Proper log placement is critical to prevent soot-
ing. Carefully position the ceramic fiber logs
over the burner as described in the following
steps, and detailed in Figures 18 through 23.
NOTE: Logs should be placed in the gaps be-
tween the flame peaks and should be positioned
so that at no time they impinge the flames.
Step 1. Remove the glowing embers (rock-
wool) from the packaging and tear into nickel
size pieces. Spread the glowing embers evenly
on top of the burner. Do not use more than is
necessary. The glowing embers should not
cover the burner ports, as shown in Figure 18.
Step 2. Place the hole at the bottom of the Rear
Log over the pin at the rear of the log grate, as
shown in Figure 19. The log should rest against
the back refractory.
Step 3. Place the Rear Top Log over the left side
of the Rear Log. Lay the log over the top left
corner of the Rear Log, as shown in Figure 20.
The log should rest against the back refractory.
Step 4. Engage the bottom hole of the Front
Left Log with designated pin on the grate, and
align the bottom groove of the log over the far
left grate bar. See Figure 21.
Step 5. Engage the bottom hole of the Front
Right Log with designated pin on the far right
grate bar. Align the groove on the bottom of the
log over the far right grate bar. See Figure 22.
Step 6. Engage the bottom hole of the Top
Right Log, over the pin on the Front Right Log.
Rest the upper portion of the log in the notch
of the Rear Log. See Figure 23.
