If Using Mantel
You must have noncombustible material(s)
above the fi replace opening. Noncombus-
tible materials (such as slate, marble, tile,
etc.) must be at least 1/2" thick. With sheet
metal, you must have noncombustible ma-
terial behind it. Noncombustible material
must extend at least 8" up (for all models). If
noncombustible material is less than 12", you
must install the fi replace hood accessory (24"
Model Only). Even if noncombustible material
is more than 12", you may need the hood ac-
cessory to defl ect heat away from your mantel
shelf. See
Figure 5
and
Figures 6 and 7,
Page 11
, for minimum clearances.
IMPORTANT:
If you cannot meet these
minimum clearances, you must operate
heater with chimney fl ue damper open. Go
to
Installing Damper Clamp Accessory for
Vented Operation

MANTEL CLEARANCES
In addition to meeting noncombustible mate-
rial clearances, you must also meet required
clearances between fi 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 fi replace opening, a
hood is not required
(see Figure 6).
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
, when using hood.
