INSTALLATION
Continued
NOTICE: Manual control heaters
may be used as a vented product.
If so, you must always run heater
with chimney flue damper open.
If running heater with damper
open, noncombustible material
above fireplace opening is not
needed. Go to
Installing Damper
Clamp Accessory for Vented
Operation
, page 12.
Minimum Noncombustible Material
Clearances
If Not Using Mantel
Note:
If using a mantel proceed to If Using
Mantel. If not using a mantel, follow the infor
-
mation on this page.
You must have noncombust ble material(s)
above the fireplace 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 fireplace hood accessory
(24" and 30" Models Only). See Figure 5 for
minimum clearances.
If Using Mantel
You must have noncombust ble material(s)
above the fireplace opening. Noncombustible
materials (such as slate, marble, tile, etc.)
must be at least 1/2" thick. With sheet metal,
you must have noncombustible material be-
hind it. Noncombustible material must extend
at least 8" up (for all models). If noncombus-
tible material is less than 12", you must install
the fireplace hood accessory (24" and 30"
Models Only). Even if noncombust ble mate-
rial is more than 12", you may need the hood
accessory to deflect heat away from your
mantel shelf. See Figure 5 and Figures 6 and
7, page 9, for minimum clearances.
IMPORTANT:
If you cannot meet these mini-
mum clearances, you must operate heater
with chimney flue damper open. Go to
Install-
ing Damper Clamp Accessory for Vented

12" or more
Noncombustible mate-
rial OK.
Between 8" and 12"
24", 30" or 36" Models:

to at least 8". See
Between 8" and 12"
,
above. If you cannot ex-
tend material, you must
operate heater with flue
damper open.
MANTEL CLEARANCES
In addition to meeting noncombustible mate-
rial clearances, you must also meet required
clearances between fireplace 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 man-
tel shelf and top of fireplace 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, page 11,
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.
