For Fully Recessed Installation, it requires Tile or other non-combustible material to fireplace opening (Wall must be 2 x 6 framing or deeper)
At just 5-1/2" inches deep the Boulevard SL is the first vent-free fireplace that can install fully in a 2X6 stud-framed wall. Add tile right up to the rectangular opening to create a stunningly beautiful, amazingly efficient clean-face fireplace. The optional narrow trim kit finishes the opening and adjusts for different depths of tile or stone. Recessed installation requires installing the included noncombustible material above and to the sides of the fireplace and tile or stone to the fireplace opening. The optional narrow trim kit hides tile edges and adjusts from 1/2 to 1 inch.
