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 these logs exactly
as instructed. Do not modify logs. Only use
logs supplied with heater.

Cutout on front right will fit over burner
(see Figure 17). Make sure back of log
assembly is resting on back tabs of base.
There are 2 small notches on log that fit
onto front tabs.
2. Place front log onto grate. Log is notched
to sit over grate (see Figure 18, page
16). Position holes on bottom of log over
shoulder screws on base.
3. Place crossover log onto pins on main log
and front log (see Figure 19, page 16).
Note: Nontextured end of crossover log
faces back of firebox and will not be seen
