## Summary description

Concentric cascade flue system Termet, model for 150/200 main duct diameter with two 80/125 outlets designed to serve two boilers without built-in automation. The unit provides a concentric (coaxial) combustion air and flue gas channeling solution, enabling safe exhaust and air intake routing for dual-boiler installations. Suitable for installations where two separate boiler flues must be combined while maintaining sealed coaxial operation.

## Long description

Concentric cascade 150/200 with 80/125 outlets for two boilers by Termet is a coaxial flue module designed to combine combustion air intake and flue gas evacuation for dual-boiler installations. The unit accepts a main concentric duct of 150/200 mm and provides two separate 80/125 mm outlets to connect two boilers without integrated automation. The design preserves sealed coaxial operation to ensure safe routing of intake air and exhaust gases while consolidating multiple connections into a single external penetration.
Advantages
The concentric cascade minimizes the number of roof or wall penetrations by enabling two boilers to share a combined coaxial system while keeping each appliance’s airflow paths separated. Its coaxial configuration supports balanced intake and exhaust flows and helps maintain sealed combustion, reducing the risk of spillage or backflow. The component is intended for compatibility with standard concentric ducts and offers a compact solution for installations where space or penetrations are limited.
Suitable for
 Residential or light-commercial installations with two wall- or roof-mounted boilers
 Situations requiring a single external penetration for two appliances while preserving concentric operation
 Projects where each boiler lacks built-in cascade automation and requires independent flue connection
Key specifications
 Main concentric duct diameter: 150/200 mm (outer/inner configuration for the cascade module)
 Boiler outlet connections: two concentric outlets sized 80/125 mm each
 Configuration: coaxial (concentric) channels for air intake and flue gas evacuation
 Application: connects two boilers into a combined sealed flue system without integrated automation
 Installation orientation: suitable for wall or roof penetration where concentric ducts are used
How to use
Install the concentric cascade module at the planned penetration point following local building codes and flue installation rules. Connect the main 150/200 mm concentric duct on the external side and attach each boiler’s 80/125 mm concentric connection to the corresponding outlet. Ensure all joints are sealed and supported according to manufacturer and regulatory requirements. Commission each boiler individually to confirm proper combustion air supply and exhaust flow through the combined system.
Usage recommendations
Verify compatibility between this concentric cascade and the specific boiler models in use, checking clearances, draft requirements and recommended termination components. Use qualified installers for sealed flue assemblies and perform pressure and leak checks after assembly. Regular inspection and maintenance of the flue paths are recommended to preserve safe operation.
