Specflue DW30
Product information
Specue DW30 has been specically designed to
meet the requirements of today’s clean burning
multi-fuel appliances. The system provides an
economical and robust twin wall insulated stainless
steel chimney system oering high material
specication, design, manufacturing quality,
thermal performance and ease of installation. It is
suitable for negative draught conditions where the
maximum continuous ue gas temperature does
not exceed 600°C and is soot re rated at 1000°C.
Specue DW30 is available in 130 and 150mm
internal diameters and consists of adaptors,
lengths, ttings, supports and restop components.
Each chimney element is fabricated with a fully
welded 316L stainless steel inner liner and a
stainless steel outer case. It is also available in
a Matt Black nish as indicated by the MB sux
on the part number. The 30mm annulus between
the two walls is insulated with a high thermal
performance pressure injected or pipe section
mineral wool to a mean density of 170-190kg/
m3. The jointing system is a simple push t
male and female joint with the male end pointing
upwards. The 70mm of engagement oers a strong
structural joint with the locking band provided.
Specue DW30 is designed to be used both
internally and externally as a fully supported
structure, and must be installed in accordance
with National and Local Building Regulations and
Standards.

The chimney diameter size should be as
recommended by the appliance manufacturer and
in accordance with current building regulations.
Warranty
Specue DW30 carries a 25 years conditional
warranty.
General Design Considerations
Chimney Diameter/Height
The internal diameter of the chimney must conform
to the requirements of the heating appliance
manufacturer’s instructions, and should not, under
any circumstance, be less than the appliance
outlet. The height of the chimney will depend on the
building structure, however it is recommended that
not less than 4.5 metres should be considered the
minimum chimney height from the appliance
to termination for solid fuel applications. For
further clarication refer to Document J of the
DOE Building Regulations, Section F of the
Building Standards (Scotland) and Section L
of the Building Regulations (Northern Ireland).
Chimney Route
The chimney system should remain as straight as
possible through its vertical run but should it be
necessary to oset the chimney there should be
no more than 4 changes of direction of a maximum
45°. It is also recommended that a vertical rise of
600mm should be allowed immediately above the
appliance before any change of direction.
Chimney Support
The chimney must be adequately supported
throughout its length and the Specue DW30
product oers a range of lateral and vertical
support components to undertake the safe
installation of the chimney system.

2
Provision for Sweeping
and Cleaning
Adequate provision should be made for
inspecting and cleaning the chimney system.
This is particularly important for solid fuel
applications. Specue recommends that
chimneys are swept at least once a year.
At the time of sweeping it is important that a
visual inspection of the ue is undertaken.
Combustion Air Requirements
All heating appliances need combustion air to
work eciently and safely. It is essential that the
appropriate permanent air supply, as required
by the appliance manufacturer and Building
Regulations is provided into the room where the
appliance is situated. Always refer to the appliance
manufacturer’s recommendations and Building
Regulations before installation.
Floor Penetration Components
Where the Specue DW30 product is used on solid
fuel or oil appliances and the ue gas temperature
exceeds 250°C, the clearance at oor/ceiling void
must be established using the ventilated support
plate and ventilated re shield, ensuring that no
joints are made within the ceiling void. A magnetic
re shield cover is also available used in conjunction
with the ventilated re shield to improve aesthetics.
When connecting to a single wall ue pipe,
Specue DW30 must project below the appliance
room ceiling by a minimum of 425mm before a
connection is made. All support components
oer a 60mm clearance to combustible material
that must be maintained at all times.
Appliance Connection and
Condensate Removal
The Specue DW30 adaptor should be used
to facilitate connection from the appliance to
the chimney. It is recommended that the joint
between the adaptor and the appliance/ue pipe
is securely caulked and sealed with bre rope/
tape and re sealant. Any ue pipe connection
to the chimney must be made in the same room.
Condensation removal should be determined by
each individual application. The system must be
designed to facilitate future appliance removal.
Note: In the UK, 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 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).
Adjustable Pipes
The Adjustable Pipe consists of two sections which
telescope together. Both sections are insulated, and
the component is supplied with additional insulation,
which will need to be added to the annulus on
site depending on the desired nished length. The
overlapping section should be secured with self
drilling screws. Each end of the adjustable pipe is
secured with locking bands in the normal manner.
The adjustable pipe does not load bear so always
use a wall support or a support plate immediately
above this component when vertically applied.
Handling
The product is relatively easy to handle, but care
should be taken when holding, tting or assembling
any part of the system. Users are advised to wear
gloves to avoid injury or any sharp exposed edges.
Data Plate
It is a regulatory requirement that a data plate
is to be completed, positioned and secured
by the installer where a hearth, replace, ue
or chimney is provided or extended. The data
plate provides essential information regarding
the performance, specication, designation and
installation of the chimney system. The data
plate is to be completed by the installer using an
indelible ink and securely xed in an unobtrusive
but obvious position. Acceptable xing positions
would be next to the electricity consumer unit,
water supply stop cock or by the hearth.
Carbon Monoxide Alarm
Approved Document J of the Building
Regulations (Section 2.34) state that all new and
replacement solid fuel appliances must be tted
with an approved carbon monoxide alarm.
