Overview:
Part of the comprehensive MF20 MI-FLEX accessories range, these components are meticulously crafted for compatibility with MI-FLEX 316 and 904 flexible flue liners, creating a seamless chimney system when installed together.
General Application:
Engineered to work in conjunction with MI-FLEX Multi-fuel flexible flue liners, in adherence with Building Regulations Document J. Flexible flue liners must be entirely enclosed within a masonry chimney, not compatible with non-masonry enclosures like timber or plasterboard boxing. Suitable for appliances operating at temperatures up to 600 degrees (T600 designation) and adaptable for Wood
Terminals:
Terminals play a crucial role in preventing water ingress or the intrusion of Vermin/Birds into the flue. Additionally, these components support the vertical weight of the flue liner in the structure of the chimney pot. The chimney structure’s integrity is paramount, ensuring chimney pots are crack-free, and appropriate flaunching is done at the stack’s top.
Specific Application:
The Rain Cap is exclusively designed to provide top-tier rain protection for the chimney stack, ensuring optimal performance when paired with the top plate and clamp. Its design obviates the need for an insert, streamlining the installation process.
Maintenance:
A well-maintained chimney system is essential, allowing for hassle-free sweeping and maintenance. Sweepings should be conducted by qualified individuals. For solid fuel applications, consult the list of HETAS registered sweeps at www.hetas.co.uk. Avoid using chemical cleaners or mild steel tools for sweeping stainless steel chimneys. Regular cleaning and inspection, preferably at least once a year, are recommended. Chimneys serving solid fuel appliances should ideally undergo biannual sweeps to remove deposits and check for blockages or bird nests.
