## Summary description

Vaillant Kolano 15° (DWZ) flue elbow for concentric 80/125 mm ducts. Designed to connect and redirect flue gas discharge in condensing boilers and venting systems, this DWZ elbow provides a 15-degree offset for routing piping where small angular adjustment is needed. Suitable for use with Vaillant concentric flue systems and compatible 80/125 components.

## Long description

Flue Elbow 80/125 mm, Vaillant Kolano 15° (DWZ) is a concentric duct elbow designed for 80/125 mm flue systems. It provides a 15° angular deviation to enable precise alignment of concentric flue pipes in condensing boiler installations and ventilation routes. The component is intended for use with Vaillant concentric flue systems and compatible 80/125 duct components, allowing compact and reliable routing of combustion gas discharge and fresh air intake within a single concentric assembly.
Advantages
This 15° DWZ flue elbow offers an accurate, low-profile offset that simplifies alignment when straight runs are not feasible. The concentric design keeps the exhaust and intake sealed within the same outer casing, reducing installation space and maintaining correct flow geometry. The part is manufactured to fit standard 80/125 concentric systems, ensuring consistent connection dimensions and stable mechanical fit.
Suitable for
Connecting and redirecting concentric 80/125 flue pipes in domestic condensing boilers
Minor angular adjustments where a 15° offset improves routing around obstacles
Retrofit or replacement of existing concentric flue system elbows with matching diameters
Key specifications
Concentric duct configuration for combined exhaust and intake
Nominal diameters: 80 mm (inner) and 125 mm (outer)
Angular deviation: 15 degrees
Material: corrosion-resistant metal or compatible flue-grade material suitable for condensing boiler flue gases
Connection type: push-fit or compatible sealed joint for concentric components
How to use
Install the elbow as part of the concentric 80/125 flue run, orienting the 15° bend to achieve the required alignment between boiler connection and the subsequent ducting. Ensure mating surfaces are clean and free of debris, then join the elbow to adjacent concentric sections using the system-specific coupling method. Verify correct seating and seal integrity according to the boiler manufacturer’s installation instructions and local ventilation codes. After installation, inspect joints and supports to confirm secure mechanical fixation and correct drainage for condensate if applicable.
Usage recommendations
Use this elbow only within compatible concentric 80/125 systems and follow the appliance manufacturer’s guidance. Check that the angular offset provides sufficient clearance for maintenance and does not impede condensate flow or create low points where moisture can accumulate.
