Log Placement
Carefully position the ceramic fiber logs and
twigs over the burner as shown in
Figure 6
.
Refer to the detailed log placement instruc-
tions provided in the LOG PLACEMENT GUIDE
accompanying this document.
Proper twig placement is critical to prevent
sooting. Twigs should be placed in the gaps
between the flame peaks and should be posi-
tioned so that at no time they impinge the
flames.
Rockwool (Glowing Embers) Placement
Remove the replacement rockwool from the
packaging and tear into nickel size pieces
(
Figure 7
). Spread on and along the length of
the front burner section. Do not use more than
is necessary. Too many nickle-sized pieces on
the front burner section will cause poor com-
bustion.
When properly positioned, the rockwool will
unevenly cover approximately 65% of the front
burner with no appreciable gaps or openings.
Do not
place ember materials over large ports
- refer to the
LOG PLACEMENT GUIDE
.

With proper care and maintenance, your appli-
ance will provide many years of enjoyment. If you
should experience any problem, first refer to the
trouble shooting guide in this manual. If problem
persists, contact your Lennox distributor.
Vermiculite Placement
Mound up a portion of the vermiculite (with a
mixture of black and gray ceramic fiber chunks)
in front of burner and grate. Taper off mound to
the front and at the sides. Spread the remaining
vermiculite evenly over the bottom surface of
the appliance firebox bottom plate as desired
to achieve an esthetically pleasing appearance.
For best results, spread in a non-uniform man-
ner while ensuring complete coverage of the
tan sheetmetal surface.
