Installation & compatibility
The FlexiGas DS-32 uses a patent-pending pipe-in-pipe construction, combining an inner corrugated stainless steel gas pipe with a yellow PE cover inside a V0 fire-rated corrugated sleeve. The components are designed in a slidable configuration, allowing the CSST to be inserted and withdrawn. The built-in sleeve is designed to meet the definition of a sleeve under the stated UK regulations and standards, including BS 6891 and IGEM/UP/2, 3 & 7. Always ensure installation is carried out in accordance with applicable regulations and manufacturer requirements.
