Connection to a moisture-resistant balanced flue
chimney type C43x
Straight balanced flues must be no longer than 3 m when
connecting the system to a balanced flue chimney. In addition
to the boiler connection tee, up to two 90° diverters may be
installed.
The balanced flue chimney must be CE-designated.
Connection to a moisture-resistant flue gas chimney or a
flue system type B33 for open flue operation
Straight balanced flues must be no longer than 3 m when
connecting the system to a flue gas chimney. In addition to the
boiler connection tee, up to two 90° diverters may be installed.
The flue gas chimney must be CE-designated.
If necessary, the flue outlet should be obtained from the
chimney manufacturer.
The air apertures to the boiler room must be completely free
from obstruction.
Connection to a moisture-resistant flue type B23 for open
flue operation
The straight, horizontal flue must be no longer than 3 m. In
addition to the boiler connection tee, up to two 90° diverters
may be installed in the horizontal flue.
The flue gas chimney must be CE-designated.
Connection to moisture-insensitive flue gas line on double or multiple-flue chimneys (shaft)

Connection to a moisture-resistant flue type C53, C83x
for balanced flue operation
The straight, horizontal flue must be no longer than 3 m.
For horizontal air supply pipes, a maximum length of 3 m is
recommended. Observe special requirements for flues that are
not surrounded by combustion air in accordance with locally
applicable combustion regulations.
Connection to a combustion air and flue system type
C63x that is not tested together with the oil combustion
equipment
Original Wolf components are designed for long-term use and
are matched for use with Wolf oil condensing boilers. When
using CE-designated third party equipment, the installer is
responsible for the correct sizing and perfect function of such
systems. Faults, material losses and injuries resulting from
incorrect pipe lengths, excessive pressure drop, premature
wear with escaping flue gas and condensate or incorrect
function, e.g. through components working themselves loose,
are excluded from our warranty if non-approved third party
equipment is used.
Straight balanced flues must be no longer than 3 m, when
connecting the system to a combustion air supply and a
separate flue.
In addition to the boiler connection tee, up to two 90° diverters
may be installed.
The chimney must be free from contamination if the combustion
air is drawn from the chimney.
