The Top Plate - Ø 125 is a critical component designed to provide strong support for MI-FLEX 316 and 904 flexible flue liners. Measuring 400mm square, this plate works in sync with a Top Clamp and Top Insert Sleeve, ensuring that the flue liner’s weight is effectively managed at the top of your chimney stack. Manufactured to comply with Building Regulations Document J, this top fixing accessory is suitable for a range of fuel types including wood (with moisture content <20%), smokeless coal, gas, and oil.
Rated for appliance use up to 600°C (T600 designation), our top plate guarantees a secure installation when adhered to correct guidelines. Proper chimney preparation is crucial – ensure that your chimney stack is fully weatherproofed, structurally sound, and that all pots are in good condition. For maintenance, an accessible design allows for easy inspection and cleaning, ideally performed twice a year by a certified professional, such as those registered with HETAS.
Cleaning should never involve chemical agents or mild steel tools to avoid damage to stainless steel parts. This top plate is not just a purchase; it’s a long-term investment in the safety and efficiency of your chimney system.
