Danger!
Vaillant appliances are only system-certified if
genuine Vaillant flue pipes are used. Only use
genuine Vaillant flue pipes. Malfunctions can
occur if you use other accessories. These may
result in damage and injury. You will find a list
of genuine flue pipes in the Vaillant installation
manual for flue pipes. The CE mark is valid only
if the appliance is operated with Vaillant flue
pipes.

Termination of the flue pipe
The following information applies to both flue pipe sys-
tems.
a. The flue terminal must be located in such a position
that any flammable substances can be freely dissipat-
ed.
b. Water condensation (known as pluming) can also arise
at the terminal of the flue pipe. Installation sites
where these appearances may cause a problem should
be avoided.
c. If the flue terminal is less than 2 m above a balcony,
the ground or a flat roof that is accessible by persons,
a suitable protection guard should be fitted (manufac-
tured by Tower Flue Components, Tonbridge, TN9 1TB,
Model K3, plastic-coated).
