ICS - The double-walled stainless steel chimney system

ICS flue system

ICS

ICS is a Twin wall insulated chimney system for gas, oil, wood and multi-fuel. Available in 80 – 300mm internal diameter.

Highlights

ICS is a twin wall insulated chimney system for use on open and closed stoves, open fires, residential and small commercial multi fuel appliances, with continuous operating temperatures up to 450°C and short firing up to 550°C.

  •  Simple push-fit jointing system, secured by locking band.
  • Advanced corrosion resistant design and construction uses laser welded 316L stainless steel inner liners and 304 stainless steel case.
  • The only stainless steel system to have passed the internationally recognised GASTEC corrosion test.
  • The jointing system increases rigidity and ensures easy draindown of any condensate in the flue.
  • Capillary break prevents moisture being drawn through the joint.
  • Because of the sleeve joint, the insulation in the pipe is able to be continuous along the length of the system ensuring no hot spots.
  • The 25mm high efficiency Superwool™ blanket maintains flue gas temperature, maximising efficiency, improving flue draught on start up and minimising condensation.
  • Low external case temperature.
  • The assembly method allows the inner liner to expand and contract with temperature at the female end. The flue can withstand the temperatures of a soot fire without loosing the integrity of the joints.
  • Generous lead-in edges on liner and case for ease of jointing.

Notes

Manufactured under a Quality Management Scheme approved to BS EN ISO 9001
4 Hour Fire Rating to BS476 Part 20
Certified for corrosion resistance on gas, oil and solid fuel by Gastec, MPA and TÜV
HETAS listed for use on solid fuel applications.

ICS Plus

ICS is converted into ICS Plus by adding a lip seal to each component with a male form on the liner (see ICS Plus diagram below). This creates a twin wall insulated chimney system designed for the new generation of condensing gas and oil appliances, with continuous operating temperatures up to 200°C, short firing up to 250°C, and positive pressure up to 200pa at the appliance outlet.

Fire resistance classification

Schiedel has recently successfully carried out fire resistance tests according to the latest European standard EN 1366-13:2019 “Fire resistance tests for service installations, Part 13: Chimneys” and has reached EI 120 classification for our Double Wall Insulated System Chimney ICS in a closed scenario (type A) for both vertical and horizontal set-ups.

 

Schiedel is the first European chimney manufacturer to have performed the tests according to this latest fire resistance standard for chimneys.
