5.6 Installing terminal sets for 60/100 mm
diameter air/flue systems
5.6.1 Minimum clearances for the flue gas terminal
You must comply with the minimum clearances for the flue
gas terminal that are defined in BS 5440, unless the boiler's
manufacturer has given approval to use shorter minimum
clearances that are not considered to be safety-critical.
Vaillant has reduced the minimum clearances for the flue
gas terminal and specifies this in the installation instructions
for the boiler. These are minimum clearances that are to be
used for all types of installation, except for the installation of
the variable terminal set (VTK).
If a variable terminal set is connected to horizontal flue pipe-
work, terminal clearances are reduced for the air inlet. The
terminal clearances on the "new" flue outlet at the end of
VTK remain unchanged.
On the VTK, the minimum clearances for the air inlet A, B
and C (→ Installation instructions for the boiler) to openings
(e.g. a window) are reduced to 150 mm. This means that
the terminal will be at the horizontal flue pipework when a
variable terminal set is connected to the air inlet and can
therefore be installed at a clearance of less than 300 mm
from a window opening or a ventilation tile.

air pipe to the floor.
Note
You cannot reuse the terminal as detaching
the terminal damages the latching lugs in
the terminal.

pipe.
