Pack 501 - (125mm, P/C/PS/N/CNP/MAE) is a comprehensive installation kit tailored to make your chimney installation smooth and compliant. Designed specifically for use with MI-FLEX 316 and 904 flexible flue liners, this pack ensures a fully functional chimney system. Building Regulations Document J underscores the necessity of enclosing flexible flue liners within masonry chimneys — non-masonry enclosures like timber or plasterboard are not acceptable.
Suitable for appliances up to 600°C, this kit is perfect for wood (less than 20% moisture), smokeless coal, gas, and oil. The package includes a top plate, top clamp, top insert, nose cone, adaptor to black pipe or single wall flue, and a chimney notice plate. Routine maintenance and sweeping should be carried out by a competent person at least once or twice a year to ensure optimal performance and safety.
