Modern Flames Orion Slim Electric Fireplaces

Shop the Modern Flames Orion Slim series, linear built-in electric fireplaces in 52, 60, and 100-inch widths. The Slim models use a shallower firebox than the rest of the Orion line, which makes them the option when wall depth is the constraint.

Modern Flames Orion Slim Electric Fireplaces

Orion Slim is the shallow-depth linear option in the Modern Flames Orion line. It delivers the same long horizontal flame format as the rest of the range but in a firebox that fits framing cavities too shallow for a standard built-in fireplace. In practice that is what makes it useful: retrofitting a linear fireplace into an existing interior wall is usually a depth problem, not a width problem, and Slim is the answer to it.

Available in 52, 60, and 100-inch widths, with V2 versions and configurations paired with the Allwood wall system. Because these are single-sided linear fireboxes, framing and finishing are considerably simpler than the multi-sided models, and the shallow depth widens the range of walls that can accept one at all.

Why Buy a Modern Flames Orion Slim Electric Fireplace

  • Shallow firebox depth fits walls that cannot accommodate a standard built-in linear fireplace.
  • Linear format in 52, 60, and 100-inch widths.
  • Simpler framing and finishing than multi-sided models, with only one face to resolve.
  • No venting or gas line required, so interior wall placement is straightforward.

What to Consider When Buying

  • Measure your actual available cavity depth and compare it against the specification. Slim widens the options but still has a minimum requirement.
  • Confirm the rough opening dimensions for your width before framing.
  • Verify the electrical requirement, which may include a dedicated circuit at the larger widths.
  • Compare against the Orion Traditional line if you want conventional firebox proportions rather than a linear format.
  • If your wall depth is generous and the fireplace will be viewed closely, compare against the deeper Orion models for flame presentation.
