The Screw-FIX Pot Hanging Cowl, Natural - Ø 175, is an expertly designed accessory that perfectly complements MI-FLEX 316 and 904 flexible flue liners, creating a full chimney system when installed together. This cowl is essential for anyone looking to maintain the structural integrity and functionality of their flue system, whether for wood (<20% moisture), smokeless coal, gas, or oil appliances, up to temperatures of 600°C (T600 designation). Building Regulations Document J mandates the use of a flexible flue liner only within a fully enclosed masonry chimney, rendering non-masonry enclosures like timber or plasterboard boxing unacceptable. The terminal's primary role is to prevent water and vermin or birds from entering the flue, which is especially crucial for appliances lacking a condensate drain. Additionally, it distributes the vertical weight of the flue liner on the chimney pot while ensuring the pot’s structural soundness and appropriate flaunching. The Screw-FIX Pot Hanging Cowl also incorporates a rain cap and bird guard, providing extra protection and ease of installation without removing the chimney pot.
