Installation sequence
Mounting the boiler and making connections
Balanced flue connection
General installation information
Note
■ The boiler may only be operated with
a balanced flue system of
7 60/100 mm.
■ The balanced flue system must be
at least 1 m long, incl. 90° bend.
!
Please note
If a single flue pipe is used, the
boiler has no protection against
splashing water.
Only connect a concentric bal-
anced flue pipe or balanced flue
bend of 7 60/100 mm to the
boiler.
Design
Prior to installation, check that the max-
imum possible pipe length of 5 m will
not be exceeded.
Flue gas temperature protection
The flue pipes are approved for flue
gas temperatures up to 120 °C.
22
(cont.)
The shutdown threshold of the integral
flue gas temperature sensor is 110 °C
maximum, so that the maximum per-
missible flue gas temperature cannot
be exceeded. This shutdown threshold
cannot be changed.
Installation information
■ Keep flue gas routes short and with
the fewest number of bends possible.
■ Check whether the gaskets in all
female connections are correctly
seated.
■ Use only the special gaskets supplied
with the boiler.
■ Plug-in female connections in the flue
must always point in the flow direc-
tion.
■ Only use the components supplied
with the PPs flue system.
■ Push the pipes into each other with a
slight twisting motion.
■ Balanced flue pipes can be trimmed
in their assembled state.
Certification of the balanced flue
system
The balanced flue system is CE desig-
nated and approved (see Vitodens flue
systems technical guide).
