Dimplex 46" Optimyst Linear Electric Fireplace FAQ
How does the Optimyst® flame effect work?
The Dimplex Optimyst® uses patented ultrasonic technology to atomize water into an ultra-fine mist, which is then illuminated by advanced multicolor LED lighting. The combination produces the appearance of three-dimensional flames and rising smoke without generating any actual fire, heat from the flames, or emissions—delivering the most realistic electric flame effect on the market.
Does the OLF46-AM require a water connection?
The fireplace can be operated two ways: by filling the integrated refillable reservoir for plug-and-play use, or by connecting it directly to your home's main water line for continuous, uninterrupted operation. An optional Dimplex plumbing kit is available for hardline installations, making this unit ideal for both residential homes and commercial hospitality settings.
How much heat does this fireplace produce?
The concealed ceramic heater is rated at 1,220 watts on a 120V circuit (4,163 BTU) and can warm spaces up to 500 sq ft. When wired to a 240V circuit, it operates at 1,920 watts (6,551 BTU) and provides supplemental heat for areas up to 1,000 sq ft. The flame effect can also be operated independently of the heater for year-round ambiance.
Can this fireplace be installed in a corner or recessed wall application?
Yes. The Optimyst® Linear is designed with four flexible installation options: front-facing, left-corner, right-corner, and bay configurations. Its zero-clearance firebox and slim 11.8" depth allow it to be fully recessed into a wall or framed structure, giving designers and homeowners complete flexibility for any architectural layout.
Is the Dimplex OLF46-AM safe for homes with children and pets?
Absolutely. Because the flame effect is produced by water vapor and LED light rather than actual combustion, the flames themselves generate no heat and the front glass stays cool to the touch. The heater is fully concealed and includes automatic shut-off protection, making this one of the safest fireplace options available for families.
Can I control the fireplace remotely with my phone?
Yes. The Optimyst® Linear is Wi-Fi enabled and pairs with the free Dimplex Flame Connect App, allowing you to control flame intensity, color themes, heat settings, timer functions, and custom mood scenes from anywhere. The unit also includes a multi-function remote control and hidden touch controls on the unit itself.
What media is included with the fireplace?
Each Dimplex 46" Optimyst® Linear ships complete with realistic Driftwood logs and Acrylic Ice media for layering effects on the fuel bed. Adjustable flame spacers are also included so you can customize the width and shape of the vapor flames to suit your installation.
What is the warranty on the Dimplex OLF46-AM?
The Dimplex Optimyst® Linear Electric Fireplace is backed by a 2-Year Limited Manufacturer Warranty covering defects in materials and workmanship under normal residential use. Built-in Smart Self-Diagnostic technology also helps simplify troubleshooting and service should any issue arise during ownership.
