The MI-FLEX Pot Hanging Cowl (Natural) - Ø 150 is a premium installation accessory designed for seamless use with MI-FLEX 316 and 904 flexible flue liners. Perfect for creating a full chimney system, this cowl ensures your flue is secure and protected. Compliance with Building Regulations Document J means it can only be installed within a masonry chimney, not in timber or plasterboard enclosures.

Suitable for appliances up to 600ºC (T600 designation), it handles wood with <20% moisture, smokeless coal, gas, and oil. The pot hanging cowl attaches to the chimney pot and takes the vertical weight of the liner while blocking rain and bird ingress. Ensure regular sweeping and maintenance by competent personnel, especially for solid fuel applications.

Follow installation instructions carefully for optimal performance.

• Verify that the chimney pot is in pristine condition without cracks and ensure it has been correctly flaunch-ed at the top of the stack. • Install only within a masonry chimney in compliance with Building Regulations Document J; avoid timber or plasterboard enclosures. • Follow the manufacturer's installation instructions meticulously to guarantee both safety and performance. • Regular chimney sweeping by a competent person is essential, especially for solid fuel systems, which should be inspected and cleaned twice during the heating season.

This cowl is designed for use with MI-FLEX 316 and 904 flexible flue liners. It's suitable for combustion of wood with under 20% moisture, smokeless coal, gas, and oil.

No, per Building Regulations Document J, it must be completely enclosed within a masonry chimney. Timber or plasterboard enclosures are not acceptable.

The cowl is suitable for use with appliances operating up to 600ºC (T600 designation).

It features an integrated rain cap and bird guard which prevent rain and birds from entering the chimney, safeguarding your flue system.

Regular sweeping by a competent person is vital. Solid fuel chimneys should be swept at least twice a year, once at the end and once at the start of the heating season. Avoid using chemical cleaners or mild steel tools on stainless steel chimneys.

Ensure that the chimney pot is in good condition without any cracks and that appropriate flaunching is done at the top of the stack.

The terminal is secured to the flex using the standard jubilee fixing method.
