You can easily change the flame height and accent lighting with the included multi-function thermostatic remote and wall-mounted LED lighting control to create the right mood in any situation. Choose from a variety of firebox liners, decorative trim kits, fire glass, and optional gas log media to make the design your own. The stainless-steel liner creates a bright, contemporary vibe, while the black porcelain liner reflects the flames for an exquisite and dramatic look. Choose from a plain black ¾-inch frame, a stylish matte black 1½-inch beveled front, or a seamless finish achieved by installing tile, stone, or plaster up to the fireplace opening. Barrier screens are included in the decorative fronts to prevent children and pets from coming into contact with the hot glass. The Empire Boulevard Ventless Linear Gas Fireplace - 72" comes with an electronic intermittent pilot ignition system and a battery backup for use in the event of a power outage. To obtain your ideal comfort level, use the multi-function thermostatic remote to manage the flame height with six flame settings and as a programmable room thermostat. To enjoy a fire, simply push the On/Off control, or use the Smart Thermostat function to set and maintain your chosen room temperature. For consistent warmth and minimized heat fluctuation around the room, the thermostat anticipates heat output and adjusts the flame height based on the difference between the programmed temperature and the actual temperature.
