Single Wall Venting (Room Air Dependent)
General Installation Information
Additional requirements for stainless steel vent pipe material
Use an AL29-4C® special stainless
steel venting system (UL/ULC listed for
category IV) for horizontal or vertical
venting of the Vitodens boilers.
See tables 42. and 43. and contact
one of the suppliers (see listing on
right) to order.
Prior to installation, check that the
correct single-wall vent parts were
ordered and supplied.
See tables 42. and 43. for special
stainless steel single-wall vent pipe
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 (Vitodens 100-W only) and
starter stainless steel adaptors
(supplied by others, see tables 42. and
43.). 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" / 76mm.

(continued)
Note:
The Vitodens boiler has passed the
zero inches vent clearance to
combustibles testing requirements
dictated by the Harmonized Standard
ANSI Z21.13. CSA 4.9.2000 and
therefore is listed for zero clearance to
combustibles when vented with a
single wall special venting system. The
zero inches vent clearance to
combustibles for the Vitodens boiler
supercedes the clearance to
combustibles listing that appears on
the special venting system label.
