3.0 FLUE DESIGN
3.01 The following standards are relevant to the
construction, installation & testing of flue systems.
BSEN 14471 Plastic Chimneys –
requirements and test methods
BSEN 1856-1 Metal Chimneys – Requirements
BSEN 1859 Metal Chimneys – Test methods
BS 6644 Installation & Maintenance
of gas fired hot water
boilers 70kW – 1.8MW
3.0.2 The Flue Stack must be specified by a Flue Specialist
3.0.3 Design of the connecting flue spigot must refer to the
dimensions of the mating collar (Fig 3.1).
3.0.4 The Polypropylene header and EPDM seal are certified
to BSEN 14471.
3.0.5 Integrity of the flue joints and safety of operation must
be proven by the installer.
3.0.6 The flue resistance at ‘A’ in Figure 3.2 is not permitted to
exceed the maximum static pressure specification [Pmax]
quoted in Table 3.3 when operating at the maximum
capacity.
IMPORTANT: LEAKAGE OF FLUE PRODUCTS INTO THE ROOM WILL DEPLETE
THE OXYGEN LEVEL & INHIBIT SAFE COMBUSTION.
3.0.7 The flue route should be planned to enable the least
directional change, one elbow is recommended as
depicted in Figure 3.2.
3.0.8 The flue pipe diameter must be at least 200mm, larger
diameters will permit longer flue length.
3.0.9 The flue material must be suitable for condensing
operation.
3.0.10 The terminal guard must prevent the ingress of objects
greater than 15mm diameter to comply with EN15502.
3.0.11 The Flue Terminal design should be selected to create the
least resistance and not compromise the potential flue
length. A wire mesh type is recommended with a
14mm grid.
3.0.12 Rain ingress may be ignored as the header design
enables excess water to be discharged through the
condensate drain.
