INSTALLING LOGS
CAUTION: After installa-
tion and periodically thereafter,
check to ensure that no flame
comes in contact with any log.
With the heater set to HI, check
to see if flames contact any log. If
so, reposition logs according to
the log installation instructions
in this manual. Flames contact-
ing logs will create soot.
WARNING: Failure to posi-
tion 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 log (#1) on grate fingers. Make sure
front log rests firmly between grate fingers and
grate base (see Figure 18, page 16).
2. Place base of middle log (#2) in U-shaped
slots of grate base. The large cutout on bottom
right of middle log should fit over burner (see
Figure 19, page 16). Make sure front of middle
log is resting on tabs of grate base.
