Dimplex 86'' Opti-Myst Linear Built-In Electric Fireplace FAQ
How does the Opti-Myst water vapor flame technology work?
The Dimplex Opti-Myst system uses ultrasonic transducers to atomize water into an ultra-fine mist, which is then illuminated by HD LED lights to create the appearance of three-dimensional flames and rising smoke. The result is the most realistic electric flame effect on the market — visually indistinguishable from a real wood fire, and completely safe to touch since the vapor is cool.
Does this fireplace require a water connection?
Yes. The OLF86-AM is designed as a hard-plumbed built-in unit and connects directly to your home's water supply using standard 1/4" tubing for continuous operation. An optional plumbed water supply kit is available for copper piping installations, and a manual fill reservoir kit can be purchased separately if direct plumbing is not feasible.
What kind of heat output can I expect?
When wired to a 240V circuit, the concealed ceramic heater produces up to 6,551 BTUs and can warm rooms up to 1,000 square feet. Important: when connected to 120V, the OLF86-AM operates as a flame-only unit with no heat output. The flame effect can be enjoyed year-round independently of the heater.
Does the 86'' Opti-Myst Linear require venting or a chimney?
No. This is a zero-clearance built-in electric fireplace, meaning it requires no chimney, no gas line, and no venting of any kind. You simply need a properly framed opening (88" W x 31 3/4" H x 12" D), a dedicated electrical circuit, and a water supply connection.
How do I control the fireplace and customize the flames?
You have three control options: the included multi-function remote, the free Dimplex Flame Connect smartphone app (iOS and Android), and the hidden touch control panel built into the unit. Through these controls you can adjust flame intensity, brightness, color themes, timer settings, heater function, and sound effects. The Flame Connect App also lets you design custom flame profiles.
Is this fireplace suitable for commercial spaces like hotels and restaurants?
Yes. The Opti-Myst Linear's hard-plumbed continuous operation, premium build quality, and dramatic 86" linear flame display make it a popular choice for hotel lobbies, restaurants, retail showrooms, spas, and luxury hospitality projects. Its safe-to-touch cool-flame technology and zero-clearance install also make it ideal for high-traffic public settings.
What media is included, and can I customize the flame appearance?
The fireplace ships with two complete media sets — lifelike driftwood logs for a traditional look and modern acrylic ice crystals for a contemporary aesthetic. Adjustable spacers and slots allow you to customize the width, height, and pattern of the flames, while the 7 color themes (including Prism and Kaleidoscope) let you match the ambiance to any mood or décor.
What is the warranty and what's the shipping timeframe?
The Dimplex 86" Opti-Myst Linear comes with a 2-year manufacturer's limited warranty covering defects in materials and workmanship. Electric Fireplaces Depot offers free shipping throughout the continental USA on this unit, with typical delivery in 4–8 business days. A 30-day return policy applies to new, unused, unassembled items in original packaging.
