Requirements for Safe
Installation
12" or more Noncombustible material
okay.
Between 8"
and 12"
24" Models: Install replace
hood accessory (GA6050 or
GA6053 see Accessories,
page 30).
18" Model: Noncombustible
material okay.
Less than 8"
Noncombustible material
must be extended to at least
8". See Between 8" and 12",
above. If you cannot extend
material, you must operate
heater with ue damper open.
MANTEL CLEARANCES
In addition to meeting noncombustible mate-
rial clearances, you must also meet required
clearances between replace opening and
mantel shelf. If you do not meet the clearances
in Figure 6, page 11 you will need a hood.
Determining Minimum Mantel Clearance
If you meet minimum clearance between man-
tel shelf and top of replace opening, a hood
is not required (see Figure 6, page 11).
Determining Minimum Mantel Clearance
When Using a Hood
If minimum clearances in Figure 6 are not
met, you must have a hood. When using a
hood there are still certain minimum mantel
clearances required. Follow minimum clear-
ances shown in Figure 7, page 11 when
using hood.
