Key Features and Their Benefits
- Dual Stainless Steel Construction: Provides both strength and resistance to corrosion. Your chimney system will remain robust, even under high-temperature conditions.
- High-Temperature Coating: The outer layer’s black coating is designed to withstand extreme temperatures, enhancing the lifespan of your flue system.
- In-built Thermal Insulation: Incorporates compressed rockwool insulation which not only retains heat but also contributes to overall energy efficiency.
- Secure Locking Mechanism: Guarantees that every flue joint is securely connected, reducing the risk of gas leaks or performance inefficiencies.
Understanding the Installation Process
Proper installation is critical. For optimal performance, a locking band must be used at every connection point within your chimney flue system. As you begin the installation, pay close attention to the following:
Step-by-Step Installation
1. Preparation: Clear the area around your chimney flue and ensure you have all the necessary tools. Verify that the locking band fits the diameter of your flue system (Ø 125).
2. Positioning the Locking Band: Place the locking band around the joint that needs to be connected. Ensure that the metal surfaces align perfectly for a seamless fit.
3. Securing the Band: Fasten the locking band tightly at the joint, making sure to maintain an even pressure throughout. This prevents any gaps that might compromise the safety of the installation.
4. Final Inspection: Once installed, inspect the connection to confirm that the locking band is secure and that the flue components are properly aligned. This is important for achieving the certified safety standards.
Installation Considerations
- Safety Zone: Ensure a minimum of 50mm distance is maintained between the external surface of the flue and any combustible material. This is key to reducing fire risks.
- Professional Guidance: If you’re not completely confident in undertaking the installation yourself, it is advisable to enlist the assistance of a qualified heating engineer.
