WARNING: After installation
and periodically thereafter, check
to ensure that no flame comes in
contact with any log. With the
heater set to High, check to see if
flames contact any log. If so, re-
position logs according to the
log installation instructions in this
manual. Flames contacting logs
will create soot.
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.
INSTALLING LOGS
It is very important to install the logs exactly
as instructed. Do not modify logs. Only use
logs supplied with heater.

ter of chassis (see Figure 24).

Make sure log does not
cover any burner ports.
CAUTION: Do not remove the
warning and instruction labels

sembly. These markings contain
