Made for your space

Keep the hearth. Refine the finish.

A separately purchased black surround covers the gap between the insert and the existing fireplace opening. Choose the surround size after measuring the opening and checking the installation manual; the insert’s nominal size is not a substitute for those measurements.

Fuel & Compatibility

Choose the natural gas or liquid propane variant to match the installed supply. Fuel and ignition must be confirmed before ordering. Vent-free installation is subject to local requirements, room-size restrictions and the manufacturer’s instructions; a qualified installer must verify suitability.
