The Top Plate Ø 300 is an essential component for anyone installing MI-FLEX 316L and 904 flexible flue liners. Designed to provide robust support at the top of your chimney stack, this top plate works in conjunction with a Top Clamp and Top Insert Sleeve to safely bear the vertical (dead) weight of your flue liner. As per Building Regulations Document J, it is imperative that flue liners are installed entirely within a masonry chimney for safety and efficiency.
Suitable for use at up to 600°C (T600), the plate can be deployed on appliances burning wood (with less than 20% moisture), smokeless coal, gas, and oil. Ensuring a weatherproofed chimney stack and sound chimney construction are prerequisites for its installation.
