Unvented gas fireplaces
rely on complete burning of the gas. If the gas did not completely burn,
carbon monoxide would result. Incomplete combustion can be caused by
disturbing the flame with ceiling fans, open doors or windows that allow
a breeze to interfere with the flame and by moving or replacing the
ceramic logs with unapproved logs. Modifications to this type fireplace
can cause hazardous conditions to occur. You are advised to install a
carbon monoxide detector in the room with this unit. It is recommended
that you have the gas company check all appliances before taking
possession of the property and at least once every two years thereafter.
