The Top Plate Ø 200, measuring 400mm square, is an essential accessory for ensuring the integrity and functionality of your chimney system. Designed to be used with MI-FLEX 316 and 904 flexible flue liners, this top plate supports the weight of the liner at the top of the stack. It is built for strength and durability, handling temperatures up to 600°C (T600 designation).

The installation must comply with Building Regulations Document J, which specifies that a flexible flue liner must be enclosed entirely within a masonry chimney. This top plate, in conjunction with a Top Clamp and Top Insert Sleeve, provides a complete and secure solution for flue installation. Ideal for use with wood (<20% moisture), smokeless coal, gas, and oil appliances, this top plate is tailored to high-performance standards.

Regular maintenance, including chimney sweeping by a HETAS-registered professional, is recommended to ensure optimal performance and longevity.

For a safe and compliant installation, ensure that the Top Plate Ø 200 is fitted at the top of your masonry chimney where the MI-FLEX flexible flue liner terminates. It is essential to secure the top plate using the appropriate top clamp and insert sleeve. Installation must comply with Building Regulations Document J, which dictates that the flue liner and its supporting accessories be entirely enclosed within a masonry structure. Although some experienced DIY enthusiasts may attempt installation, we strongly recommend that a HETAS-registered professional carry out the process to guarantee proper installation and safety.

The top plate measures 400mm square, making it an ideal fit for MI-FLEX chimney systems.

This top plate is designed for use with MI-FLEX 316 and 904 flexible flue liners, suitable for wood (<20% moisture), smokeless coal, gas, and oil appliances.

The top plate can handle temperatures up to 600°C, ensuring it can cope with high-performance flue systems.

While DIY installation is possible, we strongly recommend having the chimney system installed by a competent person to ensure it complies with Building Regulations Document J.

Regular maintenance and chimney sweeping by a HETAS-registered professional are essential. Cleaning should be conducted at least twice a year for solid fuel appliances.

No, Building Regulations Document J requires that the flue liner and associated components must be fully enclosed within a masonry chimney.
