Karma stoves with through-the-wall flue gas discharge are room-sealed gas appliances (type C11) with their own combustion air supply and flue gas outlet routed directly through the exterior wall. This means they don't need a chimney – simply drill through the wall and install a suitable flue, which greatly simplifies installation, especially in apartments and houses without a chimney flue.
This group includes the Karma Beta Comfort, Beta Electric and Beta Mechanic series, which differ in their control and ignition method, as well as the older Karma Gamat series (373, 471, 473).
Frequently Asked Questions
- Do I need to worry about a chimney with this type of stove? No, flue gases are discharged directly through the wall, so no chimney is needed.
- What wall thickness can the stove handle? The flue can be extended using extension pieces to suit the thickness of the given wall.
- Which model should I choose? It depends on your preferred control type – Mechanic for simple manual operation independent of electricity, Electric and Comfort for electronic control with greater comfort.
