The Gather Hood (400x300) - Ø 300 is a vital component in the installation of MI-FLEX 316 and 904 flexible flue liners. Designed to fit seamlessly in chimney systems, this gather hood aids in the efficient escape of flue gases from an open fireplace, directing them up the chimney liner. Building Regulations Document J mandates that flexible flue liners be fully enclosed inside a masonry chimney, ensuring safety and compliance.

Ideal for appliances operating up to 600°C (T600 designation), it's perfect for wood with less than 20% moisture, smokeless coal, gas, and oil. Secure connections are crucial; use fire cement, ceramic rope, tape, or high-temperature sealant for a gas-tight seal. Ensure your chimney system is designed for easy cleaning and maintenance by a competent person.

Regular maintenance, including sweeping by HETAS registered professionals, is recommended, especially for solid fuel appliances, to prevent blockages and deposits.

For optimal performance, install the Gather Hood by securely fixing it to both the base and the top of the chimney chamber. Begin by ensuring proper measurements and a clean working area. Use appropriate high-temperature sealants like fire cement, ceramic rope, or specialised tape to achieve a gas-tight seal. Double-check that the flexible flue liner is completely enclosed within the masonry chimney, and refrain from leaving any visible sections of the liner. Regularly inspect for any signs of wear or damage and adhere to maintenance routines as specified by building regulations. Always engage a HETAS registered professional for chimney sweeping and maintenance.

Yes, the gather hood complies with Building Regulations Document J, requiring that flexible flue liners be fully enclosed inside a masonry chimney.

The gather hood is suitable for wood with less than 20% moisture, smokeless coal, gas, and oil appliances, supporting temperatures up to 600°C (T600 designation).
