Amantii Signature 38-Inch Built-In Electric Fireplace with Optimyst

Product Description

The Amantii Signature 38 brings the Dimplex Optimyst water-vapor flame into a built-in electric fireplace sized for a 38-inch opening. A fine mist rises through the log set and glass media and catches the light, so the flames appear to flicker and curl above the bed while the unit runs on electricity alone, with no gas line and no venting.

The Signature frames into a wall for a flush, built-in look, finished with mirrored black glass side liners, a six-piece lit log set, and decorative glass media in the carton. It wires to a standard 120V circuit for the flame effect, or to a 240V circuit when you want supplemental heat, and a licensed electrician should confirm the circuit before installation.

A multi-function thermostatic remote, the onboard controls, and the Amantii mobile app manage the flame, the multi-color LED lighting, the ember bed colors, and the heat. Per Amantii, the Signature 38 warms up to 400 square feet and delivers about 5,000 BTU. The Dimplex Optimyst cassette holds a refillable water container for the vapor effect, and batteries for the remote are not included.
