Simplifire Scion Linear Electric Fireplace Size Guide: 43"-78"

Compare 43", 55", and 78" Scion models to confirm framed opening (cutout), finish opening (finishing stops), depth, and 120V electrical requirements before you buy.

How to measure (60 seconds)

  • Pick your size: 43" (compact), 55" (mid-size), or 78" (statement wall).
  • Framed opening (cutout): confirm your framing meets the “Framed opening / cutout” values in the fit table.
  • Depth: confirm at least 7 5/8" depth for the recessed cavity.
  • Finish opening: finish material to the appliance finishing stops (height is consistent across sizes; widths vary by model).
  • Power plan: plan for a 15A, 120V/60Hz circuit. These units are hardwire only (dedicated preferred).

Installation type selector

Pick your finishing method to see the right constraints and notes.
Overlap fit: best for drywall (and thinner finishes)
Recommended when the wall is finished with 1/2" drywall (or facing material not exceeding 9/16" thickness beyond the wall framing). Finish material to the appliance finishing stops, then install the Front/Trim Ring so it overlaps the edges of the finish.
Electrical + clearance quick reference
Hardwire for 120V. Minimum 15A, 120V/60Hz circuit required (dedicated preferred). Clearances: Sides/Floor/Top/Back 0"; Front 36"; Mantel 0" (depth unlimited).
Inside fit: clean-face look without the trim ring
Finish the wall material to the appliance finishing stops, then install the Front without the Trim Ring for a sleeker, built-in appearance. Use the same cutout depth/height requirements from the table.
Electrical + clearance quick reference
Hardwire for 120V. Minimum 15A, 120V/60Hz circuit required (dedicated preferred). Clearances: Sides/Floor/Top/Back 0"; Front 36"; Mantel 0" (depth unlimited).

Size-by-size guidance (recommendations)

The fit table above is the source of truth for opening sizes. The notes below are shopping guidance to help you choose faster.

43" model

SF-SC43-BK
Best for: Smaller feature walls, bedrooms, or home offices.
Why: It offers a modern linear aesthetic for spaces where a massive 60"+ unit would be too large. Its compact 44 1/2" actual width makes it easy to integrate into standard wall sections while still providing a generous 41 1/2" viewing area.
Viewing area: 41 1/2" W × 15" H
Cutout (min.): 45" W × 24 1/4" H × 7 5/8" D
Finish (stops): 43 5/8" W × 17 1/8" H

55" model

SF-SC55-BK
Best for: Living rooms and media walls paired with medium-sized TVs.
Why: This mid-sized model is often the “sweet spot” for standard living areas. It provides a substantial flame presence (53 1/4" viewing width) that balances well with common television sizes and large furniture.
Viewing area: 53 1/4" W × 15" H
Cutout (min.): 57" W × 24 1/4" H × 7 5/8" D
Finish (stops): 55 3/8" W × 17 1/8" H

78" model

SF-SC78-BK
Best for: Grand rooms, large basement build-outs, and commercial spaces.
Why: With an 80" actual width and a nearly 77" viewing area, this model creates a dramatic architectural statement. It is ideal for filling long, expansive walls where a smaller unit would look undersized.
Viewing area: 76 7/8" W × 15" H
Cutout (min.): 80 1/2" W × 24 1/4" H × 7 5/8" D
Finish (stops): 79" W × 17 1/8" H
