Refer to the Installation Instructions of the
Vitodens Venting System for details.
Note:
The Vitodens 100-W boiler has passed the
zero inches vent clearance to combustibles
testing requirements provided by the boiler
Harmonized Standard ANSI Z21.13. CSA
4.9.2005 and therefore is listed for zero
clearance to combustibles when vented
with a single wall special venting system
(AL-29-4C material) or UL/ULC-listed CPVC
gas vent material. The zero inches vent
clearance to combustibles for the Vitodens
100-W boiler supercedes the clearance to
combustibles listing that appears on the
special venting system label.
