A multi-functional twin wall insulated venting system, which is suitable for internal and external use on a wide range of engineering, combustion and process equipment, including heating appliances, diesel generators, combined heat and power (CHP) systems and service ducting.

The product is supplied to a high quality specification as standard, including a 1.4404 (316L) grade stainless steel liner, high performance mineral blanket insulation and a bright annealed 1.4301 (304) grade stainless steel outer case.

Both liner and outer case have a continuous seam welded joint and each flue gas bearing component has a uniquely profiled spigot and socket joint with bevelled end forms to ensure ease of installation whilst ensuring the joint meets H1 performance criteria at 5000 Pa.

The thermal insulation blanket ensures continuous insulation over the entire effective length of the liner, ensuring fast priming to normal operating temperatures, whilst maintaining low external surface temperatures.

Chimneys are subject to significant corrosion attack by flue gas condensates, particularly from solid fuel and condensing appliances. ICS is specifically designed and manufactured to resist this corrosion. It is the only stainless steel chimney system in the world to have passed the internationally recognized Gastec corrosion test.

The chimney size should be as recommended by the appliance manufacturer. Where there is a requirement for a flue diameter smaller than the appliance spigot, then the operational requirements of the appliance and the configuration of the flue must satisfy the flue sizing requirements of BS EN 13384-1 for single appliances.

Features and benefits:

Engineered spigot and socket joint.
Pronounced lead in edge.
Quick and easy assembly.
Pressure gasket on outer case protected by insulation.
Continuous insulation avoids thermal bridging.
Inner liner free to expand and contract.
No requirement for expansion joints.
