The SYMMETRY fireplaces have been made with standardized unit sizing.
Standardized fireplace sizing creates hassle-free installation at any stage of the project. This means that the opening for the fireplace can be made at any stage of a build – the appliance can be easily installed and finished with the included surround at the end of a project. The surround beautifully completes the fireplace without the need for detailed or costly finishing.
Clean Face

You’ll see more of what is important – a beautiful, warm and comforting flame display.
