The MI-FLEX Pot Hanging Cowl in Terracotta - Ø 150 is an exceptional accessory designed for use with MI-FLEX 316 and 904 flexible flue liners. As part of the MF20 MI-FLEX accessory family, it ensures the complete integrity of your chimney system when installed correctly. Engineered for use with multi-fuel flexible flue liners, it complies with Building Regulations Document J, requiring installation within a masonry chimney.

This product is suitable for high-temperature applications, withstanding up to 600°C (T600 designation), and can be used with wood (<20% moisture), smokeless coal, gas, and oil appliances. Designed to prevent water, vermin, or birds from entering the flue, it is crucial when your appliance lacks a condense drain. The pot hanging cowl not only supports the flue liner's vertical weight but also ensures the chimney structure is sound and the chimney pots are intact.

Complying with the latest BSEN standards, it features an integrated rain cap and bird guard. Easy to install with the standard jubilee fixing method, it offers enhanced rain protection and bird prevention without removing the chimney pot. For maintenance, ensure easy access for sweeping and inspection, which should occur at least once yearly.

For solid fuel appliances, bi-annual sweeping is recommended by HETAS registered sweeps to keep the system clear of deposits and blockages.

To install the MI-FLEX Pot Hanging Cowl, first confirm that your chimney pot is in sound condition and that you are working within a masonry chimney as required by Building Regulations Document J. The standard jubilee fixing method is recommended to secure the accessory without removing the chimney pot. Carefully align the flue liner and ensure that it is correctly positioned before affixing the cowl. Once installed, regular maintenance such as annual inspections and bi-annual sweeping for solid fuel appliances is advised. If there is any uncertainty during installation, consulting a professional installer is strongly recommended to ensure compliance with all safety regulations.

The MI-FLEX Pot Hanging Cowl is suitable for wood (with less than 20% moisture content), smokeless coal, gas, and oil appliances, able to withstand temperatures up to 600°C.

It prevents water, birds, and vermin from entering the flue, while also supporting the flue liner's weight and providing increased rain protection through its integrated rain cap.

Yes, according to Building Regulations Document J, the flexible flue liner and its accessories must be installed within a masonry chimney.

While it is technically possible to install the pot hanging cowl yourself using the standard jubilee fixing method, it is recommended to seek professional installation to ensure compliance with safety regulations and optimal performance.

Regular maintenance includes an annual inspection and sweeping. For solid fuel appliances, bi-annual sweeping by HETAS registered sweeps is recommended to remove deposits and check for blockages.

Ensure that the chimney structure and pots are in good condition without cracks before installing the pot hanging cowl. Proper flaunching at the top of the stack is essential.

You can find HETAS registered sweeps on the official HETAS website at www.hetas.co.uk for professional chimney sweeping services.
