The Empire Whiskey River Ventless Gas Log Set includes ultra-realistic, hefty logs with a ton of hand-painted detail. The Whiskey River collection adds rich warmth and dramatic character to any room. This log set is suitable for both existing and new fireplaces and fireboxes. The burner that comes with these logs has a precision-ported tube that gives it a fantastic appearance! It's a little system that will fit in a firebox that's at least 12" deep. By opening the flue damper in your fireplace, you may easily change this system to a vented version.
