MI-FLEX Screw-FIX Pot Hanging Cowl, Natural – 125mm: Enhanced Chimney Liner Protection
The MI-FLEX Screw-FIX Pot Hanging Cowl in Natural 125mm is meticulously engineered to meet the new BSEN standard, offering optimal protection for your chimney system. This screw-fix pot hanging cowl features an integrated rain cap and bird guard, providing a shield against external elements. Notably, it facilitates the installation of the chimney liner without necessitating the removal of the pot, ensuring a hassle-free setup process. Designed specifically for MI-FLEX, this cowl is indispensable for supporting the liner’s weight at the chimney pot’s apex.
Overview:
A part of the MI-FLEX-Screw Fix accessories, these screw-on installation fittings are purpose-built for seamless integration with MI-FLEX 316 and 904 flexible flue liners. Their cohesive configuration contributes to a comprehensive system, ensuring reliable chimney functionality.
General Application:
These items are explicitly intended for use alongside MI-FLEX multi-fuel flexible flue liners. Adherence to Building Regulations Document J mandates the complete enclosure of flexible flue liners within masonry chimneys, disallowing non-masonry enclosures such as timber or plasterboard boxing. The products are compatible with appliances operating at temperatures up to 600 degrees (T600 designation) and are suitable for Wood.
Terminals:
Terminals play a crucial role in preventing water ingress or Vermin/Birds into the flue. They are essential when fitting a flue liner onto an appliance lacking a condense drain, effectively stopping excess water from running back to the appliance. Pot hanging cowls like this model support the vertical weight of the flue liner atop the chimney pot, requiring the chimney structure to be structurally sound, with crack-free chimney pots and appropriate flaunching at the stack’s apex.
Specific Application:
Engineered in compliance with the new BSEN standard, the MI-FLEX Screw-FIX Pot Hanging Cowl offers integrated rain protection and a bird guard. Its design enables chimney liner installation without pot removal, serving as a terminal secured to the flex using the standard jubilee fixing method (refer to installation instructions). Please note that this item is exclusively compatible with MI-FLEX systems.
Maintenance:
To ensure an efficiently functioning chimney system, regular sweeping by a competent person is essential. For solid fuel applications, a list of HETAS registered sweeps can be accessed at www.hetas.co.uk. Avoid using chemical cleaners or mild steel tools for sweeping stainless steel chimneys. Regular cleaning and inspection, preferably annually, along with biannual sweeps for chimneys serving solid fuel appliances, help prevent deposits and blockages.
