The Vienna Difference — Technology That Sets It Apart

Most gas fireplaces require gaps, louvers, screens, and heat dumps that break up the clean look of your feature wall. The Vienna eliminates all of that. Its proprietary radiant thermal convection technology keeps all heat management contained within the firebox — allowing you to finish with combustible materials like wood framing and drywall directly around the fireplace with no concrete board or metal studs required. The result is a seamless, contemporary installation that looks like it was custom-designed for your space.

No Heat Dump — No vents required behind the wall to dump built-up heat — the Vienna manages it all internally.

Combustibles OK — Everything contained within the firebox means you can finish with wood, drywall, tile, or stone directly around the fireplace — no special fireproof board required.
