The Medium Gather Hood (300x300) - Ø 180 is an essential component for any fireplace setup requiring a flexible flue liner. Specifically designed for MI-FLEX 316 and 904 flue liners, this gather hood enhances the efficiency of your chimney system by creating a larger area for gas flow. Building Regulations Document J mandates that a flexible flue liner must be enclosed within a masonry chimney, and our gather hood fits seamlessly within these regulations.

Suitable for use with wood (less than 20% moisture), smokeless coal, gas, and oil, it can handle temperatures up to 600°C (T600 designation). The gather hood includes an adaptor for easy connection to the flue liner and comes with metal flaps for secure attachment to the chimney brickwork. Maintenance is straightforward, requiring yearly inspections and bi-annual sweeping for solid fuel appliances.

For peace of mind, ensure a competent professional conducts these tasks.

Ensure the flexible flue liner is correctly installed within a properly constructed masonry chimney as stipulated by Building Regulations Document J. Attach the Gather Hood firmly using the provided adaptor and metal flaps to secure it to the chimney brickwork. For a gas-tight seal, use fire cement, ceramic rope, high-temperature tape, or sealant as required. It is essential to inspect your chimney annually and conduct bi-annual sweeping for solid fuel appliances. Always consult a qualified professional to perform installation and maintenance, ensuring both safety and regulatory compliance.

Yes, the Medium Gather Hood is specially designed for use with MI-FLEX 316 and 904 flexible flue liners.

This gather hood is suitable for use with wood (less than 20% moisture), smokeless coal, gas, and oil, and can withstand temperatures up to 600°C.

The gather hood comes with metal flaps that can be folded at right angles and screwed into the brickwork at the top of the chimney chamber.

No, Building Regulations Document J requires flexible flue liners to be completely enclosed within a masonry chimney. Non-masonry enclosures like timber or plasterboard boxing are not acceptable.

Ensure that the connection to the flexible flue liner is made within the confines of the existing masonry chimney. The use of fire cement, ceramic rope, high-temperature tape, or sealant is advisable to create a gas-tight seal.
