This specialized G45 Triple-T Vented Burner System accentuates the front flame and embers of the log set and is compatible with most of our log styles and controls. It produces the same realistic flames and natural look you would expect, but with a unique improvement. The Triple T features a T-shaped burner that emphasizes its front embers, giving them an even greater dramatic effect, and adds depth to its flames. This unique design also maximizes the warmth you get from your gas logs by bringing the flames closer to your fireplace opening. This is a vented gas log burner that must be installed in a fully vented wood burning fireplace. With vented gas logs, you'll enjoy a large, realistic-looking flame that operates with an open chimney flue, or damper. Vented Gas Log sets, which simulate a wood-burning fire, are the most realistic type of gas logs but, just like real fires, lose some of the generated heat up the chimney. Professional installation is recommended. Log sets sold separately.
