Warning:
• It is recommended that the screen be used during operation of this log
set. Always ensure the screen has adequate spaces to allow for passage
of combustion air to the gas log set.
• Correct installation of the ceramic fiber logs, proper location of the
heater and periodic cleaning are necessary to avoid potential service
problems with sooting.
• Keep small children and animals away from the open flame of the gas
log set at all times.
• There may be a start-up odor associated with the heating of the logs.
The odor should diminish in 2-3 hours of operation with the burner at its
highest setting with the fan in the off position.
