Key Features and Benefits
Adjustability:
- The telescopic design enables you to adjust the pipe length anywhere from 350mm to 530mm, providing the perfect fit for varying installation requirements. This flexibility ensures that your chimney system can accommodate unique spatial constraints without compromising on performance.
Superior Construction:
- Crafted with a 304 stainless steel outer layer and a 316 stainless steel inner layer, both with a thickness of 0.4mm, the Sflue Adjustable Pipe promises durability and exceptional resistance to corrosive environments. This is essential for maintaining long-term reliability and performance.
High-Quality Insulation:
- The inclusion of compressed rockwool insulation, with a density of 230kg/m³, ensures that thermal efficiency is maximised. This not only aids in energy retention but also acts as a safeguard, particularly important where appliances generate high levels of heat.
Safety Approvals:
- The product is HETAS approved and CE marked, complying with the stringent standards under the EN1856-1 T450 N1 D V2 L50040 G50 designation. This gives you the confidence that every aspect of the product is aligned with both safety and performance standards.

Addressing Common Objections
Many customers initially have concerns about the complexity of installing a new chimney system component. However, the Sflue Adjustable Pipe has been designed with user comfort in mind. The twist-lock mechanism is intuitive, reducing the need for specialised tools and services. If you are unsure about adjusting the pipe length or aligning the insulating material properly, the straightforward design minimises potential errors, making it an excellent choice for DIY installations.
Another common concern is the longevity of the product. With a construction featuring two grades of high-quality stainless steel and rockwool insulation, the flue pipe offers a robust lifespan and a 15-year warranty. This means that your investment in safety and efficiency will yield benefits for many years to come. The HETAS and CE marks further underscore the reliability of the product, demonstrating that it meets rigorous international standards.
Technical Insights
Understanding the technical specifications of your flue system is crucial in ensuring it meets your specific needs. The precise dimensions and materials of the Sflue Adjustable Pipe have been selected to provide optimal thermal performance and structural integrity. The 127mm diameter is ideal for a wide range of applications, and the dual stainless steel construction guarantees resistance to environmental factors such as moisture, heat, and corrosion. With the flexibility to extend the flue pipe length as needed, you can achieve the perfect configuration for your chimney, regardless of spatial limitations. The insulation technology not only enhances safety but also improves energy efficiency by minimising heat loss.
Installation Guidelines
Proper installation is critical for both the performance and safety of your flue system. Begin by ensuring that there is a minimum 50mm clearance from any combustible materials. Follow the manufacturer’s instructions carefully and utilise the provided Locking Band to secure the twist-lock couplers firmly in place. During installation, double-check the alignment and sealing between each component to ensure there are no gaps that could compromise the thermal insulation or safety clearances. If in doubt, seeking professional installation services can further guarantee that all parameters are correctly met.
Maintenance and Longevity
Once installed, maintenance for the Sflue Adjustable Pipe is minimal due to its durable stainless steel construction. Periodic visual inspections are recommended to ensure that the locking mechanisms remain secure and that the pipe continues to show no signs of wear or insulation degradation. Addressing minor issues promptly can extend the lifespan of your flue system, thus ensuring consistent performance over time.
