Vent Requirements - Stainless Steel; Additional Requirements For Stainless Steel Vent Pipe Material - Viessmann Vitodens 200-W WB2B Series Installation Instructions Manual

Vitodens Rigid and Flex Venting Systems Installation

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 on page 36, and contact the suppliers to order.
Prior to installation, check that the correct single-pipe
vent parts were ordered and supplied.
See table on page 35 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 on page 35). 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 on page 35).
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 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 label.
