Callaway See Thru Gas Fireplace
AUTHORIZED DEALER The Kozy Heat Callaway See-Thru is a 50-inch see-through (double-sided) direct-vent gas fireplace — engineered to install in a wall between two rooms, with ceramic glass on both sides so the fire is visible from either space simultaneously. With a 53-1/2" × 16-3/4" linear viewing area, modulating 18,500–35,500 BTU/hr burner, and surprisingly slim 17" depth despite the dual-sided design, the Callaway See-Thru is an architectural feature first and a heater second — designed for custom homes, major renovations, and design-led installations where a fireplace serves as both visual focal point and physical connection between two living spaces.
What Makes the Callaway See-Thru Different
See-through fireplaces are a specialty product category, and the Callaway is one of the more refined options in the residential market. Beyond the dual-sided viewing, the Callaway carries the design choices that make Kozy Heat the brand serious designers, builders, and homeowners trust:
- Modulating burner technology — output continuously adjusts between 18,500 and 35,500 BTU/hr based on room demand, rather than the cycling on/off of single-stage burners. More consistent comfort, lower gas consumption.
- Surprisingly slim 17" depth — most one-sided fireplaces of this width need 19-22 inches of framing depth. The Callaway See-Thru fits in standard 2x6 wall framing (with appropriate clearances), which makes interior wall installations much easier than competitors that require thicker walls.
- Linear horizontal viewing area — 53-1/2" wide × 16-3/4" tall produces a wide, modern flame display that reads as architectural detail rather than traditional appliance
- Ceramic glass on both sides — withstands the higher operating temperatures of an exposed-on-both-sides firebox
- Direct vent operation — sealed combustion with exhaust outside; no indoor air loss, no combustion byproducts in either room
- Extensive heat distribution options — Komfort Zone Kit, Interior and Exterior Heat Transfer Kits, Power Vent System, and Vented Cavity (TV-above-fireplace compatibility)

Kozy Heat Gas Fireplace FAQs
What makes Kozy Heat gas fireplaces different from wood fireplaces?
Gas fireplaces offer easier operation, less mess, and more consistent control than a traditional wood-burning fireplace. There is no wood hauling, ash cleanup, or manual fire starting.
What is a direct vent gas fireplace?
A direct vent fireplace draws combustion air from outside and vents exhaust outdoors. This makes it a popular choice for modern installations.
Can I install a Kozy Heat gas fireplace in a room without a chimney?
Often, yes. Many direct vent gas fireplaces can be installed without a masonry chimney, but installation depends on vent routing, clearances, local code, and the selected model.
Are Kozy Heat gas fireplaces for heat or decoration?
Both. Many homeowners choose them for supplemental heat, while others use them as a design centerpiece with realistic flames and decorative media.
Can I choose between traditional and modern styles?
Yes. Kozy Heat offers traditional log-style fireplaces as well as modern linear and contemporary designs.
Should I choose a gas fireplace or gas insert?
Choose a gas insert if you already have an existing wood-burning fireplace you want to convert. Choose a gas fireplace if you are building a new fireplace location or replacing a full fireplace system.
