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 deect
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
