The Sierra Flame Vienna Linear Gas Fireplace is a refined, single-sided gas fireplace designed for modern interiors where clean lines, seamless finishes, and architectural precision matter. With no louvers, no screens, no gaps, and no heat dumps, the Vienna Series delivers an uninterrupted flame view that integrates beautifully into contemporary living spaces, including condominiums.

Unlike traditional gas fireplaces that require visible vents or non-combustible surrounds, the Vienna features fully contained firebox technology. This allows you to finish directly with drywall or wood around the fireplace—no concrete board or metal studs required. Its double-wall glass system eliminates the need for a safety screen while keeping the glass warm to the touch and easy to maintain.

Available in multiple sizes and compatible with Natural Gas or Liquid Propane, the Vienna offers a balance of elegant design, efficient performance, and simplified installation for modern residential projects.

Frequently Asked Questions

Is the Vienna suitable for a condo installation?

Yes, Sierra Flame specifically lists the Vienna as condominium-suitable, though you should still confirm venting requirements against your building's specific code before ordering.

What rough opening do I need for each Vienna size?

Frame to 36.5" H x 43.25" W x 18.5" D for the 40", 36.5" H x 51.25" W x 18.5" D for the 50", and 36.5" H x 61.25" W x 18.5" D for the 60". These are the manufacturer's framing dimensions, not the visible glass area.

Is the Vienna available in propane, or natural gas only?

Both. Every size is offered in natural gas or liquid propane, so choose the fuel variant that matches your home's supply at checkout.

Can I finish the surround with wood or drywall right up to the firebox?

Yes, the fully contained firebox is rated for combustible materials like wood framing and drywall directly around it, with no concrete board or metal studs needed.

Is a vent termination kit included?

No, the termination kits and Duravent through-the-roof kits (standard or steep) are optional accessories sold separately based on your venting run.

Does the glass need a safety screen?

No. The double-wall glass system keeps the exterior surface warm rather than hot, which is what lets Sierra Flame skip the safety screen while still keeping the glass touch-safe.
