Description
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 is the smallest direct-vent gas fireplace Kozy Heat makes. At 34 inches wide, 30-7/8 inches tall, 13-1/2 inches deep, and only 90 lbs, it fits installation spaces no other Kozy Heat model — and most other direct-vent fireplaces from any manufacturer — can match. Standard direct-vent units need 19-22 inches of depth. The SP34 needs 14 inches of framing depth. That difference opens installation possibilities that other fireplaces simply won’t accommodate.
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.
