Single-WallStainless Steel

Chimney System

SW is a high quality factory-made single-wall flue system

comprising of a range of lengths, tees, elbows and associated

fittings and supports. The product is constructed from stainless

steel with simple crimp couplings for rapid site assembly and is

available in nine diameters from 100mm to 350mm.

SW is suitable for oil and gas fired industrial/commercial warm

air heating equipment where the flue gas temperature will not

exceed 300°C and where the flue system operates under negative

draught and dry conditions. SW is not suitable for pressure or

condensing application and in this case our Supra product should

be used.

Material Specification

Standard lengths and components are manufactured from

stainless steel type 430, 0.5mm.

PRODUCT INFORMATION

INTRODUCTION INSTALLATION

CONSTRUCTION

GeneralInstallation must be in accordance with local and national building

regulation. Where there is the possibility of accidental human

contact the SW product should not be used and consideration

should be given to a twin wall insulated product such as Nova

SM, alternatively please discuss your requirements with our

Technical Services Dept.

In all cases the SW product should maintain a distance of at least

four times the product diameter from any combustible material.

To prevent excess condensation of the flue gases and potential

freezing, it is not recommended that the SW product is used for

external runs, especially if being used on oil fired applications.

SFL would strongly suggest the use of SMW or Nova for this

application.

JointingAll lengths and fittings are designed to be installed with the female

socket / coupler uppermost. The male crimped spigot is pushed

firmly into the swaged female end and secured with a Locking

Band. To prevent leakage of rainwater into the flue at the joints

which may be exposed at roof level, a Change-Over section

is fitted. This component has a male crimp on both ends to

facilitate connection to the terminal.

SupportsSW must be independently supported with none of the weight

being taken by the components or by the appliance. Dependent

on the total height and the configuration of the flue system a

number of supports will be required.

Wall Support Brackets provide either initial or intermediate support

to the flue system and offer a 50mm clearance from the structure.

These should be used to take the vertical load of the chimney

system and should be used every six metres.

Support Plate & Camp provides vertical support where the

SW product passes through a non-combustible floor. This

component can take a vertical load of up to six metres of product.

Wall Bands provide lateral support for the flue system and are

designed to offer a clearance of 50mm from the structure and

should be used at three metre intervals. Wall Bands can also be

used to suspend either horizontal or inclined runs within the plant

room, however the distance between Wall Bands for horizontal

runs should be no less than 1.5m. Where used externally, the

stainless steel version should be used.

Wall Fixing Brackets provide lateral support. The Wall Fixing

Bracket can also be cut back on site to provide a clearance

between 50mm and 300mm. Where used for lateral support the

interval between Wall Fixing Brackets will depend on the length

of the extension. The maximum distance between brackets at

50mm clearance to structure is 3.0 metres, however for ever

100mm of extension, the interval between bracket must be

reduced by 1m.

Where the flue is free-standing above a roof and its height

exceeds 1.5m beyond the last support, a Guy Bracket in

conjunction with bracing rods, must be used

FlashingsWhere a flue penetrates a roof, a suitable flashing must be used

as detailed on page 6. A Storm Collar must be clamped and

sealed to the outer casing of the flue immediately above the

flashing.

TerminationsA number of terminals are available within the SW product. The

GC1 terminal is only suitable for gas and covers diameters from

100mm to 150mm. For gas appliances above this size, the

Storm Cowl with Mesh should be used. The Round Top and

Storm Cowl offer a greater degree of protection for exposed

locations, with the Storm Cowl offering the maximum protection.

A Change-Over section must always be fitted to the final length of

flue to facilitate connection of the terminal.

All lengths and components are of single wall construction with

vertical seams being lock formed or spot welded. The spigot

end of the flue is formed by roll swaging and crimping, whilst the

socket end is formed by roll swaging. All lengths and fittings push

fit together and the joint is completed by a Locking Band.
