Product Description

Dull, artificial-looking flames can take away from the comfort and appeal of a fireplace. A burner system that delivers lively, natural flame movement can completely transform the atmosphere of your space.

Designed for use with compatible vent-free gas log sets, this burner system offers flexible ignition options, adjustable flame height, and enhanced safety features.

With built-in safety controls, realistic ember presentation, and dependable heat output, the Natural Blaze burner is an ideal foundation for creating a lifelike gas fireplace experience.
