The London Gather 9 x 9 inch - Ø 150 is expertly crafted for use with Mi-Flex 316 and 904 flexible flue liners. Designed to perfection, this gather hood facilitates a seamless transition from your chimney's fireplace opening to the flexible flue liner, ensuring optimal gas flow and safety compliance. Ideal for multi-fuel applications, it adheres to Building Regulations Document J, which mandates that flexible flue liners must be installed within masonry chimneys.

The London Gather is constructed to withstand high temperatures up to 600°C (T600 designation) and is suitable for use with wood (moisture content <20%), smokeless coal, gas, and oil appliances. This robust accessory includes secure attachment provisions and requires high-temperature sealant, fire cement, or ceramic rope for a gas-tight seal. Regular maintenance and sweeping, preferably by certified HETAS professionals, are crucial to ensure the chimney system remains clean and safe.

Regular inspections, particularly for solid fuel systems, will help prevent blockages like bird nests and build-ups.
