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. Noncombustible 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 deect 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 11.
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 be-
tween 8 inches and 12 inches above. If
you can not extend material, 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 5 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, thes 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 the following:
• Operate the logs with the ue damper open only.
• Raise the mantel to an acceptable height.
FLOOR CLEARANCES
a) If installing appliance on oor level, you must maintain
the minimum distance of 14 inches to combustibles
(see Figure 7).
b) If combustible materials are less than 14 inches to the
replace, you must install appliance at least 5 inches
above the combustible ooring (see Figure 8 ).
