- Description
- Extra Details
The Screw-FIX Increaser, 1mm thick and sized at Ø 175-200mm, is an essential component for flue system installations. This 316 stainless steel adapter acts as a transitional joint, seamlessly connecting single wall rigid flue systems to the highly flexible MI-FLEX 316 and 904 flue liners. Designed for versatility, it is suitable for solid fuels like wood (moisture content <20%), smokeless coal, gas, and oil, handling temperatures up to 600°C (T600 designation).Building Regulations Document J mandates its installation within masonry chimneys, prohibiting non-masonry enclosures such as timber or plasterboard boxing. The bottom fixings ensure a gas-tight seal using fire cement, ceramic rope, tape, or high-temperature sealant, preventing the flexible liner from being exposed.Easy provision for maintenance is a key feature, requiring routine cleaning and sweeping by a certified professional, preferably a HETAS registered sweep.
Solid fuel systems should be swept at least twice annually to ensure safety and efficiency, removing any blockages or deposits like bird nests.
