Description
A Slim Electric Fireplace with Adjustable Multicolor Flames
The Modern Flames Spectrum Slimline is a built-in or wall-mounted electric fireplace featuring multicolor flames and a slim profile designed for installation in 2x4 or 2x6 walls.
Designed for Flexible Wall Installation
The Spectrum Slimline is engineered for projects where wall depth matters. It can be recessed into standard 2" x 4" or 2" x 6" framing or mounted directly to the wall surface. With no combustion and no venting required, installation is simpler than gas or wood alternatives.
This model is intended for indoor use only and does not require chimney or special ventilation, helping maintain indoor air quality.
Customizable Flame Display with Year-Round Use
The flame display features multiple color options with adjustable brightness and speed settings. Flames operate independently from the heater, allowing visual ambiance without heat during warmer months.
Included driftwood logs and clear crystal media enhance the layered appearance of the flame presentation.
Installation Options
The Spectrum Slimline supports fully recessed built-in installation within standard framing or wall-mounted installation using the provided hardware.
It can be plugged into a standard 120V outlet or hardwired for a cleaner look. Always follow manufacturer instructions and local electrical codes.
Controls & Heating Features
Operate the fireplace using the included remote control or the front touchscreen control panel with on-demand lighting.
The unit provides two heat settings (High and Low) and produces approximately 5,000 BTUs, heating areas up to 450 square feet. The built-in thermostat automatically adjusts heat output based on room temperature.
A sleep timer allows automatic shut-off between 30 minutes and 8 hours. The Whisper Quiet fan helps reduce operational noise.
