The Element4 Sky Small Tunnel is a compact see through gas fireplace designed to frame a clean, modern flame view between two adjoining spaces. Its linear tunnel format offers a direct line of sight through the fire, creating a visual connection between rooms while delivering an efficient and realistic flame display. Powered by the Real Flame Burner and detailed cleaved wood logs, it produces a convincing wood fire effect with an 89% efficiency rating and adaptable heat outputs for natural gas (G20/G25) and propane (G31), making it well suited for smaller and medium sized interiors.
With its minimal installation depth, the Sky Small Tunnel fits neatly into narrow wall cavities, providing designers with flexibility when planning open plan layouts or room transitions. Optional Powerfan technology supports long or difficult flue routes, while anti reflective glass keeps the flame view crisp and unobstructed on both sides. Optional black reflective panels add visual depth inside the firebox, and multiple control solutions—remote control, the Puck controller, Wi-Fi app control, or full home automation integration—allow users to manage the fireplace in whatever way suits their space. Additional accessories such as LED bottom lighting, a wall switch, Invisimesh safety screen, an access door, and various convection grille styles offer both functional and aesthetic customisation.
Constructed from durable black steel as standard, the Sky Small Tunnel is built for long term stability and a streamlined architectural appearance. Its through view design allows the fireplace to act as a subtle divider or a dramatic feature between rooms, while maintaining an attractive flame image even at low settings. Combining efficient heating, precision engineering, flexible installation, and a distinctive double sided format, the Sky Small Tunnel stands out as an elegant compact tunnel fireplace for contemporary homes and commercial interiors.
