The Large Gather Hood (300x400) - Ø 180 from our MI-FLEX accessories range is designed to be an essential component in the installation of MI-FLEX 316 and 904 flexible flue liners. Creating a secure and efficient connection between the flue liner and open fireplace, this gather hood ensures optimal gas flow, directing it safely up the chimney. Compliant with Building Regulations Document J, this gather hood is suitable for use with appliances reaching temperatures up to 600°C, including those burning wood with less than 20% moisture, smokeless coal, gas, and oil.
For best results, pair it with bottom fixings to create a gas-tight seal with fire cement, ceramic rope, or high-temperature sealant. Ensure your chimney system allows for easy sweeping and maintenance, with cleaning recommended twice a year for solid fuel appliances.
