The London Gather Hood 9 x 12 inch - Ø 125 is an essential component for anyone installing a flexible flue liner in their chimney system. Crafted specifically for Mi-Flex 316 and 904 flue liners, this gather hood transitions the fireplace opening to the flexible flue liner, ensuring a seamless connection. General applications include use with wood (under 20% moisture content), smokeless coal, gas, and oil appliances, capable of withstanding temperatures up to 600°C (T600 designation).

The gather hood attaches to the base of the chimney, and appropriate provisions must be made to secure bottom fixings to ensure a gas-tight seal using fire cement, ceramic rope/tape, or high-temperature sealant. Regular maintenance through sweeping by a competent person is crucial for maintaining chimney efficiency and safety, especially for solid fuel appliances, where sweeping is recommended twice annually.

Installation of the London Gather Hood should be carried out with careful attention to detail. Firstly, ensure that your chimney base is properly prepared and stable. The gather hood is fitted at the bottom of the chimney to transition your open fireplace to the flexible flue liner. Use the provided adaptor to attach the gather hood securely to the Mi-Flex liner. To achieve a gas-tight seal, it is essential to use fire cement, ceramic rope/tape, or a high-temperature sealant, following the recommended installation guidelines. Additionally, observe all relevant building regulations, particularly Document J, which highlights the necessity of enclosing the flexible flue liner within a masonry structure. Remember, proper maintenance of the chimney system, including regular sweeping by a competent person, is crucial for both efficiency and safety.

The London Gather Hood is compatible with wood (under 20% moisture content), smokeless coal, gas, and oil appliances.

The gather hood is suitable for applications up to 600°C (T600 designation).

The gather hood transitions the fireplace opening to the flexible flue liner, allowing gasses to flow efficiently up the chimney.

Secure the gather using fire cement, ceramic rope/tape, or high-temperature sealant to ensure a gas-tight seal.

Yes, Building Regulations Document J specifies that flexible flue liners must be installed completely enclosed within a masonry chimney.

It is recommended to sweep the chimney system at least once a year, and for solid fuel appliances, twice annually – at the end of the heating season and before the start of the next.

Chemical cleaners and mild steel tools should not be used to clean stainless steel chimneys.
