General Installation Information (continued)
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 46. and 47. 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 46. and 47. 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 (for models WB1B 10-26/35
and WB2B 9-19/26/35) and starter
stainless steel adaptors (supplied by
others, see tables 46. and 47.). 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.
Note:
The Vitodens boiler has passed the
zero inches vent clearance to
combustibles testing requirements
dictated by the Harmonized Standard
ANSI Z21.13. CSA 4.9.7000 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
supersedes the clearance to
combustibles listing that appears on
the special venting system label.
