Step 4. Wood mantel, shelf or combustible
projection requirements: To install a wood
mantel, shelf or other combustible projection
directly above the fireplace (firebox), refer to
Table 3
and to
Figures 4 and 5
for installation
profiles.
If your mantel profile is unsafe, you may either:
• Raise the mantel to an acceptable height, or
• Remove the mantel.
Example: The bottom of the mantel may project
from the wall a maximum of 2-1/2" at a mini-
mum of 28" above the opening. The top shelf of
the mantel may project a maximum of 6" at a
minimum of 34-1/2" above the opening.

Step 3. Noncombustible materials (minimum
requirements): To install the room heater with-
out wood mantels, shelves or other combus-
tible projections directly above the opening of
the fireplace (firebox) refer to
Figure 2
and
Table 2.
Note that at least 8" of noncombustible
material must be installed above the heaters
described in this manual.
Noncombustible materials, such as slate and
marble, must be at least 1/2" thick.

Follow these instructions carefully to ensure
safe installation. Failure to follow these require-
ments may create a fire hazard.
Step 1. Sidewall Clearances: The sides of the

combustible side wall (
Figure 1
).

Step 2. Ceiling Clearance: The ceiling must be
at least 42" from the top of the heater opening
(
