Dimplex Opti-Myst 86-inch Linear Built-In Electric Fireplace (OLF86-AM)


The Optimyst® OLF86-AM delivers Dimplex’s ultra-real water-vapor flame effect in a statement-size 86-inch linear, complete with acrylic crystals and driftwood media. Designed for clean, built-in installs, it offers a broad 84-1/4" x 14-3/8" viewing area within 87-1/2" W x 31-1/2" H x 11-7/8" D overall dimensions for a slim, architectural look.

Day to day, choose flame-only ambience or on-demand Comfort$aver® supplemental heat. Electricals are project-friendly—120/240V hardwire with an optional 120V plug kit—delivering up to 2,400 W / 8,189 BTU on 240V (1020 W flame-only). Control is simple via the Flame Connect App, hidden touch controls, and the handheld remote.

Built for modern spaces, Optimyst runs without venting or gas lines and can connect to a continuous water supply for extended operation. It’s a premium focal point with the realism of fire, minus the hot glass and emissions.

(OLF86-AM is also known as 136809).
