Flue pipe

Danger!
Vaillant appliances are certified only for use
with genuine Vaillant flue pipes. Only use genu-
ine 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.

Flue termination

The following details refer to both flue systems.
a. The terminal must be located where the combustible
substances can escape freely at all times.
b. A plume of water vapour will sometimes be visible
from the flue terminal. Positions where this could be
a nuisance should be avoided.
c. If the terminal is fitted less than 2 m above a balco-
ny, above ground or above a flat roof to which peo-
ple have access then a suitable terminal guard must
be provided and fitted (made by Tower Flue
Components, Tonbridge, TN9 1TB, Model K3, plastic
coated).
