Installation Guidelines & Important Considerations
Preparing for Installation
Before beginning the installation process, ensure that all necessary tools and materials are at hand. These include fire cement, ceramic rope, or high-temperature sealant. Inspect the chimney structure to confirm that it is a masonry construction, as the adaptor is specifically designed for such fittings in accordance with Building Regulations Document J.
Step-by-Step Installation
1. Position the Flexible Liner: Start by fitting the MI-FLEX liner within the prescribed masonry chimney setup. Verify that the liner is correctly aligned for optimal functionality.
2. Attach the Adaptor: Secure the Screw-FIX Adaptor to the rigid flue system ensuring it connects seamlessly with the liner. This step is essential to create the transitional joint required for safe operation.
3. Apply Sealant: Use fire cement, ceramic rope, or a high-temperature sealant to fix the bottom of the adaptor firmly. This ensures a gas-tight seal and prevents any potential leakage.
4. Final Inspection: Conduct a thorough inspection to ensure that all fittings are secure and that the adaptor is well-positioned within the chimney system. It is highly recommended that a HETAS registered sweep reviews the installation as part of a regular maintenance schedule.
Warnings and Maintenance
- Do Not Use Chemical Cleaners: Avoid using chemical cleaners or mild steel tools on stainless steel components, as these can compromise the integrity of the surface.
- Regular Checks: Frequent inspections and maintenance by a qualified professional help in preserving the efficiency and safety of the flue system. Sweeping should be performed at least twice a year for solid fuel appliances.
- Compliance is Key: Ensure that the installation complies with all local building regulations and manufacturer guidelines to avoid any issues during inspections or emergency situations.
