Appliances

PRODUCT INFORMATION

The Supra chimney system range is specifically designed to
meet the demands of the latest high efficiency condensing
heating appliances. Supra 80mm - 350mm is supplied
complete with factory fitted and bonded elastomer seals,
offering peace of mind and reduced installation time for the
installer.

INTRODUCTION

Supra is a single-wall pre-fabricated stainless steel flue system,
primarily designed for gas and kerosene (28Sec) oil fired
appliances, which produce condensates and positive pressure
conditions as a function of their operation, such as high efficiency
condensing appliances.

DESCRIPTION

Supra is manufactured in 13 diameters ranging from 80mm to
600mm and consists of a range of lengths and fittings which
simply push-fit together, and which are secured with a Locking
Band. The entire system is manufactured from corrosion resistant
grade 316L (1.4404:X2CrNiMo 17-12-2) stainless steel and is
manufactured using a fully welded construction and precision
formed close tolerance joints.

Supra has been specifically designed for condensing applications
and product sizes from 80mm to 350mm inclusive are supplied
complete with factory fitted and bonded elastomer seals.

Product sizes from 400mm to 600mm inclusive are manufactured
from 1mm 316L material. As these diameters can be used for
re-lining existing masonry stacks, they are provided without seals
fitted as standard. Where seals are required in these diameters,
they need to be purchased and retrofitted on site.

The Supra product is available with a wide range of support
components that cater for both lateral and vertical structural
loading of the product. SFL does not recommend any other
system of support being used with the Supra product, unless
approved by SFL prior to installation.

Application

The standard Supra product is primarily designed for internal
applications and for use on high efficiency gas / kerosene fired
condensing appliances and for applications where the chimney
could be under positive pressure conditions not exceeding 200Pa
at a maximum flue gas temperature of 200°C.
Supra can also be used as a rigid chimney liner within a masonry
chimney.

When fluing condensing appliances and where the chimney
is external to the building, there is a risk that the condensates
could freeze. In such cases, SFL would recommend that a twin
wall insulated product such as Nova SM is used to prevent this.
Regulations now require all domestic external flue runs over 3m are
to be made from twin wall insulated product manufactured with a
stainless steel liner.

Care should be taken where there is a risk of accidental human
contact with Supra. Although most condensing appliance produce
flue gas temperatures in the region of 30-50°C, it is possible that
in non-condensing mode the flue gases can achieve much higher
temperatures. For instances where the flue gas temperature of
the appliance can rise above 70°C and there is the possibility of
accidental human contact, a twin wall insulated product such as
Nova SM should be used.

Quality

All components are manufactured under a quality assurance
scheme, certificate No. FM 557622, administered by British
Standards in accordance with BS EN 9001: 2008. In addition
SFL operate a CE approved factory production control system as
required under the Construction Products Directive 93/68/EEC.

Installation / Regulations

Connection to an appliance which is not connected to the fuel
supply, may be carried out by a competent person. However,
connection to an appliance that is connected to the fuel supply
MUST be carried out by an approved and registered heating
engineer, e.g. Gas Safe, HETAS (Solid Fuel) or OFTEC (Oil).

The Installation of the Supra product must be in accordance with
local building regulations and associated National Standards and
Code of Practice. Relevant standards are as follows:-

Document J - DOE Building Regulations
Section F - Building Standards (Scotland)
Section L - Building Regulations (Northern Ireland)
Solid Fuel & Oil Fired Appliances: BS EN15287-1:2007
Domestic Gas Installations: BS5440: Part 1: 2008

SUPRA JOINTING DETAILS

Fig 1

Where Supra is used to reline an existing stack, it is imperative that
the product is not supported by suspending from the top of the
stack. In all instances the liner must be lowered down the stack
using a Support Length at the bottom. Location Bands must
then be used at intervals not exceeding 3.0 metres. The Location
Bands are to be secured underneath a joint and are designed
to centrally locate and brace the system when lowered into an
existing chimney or shaft. When required, the Location Bands
can be manufactured to bespoke dimensions provided by the
customer to suit the required chimney / shaft dimensions.

For condensing (WET) applications it is important that horizontal
sloping runs are angled not less than 3° to the horizontal where
head room is limited, but preferably 5°. Various components are
available to facilitate either a 3° or 5° incline from the horizontal.
Drainage components MUST be used strategically within the
system to facilitate the removal of condensation, see Fig 3.
Above 350mm where Supra is used on condensing applications,
Elastomer Seals must be fitted and preferably bonded to the
product. Prior to making the joint, ensure that both mating ends
are clean and free of dirt and apply a generous amount of SFL Seal
Lubricant around the face of the seal to aid installation.

Commercial Applications

The Supra Product is suitable for commercial applications up to
and including 600ID. Due to the complexity of most installations,
SFL can manufacture to order bespoke components including
special angled elbows, tees and multi-inlet manifolds. Please
forward your requirements complete with detailed dimensioned
drawing to SFL Technical Department who will assess your
requirements.

SFL also employ state of the art software to model the
thermodynamic and flow characteristics of the proposed system,
allowing the most economic system design to be achieved. All
designs are calculated in accordance with EN 13384 parts 1 &

2. SFL can also offer advice on the Clean Air Act requirements
and calculate chimney heights to the requirement of the Clean Air
Act Memorandum. For further information please contact SFL
Technical Department.

Elastomer Seal (P1 / W Applications)

The Elastomer Seal is located in the recess of the female end of
the Supra chimney system as detailed in Fig 1. Product sizes from
80mm to 350mm are supplied complete with the Elastomer Seal
factory fitted and bonded. Above 350mm, Joint Seals must be
ordered separately. Where Supra is being used for condensing
(WET) / positive pressure (P1) applications up to 200Pa at a
maximum flue gas temperature of 200°C, Elastomer Seals MUST
be fitted at each joint within the system.
Note: Joint Seals are only suitable for gas and 28Sec (Kerosene)
applications within the above limits.
Where Elastomer Seals are being used, the chimney system must
be installed with a minimum of 3° or preferably 5° incline to the
horizontal to ensure adequate back drainage of condensation.
Failure to maintain an adequate incline and lack of drainage
component in the system may lead to premature failure of the
product / seals.
