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 fireplaceβno 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.
