Air-gas flue pipe DN80/125, white, push-in 500mm 2651466

Flue gas exhaust system for condensing boilers

This white concentric air/flue gas pipe with dimensions DN80/125 is a key element for the proper operation of condensing boilers. It is designed with a push-fit system, which significantly simplifies installation and reduces the installer's working time. Thanks to the use of plastic, the pipe is resistant to chemical corrosion, which often occurs as a result of flue gas condensation. The white color allows for an aesthetic match with the facade or interior of the building, without the need for additional painting.

The 500 mm length makes this element ideal as a connecting segment or for filling short sections in ventilation and flue gas exhaust systems. The concentric construction (pipe within a pipe) allows for simultaneous air intake for combustion and flue gas exhaust through a single channel. This solution not only saves space in the wall but also eliminates the risk of flue gases backing up into the room.

Key features and applications:

• Push-fit system: Installation is performed by inserting one element into another, ensuring tightness without the need for additional seals or adhesives at each connection.
• Chemical-resistant material: Plastic guarantees long service life even in the environment of acidic condensates formed during the operation of a condensing boiler.
• Universal dimensions: The DN80/125 cross-section is a standard for many popular wall-mounted and floor-standing boiler models with a capacity up to 30-40 kW (depending on the manufacturer).
• Aesthetics and durability: The white color is durable and does not fade under UV radiation, which is important for outdoor installation.

It is worth remembering that when designing the installation, appropriate slopes for horizontal pipes must be maintained so that condensate can flow freely back to the boiler or condensate trap. This specific model, as a plastic system component, is lightweight and easy to process – it can be easily cut to the required length using standard carpentry or plastic cutting tools. This allows installers to quickly adapt the pipe layout to the building's specifics without the need to order custom lengths from the manufacturer.
