The Joiner Ø 125 is an essential component in the MI-FLEX 316 and 904 multi fuel flexible flue liner systems. Crafted to seamlessly join two pieces of multi fuel liner, it is a critical part of any flexible flue installation. Building Regulations Document J emphasizes that flexible flue liners must be enclosed inside a masonry chimney, and our Joiner Ø 125 ensures compliance with this requirement.Designed for use with wood <20% moisture, smokeless coal, gas, and oil appliances, the Joiner Ø 125 can handle temperatures of up to 600°C (T600 designation), making it a versatile choice for various fuel types.
The accessory is particularly useful for extending the chimney liner when lengths exceed the maximum flex available. It's important to note that while it is ideal for multi fuel liners, it must not be used on gas liners.For optimal performance, the chimney system should be designed for easy maintenance and sweeping. Regular cleaning is crucial, with annual inspections recommended for all applications and twice-yearly sweeping for solid fuel appliances.
Always use HETAS registered sweeps and avoid chemical cleaners or mild steel tools to maintain the integrity of your stainless steel chimneys.
