DOUBLE FLAP
No danger of cooling down the combustion air tube
or the fireplace.
Cold fireplace elements in warm living spaces
cause big problems.
Condensate formation or water drops on the
combustion air tube is the consequence.
The CB double flap system stops condensation
and water drop development.
Patented innovation
Advantages:
High storage efficiency due to automatically closing of the flaps after combustion process
No operating error possible
Counteracts condensation and energy loss effectively
Double flap opens automatically at power breakdown
Low wood consumption
Building-authority approved on the DIBt (German institute for building technology)
Function:
If the fireplace is not running it is energetic necessary to lock the external combustion air supply. The double flap adapts to the fireplace. If the fireplace is running, the
double flap is open and supply of combustion air is ensured. After the combustion process the double flap closes and avoids cooling down the fireplace.
