Before installation, ensure that the transition from MI-Flex to TWPro occurs within an existing Class 1 chimney stack. Secure the mounting plate atop a lowered chimney stack using the provided Locking Band that firmly fastens all components. Always maintain the required 50mm clearance from any combustible materials such as wood, plasterboard, or similar. It is recommended to consult a professional installer if unsure about any steps, as a proper and secure installation is vital for both performance and safety. Double-check that all welds and fittings are intact and that the plate is level before finalising the installation.

The Chest Mounting Plate Ø 150 is compatible with solid fuel and gas/oil appliances including woodstoves, gas coal effect fires, and boilers.

The plate features an outer skin made from 304 grade stainless steel and an inner skin from 316 grade stainless steel, both 0.4mm thick, with high-density rockwool insulation.
