Additional Requirements For Stainless Steel Vent Pipe Material; Exhaust Vent Pipe Connection To Boiler - Viessmann Vitodens 100-W WB1B Series Installation Instructions Manual

Rigid Venting Systems Installation Instructions
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 31 and 32 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 31 and 32 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 (for models WB1B 26, 35 and
WB2B 19, 26, 35) and starter stainless steel adaptors
(supplied by others, see tables 31 and 32). 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 4.9.2010 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 label.
