Prior to installation, check that the correct single-pipe
vent parts were ordered and supplied.
See tables 31 and 32 for special stainless steel singlepipe 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
31 and 32). The starter adaptors are intended for a slip
fit and slide into the boiler adaptor with a gentle twisting
motion.
IMPORTANT
For exhaust vent pipe material:
Do not use any other vent material.
Do not use galvanized pipe, plastic pipe and/or chimney
liners of any kind.
WARNING
The use of vent material other than stainless steel,
positive pressure vent pipe and fittings can cause
property damage, severe personal injury and/or loss
of life.
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.
