ENERGETIC RECOMMENDATION:
Sealed – cold decoupled
Counteracts condensation and energy loss
Stops cooling down the fireplace1
Double flap for high tightness
Energetic necessity in every new building
New houses are built more and more tightly. This causes that fireplaces has to use combustion air from the outside. In this case it is clever to install the combustion air
system lockable.² You can avoid that the fireplace cools down if it is not running. Using conventional flaps can counteract only limited cooling down the fireplace.

The CB double flap system solves this problems.
The patented CB double flap system (sealed/cold decoupled) is developed especially for this area of application. It is designed to avoid condensation formation and
that cold air cannot even reach the living space.
Problem 1:
Conventional isolation flaps – especially at free standing stoves –
generally are inside of the house. The part until the flap cools down – in this case
into the living space.
Problem 2:
Conventional isolation flaps only have one flap. This flap can also cool
down.
Problem 3:
Conventional isolation flaps are built in a metal tube. The metal tube
loses warmth and cold enters the room – also if the flap is closed.
Cold fireplaces in warm living spaces cause many problems:
Condensation or water drop development on the combustion air tube
Condensation or water drop development on underneath or on the back of
the fireplace
This could cause oxidation on the combustion air tube and on the fireplace and
also damages on the bottom.
1Stops cooling down the fireplace if the flap is closed. 2Relating to the installation of the double flap it is absolutely necessary to obey the specification of fire protection and building law of the federal state or country.For any requests please ask your responsible agency. If the double flap is used as combustion air tube it is absolutely necessary to follow the building law and fire protection law of the
federal state or country. You receive the information on your responsible agency or your chimney sweeper could give you advice regarding the combustion air tube.
