Re
fer 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 dictated by the boiler latest
Harmonized Standard ANSI Z21.13. CSA 4.9.2007
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/PP(s) 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.
