The Gather Hood (300X200) - Ø 150 from our MI-FLEX range is meticulously designed to facilitate the efficient flow of gases from your open fireplace through the flexible flue liner. It is crafted to integrate seamlessly with MI-FLEX 316 and 904 flexible flue liners, making it a crucial part of a complete chimney system. Building Regulations Document J mandates that flexible flue liners must be fully enclosed within a masonry chimney.
This gather hood meets those standards and is suitable for use with wood (with less than 20% moisture), smokeless coal, gas, and oil appliances, supporting temperatures up to 600°C (T600 designation). Installation is straightforward: the gather hood attaches itself at the base and top of the chimney chamber, securing into the brickwork with metal flaps. For optimal performance and to ensure a gas-tight seal, use fire cement, ceramic rope, tape, or high-temperature sealant at the connection points.
Regular maintenance and sweeping, performed by competent personnel, are crucial for the longevity and safety of your chimney system. We suggest bi-annual sweeps for solid fuel appliances to keep your system clear of deposits and blockages.
