Installation of Support System
The venting system must be securely
supported by a support system suitable
for the weight and design of the
materials employed.
Contact your vent material supplier for
more information specific to your
installation.
Supports
Supports are used to transfer the
weight of an installation to the building
structure. There are different types of
supports and their capacity varies with
each type and diameter.
The following support types are
available at your local vent material
supplier...
H anchor plate
H wall support
H roof support
H floor support
H suspension band (hanger).
In addition to the support types listed
above Viessmann offers mounting clips
(see
fig. 25 and fig. 26) which can
be used in conjunction with the above
support types to support the weight of
the venting system. Please contact
Viessmann to order.
Vertical vent systems with horizontal
sections must have the joints in these
sections secured with supplied sheet
metal screws
(see fig. 25) to
prevent the system from sagging.
The 4”/101.6 mm screws
supplied
with the mounting clip provide wall or
ceiling support for a
H minimum distance of 2”/50.8 mm
H maximum distance of 3¼”/82.5 mm
(see fig. 26).
If a longer support system is required
use brass adaptors M8 x

Bracing
Contact your local vent material
supplier for more information specific
to your installation.
Braces are required to stabilize an
installation. There are different types
and their use and spacing vary.
The following types of braces are
available at your local vent material
supplier...
H wall band
H wall band extension
H guy wire band
H roof brace.
Ensure that the venting system is
properly supported; the Vitodens
100-W boiler is not designed to
support the weight of the venting
system.
