Minimum Noncombustible Material Clearances
If Not Using Mantel
Note: If using a mantel proceed to If Using Mantel. If not using
a mantel, follow these instructions.
You must have noncombustible material(s) above the replace
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 noncom-
bustible material is less than 12", you must install the replace
hood accessory (24" and 30" Models Only). See Figure 3 for
minimum clearances.
If Using Mantel
You must have noncombustible material(s) above the replace
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. Noncombus-
tible material must extend at least 8" up (for all models). If
noncombustible material is less than 12", you must install the
replace hood accessory. Even if noncombustible material is
more than 12", you may need the hood accessory to deect
heat away from your mantel shelf. See Figure 3 and Figures
4 and 5, page 6, for minimum clearances.
IMPORTANT: If you cannot meet these minimum clearances,
you must operate appliance with chimney ue damper open.
Go to Installing Damper Clamp Accessory for Vented Opera-
tion, page 7.
MANTEL CLEARANCES
In addition to meeting noncombustible material clearances,
you must also meet required clearances between replace
opening and mantel shelf. If you do not meet the clearances
listed below, you will need a hood.
Determining Minimum Mantel Clearance
If you meet minimum clearance between mantel shelf and
top of replace opening, a hood is not required (see Figure
