The Increaser Ø 550 from National Flues stands out as a premium option in the field of flue system accessories, particularly designed to facilitate a smooth transition between flue diameters.
Understanding the Increaser Ø 550
The Increaser Ø 550 is engineered from robust 316L stainless steel, a material known for its excellent resistance to corrosion and high temperatures. This makes the product ideal for use in a variety of applications, including gas and oil systems, boilers, ovens, and even ventilation systems. With its secure push-fit jointing method and integrated locking bands, installation is streamlined and effective. Importantly, the product has been designed to meet strict CE marking requirements and is compliant with EN 1856-1 standards, which ensures that it meets vital safety and performance criteria.
Key Features and Benefits
Durable Construction: The use of high-grade 316L stainless steel not only provides lasting durability but also contributes to the component's resilience against harsh environmental conditions. This robustness significantly reduces the need for frequent replacements, thereby offering long-term cost efficiency.
Seamless Diameter Transition: The core function of the Increaser Ø 550 is to facilitate the transition from a smaller diameter flue to a larger one. This is particularly important when adapting to different heating systems or when upgrading the existing setup. A smooth transition directly impacts the overall performance and efficiency of the flue system.
Secure and Leak-Proof Joints: Our design includes a high-pressure sealing gasket (P1/H1) that is essential for preventing leaks. Whether you are dealing with high-temperature condensing applications or non-condensing environments, the push-fit jointing system secures each connection with precision. This not only improves safety but also enhances the operational efficiency of your heating system.
Certified Safety and Quality: The Increaser Ø 550 boasts a CE mark and adheres to EN 1856-1 standards, ensuring that every component has passed rigorous safety and quality checks. This is crucial for installations in residential, commercial, or industrial settings, where compliance with safety standards cannot be compromised.
Installation Process and Safety Precautions
Installation is Simple: One of the major advantages of the Increaser Ø 550 is its user-friendly installation process. The modular push-fit system allows for quick connections without the need for specialised tools. Each joint is secured with locking bands, ensuring that the system remains stable and leak-proof, even under varying temperature conditions.
Safety First: While the installation process is designed to be straightforward, it is imperative to observe safety precautions. Always ensure that there is a minimum clearance of 50mm between the flue and any combustible materials. This precaution is vital to prevent any potential fire hazards. Additionally, make certain that all joints are correctly sealed with the appropriate gasket. If you are uncertain about any step of the installation, we strongly recommend consulting a certified heating engineer.

Enhancement of your flue system does not have to be limited to the Increaser Ø 550 alone. National Flues offers a range of optional accessories that can further improve the performance and safety of your installation. These accessories include additional sealing solutions, extension parts for custom fitments, and inspection covers that help maintain the overall integrity of your system.
