Short description
VISIO TUNNEL separates and connects rooms while providing a two-sided view of the fire. Designed as an architectural element, it combines a large visible flame with comparatively low heat output thanks to advanced firebox technology, making it suitable for well-insulated spaces with modest heating needs.

Key features

• Two-sided fire view (tunnel) — fire visible from two rooms.
• Smooth-running lift door for easy, quiet loading of logs.
• Infrared-coated ceramic glass panes to control radiant heat and support efficient combustion.
• Efficient window rinsing (air-wash) to keep glass largely soot-free.
• Dark-stained oak handle and black steel frame as selectable design elements.
• Available handle options (steel or wood) and various finish choices for integration in architectural projects.

Additional advantages / product highlights

• ADVANCED GLASS CONCEPT©: cleaner glass, reduced wood consumption and improved energy efficiency.
• Controlled radiant-heat emission via infrared-coated glass for comfort with large viewing areas.
• Design firebox lining options for a refined visual appearance of the combustion chamber.
• Practical ash drawer for simple removal of cold ash.
• AIR system option for room-air independent operation and more convenient control.

VISIO TUNNEL is suited for use as a partition or architectural connecting element between spaces where a two-sided fire view is desired. Recommended fuel: well-seasoned hardwoods such as beech, birch or oak, with target moisture content around 17–20 % (measure with a wood moisture meter).
