1.
Set the telescopic wall duct to the correct length.
–
Note that the
TOP
symbols at both ends must point
upwards.
Danger!
Risk of poisoning due to escaping flue
gas.
Flue gas can escape if a flue gas pipe is dam-
aged.
▶
Only use the self-tapping screw provided.
2.
Secure the air pipes to each other by screwing the over-
lapping air pipes together using the supplied self-cutting
screws
(1)
on the underside.
3.
Seal the gap on the telescopic air pipe using the sup-
plied adhesive tape

3.
Pull the wall duct out to the required depth.
4.
Use the safety screws to secure the wall duct.
–
Use at least three of the six holes
(1)
that are avail-
able in the terminals to secure the flue pipe.
5.
Install the wall collar.
6.
Before you install the boiler, check that the wall duct is
safely secured in place.
7.
Seal the installation gap using a suitable material (e.g.
mortar).
8.
Install the boiler (

Installing terminal kits for 60/100 mm
diameter air/flue gas systems
5.4.1
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 kit (VTK).
If a VTK is connected to a horizontal flue gas pipe, terminal
clearances are reduced for the air inlet. The terminal clear-
ances on the "new" flue outlet at the end of VTK remain un-
changed.
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 gas pipe when a VTK 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.
