Schiedel ICS

ICS Twin Wall Insulated Chimney System

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

ICS

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.

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.

The video below shows how quickly and safely you can convert ICS to ICS Plus using a Viton gasket.

ICS 5000

For larger commercial and industrial applications of ICS in diameters 300mm to 700mm please refer to our separate sales brochure. For higher pressure applications up to 5000Pa e.g. generators, combustion and process equipment, please see the commercial brochure.

A multi-functional twin insulated venting system for use on a wide range of heating appliances, stand-by power engines, CHP and service ducting

Features

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.

ICS Double Wall Adjustable Starter Section

NEW ICS DOUBLE WALL ADJUSTABLE STARTER SECTION

Hot on the heels of the great success of our Award-Winning ICID Plus Double Wall Adjustable Starter Section, we’ve introduced the ICS version of the product, which is an easy and quick way of disconnecting a stove for inspection.

The Starter Section is available in two effective lengths: 1025mm and 600mm and is exceptionally easy to install and remove for servicing. The process for the ICS version matches the ICID version. Simply inserting a male spigot of the liner into the appliance spigot, sealing it, insulating it and then sliding down the case to cover the stove spigot. Removal for servicing and re-installation is just the reverse.

Bungalow Firestop Kits

ICS Twin Wall Insulated Chimney System Installation

A ventilated fire stop plate is not required for single storey bungalows with a ventilated loft space. Schiedel has developed a solid fire stop kit that can be fitted even more unobtrusively in the ceiling.

The fire stops can be used with Eco ICID and ICS twin wall flues and are available in three options:
one piece round, two piece round and one piece square.

These unventilated fire stop plates may only be used on a combustible ceiling in a bungalow where there is a minimum 60mm distance to combustibles where the chimney penetrates the ceiling area and where the roof space above the ceiling is open and ventilated. Within the roof space, a protective wire mesh framework must be built around the chimney to ensure the minimum 60mm distance to combustibles is maintained.

Magnetic Firestop Cover Plate Kit

ICS Twin Wall Insulated Chimney System Installation

This new addition to the ventilated firestop range has been introduced an aesthetic cover plate kit, which fastens to the standard ventilated firestops using the magnets which are provided in the kit along with the cover plates. Kits are available in plain finish, painted matt black to RAL 9005, or painted matt white to RAL 9016 to match the firestops.

Magnetic firestop cover plate kits for use exclusively in combination with stove starter pipes and ventilated firestop plates.

Load Bearing Roof Support

ICS Twin Wall Insulated Chimney System Installation

The roof support is supplied as a kit complete with two side plates for fixing to the roof trusses, a band to give lateral support to the chimney as it passes through the roof, and 3 self tapping screws, which are secured to the chimney through the band to give a load bearing capacity. When the plates are installed above the roof trusses as in Fig.1 the maximum number of pipes, which may be suspended from the roof support is 6 x 1m pipes.When the plates are attached below the trusses as in Fig.2 the maximum number of pipes, which may be suspended is 4 x 1m pipes.

The band should be lowered down over the top of the Eco ICID pipe, and positioned so that the the side plates are resting on top of the roof trusses as in Fig.1 or below the roof trusses in the case of Fig. 2 .The recommended position is always as per Fig.1 where circumstances allow this solution.
The band should then be tightened using the nut and bolt provided.
Using the holes pre-drilled in the roof support band, drill 3mm holes in the outer case of the chimney section (drill bit should be set for a depth no greater than 10mm to avoid any damage to the liner of the chimney)
Use the self tapping screws provided to secure the clamp band to the outer casing of the chimney section.

Please note: It is the responsibility of the installer to ensure that the joist to which the roof support is being attached is load bearing and capable of withstanding the weight of the system being installed.

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.
