The Sierra Flame Vienna 40" is a single-sided linear direct vent gas fireplace with a clean, frameless look: no louvers, no screens and no gap above the opening. Fans pull room air through a double glass channel and push the warmed air back into the room, which keeps the front glass cool enough to run without a mesh barrier. It frames in wood and you can finish combustible material right up to the fireplace. The Vienna also comes in 50" and 60" widths.
Key Features
- Double glass front with fans moving room air through the glass channel, so there is no mesh safety screen; the fans must run whenever the fireplace is on
- 3 variable speed fans (110 V), adjusted from the remote
- Electronic pilot ignition with a hand-held remote
- All-wood framing; combustible finishes allowed around the fireplace
- Inside of the glass can be cleaned without a service call
- Ships natural gas; propane by conversion kit
