 WARNING: Failure to position

the parts in accordance with these
diagrams or failure to use only
parts specifically approved with
this heater may result in property
damage or personal injury.

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 front logs (#1L and #1R) on top
of the grate. Make sure the notches in
the bottom of the logs fit over the grate
prongs (see Figure 16). Push back of
logs flush with metal grate bar. 

Note:

18" model has only one front log.

2.

Rest bottom middle log (#2) behind
metal posts on front burner. Make sure
the grooves in the bottom of the log fit
over the grate. Bring the log forward
next to the metal posts. The pegs on
the log must be on top (see Figure 17).

3.

Slide the grooves in the back of the rear
log (#3) against the rear grate prongs.
Make sure the peg on the log is on top
(see Figure 18).

4.

Place the top middle log (#4) on the
bottom middle log (#2). Make sure the
pegs of the bottom middle log fit se-
curely in the holes of the top middle
log (see Figure 19).

5.

Place the crossover log (#5) on the back
log and the top middle log. Make sure
the peg on the rear log is in the hole in
the bottom of the crossover log. The
crossover log should fit in the cutout
of the top middle log (see Figure 20).
