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 installa-
tion 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, reposition logs according to
the log installation instructions
in this manual. Flames contact-
ing logs will create soot.
It is very important to install the logs exactly as
instructed. Do not modify logs. Only use logs
supplied with heater.
1. Place bottom log (#1) on grate to fit as illustrated
in Figure 18. Make sure open areas of log set line
up with burner ports (see Figure 19). Log will fit
securely on chassis. IMPORTANT: Make sure
log does not cover any burner ports.
2. Facing front of unit, place top log (#2) onto
the pegs in the center of the bottom log (see
Figure 20).
