Our 100mm Direct Ventilation Kit is designed to deliver a consistent external air supply to wood burning and multi-fuel stoves with 100mm diameter air inlets. By drawing combustion air from outside, it enhances stove performance, improves efficiency, and helps maintain a comfortable indoor environment—particularly in modern, airtight properties.
This system connects directly to the stove’s air intake, preventing the appliance from using warm air within the room. As a result, it reduces heat loss while also eliminating unwanted draughts or light entering the living space.
The semi rigid aluminium duct is constructed from a non combustible material to DIN 4102 Class A1 standards and is suitable for temperatures up to 250°C, ensuring reliable and safe operation. The external 6×6 louvre grille is UV stabilised to resist sun exposure, helping maintain durability and appearance over time.
Supplied as a complete kit, it includes all necessary components for straightforward installation.
