CAUTION: After installation
and periodically thereafter, check
to ensure that no flame comes in
contact with any log. With the
heater set to HIGH, check to see
if flames contact any log. If so,
reposition logs according to the
log installation instructions in this
manual. Flames contacting logs
will create soot.
Each log is marked with a number. These
numbers will help you identify the log when
installing. It is very important to install these
logs exactly as instructed. Do not modify
logs. Only use logs supplied with heater.
1. Place the base of the middle log (#1) in
the U-shaped slots of the grate base.
The cutout on the right of the middle
log should bit over the burner (see Fig-
ure 25). Make sure the front of the
middle log is resting on the tabs of the
grate base and the cutout area is cen-
tered over the burner “U” bend.
2. Locate pegs on the bottom of back log (#2).
Slide these pegs into the holes in the grate
base behind the burner (see Figure 26).
3. Place cross-over log (#3) onto the pin
(right) on middle log (#1) and into the re-
cess of the back log (#2) (see Figure 27).
4. Locate the notches in the bottom of the
front log (#4). Place the front log on
the grate fingers. Make sure the notches
of the front log line up with the grate
fingers (see Figure 28).
5. With knot to right side, place smaller
log piece (#5) over the pin on the lift
side of the middle log. The smaller log
will rest on front log against the “knot”
on the left (see Figure 29, page 15).
6. Add lava rock around base of heater. Do
not place any lava rock on logs or burner.

log. Make sure the notches of the cross-
over log lines up with rectangular knobs
on top of the middle and front logs (see
Figure 24).
5. Add lava rock around base of heater. Do
