4. Placement of Glowing Embers -
Separate the Embers (rockwool) into pieces
about the size of a quarter (see Figure 8).
Keep the pieces fluffed up, not matted. Dis-
tribute these pieces over the surface of the
burner, as shown in Figures 9 and 10. Do
not use more than is necessary. Ensure that
the main burner slots remain uncovered by
the ember material. Position the embers
on the small holes of the ember bed area.
Note: This appliance is provided with enough
Glowing Embers for several applications, do
not use all that is in a new bag at one time.
For best glowing effect, replace the ember
material annually.
5. Placement of Logs -
The logs have locating notches or slots to
help ensure that they are properly positioned.
The top logs that rest on lower logs, do so
over notches, indents or nubs. Proper log
placement is critical to prevent sooting.
Logs should be placed in the gaps between
the ame peaks and should be positioned
so they do not impinge the flames. Follow
the log placement instructions, exactly.
Volcanic Stone
Place Volcanic
Stone As Shown
INSTALL VOLCANIC STONE, GLOWING
EMBERS AND LOGS
NOTE: Turn off all electricity to the appliance
before you install volcanic stone, embers and
logs.
1. Remove the front glass enclosure panel
(see Removing Glass Enclosure Panels on
Page 11).
2. Always handle logs carefully to prevent
breakage.
3. Install decorative volcanic stone - Sprinkle
the decorative volcanic stone in a pleasing
pattern (see Figure 7). The volcanic stone
should be placed directly on top of the firebox
bottom, along the slope and to the back at
the right and left sides of the burner. Posi-
tion any ceramic fiber liners before placing
the stone. Logs can be positioned after the
volcanic stone.

WARNINGS
•
DO NOT attempt to install the
logs until the appliance instal-
lation has been completed, the
gas line connected and tested
for leaks and the initial burner
operation has been checked
out.
•
The size and position of the log
set was engineered to give the
appliance a safe, reliable and
attractive flame pattern. Any
attempt to use a different log
set in the fireplace will void
the warranty and will result in
incomplete combustion, soot-
ing, and poor flame quality.
•
Logs get very hot and will
remain hot up to one hour
after gas supply is turned off.
Handle only when logs are
cool. Turn off all electricity
to the appliance before you
install grate, volcanic stone,
vermiculite, embers and
logs.
•
This appliance is not designed
to burn wood. Any attempt to
do so could cause irreparable
damage to appliance and prove
hazardous to your safety.
•
If logs are not installed accord-
ing to the log installation
instructions, flame impinge-
ment and improper combus-
tion could occur and result in
soot and/or excessive produc-
tion of carbon monoxide (CO),
a colorless, odorless, toxic
gas.
