Twin wall insulated system chimney for gas, oil, wood and multi-fuel. The system is designed so that the outer case is load bearing and the inner liner is free to expand independently, therefore thermal expansion is accommodated within each and every joint of the system.
Features and benefits:
- Available in two versions with a choice of either a bright annealed or a matt black painted stainless steel outer case.
- 100 mm internal diameter pipes.
- Twist-lock bayonet jointing system. Secured by locking band (supplied as standard with all components with a female collar).
- Advanced corrosion resistant design and construction uses laser welded 316 L stainless steel inner liner and stainless steel case.
- The 25 mm of high density mineral wool insulation maintains flue gas temperature, maximising efficiency, improving flue draught on start up and minimising condensation.
- Low external case temperature.
- The inner liner is free to expand through the female collar, allowing for maximum thermal expansion even during a soot fire.
- The inner liner has an engineered design with an inward bead at the female end which acts as a capillary break preventing moisture being drawn through the joint.
- Lip seal packs are available containing a quick fit female lip seal with a grease sachet to allow product to be easily adapted for use in Positive Pressure (P) applications for use on condensing positive pressure appliances.
