Installation is straightforward and designed for both DIY enthusiasts and professional installers. Begin by ensuring the area around the flue is clear of any combustible materials – maintain a strict 50mm clearance. Connect the bend to the preceding flue section using the un-barbed female coupler; rotate as necessary to align the chimney system in the desired direction. Secure the connection using the 8-barb twist lock mechanism, and tighten the locking band to ensure a rigid, leak-free joint. Always verify that the coupling is firmly in place and double-check the alignment before proceeding. For further guidance, refer to the manufacturer’s installation manual or contact our technical support team.
