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 11 through 15.
Note: Logs should be placed in the gaps between
the flame peaks and should be positioned so
that at no time they impinge the flames.
Step 1. Remove the rockwool from the pack-
aging and tear into nickel size pieces. Spread
the rockwool evenly on top of the burner. Do
not use more than is necessary. The rockwool
should not cover the burner ports, as shown
in Figure 10.
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 11. 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 12. The log should rest against the
back refractory.
