The Empire Boulevard See-Through Direct Vent Fireplace - 48" is the ideal way to liven up your space, with a true 48-inch viewing area, completely recessed burner, and white LED lighting. As you relax by the fire, a dynamic flame presentation and 37,000 BTU heat output will keep you entertained and warm. You can monitor the flame height and accent lighting with the included multi-function thermostatic remote to create the perfect ambiance in any room. Install the Boulevard See-Through Direct Vent Fireplace - 48" in an interior wall to connect two rooms, or in an exterior wall with the optional indoor/outdoor kit to enjoy the fire from both inside and outside. Choose from a reflective black porcelain or Ledgestone firebox liner, decorative trim kits, and fire glass or gas log media to make the style your own. The black porcelain liner reflects the flames for an elegant and dramatic appearance, while the Ledgestone liner has a more rugged appearance. For a modern fire show, add crushed fire glass in the color of your choosing, or go with a gas log set for a traditional wood-fire feel. Barrier screens are used to keep children and pets from touching the hot glass. The Empire Boulevard See-Through Direct Vent Fireplace - 48" is equipped with an electronic intermittent ignition system and a battery backup for use in the event of a power failure. In colder weather, you can easily switch from intermittent ignition to standing pilot mode by using the remote control for fast lighting.
