Engineering information – balanced flue system
The maximum lengths identified in the table
under "Adjusting the flue pipe lengths" must not
be exceeded, otherwise incomplete combustion
can occur, resulting in damage to the boiler and
in particular moisture related damage to the
system.
If the CO content in the flue gas is higher
than 300 ppm (free of air), remove the cause;
otherwise do not continue to operate the
gas fired boiler, as there would be a risk of
flue gas escaping, resulting in the danger of
poisoning.
Wolf boilers are certified as one unit with the
original Wolf balanced flue system. Use only
original Wolf balanced flue systems. Using
alternative accessories can lead to incorrect
functions. Material losses and injuries cannot
then be prevented.
General information:
From a length of 2.5 m upwards, we recommend the installation of a condensate trap.
Calculating the flue length 60/100 mm
Calculated flue length = length of straight pipes + 1.0 m per 90° bend / tee + 0.5 m per 45° bend
Type C12x
Outside wall connection (balanced flue)
concentric horizontal system 60/100 mm
calculated pipe length min / max = 0.3 / 5.0 m
Type C32x
Roof outlet (balanced flue)
concentric vertical system 60/100 mm
calculated pipe length min / max = 0.3 / 5.0 m
Type C42x
Connection to a room sealed balanced flue
(balanced flue)
concentric system 60/100 mm
A+B<2m
Connection to a chimney;
ventilation air directly via the boiler or through a horizontal
concentric supply line (open flue)
concentric system 60/100 mm
