Installation is straightforward and designed for ease and safety. Begin by ensuring the installation surface is clean and stable. 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.

The TWPro MB Firestop Cover Plate is suitable for use with solid fuel and gas/oil appliances, including woodstoves, gas coal effect fires, and oil and gas boilers.

This product is HETAS-approved and CE-marked, conforming to safety standards including EN1856-1 T600 N1 W V2 L50040 G50 and T200 W V2 L50040 O20, for both TWPro and KC models.

The plate has an outer skin made from 304 grade stainless steel and an inner skin from 316 grade stainless steel, both 0.4mm thick, with compressed rockwool insulation (200kg/m3 TWPro / 128Kg/m3).

The required distance to combustibles is 50mm for TWPro and 60mm for KC models.

The parts are secured together using a Locking Band, and the cover plate is attached to the existing firestop plate with magnets and spacers to ensure proper air circulation.

The Locking Band ensures a secure and stable connection between the parts of the TWPro Twin Wall Insulated Chimney, facilitating safe and efficient installation.

Proper air circulation prevents overheating and ensures the appliance operates safely and efficiently, without compromising the integrity of the firestop system.
