CAUTION: The fireplace in which the Optima 3 INS is to be installed must be thoroughly cleaned if it has been used to burn wood or synthetic logs. Have the chimney and all inside sur- faces of the fireplace brushed and vacuumed so that no soot, embers, or loose combustion deposits can be drawn into the heat circulation blower and blown into the living area. If any por- tion of the chimney system shows signs of structural or me- chanical weaknesses, such as: cracks, leaky joints, corroded or warped surfaces, the faulty portion must be repaired or replaced prior to installing this appliance.
IMPORTANT: When installing the Optima 3 INS into a factory built fireplace or heatform, the air flow within and around the fire- place shall not be altered by the installation of the insert (i.e. DO NOT BLOCK louvers or cooling air inlet or outlet ports, circulating air chambers in a steel fireplace liner or metal heat circulator). The factory built firebox must accept the insert without modification other than removing bolted or screwed together pieces such as smoke shelf / deflectors, ash lips, screen or door tracks and damper assemblies. Any fireplace component, which is removed, must be retained so they can be reinstalled to restore the fireplace to its original operating condition. The removal of any part must not alter the integrity of the outer shell of the
