flue gas discharge into the chimney

Karma stoves with flue gas discharge into the chimney (type B11) are structurally simple gas stoves that, unlike models with through-the-wall discharge, require connection to a functional chimney with proper draft. They draw combustion air directly from the heated room.

This group includes the Gamat B 23, L 30 models and the Gamat S series (S 50, S 70, S 90), which differ mainly in power output and size.

Frequently Asked Questions

• Is a chimney required for these stoves? Yes, flue gases are discharged into a chimney with sufficient draft – without one, the stove cannot be operated.
• What's the difference compared to through-the-wall stoves? This type draws combustion air directly from the room and discharges flue gases through the chimney, while through-the-wall models have a sealed combustion chamber with both air supply and discharge through the exterior wall.
• Which model should I choose? It depends on the power output and size of the heated space – the S series (50/70/90) offers a wider range of power outputs than the B 23 and L 30.
