The Gather Hood (400x300) - Ø 250 is an integral component in the installation of flexible flue liners, particularly above open fireplaces. Part of the robust MI-FLEX 316 and 904 flexible flue liner system, this gather hood ensures the effective escape and upward flow of gases through a chimney liner. The gather hood, crafted from high-quality materials suitable for use with wood (moisture <20%), smokeless coal, gas, and oil, can withstand temperatures up to 600°C (T600 designation). Building Regulations Document J mandates the use of a fully enclosed masonry chimney for installation. The gather hood comes with an adaptor that connects to the flexible flue liner, ensuring a secure fit. The base attachment to the chimney is facilitated by folding the metal flaps at right angles and securing them into the brickwork. For optimal performance, secure your connections with fire cement, ceramic rope, or a high-temperature sealant. Easy maintenance and sweeping provisions are built into the chimney system design. Remember, solid fuel chimneys should ideally be swept twice a year by a competent HETAS-registered sweep to prevent blockages and buildup.

Installation Instructions: Ensure the gather hood is positioned at the base of the chimney liner. Fold the integrated metal flaps at right angles and secure them into the brickwork using appropriate fixings. It is essential to apply fire cement, ceramic rope, or a high-temperature sealant around the connections to form a gas-tight seal. Always adhere to Building Regulations Document J, which requires the complete enclosure of flexible flue liners within a masonry chimney. For maintenance, schedule sweeping at least twice annually by a HETAS-registered professional to avoid soot and creosote buildup.

The Gather Hood (400x300) - Ø 250 is used in conjunction with flexible flue liners to facilitate the escape and upward flow of gases from open fireplaces through the chimney liner.

The gather hood is suitable for use with wood (moisture <20%), smokeless coal, gas, and oil appliances.

The gather hood can withstand temperatures up to 600°C (T600 designation).

The gather hood should be securely attached at the base of the chimney, with the metal flaps folded at right angles and screwed into the brickwork. Use fire cement, ceramic rope, or high-temperature sealant for a gas-tight seal.

The chimney system should be designed for easy sweeping and maintenance. It is recommended to sweep chimneys serving solid fuel appliances at least twice a year by a HETAS-registered sweep.

No, chemical cleaners or mild steel tools should not be used to sweep stainless steel chimneys. Instead, use appropriate tools and methods for cleaning.

Building Regulations Document J requires flexible flue liners to be installed completely enclosed inside a masonry chimney. Non-masonry enclosures like timber or plasterboard boxing are not acceptable due to safety and efficacy concerns.
