Abstract
A novel control system for altering a fixed pattern of gas flames in a fireplace having artificial logs comprises a log set having a burner system and the burner system having a gas valve control which is coupled to source of gas or air to be regulated. The control system has a valve which controls the air or gas being supplied to the burner and a control sensor is coupled to the control system for activating the time sequence of the cycle of the control system so as to raise or lower the gas flames being regulated and to disturb the pattern of gas flames to produce the effect of dancing flames.
