The Full Picture
How a 100 Inch Linear Electric Fireplace Fits a Standard Wall
Start with the wall. The finished opening is 98-7/8" wide by 16-1/4" high and 4" minimum deep, and it is non load bearing.
Wall mounting uses the supplied bracket, set into studs where possible and into the supplied drywall anchors where not. You can also install it beneath a TV, and it comes with do it yourself installation instructions.

Who It's For
The Modern Flames Spectrum Slimline electric fireplace suits a homeowner with a long great room, bedroom or basement wall and a standard 2x4 frame. So does a business with a long interior wall. It also fits anyone who wants a clean linear look and has no room for deeper framing.
How the Hybrid-FX LED Flame Works
The Hybrid-FX LED flame is made from light, not video. High intensity LED lighting with layered optics creates the effect.
- Atmospheric look: The flame looks more atmospheric than realistic.
- Ember bed: Glacier crystals make the bed, and the log set has 16 driftwood logs.
- Color memory: The unit remembers the last flame and ember bed color you used.
