The present invention produces a combustion simulation of flames, burning logs and embers in a fuel-burning fireplace or like device. One or more light source(s), such as LEDs, are used to transmit light to and through: a flame cut-out panel or flame cut-out mask to simulate the flame effect; cut-outs in logs to simulate a burning edge of a log; elements or refractories that refract the light to simulate real burning embers. Fiber optic cables, or any other material that facilitates the transmission of light, may be used to assist in transmitting the visible light. A motor driven rotating disk that includes apertures may be used to fragment the transmission of the visible light. In addition, the light source may be controlled by a sequencing device to closely approximate the pulsing intensities of light seen in actual flames, the edges of burning logs, and ember beds.
