Kalfire GP110/79T Gas Fireplace — Tunnel Gas Fire with Wide Double-Sided Flame View
The Kalfire GP110/79T Gas Fireplace delivers a bold tunnel fire experience with glass on both sides. Designed by Kalfire, it creates a continuous flame view that connects two spaces while still maintaining architectural definition.
Because of its wide tunnel layout, this model works especially well as a stylish divider in open-plan interiors. In addition, it combines strong visual impact with efficient combustion performance.
Kalfire GP110/79T Gas Fireplace tunnel glass design
The Kalfire GP110/79T Gas Fireplace uses glass on both sides, so the flames remain visible from two connected areas. As a result, the fire creates visual flow between spaces while still defining separate zones.
Moreover, this layout enhances openness and light distribution. Therefore, it is often used in modern architectural and luxury residential projects.
Tunnel gas fireplace with Hybrid LED and NSG options
Kalfire offers optional Hybrid LED technology, so the fireplace can produce a soft glowing ember bed beneath the flames. In addition, this feature enhances ambience even during lower flame operation.
Furthermore, the optional Natural Spark Generator adds realistic spark movement above the fire. Because of this, the flame effect becomes more dynamic and visually engaging. Overall, the experience feels more natural and immersive.
Interior options for Kalfire GP110/79T Gas Fireplace
The interior remains a key visual element, even when the fireplace is not lit. For this reason, Kalfire provides multiple finish options.
You can choose a flat interior for a minimal look, while a design interior adds depth and texture. In addition, black ceramic glass creates a darker and more dramatic fire appearance. Consequently, the fireplace adapts easily to different interior styles.
Mounting trims for flexible installation depth
Mounting trims allow flexible adjustment of installation depth, so the fireplace fits neatly into different wall constructions. For this model, options include 3 cm, 7 cm, and 10 cm depths with 4 mm or 8 mm thicknesses.
Moreover, this flexibility ensures a precise built-in finish. Therefore, installers can achieve a tailored architectural integration.
