Attach the provided spacers to the underside of your existing Firestop Plate to guarantee the optimal gap for proper air circulation. Align the TWPro MB Firestop Cover Plate with the pre-fitted magnets and secure it using the integrated Locking Band. Make sure that the cover plate is firmly in place and that the required clearances (50mm for TWPro, 60mm for KC) from any combustibles are maintained. Always follow the detailed installation guide provided with the product and ensure all components are fitted securely before operation. Caution is advised during installation to prevent any potential hazards.
