Installation Of A Balanced Flue System - Wolf COB Installation Instructions And Technical Manual

Installation of the balanced flue system
For flues and concentric balanced flue systems,
NB
use only original Wolf components.
Please observe the technical information
regarding balanced flue systems prior
to installing the flue or the balanced flue
connection.
As regulations in the individual Federal States
[Germany] differ, we recommend consulting the
relevant authorities and local flue gas inspector
prior to installation.
In the case of COB-15/20/29 the enclosed flue
NB
gas measuring nipple must be mounted on the
air/flue gas connecting piece of the boiler.
Alternatively, the flue gas measuring nipple
can be mounted immediately behind that in a
horizontal position directly on the 87° elbow
fitted to the boiler. When doing this, however,
care must be taken that the air/flue gas duct is
installed above the appliance in such a way that
it is possible to remove the displacer (minimum
distance above COB-15/20/29 is 30 cm; in the
case of the COB-40 this is 40 cm).
The local flue gas inspector must have clear
NB
access to the flue gas test nipples.
Flue connections are created using couplings and gaskets.
Always arrange couplings against the condensate flow
direction.
The balanced flue should be installed with
a slope of at least 3° (6 cm/m) to the oil
condensing boiler. Spacer brackets should be
fitted to secure the equipment in position.
In the worst case scenario, a smaller slope
for the balanced flue may lead to corrosion or
operating faults.
Generally bevel or deburr trimmed flues to ensure
NB
a gas tight installation of pipe joints. Ensure that
gaskets are properly fitted. Remove all contamination
prior to installation - never fit faulty parts.
Between the flue terminal and the roof surface, there must be
a distance of at least 0.4 m.

Bei COB-15/-20/-29 muss der beiliegende
Achtung
A b g a s - M e s s s t u t z e n a u f d e m L u f t - /
Abgasstutzen des Kessels montiert werden.
Alternativ darf der Abgas-Messstutzen
auch unmittelbar nach dem dann direkt
auf dem Kessel aufgesteckten 87°-Bogen
waagrecht montiert werden. Hierbei ist aber
zu beachten, dass die Luft-/Abgasführung
so über dem Gerät zu verlegen ist, dass ein
Ausbau der Verdränger gewährleistet ist
(Mindestabstand über COB-15/-20/-29 ist
30cm; bei COB-40 ist dieser 40cm).
