Kozy Heat SP34 Gas Fireplace
AUTHORIZED DEALER The Kozy Heat SP34 is the smallest and slimmest direct-vent gas fireplace in Kozy Heat's residential lineup — just 13-1/2 inches deep, 34 inches wide, and 90 lbs, with a modulating burner that adjusts between 14,000 and 20,500 BTU/hr. It's the right choice when other direct-vent fireplaces are simply too large: bedrooms, small dens, vacation cabins, mobile homes, finished attic spaces, and any room where you want a real direct-vent gas fireplace but don't have the depth, width, or heat load that bigger models require.
What Makes the SP34 Different?
The SP34 carries the same engineering choices that make Kozy Heat the brand serious dealers and homeowners trust for cold-climate heating — just packaged in the most compact form factor possible:
- Modulating burner technology — output continuously adjusts between 14,000 and 20,500 BTU/hr (NG) based on room temperature demand, rather than the cycling on/off of single-stage burners. More consistent comfort, lower gas consumption.
- Direct vent operation — sealed two-pipe vent system means the firebox is sealed from the room. No indoor air used for combustion, no combustion exhaust enters the home, and significantly higher efficiency than open or B-vent units.
- Ceramic glass — withstands higher operating temperatures than tempered glass; preserves clarity over years of heat cycling
- Generous viewing area — 28" wide × 20-1/2" tall (574 sq in), surprisingly large given the unit's compact overall dimensions
- Customizable design — front screen available in arched (standard) or rectangular formats; multiple refractory interior options to match different interior styles.

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.
