Empire Keystone Deluxe B-Vent Fireplace, 34-Inch Flush Face

The Empire Keystone Deluxe B-Vent Fireplace ships with a 34-inch viewing area — wide enough to make a room take notice, proportioned well enough to fit a realistic rough framing width of 37.38 inches. At 21,000 BTU on natural gas with millivolt ignition, it produces real, reliable heat without requiring a dedicated electrical circuit to get the flame going. That independence from household power is a quiet but meaningful advantage for a hearth product meant to be used on cold nights.

B-vent design means this fireplace draws combustion air from the room and exhausts directly up through a 4-inch inner-diameter chimney — a straightforward, time-tested approach that keeps installation logic simple. Top-vent-only configuration directs the entire venting path upward, so placement flexibility is determined by your ceiling and chimney layout rather than by complicated horizontal routing.

Zero clearance to combustibles on the back, sides, and floor gives builders and remodelers genuine flexibility when framing. The only clearance requirement to keep in mind is 12 inches above the unit. Overall dimensions come in at 37 inches wide at the front, 24.5 inches at the rear, 14.87 inches deep, and 32.68 inches tall — precise numbers worth handing directly to your contractor rather than approximating.

The flush face profile keeps the front plane clean and uninterrupted, which suits modern and transitional interiors equally well. One trade-off worth knowing upfront: flush face models do not have blower options available. If forced-air circulation is a priority for your installation, that's a compatibility note to factor in before purchase.

Out of the box, the Keystone Deluxe includes a log set, a junction box, and an operable curtain screen — practical inclusions that reduce the immediate accessory list considerably. For those who want to dress the surround further, optional decorative louvers, doors, and frames are available separately, as is the glass door model BVX2BL for a more enclosed look.

At 75 pounds, this is a unit that two people can handle during installation without requiring heavy equipment. The 35.75-inch rough framing height and 14.38-inch rough framing depth are the numbers your framer will want — clean, buildable dimensions for a fireplace that's designed to slot into a wall and stay there for years.
