How to measure (60 seconds)
- Pick your size: 43" (compact) vs 55" (statement focal point).
- Framing cutout (W×H×D): measure your framed opening and match the “Framing / cutout” values in the fit table.
- Depth available: confirm at least 11 1/2" framed depth (minimum) for the clean-face cavity.
- Front clearance: plan for 36" clearance to combustibles from the front.
- Power plan: minimum 15A, 120V/60Hz circuit required (dedicated preferred).
Clearance note
Quick reference (per manufacturer): Sides 0", Floor 0", Top 0", Back 0", Front 36". Keep furniture, drapes, bedding materials, and all combustibles at least 3 feet from the front.

Installation notes (3-sided clean-face)
The Scion Trinity is designed as a built-in, three-sided clean-face fireplace. Use the notes below to avoid common planning mistakes.
Built-in: frame to the cutout, keep the front clearance
Build your framed opening to the “Framing / cutout” dimensions in the table. Maintain 36" minimum clearance to combustibles from the front. Sides/floor/top/back are zero-clearance.
Why choose the Scion Trinity series
- Panoramic 3-sided viewing: a dramatic, architectural flame presentation visible from multiple angles.
- Truly flush finish: clean-face design allows finishing materials to meet the edge for a built-in look.
- Highly customizable aesthetics: multiple flame colors and ember-bed color options (model dependent) for a tailored look.
- Realistic media options: premium log set plus crystal/ember media for a high-end presentation.
- Flexible ambiance: enjoy flames with or without heat for year-round use (heat is supplemental).
Electrical: minimum 15A, 120V/60Hz circuit required. Follow local code and use a qualified electrician if needed.
Size-by-size guidance (recommendations)
The fit table above is the source of truth for framing dimensions. The notes below are shopping guidance to help you choose faster.
43" model
SF-SCT43-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 footprint makes it easy to integrate into standard wall sections while still delivering a premium, built-in three-sided flame presentation.
Viewing area: 42 1/2" W × 14 3/4" H
Framing / cutout: 42 3/4" W × 22 5/8" H × 11 1/2" D (min.)
Firebox / shell: 42 1/2" W × 22 1/4" H × 11 1/4" D
55" model
SF-SCT55-BK
Best for: Living rooms and media walls paired with medium-sized TVs.
