Rigid Venting Systems Installation Instructions

Vent Requirements - Stainless Steel

Additional requirements for stainless steel vent pipe material

Use special stainless steel venting system (UL/ULC listed
for category IV) for horizontal or vertical venting of the
Vitodens boilers.
See tables 18 and 19, and contact one of the suppliers
(see listing on right) to order.
Prior to installation, check that the correct single-pipe
vent parts were ordered and supplied.
See table 22 for special parallel/starter adaptor and bird
screen models required for your installation. In case of
discrepancies, contact original parts supplier.

Exhaust vent/air intake connection to boiler

The vent connection to the Vitodens boiler must be made
with the starter stainless steel adaptor (supplied by others
and/or parallel adaptor see table 22). The starter adaptors
are intended for a slip fit and slide into the parallel adaptor
with a gentle twisting motion.

Combustion air intake pipe:

If the venting system will use CPVC/ABS, PVC plastic
pipe for combustion air intake, a CPVC starter adaptor for
use on air intake connection to parallel adaptor must be
ordered from Viessmann (see table 22).
The bird screen for the air intake termination elbow must
also be ordered from Viessmann.
Note: The Vitodens boiler has passed the zero inches vent
clearance to combustibles testing requirements
dictated by the Harmonized Standard ANSI Z21.13.
CSA 4.9.2010 and therefore is listed for zero
clearance to combustibles when vented with a single
pipe special venting system. The zero inches vent
clearance to combustibles for the Vitodens boiler
supersedes the clearance to combustibles listing
that appears on the special venting system marking.
