Air-exhaust flue pipe DN80/125, white, push-fit 1000mm 2651467

Exhaust Gas Removal and Air Intake System

This white, double-walled duct, 1000 mm in length, is a key component of modern ventilation systems for gas appliances. Designed as a coaxial pipe, it combines the functions of supplying fresh air for combustion and removing exhaust gases to the outside of the building. Thanks to the push-fit system, installation is quick and requires no additional gaskets or adhesives – the elements simply slide into each other, significantly reducing the installer's working time. The white casing color allows for aesthetic integration with facades or interiors, eliminating the need for painting or additional pipe covering.

Application and Technical Compatibility

The duct is dedicated to devices with DN80 connection diameter (inner pipe) and DN125 (outer pipe), making it a universal solution for many condensing and wall-mounted boilers. The double-walled construction provides thermal insulation of exhaust gases within the inner pipe, preventing excessive heating of the outer wall and protecting the surroundings from high temperatures. At the same time, the air layer between the pipes acts as an insulator, minimizing heat loss in the air supply duct.

In practice, this means dividing the functions into two independent channels:

• The inner channel with a diameter of 80 mm is responsible for transporting hot exhaust gases from the boiler directly to the outside.
• The outer annular space with a diameter of 125 mm is used for drawing in cold atmospheric air necessary for the combustion process.

Such a configuration guarantees system tightness and operational safety, eliminating the risk of exhaust gas backflow into rooms.

Installation and Practical Benefits

The push-fit system (so-called "push-fit") is a solution appreciated by installers for its simplicity and reliability. There are no complicated threaded or welded connections here – it is sufficient to push the elements until they stop, and the elastic gaskets (usually built into the ends) ensure the hermeticity of the connection.

Key practical aspects:

• Fast installation: No need to use specialized tools when connecting sections.
• Safety: Thermal insulation protects against burns when touching the outer wall of the pipe.
• Durability: The casing material is resistant to corrosion and weather conditions, which is crucial for external installation.
• Versatility: Suitable for standard boilers requiring a closed system (so-called "pipe-in-pipe").

It is worth remembering that when planning the installation route, minimum distances from window and door openings must be taken into account in accordance with current building regulations for the specific type of gas appliance. The 1-meter length allows for flexible adaptation of the system to various external wall or roof configurations.
