INSTALLATION
Continued
Figure 5 - Heat Resistant Material (Slate,
Marble, Tile, etc.) Above Fireplace
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 non-
combustible 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 replace hood accessory (24" and
30" models only). Even if noncombustible material
is more than 12", you may need the hood acces-
sory to deect 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
ue damper open. Go to Installing Damper Clamp
Accessory for Vented Operation, page 11.

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.
If you meet minimum clearance between mantel
shelf and top of replace opening, a hood is not
required (see Figure 6).
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 clearances shown in Figure 7,
page 11, when using hood.
