Its adjustable design, which can be set between 30 and 45°, makes it ideal for a variety of installation scenarios, ensuring a secure and aesthetically pleasing finish.
Key Features and Their Benefits
- High-Quality Materials: The stainless steel construction guarantees longevity while resisting corrosion and damage, making it a wise long-term investment.
- Enhanced Safety: The integration of compressed rockwool insulation not only improves thermal performance but also addresses safety concerns by maintaining a safe distance of 50mm from combustibles.

Installation Process and Important Considerations
Before beginning the installation, it is imperative to make sure that all preliminary safety checks are completed. Follow these steps for optimal installation:
1. Preparation: Clean the flue thoroughly and ensure the wall surface is free from dust, grease, or debris. Verify that all components and tools, especially the silicone and screws, are at hand.
2. Positioning: Accurately position the finishing plate around the flue. Ensure that it is correctly aligned with the non-combustible wall, and adjust to the required angle (between 30 and 45°).
3. Fixing: Apply the recommended silicone to the contact areas and firmly fix the plate using screws. Remember, maintaining a 50mm clearance from combustibles is non-negotiable for safety.
4. Securing: Use the integrated Locking Band to lock the finishing plate securely in place. This additional safety measure reinforces the connection between the chimney flue and the finishing plate.
Following the detailed guidelines will help ensure that your installation is not only secure and effective but also compliant with all relevant safety standards.
