AccordingtoTRGI:
Connection to a moisture-resistant balanced ue
chimney(LAS),uegaschimneyoruesystem
Chimneysanduesystemsmustbecertiedforcombustion
equipment in accordance with local Building Regulations (CE
/DIBTcertication).Dimensioningiscarriedoutusingthecal-
culationtablesaccordingtotheuegascategory.Inaddition
to the boiler connection bend or tee piece, up to two 87°/90°
diversions may be installed. Approval is required for positive
pressure operation.
Connection to a moisture-resistant balanced ue
chimneytypeC43x
Straightbalanceduesmaybeupto2.0mlong,wheninstall-
ingthesysteminabalanceduechimney. In addition to the
boiler connection bend, up to two 87° bends may be installed.
Thebalanceduechimneymustbecertied[inGermany]by
the DIBT - Deutsches Institut für Bautechnik and must also
be approved for condensing operation with positive pressure.
Connectiontomoisture-resistantuegaschimney
orauegassystemtype,B33foropenueoperation
Straight balanced ues must be no longer than 2 m when
connectingthesystemtoauegaschimney. In addition to the
boiler connection bend, up to two 87° bends may be installed.
TheuegaschimneymustbecertiedbyDIBT[Germany]
and must be approved for condensing operation.
If necessary, obtain the connection piece from the chimney
manufacturer.
The air apertures to the boiler room must be completely free
from obstruction.
Connectiontomoisture-resistantue,typeB23for
openueoperation
Thestraight,horizontaluemustnotbelongerthan3m.
In addition to the boiler connection bend, up to two 87° diver-
sionsmaybeinstalledintothehorizontalue.
For this option, observe the regulations concerning ventilation
for boiler rooms acc. to DVGW-TRGI.
Connectionto moisture-resistant ue, type C53,
C83x,forroomsealedoperation
Thestraight,horizontaluemustnotbelongerthan3m.For
horizontal air supply pipes, a maximum length of 3 m is recom-
mended.Observethespecialrequirementsforuesthatare
not surrounded by combustion air acc. to DVGW-TRGI 2008
and all locally applicable combustion regulations.
Connectionto a combustion air and uesystem
typeC63xthatisnottestedtogetherwiththegas
combustionequipment
Original Wolf components are designed for long term use,
are designated with the DVGW quality seal and are designed
for use with Wolf gas condensing boilers. If using third party
equipment that is only DIBT or CE certied, the installer is
responsible for the correct sizing and correct function of the
system. Faults, material losses and injuries resulting from in-
correct pipe lengths, excessive pressure drop, premature wear
withescapinguegasandcondensateorincorrectfunction,
e.g. through components working themselves loose, are ex-
cluded from our warranty if third party equipment that is only
DIBT/CEcertiedisused.Straightbalanceduesmustbeno
longer than 2 m, when connecting the system to a combustion
air supplyandaseparateue.
In addition to the boiler connection bend, up to two 87°/90°
bends may be installed.
If the combustion air is drawn from the duct, the duct must be
free from contamination.
