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

Vitodens Rigid and Flex Venting Systems Installation
General Installation Information

Additional requirements for stainless steel vent pipe material

Use a special stainless steel venting system (UL/ULC
listed for category IV) for horizontal or vertical venting of
the Vitodens boilers.
See tables on page 58 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 tables on page 58 for special stainless steel single-
pipe vent starter adaptor, coaxial increasers and bird
screen models required for your installation. In case of
discrepancies, contact original parts supplier.

Exhaust vent pipe connection to boiler

The vent connection to the Vitodens boiler must be made
with a coaxial increaser (WB1B 26, 35, WB2B 19, 26,
35, B2TA 19, 35, B2HA 19, 28, 35 models) and starter
stainless steel adaptors (supplied by others, see tables
on page 59). The starter adaptors are intended for a slip
fit and slide into the boiler adaptor with a gentle twisting
motion.
Note: For stainless steel exhaust vent system, the
minimum pipe diameter is 3 in. (76 mm).
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.
