INSTALLING LOGS
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.
CAUTION: After installation
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.

instructed. Do not modify logs. Only use logs
supplied with heater.
