INSTALLING LOGS
CAUTION: After installa-
tion and periodically thereafter,
check to ensure that no ame
comes in contact with any log.
With the heater set to HI, check
to see if ames contact any log. If
so, reposition logs according to
the log installation instructions
in this manual. Flames contact-

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.

front log rests rmly between grate ngers 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
