Product information

Description

Vaillant Exhaust Extension Pipe DN80/125, 1 m (model 303203) is an extension element for flue and ventilation systems with nominal diameters DN80 and DN125. The 1-metre straight section is intended to lengthen exhaust runs, adapt routing and connect compatible modular chimney components in residential boiler and water heater installations. The product is designed for use with systems that accept DN80/125 fittings and provides a standardized connection for safe evacuation of combustion gases when installed according to manufacturer guidance.

Advantages

The extension pipe provides a single-piece, uniform cross-section to maintain proper gas flow in DN80/125 systems. Its 1 m length offers flexibility when adapting flue layouts without requiring custom cutting or on-site fabrication. The component is compatible with modular chimney and ventilation parts that share the same nominal diameters, enabling straightforward assembly and secure mechanical connections. Materials and dimensions conform to the expectations for residential heating exhaust components, ensuring predictable fit and function when integrated into appropriate systems.

Suitable for

Extending exhaust runs on residential boilers and water heaters with DN80/125 connections
Adapting flue routing to avoid obstacles or match installation geometry
Connecting modular chimney components in venting systems with matching nominal diameters
Replacement of a worn or missing straight section within an existing DN80/125 flue assembly

Key specifications

Nominal diameters: DN80 and DN125 compatible connection
Length: 1 metre (straight section)
Function: exhaust extension for ventilation and flue systems
Intended application: residential boiler and water heater installations

How to use

Install the extension pipe as part of the flue system by aligning the DN80/125 ends with compatible adjoining components and engaging the designed mechanical connections or seals. Ensure that joints are secured according to system requirements and local codes, maintaining correct slope and clearance for safe condensate and gas discharge where applicable. Verify that the assembled length, routing and support comply with the heating appliance manufacturer's installation instructions before commissioning the system.

Usage recommendations

Use the extension only with compatible DN80/125 components and follow all installation instructions and local regulations. Inspect joints after installation for airtightness and secure support to prevent sagging or stress on connections. When in doubt, consult a qualified heating technician or refer to the appliance manufacturer's guidance.
