Create a remarkably realistic built-in fireplace with the Dimplex 3 Step Multi RGB Optimyst Electric Fire. Designed for one-, two- or three-sided installation, this versatile frameless appliance can be configured as a streamlined front-facing fire, a corner fire with one exposed side or an impressive panoramic centrepiece with both side windows visible. Its patented Optimyst technology combines illuminated water vapour with multicolour LED lighting to create three-dimensional flames and smoke that appear to rise naturally between the logs. Realistic Optimyst Flames Unlike a conventional screen or projected flame effect, Optimyst uses an ultra-fine mist of water and carefully positioned lighting to create the illusion of real flames and smoke. The floating effect has genuine depth and can be viewed from several angles, making it particularly effective when the fire is installed with one or both side windows exposed. Multicolour RGB Flame Lighting Personalise the display using the Dimplex Flame Connect App. Choose from blue, violet, red and aquamarine flame colours or select a mixed multicolour effect. The flame intensity can also be adjusted, allowing you to create a subtle background glow or a more prominent and colourful fireplace display. One, Two or Three-Sided Installation The 3 Step Multi can be incorporated into several different wall designs. Install it as a one-sided fire for a clean front-facing appearance, expose either side for a corner installation or reveal both sides to create a panoramic three-sided focal point. Its frameless construction allows the surrounding wall finish to meet the appliance closely, creating a bespoke built-in appearance. Realistic Log Display A detailed log set is supplied as standard and sits among the illuminated water-vapour flames. The combination of three-dimensional mist, multicolour lighting and realistic logs creates a convincing fireside scene without producing real smoke, ash or combustion gases. Crackling Fire Sounds Integrated wood-crackling sound effects add another layer of realism to the display. The sound can be enjoyed alongside the flames or turned off when a quieter atmosphere is preferred. Flame Connect App and Remote Control The Dimplex Flame Connect App provides comprehensive control over the flame colours, intensity, sound and heating functions from a compatible smartphone. A multifunction remote control is also included, while manual controls built into the appliance provide access to essential functions. Convenient Front-Fill Water Drawer The water reservoir is accessed through a discreet drawer at the front of the fire, making routine refilling straightforward after installation. Because the reservoir can be reached from the front, the appliance does not normally need to be removed from its enclosure for everyday water filling. Comfort$aver Heating The integrated 900W heater provides supplementary warmth when required. Dimplex Comfort$aver technology helps maintain a consistent room temperature while reducing unnecessary heater operation. A seven-day programmable timer allows the heating schedule to be planned around your regular routine. The flame effect can be operated without heat, allowing the fire to provide atmosphere throughout the year. Installation and Ventilation The 3 Step Multi is designed for permanent installation within a suitably constructed feature wall or chimney-breast structure. Adequate airflow is essential for the Optimyst flame effect and heater to operate correctly. The required air inlets, construction opening, electrical provision and installation clearances must be incorporated in accordance with the current Dimplex installation instructions.
