Heat Resistant
Material
If Using Mantel
You must have noncombustible material(s) (such as slate, marble, tile, etc.) at least 1/2
in. thick. With sheet metal, you must have noncombustible material behind it. Noncom-
bustible material must extend at least 8 inches up. If noncombustible material is less than
12 in., you must install the replace hood accessory. Even if noncombustible material is
more than 12 in., you may need the hood accessory to deect heat away from mantel
shelf. See Figures 4, 5 and 6 for minimum clearances requirements.
IMPORTANT: If these minimum clearances are not met, you must operate heater
with chimney ue damper open. Go to “Installing Damper Clamp Accessory for
Vented Operation,” page 13.
Noncombustible
Material Distance
Requirements for
Safe Installation
8 inches or more Noncombustible material
okay.
Less than 8 inches Noncombustible material
must be extended to at least
8 inches. See between 8
inches and
12 inches above.
If you can not extend mate-
rial, you must operate heater
with ue damper open.
MANTEL CLEARANCES
In addition to meeting noncombustible
material clearances, you must also
meet required clearances between
replace opening and mantel shelf.
If the clearances listed below are
not met, you will need a hood.
Determining Mantel Clearances
If you meet minimum clearance
requirements between mantel
shelf and top of replace opening,
a hood is not necessary
(see Figure 5).
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 clearances shown in Figure
6 when using a hood.
NOTICE: Surface temperature
of adjacent walls and mantels
become hot during operation. Walls and
mantels above the rebox may become too
hot to touch. If installed properly, these
temperatures meet the requirement of
the national product standard. Follow
all minimum clearances shown in this manual.
NOTICE: If your installation does not meet the
minimum clearances shown, you must do one of
t
he following: Operate the logs with the ue
damper open only. Raise the mantel to an
acceptable height.
