Air/Flue Pipe - Room Sealed, Combustion Air From The Shaft - Vaillant Flue pipe VKK SERIES Installation Manual

4 System - certifi ed fl ue pipe - open fl ued
The following describes the four possibilities for flue
pipes:
- flue pipes for room sealed operation, combustion air
from the duct
- flue pipes for room sealed operation, combustion air
through the external wall
- flue pipes for room sealed operation, combustion air
and flue gas dispersal above the roof
- flue pipes for room sealed operation, combustion air
through the external wall, flue gas pipe on the facade
a Caution!
Observe the maximum pipe lengths given in the
individual sections. Pipe lengths which are too
long will lead to operational malfunction of the
condensing boiler.
Caution!
Note whether an increased heat transmission
resistance of the exhaust gas pipe is required
by running through the cold section. Otherwise
it may cause the formation of ice in the ex-
haust pipe at low temperatures.
Caution!
The air supply must be installed in such a way
that no rainwater can enter the boiler. Rainwa-
ter ingress can cause a short-circuit of electri-
cal components and can cause corrosion in the
unit.
Caution!
Danger of fire!
Outside the ducting, the exhaust pipe must be
at least 5 cm away from combustible building
components. This does not apply to exhaust
gas pipes which permit less separation distance
in accordance with their classification.
Caution!
The distance between the flue terminal and the
roof must be at least 1 m, to avoid combustion
problems caused by wind pressure.
