When installing Pack 501, ensure that the flexible flue liner is correctly enclosed within a masonry chimney, as non-masonry enclosures (e.g. timber or plasterboard) are not compliant with Building Regulations Document J. Begin by carefully positioning the top plate at the chimney’s crown, using the supplied top clamp to secure it in place. The top insert and nose cone are designed to guide the 125mm flexible flue liner smoothly down the chimney for optimal performance. Use the provided adaptor for a seamless transition to a black pipe or single-wall flue if required. It is recommended that this installation be carried out by a competent person, or under professional supervision, to ensure safety and compliance. Routine chimney maintenance is also vital: arrange a cleaning or sweeping session at least once or twice a year to prevent blockages and maintain peak functionality.
Pack 501 includes a top plate, top clamp, top insert, nose cone, adaptor to black pipe or single wall flue, and a chimney notice plate, all tailored for a 125mm diameter.
Yes, Pack 501 is suitable for appliances using wood (less than 20% moisture), smokeless coal, gas, and oil, and can withstand temperatures up to 600°C.
Yes, Building Regulations Document J requires that flexible flue liners must be completely enclosed within a masonry chimney. Non-masonry enclosures are not permitted.
Your chimney should be cleaned and inspected at least once a year. For solid fuel applications, it's recommended to sweep at the end of the heating season and just before the start of the next season to ensure there are no blockages.
While DIY installation is possible, it's recommended that a competent person or professional installer handles the set-up to ensure compliance with Building Regulations.
The nose cone assists in guiding the flexible flue liner down the chimney, making the installation process easier and more efficient.
Pack 501 is a comprehensive kit, but you may need additional items like a cowl or terminal for weather protection, depending on your specific installation requirements.
