Ensure that the Pack 503 installation kit is used strictly in accordance with Building Regulations Document J. The kit is designed for use with a fully enclosed masonry chimney, and it is critical to note that non-masonry enclosures such as timber or plasterboard are not acceptable. Follow a systematic approach: First, verify that your chimney pot is intact and properly prepared. Next, install the flexible flue liner (purchased separately) and then carefully position the Pot Hanging Cowl along with the associated mesh, Nose Cone, Black Pipe Adaptor, and Chimney Notice Plate. Always use the correct sized 125mm flex adaptor and double-check all fittings. If in doubt, consult a competent person or a professional installer to ensure that every component meets safety standards and performs to its full potential.

Pack 503 includes a Stainless Steel Pot Hanging Cowl with Mesh (125mm), a Nose Cone (125mm), an Adaptor to Black Pipe or Single Wall Flue (125mm), and a Chimney Notice Plate.

No, the MI-FLEX flexible flue liner is not included in Pack 503. It must be purchased separately.

Yes, Pack 503 is suitable for use with wood (under 20% moisture), smokeless coal, gas, and oil appliances.

Pack 503 is suitable for use with appliances up to 600°C (T600 designation).

Yes, Building Regulations Document J requires that a flexible flue liner must be completely enclosed inside a masonry chimney. Non-masonry enclosures like timber or plasterboard are not acceptable.

The chimney system should be inspected and cleaned at least once a year. For solid fuel appliances, it’s recommended to sweep the chimney twice a year – at the end of the heating season and before the start of the next.

No, under no circumstances should chemical cleaners or mild steel tools be used to sweep stainless steel chimneys. Only competent persons should perform sweeping.
