For optimal performance, ensure that the Pack 506 Installation Kit is installed within a masonry chimney according to Building Regulations Document J. This kit is designed exclusively for use with MI-FLEX flexible flue liners, which must be purchased separately. Always consult a competent professional to verify that your installation meets all safety standards. The components should be assembled in the order specified in the user manual, ensuring that the adaptor correctly blends the flue dimensions. Additionally, remember that regular maintenance such as annual chimney sweeps is crucial to both safety and efficiency. Avoid installing in non-masonry enclosures to remain compliant with regulations.

Pack 506 includes a Stainless Steel Pot Hanging Cowl with Mesh (125mm), a Nose Cone (125mm), an Increasing Adaptor (100mm SW to 125mm Flex), and a Chimney Notice Plate.

No, the MI-FLEX liner is not included in this installation kit. It must be purchased separately.

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

Pack 506 components are rated for appliances up to 600°C (T600 designation).

No, Building Regulations Document J requires that a flexible flue liner be installed only within a masonry chimney.

Chimneys should be swept at least once a year, with solid fuel appliance chimneys recommended to be swept twice a year—once at the end of the heating season and again at the start.

Sweeping should be carried out by a competent person. For solid fuel applications, you can find a list of HETAS registered sweeps at www.hetas.co.uk.
