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" 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. Go to Install-
ing Damper Clamp Accessory for Vented Operation, 
page 10.

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 noncombustible
material is less than 12", you must install the fireplace hood
accessory (24" and 30" 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 on page 9 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.

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
