SETUP
Your Comfort Glow Patio Fire is designed
to operate with lava rock piled in and around
the burner, and refractory logs placed on top
of the lava rock.
Carefully pour supplied lava rock into basin
to cover the burner. Be sure that the burner
and burner ports are covered completely by
lava rock to better disperse the flame and to
create a more natural looking fire.
Place the six refractory logs on top of the
lava rock. The arrangement is left to your
personal preference. Try different place-
ments to achieve your desired flame pattern.
Note: Sooting on the logs is natural. You
may clean with a soft bristle brush.
CAUTION: Place lava rock
carefully. Be careful not to dam-
age the burner, ignitor electrode,
or thermocouple when adding the
lava rock.
WARNING: Allow logs and
lava rock to cool completely be-
fore handling or rearranging logs.

trol panel (see Figure 6).
2. Rotate the ignitor button counterclock-
wise to remove.
3. Install a fresh AA alkaline battery into
the ignitor module, positive terminal
