Installation Guidelines
Proper installation is crucial not only for the optimal performance of your flue system but also for ensuring safety. Before you begin the installation:
1. Plan Your Layout: Ensure all flue components are positioned correctly in line with manufacturer guidelines.
2. Maintain Clearance: Always keep at least a 50mm gap from any combustible materials. This is a critical safety standard that must never be overlooked.
3. Use Appropriate Gaskets: For all joints in P1 and H1 systems, ensure that high-quality jointing gaskets are used to secure leak-proof connections.
4. Secure the Joints: Employ the push-fit jointing mechanism and fix each connection with the Locking Band. This helps guard against potential displacement or leaks.
Overcoming Common Objections

With proper installation, you can expect years of optimal performance backed by a 10-year warranty.
Compatibility with Existing Systems: This product is specifically tailored for non-condensing applications within cascade header systems. If your system meets these criteria, you can integrate the tee fitting without any compatibility issues. For those using condensing systems, however, please consider alternative components that better meet the system requirements.
