## Summary description

Flue extension pipe for Vaillant systems, model 303255. Straight DN80 (80 mm nominal diameter) aluminium/steel flue extension with 2 m length for extending exhaust/ventilation ducts. Designed to connect and lengthen existing flue runs, suitable for boiler and ventilation installations that require an additional 2 m section of DN80 pipe.

## Long description

Flue Extension Pipe Vaillant DN80 2 m 303255 is a straight DN80 aluminium/steel flue section with a 2 metre length designed to extend exhaust and ventilation ducts in Vaillant boiler and ventilation systems. The component provides a seamless addition to existing DN80 flue runs where extra length is required to reach roof outlets, wall terminals or connection points while maintaining appropriate flow and structural alignment.
Advantages
The extension pipe combines aluminium and steel construction for a balance of corrosion resistance and mechanical strength, ensuring durability in standard boiler exhaust conditions. Its straight DN80 profile preserves inner flow characteristics, minimising turbulence and backpressure when joined correctly to compatible flue components. The 2 metre length reduces the number of joints required compared with shorter sections, simplifying installation and lowering potential leak points.
Suitable for
Extending DN80 flue systems in domestic and light-commercial Vaillant boiler installations
Reaching roof outlets, wall terminals or remote connection points that require an additional 2 m of flue run
Replacement of damaged or corroded straight DN80 sections in ventilation ducts compatible with aluminium/steel materials
Key specifications
Nominal diameter: DN80 (80 mm)
Length: 2.0 m
Construction: aluminium/steel composite
Profile: straight, cylindrical section for inline extension
Compatibility: designed for use with Vaillant DN80 flue components and other DN80 systems meeting the same connection geometry
How to use
Verify that the existing flue run is DN80 and that connection ends match the extension pipe geometry. Before installation, inspect the pipe for any shipping damage and ensure mating ends and seals are clean and undamaged. Slide or couple the extension into the existing flue section using the applicable clamps, couplings or seals recommended by the boiler manufacturer. Maintain correct alignment and secure fastenings to prevent movement; ensure all connections follow applicable local codes and the Vaillant installation guidelines for clearances and support intervals. After installation, perform a system smoke or pressure test where required and check for leaks or abnormal drafts.
Usage recommendations
Use this DN80 2 m straight extension only within the parameters specified by the boiler and flue manufacturer. When extending flue runs, consider support spacing, thermal expansion, and condensate drainage as applicable. If unsure about compatibility or local regulatory requirements, consult a certified heating engineer or the Vaillant installation manual to confirm correct selection and safe installation.
