Product Overview
The Amantii Symmetry Lumina 100 creates a broad, contemporary fireplace focal point while preserving the convenience of electric operation. Its slim linear body can be recessed into a framed wall opening or mounted on a suitable wall, allowing it to work in both new construction and renovation projects.
The fireplace includes separate controls for the flame display, ember bed, mood lighting, heat output, thermostat, timer, and flame speed. Because the visual effects can operate independently from the heater, the fireplace can be used for ambiance throughout the year rather than only during colder weather.
The Lumina version adds updated lighting, improved flame presentation, independent ember bed adjustment, a quieter fan, refreshed packaging, smart-device control, and easier access to product support information through the unit’s QR-code system.
Why Choose the Symmetry Lumina Series?
Improved Flame Presentation
Updated LED lighting creates a more refined combination of yellow, orange, and red flame tones. Flame brightness and speed can be adjusted to suit the room and desired atmosphere.
Independent Ember Bed Control
The ember bed can be controlled separately from the flame display. Red, green, and blue channels support a wide range of blended colors and dynamic lighting effects.
Quieter Heater Fan
The Lumina design reduces heater fan noise by approximately 4 dB compared with the prior configuration, supporting a calmer environment during operation.
Updated Smart Controls
WiFi connectivity allows compatible smartphone control of flame brightness, flame color, flame speed, heat settings, temperature, and tray lighting through the supported app.
Front-Flow Heating
Hidden front venting allows the fireplace to be recessed or installed semi-flush while still directing supplemental heat into the room.
Large Viewing Area
The slim frame surrounds a 98 3/8-inch-wide glass viewing area, creating a broad flame presentation suitable for long feature walls and large rooms.

Customizable Flame, Ember Bed, and Mood Lighting

Three Flame Color Channels
Red, yellow, and orange flame channels can be adjusted to create warmer, brighter, or more traditional flame combinations.

Choose low, medium, or high flame speed to change the movement and visual energy of the display.
Independent Ember Bed
The ember bed uses adjustable red, green, and blue channels and can remain on when the main flame display is off.
Mood Lighting
The downlight or mood-light system provides multiple fixed color selections plus a dynamic setting for changing ambient light.
Heat-Free Operation
The flame and lighting effects can be used without activating the heater, making the fireplace suitable for year-round ambiance.
Included Oak Log Set
The standard Oak Log Set adds a familiar fireplace appearance while retaining the clean presentation of a modern linear unit.
Heating Performance and Temperature Control
The built-in heater produces 1500 watts and 4095 BTU of supplemental heat. Amantii rates the unit for spaces up to approximately 400 square feet, although actual results depend on ceiling height, insulation, room layout, exterior temperatures, and other site conditions.
Low, High, and Automatic Heat
The remote provides low heat, high heat, and automatic thermostat modes. Automatic mode cycles the heater in response to the selected temperature.
Adjustable Thermostat
The target room temperature can be set between 59°F and 82°F, equivalent to approximately 15°C to 28°C.
Heating limitation: This fireplace is intended for supplemental room heating. Do not treat its 4095 BTU heater as a replacement for a properly sized primary heating system.
Smart WiFi and Smartphone Control
The SYM-100-LUMINA includes WiFi functionality for connection to the supported TuyaSmart application. Once paired, the app provides control over the fireplace’s main operating functions from a compatible smartphone.
Power and Heat
Turn the fireplace on or off, select heat operation, adjust the target temperature, and view the selected room temperature setting.
Flame and Ember Controls
Adjust flame brightness, flame speed, ember bed lighting, and available mood-light settings through the app interface.
Programmable Timing
Use the app’s supported timing controls to schedule operation according to the available device settings.
WiFi setup requirement: During pairing, keep the mobile device close to the fireplace and enable the phone’s WiFi and location services as directed in the supplied WiFi instructions.
Included Thermostatic Remote
The Lumina Series uses the Amantii R70 remote control, part number 10105070. The remote is designed for the Symmetry Bespoke, Traditional Bespoke, Tru View Bespoke, and Lumina product families.
Heat and Thermostat
Select low heat, high heat, automatic thermostat control, or heater-off operation.
Flame and Lighting
Control flame channels, brightness, speed, ember bed lighting, and available mood-light colors.
Timer Functions
Set a regular countdown timer or program the available 7-day operating schedule after setting the correct day and time.
Remote operation: Point the remote toward the center of the fireplace and confirm that the appliance’s main power switch is in the on position.
Indoor Installation Options
The Symmetry Lumina 100 supports both wall-mounted and built-in installation. Because the unit is more than 100 inches wide, framing, wall construction, electrical placement, and attachment strength must be confirmed before installation.
Built-In Installation
A framed wall opening must be prepared to fit the specified dimensions. The manufacturer directs installers to leave at least 1/4 inch around the appliance and to test the fireplace before completing installation.
Wall-Mounted Installation
The mounting hanger must be secured to a suitable structure, and the supplied safety fastening method must be used to prevent movement. The wall must be capable of supporting the appliance.
Installer guidance: Wall materials and construction methods vary. Consult a qualified builder or installer before mounting or recessing this 100-inch fireplace.
Covered Outdoor Installation Requirements
The SYM-100-LUMINA is suitable for outdoor installation only when it is protected from direct water impingement and installed on the exterior of a primary building or structure. It must not be installed as a freestanding appliance in a standalone outdoor structure.
In addition to the required combustible and mantel clearances, a rain-protection overhang factor of one-half must extend in front of and to each side of the fireplace. The overhang depth must be at least one-half of the measured roof-line height above the base of the fireplace.
Outdoor limitation: Do not install this fireplace where it will receive direct rain, runoff, sprinklers, or other water exposure. Confirm local code requirements before beginning the installation.
Electrical Requirements
- 120V AC, 60Hz electrical supply
- 1500-watt maximum rated power
- 15-amp grounded branch circuit required at the installation location
- A dedicated branch circuit is preferred to reduce nuisance breaker trips or blown fuses
- Do not share the receptacle with other appliances during fireplace use
- Do not use an extension cord
- Do not use a relocatable power tap or power strip
- Use ground-fault protection where required by applicable electrical codes
- All wiring and grounding must comply with local codes
Hardwiring: A qualified electrician must remove the factory cord and connect the appliance directly to household wiring. The live, neutral, and ground conductors must be connected to the marked terminals and the appliance must remain properly grounded.
Safety and Use Requirements
Combustible Materials
Keep furniture, bedding, curtains, paper, clothing, and other combustible materials at least 3 feet from the heater as directed in the manual.
Do Not Block Airflow
Do not cover or obstruct the air intake or exhaust openings. Restricted airflow can cause overheating and may trigger a fault condition.
No Combustible Fuel
Do not burn wood, paper, or any other material inside this electric fireplace.
Damaged Glass or Wiring
Do not operate the fireplace with damaged glass, a damaged power cord, a defective plug, or after the unit has malfunctioned.
Children and Vulnerable Users

Expert Recommendation
The Amantii Symmetry Lumina 100 is best suited to large residential or commercial feature walls where visual scale, smart control, and year-round flame effects matter more than high heating output. Choose this model when you need a wide, modern linear fireplace that can be recessed or wall-mounted and when 4095 BTU of supplemental heat is sufficient for the intended room.
For covered outdoor projects, confirm the overhang dimensions, exposure conditions, wall location, drainage, and electrical code requirements before purchase. Do not select this fireplace for uncovered outdoor areas or standalone structures.
