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.
