Installation

Mandatory Requirements

Connection to an appliance which is not connected tothe fuel supply, may be carried out by a competent person. However,connection to an appliance that is connected to the fuel supply must becarried out by a CORGI (gas) or OFTEC (oil) registered installer.

Theflue system must be installed to comply with Building RegulationsDocument J (in England, Wales & Northern Ireland) Regulations forScotland. The installation must also comply with BS7566 pts 1,2,3,4 foroil flues and BS5440 pt 1: 2000 for gas flues up to 70kw.

Jointing

The joint is locked by rotating the upper sectionclockwise. To secure the joint, the locking band supplied with thefemale end of all components must be used. To allow alignment, thefemale section of the locking collar on tees and elbows have nolocating flutes. For this reason these joints MUST be secured using thelocking band.

For condensing applications a lip seal gasket must befitted in the bead of the projecting liner spigot of every joint. Thegasket should be fitted dry and lubrication applied to the internal ofthe socket into which it is to be assembled. 

Adjustable Length

An ICID adjustable length allows adjustment from 75mm up to 250mm.Assembly is achieved by fitting the adjustable length over thepreceding pipe. Remove insulation as necessary and secure when desiredlength is achieved using jointband supplied. The adjustable is notload-bearing, therefore adequate support must be provided immediatelyabove.

Connection to Appliance

Always use an appliance connector, sealed using fibrerope and fire cement or high temperature sealant. The inner linershould not project below the appliance outlet spigot and can be cut tolength if required.

Appliance Removal

Use of a pipe length and an adjustable length immediately above theappliance enables removal of the appliance later without dismantlingthe full system.

Painting

If required to be painted, simply clean the surface with a solventcleaner (White Spirit), apply a coat of primer and a top coat of hightemperature paint e.g. enamel. Extreme care must be taken when cleaningwith solvent to ensure that it does not come into contact with theinsulation within the cavity.

Recommended distances to combustibles

In accordance with building regulations it is essentialthat the required distance to combustible materials is maintainedthroughout the chimney system. For gas and oil this is 50mm and forsolid fuel 75mm. ICID support components provide this as standard. 

Support Components

The weight of a chimney system is considerable and requiresindependent support. No weight should be taken by the appliance. A wallsupport at the base of the stack will support up to 10m of chimney, orin an inverted position, up to 15m. Wall supports can then be used asan intermediate support every 10m thereafter.

Alternatively, oninternal systems the weight is held by using a support plate and clampfixed on top of the first floor/ceiling joist. A Firestop plate is alsorequired fixed to the ceiling below. In a normal house, when passingthrough the second floor the only requirement is two firestop platesbecause the system is adequately supported at first floor level.

Refer to load bearing table below for full details of maximum loadings.

Wall brackets androof brackets are not load bearing and give lateral support only. Wallbrackets should be fitted every 3m and at any offsets to ensure thesystem is rigidly supported.

Where the flue is free standingabove the roof and its height exceeds 1.5m beyond the last support orthe roof a guy wire bracket must be used, and every 1.5m thereafter.Alternatively, a height of up to 4m can be achieved unsupported withthe use of an extended locking band at the joint immediately below andevery joint above the roof level.
