The Kozy Heat Alpha 36S is unique in the Kozy Heat catalog — a clean-face, frameless traditional gas fireplace that eliminates the conventional metal frame around the firebox glass for an unobstructed view of the flame. The result is the most realistic open wood-burning fireplace look available in a sealed-combustion gas appliance. Available with a standard arched front or optional rectangular front, the Alpha 36S offers a 35-3/16 inch wide by 29-7/8 inch tall viewing area (approximately 1,051 sq in of visible flame), modulating 24,000 to 48,000 BTU/hr output, dual 75 CFM blowers standard, and a built-in accent light kit — making it one of the most fully-equipped premium gas fireplaces in Kozy Heat's lineup.

The Clean-Face Design: What Makes the Alpha 36S Different?

Most premium gas fireplaces have a visible metal frame surrounding the glass — the Alpha 36S doesn't. By removing the conventional framed face, the Alpha 36S provides an uninterrupted view of the firebox interior and flame from the surrounding wall surface. The visual effect is meaningfully closer to an open wood-burning fireplace than a typical gas appliance — closer to "fire in a hole in the wall" than "gas fireplace with a frame around the glass." For homeowners who want the gas convenience and efficiency of a modern direct vent fireplace but the visual character of a traditional masonry wood-burning fireplace, the Alpha 36S is the closest available match in the Kozy Heat catalog.

The clean-face design provides two practical benefits beyond aesthetics:

Enhanced radiant heat — without the metal frame absorbing and conducting heat away from the firebox opening, more radiant heat travels directly out into the room. The unobstructed firebox surface acts more like an open hearth than a constrained gas firebox.
Improved visual presence in stone, tile, or masonry surrounds — the clean-face design integrates more seamlessly into substantial surround treatments (full-wall stone, custom tile work, masonry hearths) because the fireplace doesn't compete with the surround for visual weight. Designers and builders working on premium custom projects often specify clean-face fireplaces specifically for this integration capability.

Standard Features (Premium Equipment Bundle)

The Alpha 36S includes a comprehensive standard equipment bundle that's unusual for a wall-mounted gas fireplace at this size:

Dual 75 CFM blowers (standard) — two 75 CFM circulation fans included as standard equipment. Most Kozy Heat fireplaces have a single fan kit (when fans are included at all); the Alpha 36S's dual-blower configuration moves substantially more warm air into the room.
Accent Light Kit (standard) — built-in LED accent lighting that illuminates the firebox interior, particularly effective when paired with the clean-face design's unobstructed view
Komfort Kontrol Remote — Full Function — precision temperature, flame height, and on/off control
Modulating burner (24,000–48,000 BTU NG) — continuously adjusts output rather than cycling on/off, holding steady comfortable temperatures
IPI Electronic Ignition — modern intermittent pilot ignition with full electronic control
High-Low Regulator — built-in modulating gas regulator
High-Quality Lifetime Glass — ceramic glass with manufacturer's lifetime spec
Engineer-Designed Burner System — Kozy Heat's proprietary burner geometry
Screen Front (standard) — safety screen included in either arched or rectangular configuration
Direct Vent — sealed combustion, no chimney required
ANSI Z21.88 Certified — vented gas heater certification
