White Mountain Hearth Vail 36 Premium Vent-Free Fireplace, 36,000 BTU

The White Mountain Hearth Vail 36 Premium is built around a single, difficult-to-argue-with number: 99.9% efficiency. Every BTU generated by its 30-inch Slope Glaze burner stays in the room rather than heading up a flue that, notably, this unit doesn't require. Vent-free installation means no chimney, no chase, no expensive liner work — just a framed opening (46 3/8" W × 42 5/16" H × 18 3/4" D) and a gas line.

The firebox itself measures 40 1/2" wide by 35 3/4" tall by 19" deep, presenting a generous 36" × 24 1/4" viewing area — enough real estate that the fire reads as a proper architectural focal point rather than a polite decorative gesture. Zero-clearance construction keeps the installation footprint honest and the framing straightforward.

Ignition is millivolt standing pilot, which means the fireplace operates independently of household electricity. No power outage is going to take away your heat source on the one night you actually need it.

Heat output runs between 25,000 and 36,000 BTU/hr, giving you a meaningful range to work with rather than a single fixed setting. Natural gas inlet pressure requirements are 4.5 inches WC minimum and 14 inches WC maximum.

Out of the box, the Vail 36 Premium includes a matte black hood, outer frame, arched screen front, and slat louvers — a cohesive, finished look that doesn't demand additional purchases just to look presentable. That said, the customization options are extensive. Log sets in ceramic fiber or refractory in 30-inch sizing are compatible, and five distinct brick liner styles are available — aged brick, stacked limestone, traditional, banded brick, and black porcelain — so the firebox interior can align with the surrounding room's character rather than contradict it.

For control preferences, the Vail 36 accepts an impressive roster of optional remote and wall control systems: the FRBC On/Off remote, FRBTC Thermostat remote, FREC Electric remote, FRBTP Programmable remote, FWS1 Wall Switch, TMV Reed Switch, TRW Wireless remote, and TDV1 Wall Thermostat. Optional blower systems, door sets, door frames, additional outer frames, bottom trim kits, and cabinet mantels round out the accessory catalog.

At 111 lbs (104 lbs item weight), the Vail 36 is a substantial unit that installs with confidence. The finish is black. The efficiency is 99.9%. The customization path is genuinely wide. If your project calls for a serious vent-free firebox with room to grow, this is a well-considered starting point.
