Step 8. INSTALL VERMICULITE, VOL-
CANIC STONE, GLOWING EMBERS AND
LOGS
1. Remove the front glass enclosure panel
(see
Removing Glass Enclosure Panels on
Page 31).
2. Remove log set box from firebox. Next,
remove embers and vermiculite from control
compartment.
Handle logs carefully to prevent
breakage.
3. Install Vermiculite - Place some vermiculite
on the firebox floor around the burner (the
entire bag of vermiculite will NOT be used).
See
Figures 55 & 56. DO NOT PLACE ANY
VERMICULITE ON THE BURNER. Mound
up a portion of the vermiculite in front of the
burner.
4. Install decorative volcanic stone - Sprinkle
the decorative volcanic stone (dark colored)
on top of the vermiculite (light colored) in a
pleasing pattern (see
Figures 55 & 56).
5. Placement of Glowing Embers -
Separate the Embers (rockwool) into pieces
about the size of a quarter (see
Figure 54).
Keep the pieces fluffed up, not matted. Dis
-
tribute these pieces over the surface of the
burner, as shown in
Figures 55 & 56. Do not
use more than is necessary. Ensure that the
main burner slots remain uncovered by the
ember material.
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.
6. Placement of Logs and Twigs -
All logs that have locating notches or slots to help
ensure that they are properly positioned. All top
logs that rest on lower logs, do so over notches,
indents or pins. Proper twig placement is critical
to prevent sooting. Twigs should be placed in
the gaps between the flame peaks and should be
positioned so they do not impinge the flames.
