The following components are taken into consideration for the maxi-
mum flue lengths:
■
Balanced flue connection pipe D 0.5 m long.
■ 1 balanced flue bend 87º and 1 support bend 87º
or
■ 2 balanced flue bends 45º and 1 support bend 87º
Subtract other bends, tees and extension pieces from the maximum
length using the following values:
■ Balanced flue connection pipe 0.5 m long: 1 m
■ Balanced flue connection pipe 1 m long: 2 m
■ Balanced flue bends 45º: 0.5 m
■ Balanced flue bends 87º: 1 m
■ Balanced flue inspection tee: 1.5 m
Note
Observe the specifications regarding internal shaft dimensions (see
page 10).
Vitoladens in conjunction with solid fuel boilers
Routing a plastic flue adjacent to a shaft at risk of chimney fire from
soot (e.g. two draught chimney with wood burning stove) is generally
permitted. Subject to the design of the chimney top and the operation
of the condensing systems (open or balanced flue), fire regulations
specify different measures. Design the balanced flue terminals so that
flue gas will not be drawn into the air shaft in dangerous amounts and
that pressure fluctuations due to wind influence affect the balanced
flue shaft as evenly as possible.
For the essential steps, see the following sections:
Open flue operation or if the ventilation air is not supplied through
the shaft
For fire safety reasons, the top sections of flammable flue terminals
should not be made from flammable materials. The length of the flue
pipe made from non-combustible materials in the section protected
from heat radiation Lg must be at least 300 mm long. The length of the
external terminal pipe of the shaft cover must be at least equivalent to
the external diameter D of the internal flue pipe.
The standard shaft pack delivery (metal/PPs) includes a stainless steel
pipe (380 mm long). A stainless steel extension (380 mm long) is
available as an additional accessory.

possible.
