Abstract
A realistic gas fire log system providing log movement during use to enhance the realism of a fireplace system, comprising a ceramic fiber top, molded to look like charred embers or ash ported with one or more holes and recessed at the bottom to form a cavity, a steel pan sealed to the bottom of the ceramic fiber top, forming a chamber; a gas supply, gas control valve and a venturi fitted in an orifice through the pan, and including a log movement mechanism comprising an armature for pivotable attachment to one end of a fire log resting over a second fire log including two or more log sections connected by a spring and an activating mechanism, which armature causes the hinged log to collapse downwardly when activated and reposition into its original position when the fireplace is turned off. The log movement mechanism can be incorporated into existing gas fire log systems or made part of the original equipment of a gas fire log system.
