ally-controlled models] or pages 18 through 20 [thermostati-
cally-controlled models]). Check all other internal joints for leaks.

INSTALLING LOGS

CAUTION: After installation and periodically there-
after, 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 ac-
cording to the log installation instructions in this
manual. Flames contacting logs will create soot.
