Air Shutter Adjustment Guidelines:
If the burner fl ame appearance differs greatly
from what is shown on Page 6 (see Burner
Flame Appearance), some adjustment from
the factory setting for the air shutter gap may
be necessary (to compensate for variables in
the installation and fuel such as, BTU value /
composition, gas pressure, specifi c gravity
of gas, altitude, etc.).
Table 6 is provided to aid you in achieving
the correct air shutter adjustment for your
installation.
When satisfi ed that the appliance operates
properly, proceed to fi nish the installation.
Leave the control knob in the ON position
and the ON/OFF switch in the OFF position.
Close the lower access door.

WARNING
Logs get very hot and will remain
hot up to one hour after gas
supply is turned off. Handle
only when logs are cool. Turn
off all electricity to the appliance
before you install logs.
WARNING
This appliance is not meant to
burn wood. Any attempt to do so
could cause irreparable damage
to your appliance and prove
hazardous to your safety.
WARNING
The size and position on the
log set was engineered to give
your appliance a safe, reliable
and attractive fl ame pattern.
Any attempt to use a different
log set in the stove will void
the Warranty and will result in
incomplete combustion, soot-
ing, and poor fl ame quality.
WARNING
If logs are not installed accord-
ing to the directions shown
here, fl ame impingement and
improper combustion could
occur and result in soot and/or
excessive production of carbon
monoxide (CO), a colorless,
odorless, toxic gas.
