Why this product?
3-Year extended warranty

Adjustable Direct air supply

Direct air supply with horizontal / vertical adjustable nozzle on the back of the device

Clean glass

The clean glass system slows deposit buildup on the glass. An air supply above the glass creates a protective curtain. The preheated air is propelled along the glass. It triggers combustion of gas and volatile materials, thereby protecting the glass against smoke and soot deposits.

Diffusion of warm air by forced ventilation - new turbines

The device is equipped with 2 powerful and silent tangential fans.
2 speeds – boost via switch

Intermittent and 3 hour extended burning

The unit can alternate between intermittent and extended burning mode. Intermittent mode requires frequent addition of new wood. It is particularly high-performing and respectful of the environment. Extended burning mode, with a low flame, enables 3 hours of operation without intervention.
