L3 Gas Fireplace

The L3 is Valor's largest linear gas fireplace. At 66 ¼ inches, the L3 is noticeably wider than the L2 and features the newly introduced birch log and stacked stone liner media options. Due to its highly efficient design, the L3 utilizes standard 6 ⅝" ventilation systems making it a practical option with a simple installation.

The Valor HeatShift System™ is highly recommended for installations where surrounding structural areas must remain at cooler temperatures.
