ICS 5000 Flue System

Multi-functional twin wall insulated venting system for use on heating appliances, stand-by gensets, CHP and service ducting.

PRODUCT DESCRIPTION

ICS 5000 is 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, CHP systems and service ducting.

ICS 5000 comes with a high quality specification as standard with a 316L Grade Stainless steel liner, high performance mineral blanket insulation and a bright annealed 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.

CORROSION RESISTANCE

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 recognised Gastec corrosion test.

CHIMNEY DIAMETER

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.

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.
