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. Locate pegs on the bottom of back log (#1).
Slide these pegs into the holes in the grate base
behind the burner (see Figure 18).
2. Locate the notches on the back of the front log
(#2). Slide these notches over the tabs of the
grate base (see Figure 19).
3. Locate the holes in the bottom of the left
crossover log (#3). Place crossover log on
pegs on left of the back log and front log (see
Figure 20, page 17).
4. Locate the holes in the bottom of the right
crossover log (#4). Place crossover log on
pegs on right of the back log and front log
(see Figure 20, page 17).
