NOTICE: Manual control heaters may be used as a vented product. If so, you must always run heater with chimney flue damper open. If running heater with damper open, noncombustible material above fire- place opening is not needed. Go to Installing Damper Clamp Accessory for Vented Operation, page 10.
Minimum Noncombustible Material Clearances
If Not Using Mantel
Note: If using a mantel, proceed to If Using Mantel. If not using a mantel, follow the information below.
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" up (for all models). If noncombustible material is less than 12", you must install the fireplace hood accessory (24" model only). See Figure 5 at right for minimum clearances.
IMPORTANT: If you cannot meet these minimum clearances, you must operate heater with chimney flue damper open. Go to Install- ing Damper Clamp Accessory for Vented Operation, page 10.

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" model 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 on page 9 for minimum clearances.
