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 22). 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 23).

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 24).

4. Place the top middle log (#4) on the bottom middle log (#2). Make sure the pegs of the

bottom middle log fit securely in the holes of the top middle log (see Figure 25).
