With a certified clearance of 50mm from combustibles, this component meets the highest standards of safety and durability.
Key Features & Benefits
Superior Material Quality: The dual-layer design utilises premium stainless steel grades, offering excellent resistance to corrosion and wear. This means fewer maintenance hassles and a longer lifespan for your flue system.
Safety and Compliance: With HETAS approval and CE marking, the product guarantees that it complies with rigorous European safety standards. The 50mm clearance to combustibles is a crucial feature, minimising the risk of overheating and potential hazards.

Installation Guidelines
Pre-Installation Checks
Before you begin, ensure that the flue system and appliance are cool and that you have read the manufacturer’s installation instructions. It is essential to maintain a safe environment during installation, so plan ahead and prepare the necessary tools and safety gear.
Step-by-Step Process
- Step 1: Confirm that all components such as the locking band and mounting materials are available.
- Step 2: Clean the connection areas on both the single wall and the twin wall sections to guarantee a secure and tight fit.
- Step 3: Attach the increaser using the provided locking band, ensuring that it fits snugly into place. Check that the 50mm clearance from combustible materials is maintained.
- Step 4: Once installed, conduct a thorough safety check to ensure that there are no loose components or potential hazards.
Post-Installation Advice
After installation, monitor the system during the first few uses. It is advisable to re-inspect the connection and locking band after initial operation periods to ensure optimal performance.
The Importance of Optional Accessories
While the Single Wall to Twin Wall Increaser is designed to function efficiently as a standalone component, there are several optional accessories available that can further enhance your flue system. Accessories such as additional insulation sleeves, vapor barriers, and customised locking mechanisms can complement the primary function of the increaser. By choosing these add-ons, you not only boost the performance and robustness of your setup but also extend the lifespan of your entire installation. We encourage you to explore these options on our website to fully tailor your system to your needs.
Addressing Common Concerns
Safety and Compliance
One of the most significant concerns when choosing a flue component is safety. With the Single Wall to Twin Wall Increaser, you can be confident that every aspect of safety has been considered. The 50mm clearance is pivotal in preventing excessive heat transfer to adjacent combustible materials. Moreover, its HETAS and CE certifications stand as a testament to its compliance with international standards.

Another frequent question is about durability. Our increaser’s dual-layer construction utilises high-quality stainless steel, guaranteeing resistance against harsh weather conditions and corrosive environments.
