PH Cowl – 125mm: Optimal Protection and Functionality for Your Chimney
This PH Cowl in 125mm size, designed to meet the latest BSEN standard, offers exceptional functionality and protection for your chimney. With an integrated rain cap and bird guard, this standard-fit pot hanging cowl not only facilitates chimney liner installation without pot removal but also prevents bird entry and enhances rain protection. Positioned at the top of the chimney pot, it effectively supports the liner’s weight while being secured to the flex using the standard jubilee fixing method (refer to installation instructions).
Overview:
MF20 MI-FLEX accessories comprise a range of installation fittings tailored for use with MI-FLEX 316 and 904 flexible flue liners, ensuring a comprehensive and efficient chimney system when used together.
General Application:
These items are intended for use in conjunction with MI-FLEX Multi-fuel flexible flue liners. According to Building Regulations Document J, flexible flue liners must be fully enclosed within a masonry chimney. They are suitable for appliances operating up to 600 degrees (T600 designation), accommodating Wood.
Terminals:
Terminals play a crucial role in preventing water, Vermin, and Birds from entering the flue. Pot hanging cowls support the vertical weight of the flue liner within the chimney pot structure, which must be soundly constructed. Chimney pots should be free from cracks, and appropriate flaunching at the stack’s top is necessary.
Specific Application:
This standard-fit PH Cowl in 125mm size adheres to the latest BSEN standard, featuring integrated rain protection and bird guard functionality. It not only facilitates chimney liner installation but also ensures bird prevention and superior rain protection.
Maintenance:
For optimum performance, the chimney system should allow easy provision for sweeping and maintenance. Sweeping must be conducted by competent personnel. Avoid using chemical cleaners or mild steel tools on stainless steel chimneys. Regular cleaning and inspection, at least annually, are recommended to prevent deposits or blockages, especially in chimneys serving solid fuel appliances.
