Minimum Non-Combustible 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 non-combustible material(s) above the fireplace opening. Non-combus- tible materials (such as slate, marble, tile, etc.) must be at least 1/2 inch thick. With sheet metal, you must have non-combus- tible material behind it. Non-combustible material must extend at least 8" up (for all models). If non-combustible material is less than 12", you must install the fireplace hood accessory (24" and 30" models only). See Figure 5 for minimum clearances.

IMPORTANT: If you cannot meet these minimum clearances, you must operate heater with chimney flue damper open.

If Using Mantel

You must have non-combustible material(s) above the fireplace opening. Non-combus- tible materials (such as slate, marble, tile, etc.) must be at least 1/2 inch thick. With sheet metal, you must have non-combus- tible material behind it. Non-combustible material must extend at least 8 inches up (for all models). If non-combustible material is less than 12", you must install the fireplace hood accessory (24" and 30" models only). Even if non-combustible 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 7on page 9 for minimum clearances.

IMPORTANT: If you cannot meet these minimum clearances, you must operate heater with chimney flue damper open.
