noncombustible material(s) above the fireplace opening. Noncombustible materi- als (such as slate, marble, tile, etc..) Must be at least 1/2" thick. With sheet metal, you must have noncombustible material behind it. Noncombus- tible material must extend at least 8" up (for all models). If noncombustible material is less than 12", you must install the fireplace hood accessory (24" Models Only). See Figure 5 for minimum clearances.

Figure 5 - Heat Resistant Material (Slate,
Marble, Tile, etc.) Above Fireplace
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" 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 11, 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 12.
