Flue installation

The only flue systems that may be used are those supplied by
Boulter Buderus. The flue system must be installed in
accordance with the requirements of BS.5440:1. 2000.
Standard 100 mm flue systems
The standard concentric flue system provides for a max.
horizontal straight length of upto 7.5 m (see subsection 1.3.3).
Full instructions for fitting this flue are in subsection 1.7.2:
"Installation of the horizontal flue" on page 15.
IMPORTANT
Any horizontal flue system fitted to a
condensing boiler must be inclined towards the
appliance at an angle of 3% (30 mm per metre
length) to prevent condensate dripping from
the flue terminal.
This means that the clearance above the
appliance must be increased to match the duct
length. See figure on page 9.
1.7.1 Connecting the vertical flue gas duct
Fit the vertical flue gas duct (fig. 8) onto the appliance flue
connector.
For remaining installation of the vertical flue assembly,
refer to the relevant installation instructions.
1.7.2 Installation of the horizontal flue
The standard 100 mm diameter horizontal flue system is
siutable for lengths upto 560 mm (see fig. 10).
For longer flue runs upto 7.5 m, extension air/flue ducts are
available (see page 12, table 3).
NOTE
Use the wall-mounting template to help you
mark the position of the side flue opening
Subject to modifications resulting from technical improvements!
